Osteoarthritis: Exercise Therapy Offers Minimal, Short-Term Relief – Review

A large-scale review of existing research suggests that exercise therapy may offer only limited and short-lived relief from osteoarthritis pain, and in some cases, may not be significantly more effective than no treatment at all. The findings, published in the open access journal RMD Open, are prompting a re-evaluation of exercise as a universal first-line treatment for the degenerative joint disease that affects millions worldwide.

Osteoarthritis, characterized by the breakdown of cartilage in joints, causes pain, stiffness, and reduced mobility. Exercise has long been a cornerstone of management strategies, recommended to strengthen muscles around the joint, improve range of motion, and reduce pain. However, a growing body of evidence has questioned the extent and durability of these benefits. This latest analysis, an “umbrella review” encompassing multiple systematic reviews and randomized clinical trials, aims to provide a more comprehensive picture.

What the Review Examined

Researchers, led by Tim Schleimer and colleagues, scoured research databases for relevant studies published up to November 2025. Their analysis included five systematic reviews encompassing 8,631 participants, as well as 28 randomized clinical trials involving an additional 4,360 individuals with knee, hip, hand, or ankle osteoarthritis. The team standardized data across studies to a 0-100 scale and used a statistical method called random-effects meta-analysis to combine the results. They also assessed the certainty of the evidence using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. The study is available on PubMed.

Small Benefits, Low Certainty

The pooled analysis revealed small, short-term reductions in knee osteoarthritis pain with exercise compared to placebo or no treatment. However, the researchers emphasize that the certainty of this evidence was “very low.” these benefits appeared even smaller in larger studies and those that followed patients for longer periods. For hip osteoarthritis, the evidence suggested negligible improvement, while hand osteoarthritis showed small effects.

Importantly, the review found that exercise generally performed similarly to other common treatments, including patient education, manual therapy, pain medications, steroid or hyaluronic acid injections, and even arthroscopic knee surgery. In some cases, exercise was less effective than more invasive procedures like knee osteotomy (bone remodeling surgery) or joint replacement, particularly over the long term. More details on the study methodology and findings can be found in RMD Open.

What Does This Mean for Patients?

These findings don’t mean exercise is *harmful* for osteoarthritis. Rather, they suggest that its benefits may be more modest and less consistent than previously believed. The researchers caution against the “universal promotion” of exercise as a first-line treatment for all patients.

“We found largely inconclusive evidence on exercise for osteoarthritis, suggesting negligible or, at best, short-lasting small effects on pain and function across different types of osteoarthritis compared with placebo or no treatment,” the authors wrote. “These effects appear less pronounced in larger and longer-term trials.”

The researchers stress that exercise offers numerous health benefits beyond pain relief, such as improved cardiovascular health, mood, and overall well-being. It can still be a valuable component of a comprehensive osteoarthritis management plan. However, the decision to pursue exercise therapy should be made on an individual basis, in consultation with a healthcare professional.

Limitations and Considerations

The researchers acknowledge several limitations to their analysis. They prioritized specific reviews for inclusion, which means some relevant studies may have been excluded. Many studies lacked direct comparisons between exercise and other treatments, and participants varied widely in symptom severity. Some trials also allowed participants to continue with other treatments alongside exercise, making it difficult to isolate the effects of exercise alone.

It’s also crucial to understand the difference between correlation and causation. While the review found an association between exercise and pain reduction, it doesn’t prove that exercise *causes* pain reduction. Other factors, such as individual motivation, adherence to exercise programs, and the presence of other health conditions, may also play a role.

The Broader Context of Osteoarthritis Management

Osteoarthritis is a complex condition with no single cure. Management typically involves a combination of approaches, including lifestyle modifications (weight management, activity modification), physical therapy, pain medications, and, in some cases, surgery. The National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) provides comprehensive information on osteoarthritis and its management.

How Certainty of Evidence Impacts Recommendations

The GRADE methodology used in this review highlights the importance of considering the certainty of evidence when making clinical recommendations. “Very low” certainty, as found for knee osteoarthritis pain, means that further research is needed to confirm the benefits of exercise. This doesn’t necessarily mean exercise is ineffective, but it does mean that healthcare professionals should be cautious about recommending it as a standalone treatment.

What Comes Next: Research Priorities

The authors of the review call for a shift in research priorities. They suggest that future studies should focus on identifying which types of exercise are most effective for specific types of osteoarthritis, and for which patients. They also emphasize the require for longer-term trials to assess the durability of exercise benefits. Research should explore the optimal combination of treatments for osteoarthritis, including exercise, medication, and other therapies.

the goal is to develop more personalized and effective treatment strategies that can help people with osteoarthritis live fuller, more active lives. Shared decision-making between clinicians and patients, weighing the potential benefits and risks of different treatment options, will be crucial in achieving this goal.
