稳定性恢复，软骨受损？——重新审视ACL重建后的髌股关节结局

简介

本文回顾性分析了ACL重建术后髌股关节结局，指出尽管手术在恢复膝关节稳定性（如轴移试验阴性）方面取得显著成功，但髌股关节作为股四头肌力量转化为运动的关键结构，长期被忽视。临床医生应警惕ACL重建后髌股关节的潜在软骨损伤与功能影响，在追求稳定性的同时关注髌股关节的远期预后。

英文摘要

Over the last decades, we have built an empire around the anterior cruciate ligament (ACL). We measure stability in millimetres and celebrate isokinetic symmetry and congratulate ourselves when the pivot shift falls silent. For decades, this has defined success-a stable knee that no longer gives way. Yet, while we were perfecting the graft choice, the technique, the fixation and the biology of the graft, another story has been quietly unfolding. The patellofemoral joint-the true translator of quadriceps power into motion-is the forgotten joint of the ACL reconstruction era.
