Patellofemoral arthroplasty (PFA) has emerged as an alternative bone-preserving surgical option for treating isolated symptomatic patellofemoral osteoarthritis that better replicates the natural knee kinematics compared with total knee arthroplasty. Achieving successful outcomes in PFA relies on meticulous patient selection, proper surgical technique, and appropriate implant choice and placement. Recent advancements in inlay trochlea implants, allowing for customized and anatomic joint line reconstruction with less bone resection, have demonstrated significant improvements in functional outcome scores and pain relief. This Technical Note aims to provide insights into the surgical technique of PFA with inlay implants, highlighting key considerations and potential challenges. It also assists surgeons in making informed decisions regarding the choice between standard and dysplastic inlay implants, while suggesting concurrent procedures to optimize tracking and overall outcomes.
髌股关节置换术（PFA）已成为治疗孤立性症状性髌股关节骨关节炎的一种保留骨的手术选择，与全膝关节置换术相比，它能更好地复制自然膝关节的运动学。PFA取得成功的结果依赖于精心的患者选择、恰当的手术技术以及合适的植入物选择和放置。镶嵌式滑车植入物的最新进展，能够在较少骨切除的情况下进行定制化和解剖学关节线重建，已在功能结果评分和疼痛缓解方面显示出显著改善。本技术说明旨在深入探讨使用镶嵌式植入物的PFA手术技术，突出关键考虑因素和潜在挑战。它还帮助外科医生在标准镶嵌式植入物和发育异常镶嵌式植入物之间做出明智的选择，同时建议采用同期手术来优化轨迹和整体结果。
