Key Takeaway
Consider exercise therapy as the most consistent non-pharmacological intervention for elderly patients with knee osteoarthritis.

This meta-analysis synthesized data from 13 randomized controlled trials to evaluate the efficacy of various non-pharmacological interventions for elderly patients with knee osteoarthritis (KOA). The analysis focused on primary outcomes of pain and physical function across three main categories: exercise therapy, TCM non-pharmacological therapies, and physical therapy modalities.

Exercise therapy showed significant relief in pain and improvement in physical function with an effect size of SMD = -0.66 (95% CI: -1.25 to -0.06, I2 = 80%). In contrast, TCM non-pharmacological therapies showed significant beneficial effects but with a smaller magnitude (SMD = -0.21; 95% CI: -0.54 to 0.12, I2 = 72%). Physical therapy modalities did not show a statistically significant difference (SMD = -0.16; 95% CI: -0.43 to 0.10, I2 = 65%).

The authors noted high heterogeneity in the results due to diverse outcome measurement scales and variations in intervention intensity, duration, and protocols. Despite these limitations, exercise therapy emerged as the most consistent and reliable non-pharmacological intervention for this population. Clinical application should consider these findings while acknowledging the variability in reported trial protocols.

How this fits prior evidence

This meta-analysis extends existing evidence regarding non-pharmacological management of knee osteoarthritis. It complements previous findings on Wuqinxi for joint function and acupuncture for chronic knee pain by providing a broader look at exercise and physical therapy modalities. While probiotics were previously noted as a potential adjunct with limited evidence, this study identifies exercise therapy as a more consistent intervention for improving pain and function in elderly patients.

Living with knee osteoarthritis can make every step feel like a struggle. For many older adults, finding a way to manage constant pain while staying mobile is a daily challenge. Recent research looked at different ways to help these patients without using medication.

The analysis of 13 trials found that exercise therapy was the most consistent and reliable method for reducing pain and improving physical function. While other methods like traditional Chinese medicine therapies showed some benefit, they were not as consistent as exercise. Physical therapy modalities did not show a statistically significant difference in results.

It is important to note that these findings come from a wide range of studies with different intensities and durations. Because the programs varied so much, the results for certain treatments are less certain. However, the evidence points strongly toward exercise as a reliable tool for improving daily life.

What this means for you:
Exercise therapy is the most consistent way to reduce pain and improve movement for seniors with knee osteoarthritis.

Common questions

Is exercise effective for seniors with knee osteoarthritis?

Yes, the data shows that exercise therapy significantly relieved pain and improved physical function for elderly patients. It was found to be the most consistent and reliable non-pharmacological option among the methods studied.

How do other treatments compare to exercise for knee pain?

While traditional Chinese medicine non-pharmacological therapies showed some beneficial effects, they were not as consistent as exercise. Physical therapy modalities did not show a statistically significant difference in improving pain or function.

Are there any risks to using these physical therapies?

The study did not report any specific adverse events, serious side effects, or issues with tolerability for the patients participating in these programs. You should talk to your doctor about which specific program is safest for you.

BACKGROUND: Knee osteoarthritis (KOA) is highly prevalent in the elderly. Non-pharmacological treatments are recommended as first-line management, but high-quality evidence synthesis is lacking. METHODS: We conducted a systematic review and meta-analysis following Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines. Databases were searched from January 2002 to July 2025. Two reviewers independently screened literature, extracted data, and assessed risk of bias using Cochrane Risk of Bias 2.0. Meta-analysis was performed using a random-effects model. RESULTS: A total of 13 randomized controlled trials were included in this meta-analysis. Exercise therapy significantly relieved pain and improved physical function in elderly patients with KOA (standardized mean difference [SMD] = -0.66, 95% confidence interval (CI): -1.25 to -0.06, I2 = 80%) (after sensitivity analysis). TCM non-pharmacological therapies also yielded significant beneficial effects (SMD = -0.21, 95% CI: -0.54 to 0.12, I2 = 72%), whereas physical therapy modalities showed no statistically significant difference (SMD = -0.16, 95% CI: -0.43 to 0.10, I2 = 65%). High heterogeneity was mainly attributed to diverse outcome measurement scales and intervention intensity, duration, and protocols. CONCLUSION: Non-pharmacological interventions effectively relieve pain and improve function in elderly KOA patients. Exercise therapy is the most consistent and reliable intervention.
