Patellofemoral arthroplasty (PFA) is useful and effective option for treating patients with isolated patellofemoral osteoarthritis. The concept of functional positioning (FP) in PFA focuses on resurfacing the trochlea and restoring normal patellar tracking, while keeping the joint anatomy and kinematics. Even though the patellar liner cannot yet be placed with robotic assistance, robotic tools still help surgeons manage and optimize patellar tracking during surgery. This surgical technique highlights how the image-based robotic system assists the surgeon in improving patellar positioning and patellar tracking during a PFA. This technique could contribute to reduce complications, although its actual benefits remain to be validated. It may help prevent patellar instability through direct tracking assessment and reduce fracture risk by preserving more patellar bone. Accurate placement of the patellar button and evaluation of anterior offset might alleviate anterior knee pain. A tailored resection could also help protect the patellar vascular supply. Image-based planning may assist in avoiding malpositioning, potentially leading to fewer revisions.
髌股关节置换术（PFA）是治疗孤立性髌股关节骨关节炎患者的一种有用且有效的选择。PFA中的功能定位（FP）概念侧重于对滑车进行表面置换并恢复正常的髌骨轨迹，同时保持关节解剖结构和运动学。尽管目前还不能在机器人辅助下放置髌骨衬垫，但机器人工具仍有助于外科医生在手术过程中管理和优化髌骨轨迹。这种手术技术突出了基于图像的机器人系统如何在PFA手术中协助外科医生改善髌骨定位和髌骨轨迹。尽管其实际益处仍有待验证，但该技术可能有助于减少并发症。它可能通过直接跟踪评估来预防髌骨不稳定，并通过保留更多的髌骨骨质来降低骨折风险。准确放置髌骨纽扣和评估前侧偏移可能会减轻膝关节前部疼痛。量身定制的切除术也有助于保护髌骨的血供。基于图像的规划可能有助于避免位置不当，从而可能减少翻修手术的次数。
