Hip Osteoarthritis: Treatment Without Surgery
The complete guide for adults: what hip arthritis is, why it hurts in the groin and at night, how it is diagnosed, the exercise and physical therapy every guideline puts first, a cane in the right hand, what medicines and injections can do, and when a hip replacement makes sense.
- Expert Reviewed
- Evidence Based
- Patient Focused
Hip osteoarthritis is the gradual loss of the smooth cartilage that lines the ball-and-socket joint of the hip, with bone spurs forming as the joint space narrows.1 It is common: in one US population study, about one person in four developed painful hip osteoarthritis by age 85.2 The usual signs are pain in the groin or thigh and stiffness after rest.1 Three major guidelines put education and exercise first; medicines and injections support that, and a hip replacement is for symptoms that stay severe despite it.3,4,5
Exercise is the core treatment for hip osteoarthritis at every stage, and walking, strengthening and tai chi all count.4,5 The benefit in trials is real but modest, so a program works best when it is supervised, kept up for the long term and combined with weight management where it applies.4,5,6 Hip pain after a fall that leaves you unable to bear weight needs emergency care.7
Key takeaways
- In a North Carolina study of adults aged 45 and older, the lifetime risk of painful hip osteoarthritis by age 85 was 25%.2
- The most common place to feel it is the groin, with pain that can spread to the thigh, buttock or knee.1
- A diagnosis can usually be made without an X-ray in people 45 or older with activity-related pain and morning stiffness of 30 minutes or less.5
- A Cochrane review found high-quality evidence that exercise reduces hip osteoarthritis pain by about 8 points on a 100-point scale, a modest but lasting effect.6
- A cane goes in the hand opposite the painful hip.8,9
- Gel (hyaluronic acid), PRP and stem cell injections and glucosamine are recommended against for the hip.4
- A hip replacement is considered when symptoms substantially affect your quality of life and nonsurgical care has not worked; age and weight alone do not rule it out.5,10
What is hip osteoarthritis, and how common is it?
The hip is a ball-and-socket joint: the ball is the top of the thighbone (the femoral head) and the socket, the acetabulum, is part of the pelvis.1 Both surfaces are covered with articular cartilage, which lets the bones move easily.1 In osteoarthritis the cartilage gradually wears away and becomes frayed and rough, the space between the bones narrows, and the bones can grow outward into bone spurs (osteophytes).1
Osteoarthritis can damage the whole joint, not only the cartilage: the lining, the bone, and the tendons and ligaments around it.12 It is the most common type of arthritis.12 For some people it stays mild and hardly affects the day; for others it causes significant pain and disability.12
How common is hip arthritis?
In the Johnston County Osteoarthritis Project, a long-running study of adults aged 45 and older in North Carolina, the lifetime risk of painful hip osteoarthritis was 25.3%, about one person in four by age 85.2 The risk was similar for men and women, across races and education levels, and with or without a past hip injury.2 It occurs most often in people 50 and older, though it can start younger.1
Who is more likely to get hip osteoarthritis?
- Age
The risk rises with age; osteoarthritis occurs most often after 50.1
- Being a woman
Women are more likely than men to have osteoarthritis, especially after age 50.12
- Family history
- A past hip injury
An earlier injury to the hip joint raises the risk.1
- Hip shape from birth
Developmental dysplasia of the hip, in which the joint did not form normally, is a risk factor.1
- Weight
Obesity is listed as a risk factor, though the North Carolina study found no link between body mass index and the lifetime risk of painful hip osteoarthritis.1,2
You can develop hip osteoarthritis with none of these.1
Hip arthritis symptoms: groin pain, stiffness and night pain
Pain is the most common symptom. It usually develops slowly and worsens over time, though it can come on suddenly.1
Common signs of hip osteoarthritis
- Pain in the groin or thigh that spreads to the buttock or the knee1
- Stiffness that is worse in the morning or after sitting or resting, usually easing within 30 minutes1,12
- Pain that flares after vigorous activity1
- Trouble bending to tie a shoe, rising from a chair or taking a short walk1
- Locking or sticking, or a grinding noise (crepitus) when the hip moves1
- Less movement in the hip, which can cause a limp1
Why does hip arthritis cause groin pain?
