BackgroundKnee osteoarthritis (KOA) is a worldwide disease and more and more people are suffered from it. With the increasing number of patients, it brings a huge burden on social economy and security system. There are varieties of methods to cure KOA, such as Traditional Chinese Medicine and surgery. Needle knife therapy plus Sodium hyaluronate Injection is one of the prevalent treatments for KOA. Therefore, we perform a systematic review and meta-analysis to evaluate the evidence for the treatment of needle knife therapy plus sodium hyaluronate Injection.MethodsRandomized controlled trials will be used to compare the effect of needle knife therapy plus sodium hyaluronate injection with needle knife alone for KOA patients. Six studies will be included in this meta-analysis, and the relative risk and weight mean difference with 95% CI for the Lysholm knee score, visual analogue scale, and effective rate will be evaluated by using RevMan 5.3 software. Besides, the bias assessment of the included studies will be evaluated using the Cochrane risk of bias tool, and the Grading of Recommendations, Assessment Development, and Evaluation system will be applied to assess the overall quality of the evidence.ResultsFrom the study we will assess the effectiveness, safety of needle knife therapy plus sodium hyaluronate injection on joint pain relief and functional improvement in patients with KOA.ConclusionThe study will provide a new evidence to confirm the effect of needle knife therapy plus sodium hyaluronate injection on KOA, which can further guide the selection of therapy.Prospero Registration NumberCRD42020169602.
