Rehabilitation Strategies Following Isolated Meniscal Repair: A Systematic Review of Protocols and Outcomes

<b>Background:</b> Meniscal injuries are common athletic injuries, and isolated meniscal repair is a critical procedure for restoring knee function. However, rehabilitation protocols after meniscal repair remain controversial. This systematic review aimed to evaluate rehabilitation protocols to determine the best strategies for enhancing recovery following isolated meniscal repair. <b>Objectives:</b> Analyze current rehabilitation protocols following isolated meniscal repair, focusing on the efficacy of approaches in improving functional outcomes and reducing recovery time. This study also aims to identify gaps in the existing literature and provide recommendations for future studies. <b>Data sources:</b> Search was conducted using PubMed, Scopus, and Web of Science databases, covering studies published between May 2015 and May 2024. Inclusion criteria: Studies reporting on isolated meniscal repair with defined postoperative rehabilitation protocols and quantifiable outcome measures. Data extraction: Focused on patient demographics, meniscal tear types, repair techniques, and rehabilitation outcomes. The methodological quality of the included studies was assessed, and narrative synthesis was conducted. <b>Results:</b> The review included 13 studies with significant variability in rehabilitation protocols and outcomes. Early weight-bearing and range of motion exercises have been associated with improved recovery in some studies for stable meniscal tears. However, conservative approaches have better outcomes in patients with complex tears. The use of adjunctive therapies such as blood flow restriction training has demonstrated potential in enhancing muscle preservation and overall recovery. <b>Conclusions:</b> Rehabilitation protocols after meniscal repair surgery should be individualized. Although innovative protocols show promise, further research is needed to standardize rehabilitation approaches and optimize long-term outcomes.