Pain from the hip joint itself is often felt most in the groin rather than over the side of the hip, and arthritis is often felt in the front of the thigh.7 It can also be felt in the inner thigh or buttock, or spread to the knee, so a sore knee is sometimes a hip problem.7,12 Pain over the outside point of the hip is more typical of bursitis, and hip pain can also come from the back.7,14
Hip arthritis pain at night: why it happens and how to sleep
Early on, the pain comes with activity and eases with rest; as the arthritis progresses, pain can come at rest and wake you at night.1,13 Pain that continues while resting, day or night, is one of the reasons surgeons consider a hip replacement.10 For sleep, lie on the side that does not hurt with a pillow between your legs.7 Night pain on the outside of the hip that is worst lying on that side is typical of trochanteric bursitis instead.14
When should you see a doctor for hip pain?
Contact your provider when osteoarthritis symptoms bother you or get worse.13 Some hip pain needs care sooner:7
| When | What it is for |
|---|---|
| Now: emergency care | Severe pain after a serious fall, a deformed, badly bruised or bleeding leg, being unable to bear weight, or worsening pain with trouble urinating or having a bowel movement.7 |
| Soon: your provider | Hip pain with fever or a rash, a warm, swollen, red joint, or sudden pain with sickle cell anemia or long-term steroid use.7,11 |
| After a week | Hip pain that has not improved after a week of home care, a new limp, or pain in both hips and other joints.7 |
| Anytime: a physical therapist | You can contact a physical therapist directly for an evaluation; every state allows some form of direct access.11,15 |
Who treats hip osteoarthritis?
Usually a team. A primary care doctor coordinates care; rheumatologists specialize in arthritis; orthopedic surgeons specialize in treatment and surgery for bone and joint diseases; physical therapists help improve joint function; occupational therapists teach ways to protect joints, reduce pain, manage daily activities and conserve energy; and dietitians help with weight.16 A physical therapist who finds that therapy alone is not helping refers you to an orthopedic specialist to discuss medicines, injections or surgery.11
How is hip osteoarthritis diagnosed? Do you need an X-ray?
Mostly from your history and an examination. There is no single test for osteoarthritis.16 The UK’s NICE guideline advises diagnosing it clinically, without imaging, in people who are 45 or older, have joint pain with activity, and have no morning stiffness or stiffness that lasts no longer than 30 minutes.5
- Your history. Your symptoms, how they began and your medical history.1
- The examination. Tenderness around the hip, how far it moves when you move it and when someone moves it for you, grating with movement, and pain when pressure is placed on the hip.1
- How you walk. Your gait, since a stiff, painful hip often changes it.1
- Other structures. Signs of injury to the muscles, tendons and ligaments around the hip, and your back and thighs, since a back problem can cause hip pain.1,7
- Tests if needed. Possibly an X-ray; blood tests and joint fluid only to rule out other causes such as rheumatoid arthritis, gout or infection.1,13,16
When do an X-ray or MRI help?
An X-ray of an arthritic hip may show a narrowed joint space, bone changes and bone spurs.1 But early damage does not usually show on X-rays, and some people have clear X-ray changes without symptoms, so the picture and the pain do not always match.13,16 NICE advises against routine imaging to diagnose osteoarthritis unless the features are atypical or suggest another diagnosis, and against routine imaging to follow it or to guide nonsurgical care.5 An MRI or CT scan is needed only occasionally, for example to evaluate a joint that is locking or giving way.1,16 X-rays do become part of the picture when a hip replacement is being considered.10
Hip arthritis vs. bursitis: how to tell the difference
Trochanteric bursitis is inflammation of a small fluid-filled sac over the bony point on the outside of the hip.14 Where the pain sits is the main clue:1,14
| Feature | Hip osteoarthritis | Trochanteric bursitis |
|---|---|---|
| Where it hurts | The groin or thigh, spreading to the buttock or knee1 | The point of the hip, spreading down the outside of the thigh14 |
