髌股关节保留：软骨修复、减荷与并发症规避
简介
该文系统综述髌股关节软骨损伤的修复与卸载策略，强调明确病灶特征及识别软骨损伤的主要力学驱动因素，并总结当前及新兴的软骨修复技术。作者指出，持久疗效常需通过机械卸载和软组织平衡进行生物力学优化，以支持手术决策并提高髌股关节远期存活率。
英文摘要
Patellofemoral (PF) chondral lesions are a common source of knee pain and disability, typically arising from traumatic (instability/fracture) or degenerative (overload) etiologies. This review synthesizes contemporary evidence on PF joint preservation with an emphasis on avoiding complications. We highlight the importance of defining lesion characteristics and identifying the primary mechanical driver(s) of chondral injury. We then summarize current and emerging cartilage restoration options. Finally, we emphasize that durable outcomes often require concomitant biomechanical optimization through mechanical unloading and soft tissue balancing. Collectively, this review aims to support informed surgical decision-making and maximize long-term survival of the PF joint.
