Exercise for Hip Osteoarthritis: Small Gains, Still Worth Discussing

If you’ve been told to exercise for hip osteoarthritis, the advice can sound oddly confident. The updated Cochrane review finds small average gains in pain and function in some comparisons. Yet the American College of Rheumatology’s 2026 guideline summary strongly recommends exercise for hip and knee osteoarthritis. How can both be true?

Because a recommendation isn’t a promise that every sore hip will improve by a particular number of points. It’s a decision about a useful part of care, adjusted to the person doing it. And the studies measured symptoms and function - not whether movement grows new cartilage. This article concerns adults with hip osteoarthritis, not hip pain that hasn’t been assessed.

What the hip studies actually tested

#

The 2025-updated Cochrane synthesis included 18 studies and 1,368 adults. Its programs were planned, structured, repetitive and land-based. They varied considerably in type and delivery. That distinction matters if somebody tries to put the review’s numbers on swimming, a casual walk or a particular set of home exercises. The review doesn’t give those activities the same measured effect.

Against no treatment, usual care or limited education, exercise probably reduced pain by an average 7.2 points on a 0-to-100 scale and improved function by 8.8 points. Those figures came from 10 studies involving 494 adults. For context, the review used 12 points for pain and 13 for function as meaningful between-group differences. The average improvements fell short of those marks. That doesn’t mean nobody felt better; it means the average group difference was small, and you can’t turn it into a forecast for one person. Cochrane’s current plain-language results set out both the comparisons and their thresholds.

But change the comparison and the picture changes too. In two studies with 123 adults, exercise versus a dummy treatment may have had little or no effect on pain; function was 7.4 points better on a 0-to-100 scale, short of that comparison’s 13-point meaningful difference. And in seven add-on studies involving 751 adults, exercise plus another treatment probably made little or no average difference in pain, function or well-being against that other treatment alone. These aren’t interchangeable verdicts on all movement. The dummy-treatment evidence is thin, while an add-on comparison asks a different question from exercise versus little or no care. Source: updated Cochrane review.

There are limits to the numbers, too. Most participants knew whether they were exercising, pain and function were self-reported, and several studies were small. Programs and participants differed, with few younger adults studied. So a tidy claim about the best routine - or a guaranteed response to one - would say more than this evidence does. Cochrane explains those limitations.

Why the recommendation is still strong

#

The ACR’s posted 2026 recommendation summary rates exercise a strong recommendation for knee and hip osteoarthritis, with moderate certainty. It’s a summary approved by ACR’s board, not a claim that the full guideline manuscript has already been published. It also puts care in a wider frame: personal preferences, symptom severity, other conditions, contraindications and access all matter. Physiotherapy referral is advised when limited function, worsening pain or fatigue gets in the way of activity.

The UK’s NICE guidance likewise offers tailored therapeutic exercise to people with osteoarthritis and describes exercise as a core part of management (alongside information and, when appropriate, weight management). Supervised sessions are worth considering. That’s a more useful message than “just do more”: find movement that addresses what you can and can’t do, then adjust it when your hip objects.

A stronger guideline recommendation and a modest hip-specific average can sit together. The guideline is about care as a whole; the Cochrane comparisons are about measured outcomes in particular trials. Neither says you must abandon pain treatment, nor that exercise has to earn its place by rebuilding a joint.

Symptoms aren’t cartilage

#

It’s easy to hear “good for your joints” and imagine damaged cartilage knitting itself back together. But the hip review evaluated pain, physical function, well-being and other participant outcomes, including withdrawals and unwanted events. It didn’t test cartilage restoration. The rationale for exercise includes muscle strength, movement and confidence in activity - not proof of structural repair.

That matters when judging progress. Getting out of a chair with less difficulty, walking with more confidence, or managing an activity that had become awkward can matter even without a change in the underlying joint structure. I’m not suggesting those improvements are guaranteed; I’m saying symptoms and function are the right things to discuss with a clinician, rather than looking for an unsourced “cartilage regrowth” promise. Cochrane addresses symptom and function outcomes, while NICE says management should be guided by symptoms and physical function.

Making a plan that doesn’t ignore pain

#

Start with a question for your clinician or physical therapist: which activity is difficult for me now, and what kind of exercise could help me work on it safely? NICE mentions local muscle strengthening and general aerobic fitness as examples of tailored therapeutic exercise. That isn’t a prescription for a named move, a fixed schedule or a required number of repetitions. If balance, a recent injury or surgery, or another significant health condition complicates activity, ask for an individualized plan (the hip trials weren’t designed to establish one universal routine). The ACR summary explicitly calls for decisions that account for other conditions and risk factors.

Some discomfort when beginning is possible, according to NICE. But that isn’t an instruction to grind through worsening pain. The ACR’s exercise guidance says to start slowly; if symptoms worsen, reducing resistance or taking longer breaks can help, and persistent worsening is a reason to speak with a physical therapist. A flare that doesn’t settle, a new limitation or a different sort of pain deserves a fresh look rather than an automatic increase in effort.

If your physical therapist gives you band exercises for home, a graded set such as the THERABAND resistance band set (affiliate link) lets you follow their progression. Don’t jump to a stronger band on your own.

And no, exercise doesn’t have to replace other care. The ACR summary describes multimodal management that can include medicines. Don’t change prescribed pain medication on the strength of an exercise article. If symptoms seriously affect quality of life despite non-surgical care, NICE says joint-replacement referral may be considered; exercise evidence isn’t a reason to indefinitely defer that conversation.

One boundary matters more than any routine: not every painful hip is osteoarthritis. Sudden hip pain after an injury when you can’t bear weight, or a hot, swollen hip with fever, calls for urgent medical advice rather than an exercise experiment, according to the NHS Dynamic Health physiotherapy service. Rapid worsening or unusual symptoms also merit assessment (NICE). And if you’re pregnant or breastfeeding, or managing a complex condition, ask your clinician or physical therapist to tailor activity; the hip review doesn’t establish a special safety profile for those circumstances.

The practical takeaway

#

Exercise for diagnosed hip osteoarthritis has evidence for small average pain and function gains against limited or usual care, weaker pain evidence against dummy treatment, and no demonstrated extra average gain in the add-on comparisons. That’s less dramatic than a cartilage-repair pitch. It’s also not a reason to write off a tailored plan before you’ve discussed what you want to be able to do. Cochrane’s updated review supplies the comparison-specific estimates; the ACR summary and NICE guidance explain why individualized exercise still belongs in the conversation.

Safety isn’t a footnote here. Cochrane says adverse-event evidence is very uncertain for exercise against dummy treatment or no/usual care, and a review of harms reporting in hip-exercise trials found that reporting was inconsistent. Take a worsening response seriously and get help adjusting the plan - don’t mistake a lack of good harms data for proof that nothing can go wrong.