| What makes it worse | Vigorous activity; stiffness after sitting or resting1 | Getting up after sitting, long walks, stairs and squatting14 |
| At night | Pain at rest and at night as it progresses1 | Typically worse at night, lying on that hip14 |
| Movement | Stiffness and lost motion, sometimes a limp1 | Tenderness when the point of the hip is pressed14 |
| X-ray | Narrowed joint space and bone spurs1 | Used to rule out other conditions14 |
A less common bursitis at the front of the hip (iliopsoas bursitis) does cause groin pain, so an examination settles which it is.14 Hip pain can also come from the lower back: our low back pain guide covers that side.7
Hip osteoarthritis treatment without surgery: what the guidelines say
There is no cure for osteoarthritis, but early treatment of hip osteoarthritis is nonsurgical, and it can lessen the condition’s impact on your life.1 Three major guidelines agree on the core: the international OARSI guideline names arthritis education and structured land-based exercise as the core treatments for hip osteoarthritis; the American College of Rheumatology and Arthritis Foundation strongly recommend exercise, self-management programs and, for people with overweight, weight loss; and NICE calls therapeutic exercise and weight management the core treatments, with information and support.3,4,5 These treatments can often delay surgery.13
| Treatment | What it involves | The evidence |
|---|---|---|
| Exercise | Strengthening, walking or other aerobic exercise, flexibility and balance work.4,16 | First line Strongly recommended (ACR); a core treatment (OARSI, NICE); high-quality evidence of a modest benefit.3,4,5,6 |
| Education and self-management | Learning about the condition and skills to manage it, often in a group program.4,16 | First line Strongly recommended (ACR); a core treatment (OARSI).3,4 |
| Weight loss | For people with overweight or obesity, a weight-loss goal with support.5 | Recommended Strongly recommended for the hip (ACR); a core treatment where appropriate (NICE).4,5 |
| Tai chi | Slow, gentle movement combined with breathing and relaxation.4 | Recommended Strongly recommended for knee and hip osteoarthritis (ACR).4 |
| A cane or other walking aid | Held in the hand opposite the painful hip.8 | Recommended Strongly recommended when the hip limits walking (ACR); NICE advises considering walking aids.4,5 |
| Heat or cold | Locally applied heat or cold packs.4,16 | For comfort Conditionally recommended (ACR).4 |
| Manual therapy | Hands-on mobilization, manipulation or soft-tissue work.5 | Add-on only NICE: only alongside exercise; ACR advises against adding it over exercise alone (conditional).4,5 |
| Acupuncture | Fine needles placed at set points.4 | Guidelines differ Conditionally recommended (ACR); not offered (NICE).4,5 |
| Massage | Soft-tissue massage.4 | Not recommended Conditionally recommended against for the hip (ACR).4 |
| TENS, ultrasound, laser | Electrical and other device-based treatments.5 | Not recommended NICE advises against them for lack of evidence.5 |
Does physical therapy help hip arthritis?
Exercise helps, and the evidence is honest about how much. A Cochrane review of land-based exercise found high-quality evidence from nine trials (549 people) that exercise reduced pain by about 8 points and improved function by about 7 points on 100-point scales, with the pain benefit lasting at least three to six months after supervised treatment ended.6 That is a modest average: for every six people who exercise, about one more has a meaningful benefit than would without it.6
Not every program does better than placebo. In an Australian trial of 102 people with painful hip osteoarthritis, 10 physical therapy sessions of education, manual therapy, home exercise and a walking aid did no better than a sham treatment of inactive ultrasound and gel, and mild side effects such as soreness were more common with the real treatment.17 Guidelines still recommend exercise; the ACR finds supervised programs more effective than exercise done alone at home, and NICE suggests considering supervised sessions.4,5 MedlinePlus advises that if therapy has not helped after 6 to 12 weeks, it likely is not going to.13
What happens at physical therapy for hip arthritis?
