编辑评论：警惕残留半月板皱缩——盘状外侧半月板成形术后保留更多并非更好
简介
针对盘状外侧半月板成形术后的残余半月板宽度，该述评结合连续MRI分析指出：术后体部宽度>13 mm者更易发生半月板挛缩、并发症率更高，而9～13 mm的“功能目标区间”更接近正常外侧半月板。作者据此提出术式目标已从“尽量少切”转向“精准切除”，但本文属述评而非原始研究。
英文摘要
Recent literature has shown optimal residual meniscal width after saucerization and repair of discoid lateral meniscus. Using serial magnetic resonance imaging analysis, the authors defined the appropriate postoperative meniscal morphology. Notably, larger postoperative midbody widths (>13 mm) were associated with shrinkage and higher complication rates, challenging the idea that greater tissue preservation is beneficial. Instead, the study identifies a "functional target zone" of 9 to 13 mm, aligning closely with the native lateral meniscus. Despite convergence in meniscal width over time, increased complications in initially oversized resections suggest no long-term advantage to under-resection. The findings also highlight the role of postoperative remodeling, meniscal extrusion, and patient activity levels in influencing outcomes. Overall, the focus has shifted from under-resection to optimal resection, providing clinically relevant guidance for improving outcomes in discoid lateral meniscus treatment.
