Research Progress on Return to Sport After Surgery for Lateral Patellar Dislocation

Lateral patellar dislocation (LPD) is a common knee joint sports injury in adolescents, with an incidence increasing year by year. Medial patellofemoral ligament reconstruction (MPFLR), as the mainstream surgical method for treating LPD, achieves favorable clinical efficacy and significantly reduces the redislocation rate. However, controversies remain regarding patients' return to sport (RTS) level, especially when combined with complex bony surgeries, where RTS outcomes are poorer. This review systematically evaluates the impact of different surgical strategies (isolated MPFLR and MPFLR combined with various bony surgeries) on RTS levels and explores the key role of psychological factors in RTS. It aims to provide references for optimizing clinical treatment strategies and formulating individualized RTS protocols.