- A thorough examination. Your movement, strength and the daily activities that are hard for you.11
- An exercise program for you. Strengthening and aerobic exercise designed around your needs, taught so you can do it safely.11
- Hands-on treatment as an add-on. Manual therapy to improve motion, used alongside exercise rather than instead of it.5,11
- A walking aid if needed. Recommending a cane or walker if you need one.11
- Weight and daily life. Strategies for safe weight loss, and changes to your work area to ease strain on the hip.11
- A home program. Exercises to keep improving after your visits end, since long-term adherence increases the benefits.5,11
NICE also suggests combining exercise with education or a behavior-change approach in one package.5
Best exercises for hip arthritis
There is no single best exercise: the ACR guideline found the evidence insufficient to recommend one prescription over another, and for the hip it lists walking, strengthening, neuromuscular training and water exercise with no hierarchy among them.4 The best program is one you can keep doing, built from these types:4,5,16
| Type | Examples | What the guidelines say |
|---|---|---|
| Strengthening | Exercises with weights or bands for the muscles that support the hip16 | Strengthening the hip muscles helps keep the joint stable and can relieve pain18 |
| Low-impact aerobic | Walking, cycling, swimming, water aerobics16 | Walking was the exercise most often studied4 |
| Range of motion and stretching | Gentle stretches to keep the joint moving16 | Part of a well-rounded program16 |
| Balance and agility | Exercises to control and steady your body position4,16 | Conditionally recommended (ACR)4 |
| Tai chi | Slow, flowing movement with breathing4 | Strongly recommended for hip osteoarthritis (ACR)4 |
| Water exercise | Exercise in a pool, which lowers the stress on the joints16 | Often helpful (MedlinePlus); OARSI did not include it among its hip recommendations3,13 |
Hip exercises to do at home
Ask your doctor or physical therapist which exercises suit you before you start.18 Warm up first with 5 to 10 minutes of walking or a stationary bicycle.18 These six come from the AAOS hip conditioning program, a general program for the hip; two are stretches and four strengthen the muscles around the joint.18
Knee to chest
A stretch for the buttock muscles (gluteus maximus and medius).18
- Lie on your back on the floor with your legs straight.
- Bend one knee and hold your shin with both hands.
- Gently pull the knee toward your chest as far as it goes; hold 30 seconds, then relax 30 seconds.
The AAOS program: 2 sets of 4, daily. Keep your lower back pressed into the floor.18
Supine hamstring stretch
Stretches the back of the thigh.18
- Lie on the floor with both knees bent.
- Lift one leg, bring the knee toward your chest and clasp your hands behind the thigh (or loop a towel around it).
- Straighten the leg and gently pull it toward your head until you feel a stretch; hold 30 to 60 seconds.
The AAOS program: 2 sets of 4, daily. Do not pull at your knee joint.18
Side-lying hip abduction
Strengthens the gluteus medius on the outside of the hip.18
- Lie on your side with the painful leg on top and the bottom leg bent for support.
- Keep the top knee straight but not locked and slowly raise the leg to about 45 degrees.
- Hold 5 seconds, lower slowly and relax 2 seconds.
The AAOS program: 8 repetitions, 2 to 3 days a week. Begin with a weight that allows 8 repetitions and work up to 12; then add 1 pound and start again at 8. Do not turn the leg to lift it higher.18
Clamshell
Works the gluteal muscles at the side and back of the hip.18
- Lie on your side, the painful leg on top, hips slightly bent and knees bent about 90 degrees, stacked.
- Keeping your feet together, slowly lift the top knee as high as you can without moving your pelvis; hold 5 seconds.
- Lower the knee slowly to a count of 5.
The AAOS program: 1 set of 10 to 15 on each side, daily. Do not lean forward or back.18
Prone hip extension
Strengthens the gluteus maximus, the big buttock muscle.18
- Lie on your stomach on a firm surface with a pillow under your hips.
- Bend one knee to 90 degrees.
- Lift the leg straight up, then lower it to the floor to a count of 5.
The AAOS program: 8 repetitions, 2 to 3 days a week. Begin with a weight that allows 8 repetitions and work up to 12; then add 1 pound and start again at 8.18
Side-lying hip adduction
Strengthens the inner-thigh muscles.18
- Lie on the side of the painful leg with both legs straight.
- Bend the top leg and cross it over the bottom leg.
- Raise the bottom leg 6 to 8 inches off the floor, hold 5 seconds, lower slowly and rest 2 seconds.
The AAOS program: 8 repetitions, 2 to 3 days a week. Begin with a weight that allows 8 repetitions and work up to 12; then add 1 pound and start again at 8.18
How to progress hip exercises safely
- Start slowly
Begin any program slowly and give yourself time to adjust to the new level of activity.16
- Add load in small steps
In the AAOS program, add weight 1 pound at a time once 12 repetitions are easy, starting again at 8.18
- Give it weeks
The AAOS program runs 4 to 6 weeks, then continues 2 to 3 days a week as maintenance.18
- Expect some soreness at first
NICE advises that joint pain may increase when you start, and that regular, consistent exercise is still beneficial for the joints.5
- Know where your line is
The AAOS program says you should not feel pain during an exercise; the ACR notes there is no agreed pain level for exercising, so set yours with your clinician.4,18
- Keep it going
Long-term adherence to an exercise plan increases its benefits.5
Is walking good for hip arthritis?
