Background: Chondromalacia patellae (CP) is a common and main cause of knee pain, the prevalence of the disease in the general population is as high as 36.2%, especially in middle-aged patients aged between 30 and 40 years (up to 50%). The use of manual therapy (MT) to dredge the meridians and muscles around the knee joint and stimulate the relevant acupoints can play vital roles in relieving pain and improving function. The purpose of this study is to assess the effectiveness, safety and further comprehensively, completely and multi-dimensionally explain the mechanism and treatment advantages of MT for CP.
Methods: A prospective randomized controlled clinical trial design was used to study the efficacy and safety of MT in the treatment of CP. One hundred and twenty cases of CP patients will be recruited and randomly divided into experimental group and control group according to 1:1. The control group: sodium hyaluronate; experimental group: MT added on the basis of the control group. Both groups will receive standard treatment for 4 weeks and followed up for 3 months. And at the same time, pay attention to its efficacy and safety indicators. Observation indicators include: the visual analogue scale pain score; the Western Ontario and McMaster Universities Arthritis Index scores; the Lysholm scores, and Bristol scores, adverse reactions, etc. Data analysis was performed using SPSS 25.0 software.
Discussion: This study will precisely evaluate the effectiveness and safety of MT in the treatment of CP. The results of this experiment will provide more reliable clinical basis for the selection of MT for patients with CP.
