Increased physical activity is an effective treatment for knee osteoarthritis that causes knee pain. However, due to the coronavirus disease 2019, noncontact and non-face-to-face interventions have increased, but the quality of evidence supporting their effectiveness remains unclear. The purpose of the study was to assess the quality of evidence of the effects of non-face-to-face and noncontact interventions on knee pain and physical activity in older adults with knee osteoarthritis. A meta-analysis was conducted to determine the effects of different intervention methods (education and exercise). The Cochrane Central Register of Controlled Trials, PubMed, Cumulative Index to Nursing and Allied Health Literature, and Physiotherapy Evidence Database were systematically searched. Four randomized controlled trials were included in the analysis. The meta-analysis demonstrated that the educational intervention group was significantly effective, although supportive evidence was low quality. Educational intervention may be effective, but the effects need to be confirmed by higher quality clinical trials.

增加体力活动是治疗导致膝关节疼痛的膝骨关节炎的有效方法。然而，由于 2019 冠状病毒病，非接触和非面对面的干预措施有所增加，但支持其有效性的证据质量仍不清楚。该研究的目的是评估非面对面和非接触式干预对患有膝骨关节炎的老年人膝痛和身体活动影响的证据质量。进行了荟萃分析以确定不同干预方法（教育和锻炼）的效果。系统地检索了 Cochrane 对照试验中央登记册、PubMed、护理和相关健康文献的累积索引以及物理治疗证据数据库。分析中包括四项随机对照试验。荟萃分析表明，教育干预组显着有效，尽管支持性证据质量较低。教育干预可能有效，但效果需要更高质量的临床试验来证实。
