Abstract
Objective:To investigate the clinical efficacy of arthroscopic autologous tendon reconstruction of the medial patellofemoral ligament for the treatment of recurrent patellar dislocation.Method:Retrospective analysis 19 cases with recurrent patellar dislocation in our department,they were selected from June 2014 to March 2016.Surgery with arthroscopic lateral collateral ligament release, ipsilateral hamstring tendon autograft for the reconstruction of the medial patellofemoral ligament.Postoperative they were given normal joint function exercise to assess postoperative pain,weakness, patellar tilt test and fear the changes.Postoperative joint function improve was evaluated by Lyshom and Kujala knee score and Insall standard.Result:All patients were followed up,preoperative knee score Lyshom for (68.3±1.4)score,postoperative was (95.4±1.8) score;Kujala score preoperative was (63.2±2.3) score and postoperative was (92.4±2.5) score, the differences were statistically significant(P<0.05). Insall curative effect standard, the excellent and good rate of 94.7%.All the patients after joint pain and weakness <br> symptoms improved significantly,patellar tilt, fear the negative,no joint again dislocation.Conclusion:In to control the disease under the premise that arthroscopic medial patellofemoral ligament reconstruction in the treatment of recurrent patellar dislocation is a good surgery method. Arthroscopic lateral collateral ligament release, intraoperative double patellar ligament reconstruction, patella end metal anchor nail fixed, flexion of the knee joint 60° with a femoral side fixation increased the patellar stability and improve the reliability of the operation.关键词
