Iatrogenic medial patellar instability is a specific condition that frequently causes incapacitating anterior knee pain, severe disability, and serious psychological problems. The diagnosis should be suspected in a patient who has undergone previous patellar realignment surgery that has made the pain worse. The diagnosis can be established by physical examination and simple therapeutic tests (e.g., "reverse" McConnell taping) and confirmed by imaging techniques. This iatrogenic condition should no longer exist and could almost be eliminated by avoiding over-release of the lateral retinaculum.
医源性髌骨内侧不稳定是一种特殊情况，常导致使人丧失能力的前膝疼痛、严重残疾和严重的心理问题。对于曾接受过髌骨重新排列手术且术后疼痛加重的患者，应怀疑有此诊断。可通过体格检查和简单的治疗性试验（如“反向”麦康奈尔贴扎法）来确立诊断，并通过影像学技术加以证实。这种医源性情况不应再存在，通过避免过度松解外侧支持带几乎可以消除。