For most people, yes. Walking is one of the low-impact activities NIAMS lists for osteoarthritis, and it was the aerobic exercise most often tested in the trials behind the ACR guideline.4,16 The federal Physical Activity Guidelines note that physical activity can decrease pain for people with osteoarthritis, and that any amount of activity has some health benefits.19
- How much to aim for
Adults need at least 150 to 300 minutes a week of moderate activity, like brisk walking, plus muscle strengthening at least 2 days a week; build up to it.16,19
- Lower the impact
Switching from high-impact activities such as jogging to lower-impact ones such as swimming or cycling puts less stress on the hip.1
- Shoes and surfaces
Wear flat, cushioned shoes, and stand on a cushioned surface if you have to stand for a long time.7
- Hills and stairs
Walk down hills rather than running down them, and cut back on activities that aggravate the hip, such as climbing stairs.1,7
- Use a cane if you need one
A cane can make walking safer and less painful.16
Does losing weight help hip arthritis?
For people with overweight or obesity, it is recommended. The ACR strongly recommends weight loss for knee and hip osteoarthritis, noting that losing 5% or more of body weight can be associated with changes in symptoms, with benefits increasing beyond that.4 NICE advises that weight loss improves quality of life and physical function and reduces pain, that any amount is likely to help, and that losing 10% of body weight is likely to be better than 5%.5 Losing weight reduces stress on the hip joint.1,16
The evidence is stronger for the knee than for the hip: OARSI lists dietary weight management as a core treatment for knee osteoarthritis but not for hip osteoarthritis.3 A physical therapist can teach exercise for safe weight loss, and a dietitian can help with nutrition.11,16
Cane for hip arthritis: which hand, and how to use one
Hold the cane in the hand opposite the painful hip: if your right hip hurts, the cane goes in your left hand.8,9 The cane moves forward with the painful leg and takes some of the pressure off it.9 The ACR strongly recommends a cane when hip osteoarthritis has a large enough effect on walking, stability or pain to warrant one.4
- Set the height. With the cane at your side, the handle should reach the crease of your wrist, with your elbow slightly bent as you hold it.8,9
- Step together. Move the cane forward the same distance as you step forward with the painful leg, putting some weight through the cane.9
- Finish the step. Step past the cane with the stronger leg.9
- Turn on the strong leg. Pivot on the stronger leg, not the painful one.9
- Stairs: up with the good, down with the bad. Hold the handrail; going up, lead with the stronger leg; going down, put the cane on the step first, then the painful leg.8,9
If you need more stability, a four-point (quad) cane can help, and a walker is another option.8,16 A long-handled reacher helps you pick things up from the floor or low shelves without the movements that hurt.1
Medicines for hip arthritis pain
Medicines are meant to support exercise, not replace it, and NICE advises using them at the lowest effective dose for the shortest possible time.5 The two main guidelines differ in places:4,5
| Medicine | ACR/Arthritis Foundation (2019) | NICE (2022) |
|---|---|---|
| Anti-inflammatory pills (NSAIDs: ibuprofen, naproxen) | Strongly recommended4 | Considered if topical medicines do not help, with a stomach-protecting medicine5 |
| Anti-inflammatory gels (topical NSAIDs) | Strongly recommended for the knee; the hip is not included4 | Considered for joints other than the knee5 |
| Acetaminophen (Tylenol) | Conditionally recommended; effects are very small4 | Not routinely offered; no strong evidence of benefit5 |
| Duloxetine | Conditionally recommended4 | Not covered in these recommendations5 |
| Tramadol and other weak opioids | Tramadol conditionally recommended4 | Not routinely offered5 |
| Stronger opioids | Conditionally recommended against4 | Not offered; the risks outweigh the benefits5 |
| Glucosamine | Strongly recommended against4 | Not offered; no strong evidence of benefit5 |
Over-the-counter pain relievers can cause side effects and interact with other medicines, so check with your doctor, and talk with your provider before taking an NSAID regularly.1,13 Do not take more than 4 grams (4,000 milligrams) of acetaminophen a day from all medicines combined.13
Hip arthritis injections: cortisone, gel and PRP
A steroid (cortisone) injection into the hip can relieve pain for a while. The ACR strongly recommends steroid injections for hip osteoarthritis and strongly recommends imaging guidance, such as ultrasound, for injections into the hip joint.4 NICE suggests considering one when other medicines are ineffective or unsuitable, or to support exercise, and says the relief is short-term, 2 to 10 weeks.5 OARSI did not include steroid injections among its recommendations for hip osteoarthritis.3
- Hyaluronic acid (gel) injections
Strongly recommended against for the hip (ACR); NICE advises not offering them for osteoarthritis.4,5
- Platelet-rich plasma (PRP)
Strongly recommended against for hip osteoarthritis (ACR), partly because preparations are not standardized.4
- Stem cell injections
Strongly recommended against for hip osteoarthritis (ACR).4
- Prolotherapy
Conditionally recommended against for hip osteoarthritis (ACR).4
Your doctor decides how many steroid injections you can have and how often.16
When do you need a hip replacement?
