For decades, exercise has been a cornerstone recommendation for managing osteoarthritis, a degenerative joint disease affecting millions. However, a sweeping new analysis of existing research is challenging that long-held belief, suggesting that exercise therapy may offer only minimal and short-lived relief from pain and mobility issues associated with the condition. In some cases, the benefits may be no better than receiving no treatment at all.
The comprehensive review, published in the open-access journal RMD Open, pooled data from dozens of clinical trials involving over 13,000 participants. Researchers found that while exercise might provide a small reduction in knee osteoarthritis pain compared to placebo or no treatment, the effect was often small and tended to diminish over time, particularly in larger and longer-term studies. Evidence for hip and hand osteoarthritis was similarly underwhelming.
“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 study authors wrote. “These effects appear less pronounced in larger and longer-term trials.”
Challenging Conventional Wisdom
Osteoarthritis, characterized by the breakdown of cartilage in joints, is a leading cause of disability worldwide. Traditional treatment approaches have often prioritized exercise as a first-line intervention, aiming to strengthen muscles around the affected joints, improve range of motion, and reduce pain. However, this new analysis raises questions about the extent to which these benefits are truly realized.
The researchers emphasize that their findings don’t necessarily mean exercise is *harmful* for individuals with osteoarthritis. Rather, they suggest that the automatic recommendation of exercise as the primary treatment strategy may need to be re-evaluated. The study highlights the need for a more nuanced approach, considering individual patient needs and preferences.
How Did They Reach This Conclusion?
To arrive at their conclusions, the research team conducted an “umbrella” review, meaning they synthesized the results of multiple existing systematic reviews and randomized controlled trials. They searched research databases for studies published through November 2025, ultimately including 5 systematic reviews encompassing 8,631 participants and 28 randomized clinical trials involving 4,360 individuals with knee, hip, hand, or ankle osteoarthritis.
The analysis compared exercise to a range of other interventions, including placebo, usual care, no treatment, medications, manual therapy, steroid or hyaluronic acid injections, and even surgery. The results indicated that exercise generally performed similarly to many of these other treatments, though the certainty of the evidence varied.
In some specific cases, exercise was found to be less effective over the long term than surgical interventions like knee bone remodeling surgery (osteotomy) or total joint replacement.
What Does This Mean for Patients?
The findings underscore the importance of shared decision-making between clinicians and patients. Rather than a one-size-fits-all approach, treatment plans should be tailored to the individual, taking into account the potential benefits and risks of various options, as well as the patient’s overall health status and goals.
“Clinicians and patients should engage in shared decision-making, weighing the worthwhileness of exercise effects on pain and function alongside secondary health benefits, safety, low-cost profile, care stage, and alternative treatment options,” the researchers advise.
It’s crucial to remember that exercise offers numerous health benefits beyond joint pain relief, including improved cardiovascular health, mood, and overall well-being. For some patients, these benefits may outweigh the limited impact on osteoarthritis symptoms, making exercise a worthwhile pursuit.
Limitations and Future Research
The study authors acknowledge certain limitations. The inclusion criteria prioritized specific types of reviews, potentially excluding some relevant studies. Many of the included trials lacked direct head-to-head comparisons between exercise and other treatments, and participant characteristics varied widely. Some trials also allowed for the use of additional treatments alongside exercise, making it difficult to isolate the specific effects of exercise alone.
Despite these limitations, the researchers argue that their findings highlight the need for a shift in research priorities. Future studies should focus on identifying which types of exercise, if any, are most effective for specific subgroups of patients with osteoarthritis, and under what conditions. Further investigation is also needed to explore the optimal combination of treatments for managing this complex condition.
The researchers also point out that the certainty of evidence was often low, meaning that more high-quality research is needed to confirm these findings. The study serves as a reminder that medical recommendations are constantly evolving as new evidence emerges, and that a critical and evidence-based approach is essential for providing the best possible care to patients with osteoarthritis.
