Clinical efficacy of 35 routine arthroscopic MPFL reconstruction with recurrent patellar dislocation
复发性髌骨脱位35例行关节镜下MPFL重建的临床疗效探讨

摘要

目的 探讨复发性髌骨脱位行关节镜下MPFL重建的临床疗效。方法 对2021年5月-2022年5月本科接诊复发性髌骨脱位患者（n=35）实施关节镜下MPFL重建治疗。比较患者在术前以及术后12个月的关节功能、髌骨CT测量值差异。结果 术后12个月内，所有患者再未出现髌骨再脱位、髌骨半脱位、错动等情况，患者的Lysholm评分、Kujala评分明显提升，膝关节屈伸活动度同常人一致，无肿胀、疼痛等现象，能够进行正常体育运动且髌股适合角低于术前、外侧髌股角高于术前，差异有统计学意义（P<0.05）。结论 采用关节镜下MPFL重建的方式对复发性髌骨脱位患者进行治疗后，明显改善了患者的髌股关节功能，治疗期间的安全性也得到了大幅提升，病情复发率直线下降。

Abstract

Objective To investigate the clinical efficacy of arthroscopic MPFL reconstruction with recurrent patellar dislocation.
Methods: Conduct arthroscopic MPFL reconstruction therapy in undergraduate patients with recurrent patellar dislocation (n=35) from May 2021 to May 2022. Comparing patient differences in joint function, patellar CT measurements before and 12 months.
Results: within 12 months after surgery, all patients have no patellar dislocation, patellar dislocation, dislocation, etc., patients with Lysholm score, Kujala score significantly, knee flexion and extension activity with the same, no swelling, pain, can normal sports and patellar Angle is lower than preoperative, lateral patellofemoral Angle is higher than preoperative, the difference (P <0.05).
Conclusion  : The treatment of recurrent patellar dislocation by arthroscopic MPFL reconstruction significantly improved the patellofemoral joint function, and the safety during the treatment period was also greatly improved, and the recurrence rate plummeted.
