Research Progress on Return to Sport after Lateral Patellar Dislocation Surgery

外侧髌骨脱位(lateral patellar dislocation, LPD)是青少年中常见的膝关节运动损伤，发病率呈逐年上升趋势。内侧髌股韧带重建(medial patellofemoral ligament reconstruction, MPFLR)作为治疗LPD的主流术式可取得良好的临床疗效，显著降低再脱位率，但在患者重返运动(return to sport, RTS)水平方面仍存在争议，尤其当合并复杂骨性手术时表现更差。本文系统综述了不同手术方式(单纯MPFLR及MPFLR联合各类骨性手术)对RTS水平的影响，并探讨了心理因素在RTS中的关键作用，旨在为临床优化治疗策略、制定个体化RTS方案提供参考。Lateral patellar dislocation (LPD) is a common knee sports injury among adolescents, with an increasing incidence year by year. Medial patellofemoral ligament reconstruction (MPFLR), as the mainstream surgical procedure for treating LPD, can achieve good clinical efficacy and significantly reduce the redislocation rate. However, there is still controversy regarding the level of return to sport (RTS) in patients, especially when combined with complex bony surgeries, where the performance is worse. This article systematically reviews the impact of different surgical methods (pure MPFLR and MPFLR combined with various bony surgeries) on the RTS level, and discusses the key role of psychological preparation in RTS, aiming to provide a reference for clinical optimization of treatment strategies and formulation of individualized RTS programs.
