Factors Affecting Delayed Return to Sports after Lateral Meniscus Repair

Abstract

Objective: Delayed return to sports is sometimes observed after meniscal repair; however, the factors contributing to this delay remain unclear. This study aimed to identify factors associated with delayed return to sports after lateral meniscus (LM) repair.

Methods: This study included 33 patients (33 knees) who underwent LM repair using the inside-out technique and were followed for at least 6 months postoperatively. Patients were divided into two groups: those who returned to sports within 6 months (Group G) and those who returned after 7 months (Group P). Patient characteristics and postoperative functional outcomes were compared between the groups. An unpaired t-test was used for group comparisons.

Results: Compared with Group G, Group P demonstrated significantly reduced knee extension range of motion at 1 and 2 months postoperatively, as well as lower knee extension muscle strength at 3 months postoperatively.

Discussion: Early recovery of knee extension range of motion and knee extensor muscle strength may be important factors influencing the timing of return to sports after LM repair.