When the arthritis causes disability that nonsurgical treatment does not relieve.1 NICE suggests considering a referral when joint symptoms such as pain, stiffness and reduced function are substantially affecting your quality of life and nonsurgical care has not worked or is unsuitable.5
Signs a hip replacement may be worth discussing
The decision rests on pain and disability, not a severity score or your age. Surgeons recommend surgery based on pain and disability rather than age, there are no absolute age or weight limits, and most people who have the operation are 50 to 80.10 NICE advises using clinical assessment rather than scoring systems, and not excluding people because of age, sex, smoking, other conditions or body weight, while explaining that those factors can change the risks.5
For severe arthritis, surgery does more than exercise. In a Danish trial of 109 people aged 50 or older who had severe hip osteoarthritis and met the criteria for surgery, hip replacement improved pain and function on the Oxford Hip Score by 15.9 points at 6 months, against 4.5 with resistance training; 21% of the training group had a replacement within those 6 months.20 More than 450,000 hip replacements are done each year in the US, and serious complications such as joint infection occur in less than 2% of patients.10
Other operations exist: hip resurfacing caps the ball of the joint instead of removing it, and an osteotomy, which cuts and realigns bone, is used only rarely for osteoarthritis.1
How to manage a hip arthritis flare-up
Hip osteoarthritis pain tends to flare after vigorous activity.1 During a flare:
Steps for a hip arthritis flare
- Cut back on what set it off, such as stairs, long walks or long periods of standing1,7
- Keep moving within what the hip tolerates: NICE advises regular, consistent exercise even if it causes some pain at first5
- Use heat or cold: heat increases blood flow and flexibility, and cold numbs the area4,16
- Use a cane in the opposite hand while the hip is sore8,16
- Use pain medicine you have agreed with your clinician, at the lowest dose for the shortest time5
- Sleep on the other side with a pillow between your legs7
If flares keep coming or your plan is not working within the time you agreed, go back to your clinician: NICE advises seeking follow-up then.5 NICE also suggests a steroid injection can be considered to support exercise when other medicines do not help.5 Our guide to pacing and activity management covers how to spread activity across the day.
Living with hip arthritis at home and at work
- Around the house
Use a long-handled reacher for low shelves and the floor, and a chair with armrests to make standing up easier.1,9
- At work
If your job stresses the hip, adjust your work area or tasks; a physical therapist can suggest changes.11,13
- Standing
Avoid standing for long periods, stand with your weight even on both legs, and use a cushioned surface.7
- Daily tasks
An occupational therapist can teach ways to protect the joint, reduce pain and save energy during daily activities.16
- Support
Classes and self-management programs teach skills for living with osteoarthritis, and the ACR strongly recommends them.4,16
Does Medicare cover physical therapy for hip arthritis?
