Exercise May Not Help Hip Arthritis as Much as Patients Expect

Topic: Health

A new review of 18 clinical trials found that exercise may provide only small improvements in pain and physical function for people with hip osteoarthritis. The researchers say stronger evidence is needed before firm conclusions can be drawn.

Hip osteoarthritis affects millions of people worldwide and is a major cause of long-term pain and disability. Exercise is commonly recommended as one of the first treatments for reducing symptoms and maintaining mobility.

Researchers from the University of Sydney and University of Melbourne analyzed 18 clinical trials involving 1,368 participants. Most were women (63%), and their ages ranged from 53 to 74. The exercise programs differed considerably across the studies, lasting anywhere from two to 52 weeks and including strengthening exercises, aerobic activity, and mind-body approaches.

The review found that exercise probably lowered pain by about 7 points on a 100-point scale, but this may not be enough for patients to notice a meaningful improvement in daily life. Physical function followed a similar pattern, with only modest average gains. The researchers noted that the thresholds used to define a meaningful improvement were developed mainly from studies involving knee osteoarthritis or mixed groups of osteoarthritis patients.

The findings do not suggest that exercise is ineffective or that it should no longer be recommended. Physical activity provides many health benefits beyond arthritis, costs relatively little, and is unlikely to cause harm.

Why It Matters

This study matters because hip osteoarthritis affects millions of people in India, and understanding the effectiveness of exercise as a treatment can help patients make informed decisions about their care.