Yes, when it is medically necessary. Medicare Part B covers outpatient physical therapy, and a doctor or another provider such as a nurse practitioner or physician assistant must certify that you need it.21
| Coverage | What to know |
|---|---|
| Original Medicare, Part B | After the Part B deductible you pay 20% of the Medicare-approved amount, with no yearly limit on medically necessary outpatient therapy.21 |
| The 2026 KX threshold | Once therapy costs pass $2,480 for physical therapy and speech-language pathology combined, the clinic adds the KX modifier to confirm the therapy is medically necessary.22 |
| Occupational therapy | Has its own, separate $2,480 threshold in 2026.22 |
| Targeted medical review | Claims can be reviewed once costs reach $3,000.22 |
| Medicare Advantage | Plans must cover all medically necessary services Original Medicare covers, but may require prior authorization or in-network providers.23 |
| Seeing a therapist first | Every state allows some form of direct access to a physical therapist, though some states still attach conditions to treatment without a referral, and Medicare needs a provider to certify that you need therapy.15,21 |
Hip arthritis myths and facts
- Myth: exercise wears out an arthritic hip
Exercise is a core treatment in all three major guidelines, and NICE advises that regular, consistent exercise benefits the joints.3,4,5
- Myth: rest protects the joint
Less activity can lead to muscle weakness, which puts more stress on the joint.12
- Myth: the X-ray shows how much it should hurt
Some people have clear X-ray changes and no symptoms; care is guided by symptoms and function.5,13
- Myth: glucosamine rebuilds cartilage
The ACR strongly recommends against glucosamine, and NICE finds no strong evidence of benefit.4,5
- Myth: gel shots work for the hip like the knee
Hyaluronic acid injections are strongly recommended against for the hip.4
- Myth: you are too young or too heavy for a new hip
There are no absolute age or weight limits for hip replacement.5,10
- Myth: a cane means giving in
A cane is strongly recommended when the hip limits walking.4
Hip arthritis goals worth setting
Tie my shoes and put on socks · Get up from a low chair without pushing · Walk to the end of the block and back · Climb the stairs at home · Sleep through the night
Improve hip range of motion · Strengthen the gluteus medius
The first line names what hip osteoarthritis takes away, from tying a shoe and rising from a chair to a short walk.1 If your goals read like the second line, ask for them in daily-life terms: NICE advises that care be guided by symptoms and physical function.5
How do you find a physical therapist for hip arthritis?
All physical therapists are trained to treat osteoarthritis. You may prefer a board-certified clinical specialist, one who has completed a residency or fellowship in orthopedic or geriatric physical therapy, or one who focuses on osteoarthritis.11 Ask about their experience with osteoarthritis, and be ready to describe your symptoms and what makes them better or worse.11

Frequently Asked Questions
Is walking good for hip arthritis?
For most people, yes. Walking is a low-impact activity recommended for osteoarthritis, and physical activity can decrease osteoarthritis pain.16,19 Start slowly, wear cushioned shoes, and use a cane in the opposite hand if you need one.7,8,16
What are the best exercises for hip arthritis?
No single exercise is best: walking, strengthening, neuromuscular training and water exercise are all options for the hip, and tai chi is strongly recommended.4 Strengthening the muscles around the hip, such as side-lying leg raises and clamshells, helps keep the joint stable.18
Does physical therapy help hip arthritis?
Exercise helps modestly: a Cochrane review found high-quality evidence that it reduces pain and improves function, by about 8 and 7 points on 100-point scales.6 Supervised exercise does better than exercise alone at home, and if therapy has not helped after 6 to 12 weeks, it likely is not going to.4,13
Why does hip arthritis cause groin pain?
Pain from the hip joint itself is often felt most in the groin, and the groin is the most common place to feel hip osteoarthritis.1,7 It can spread to the thigh, buttock or knee.1
Which hand do you hold a cane in for hip arthritis?
The hand opposite the painful hip: for a painful right hip, hold the cane in your left hand.8,9 The handle should reach the crease of your wrist.8
Do cortisone injections help hip arthritis?
They can relieve pain for a short time: NICE says 2 to 10 weeks.5 The ACR strongly recommends them for the hip, given with imaging guidance.4
Do gel or PRP injections help hip arthritis?
They are not recommended. The ACR strongly recommends against hyaluronic acid, platelet-rich plasma and stem cell injections for hip osteoarthritis, and NICE advises not offering hyaluronic acid injections.4,5
When do you need a hip replacement for arthritis?
When pain, stiffness or reduced function substantially affect your quality of life and nonsurgical treatment has not worked.5 Pain at rest or at night and pain that limits walking or bending are common reasons.10
