Medial patellar subluxation is a poorly recognized clinical condition characterized by chronic anterior knee pain that is exacerbated with knee flexion. Additional symptoms include instability, limited knee motion, and pain with squatting and stair climbing. Full characterization of the patient's knee pain requires an accurate history and physical examination. Diagnosis is typically confirmed during diagnostic arthroscopy. When nonsurgical management (eg, physical rehabilitation, patella-stabilizing bracing) fails, surgery (eg, medial retinacular release, lateral retinacular imbrication, newer techniques to repair or reconstruct the lateral retinaculum/lateral patellofemoral ligament) can lead to good results. Further study is needed to confirm current understanding of medial patellar subluxation and to better define treatment options and prevention strategies.
髌骨内侧半脱位是一种临床认识不足的病症，其特征为慢性膝前疼痛，在膝关节屈曲时加重。其他症状包括膝关节不稳定、活动受限，以及下蹲和爬楼梯时疼痛。要全面了解患者的膝痛情况，需要准确的病史和体格检查。诊断通常在诊断性关节镜检查时得到证实。当非手术治疗（如物理康复、髌骨稳定支具）无效时，手术（如内侧支持带松解、外侧支持带叠瓦成形术、修复或重建外侧支持带/外侧髌股韧带的新技术）可能会取得良好效果。需要进一步研究以证实目前对髌骨内侧半脱位的认识，并更好地确定治疗方案和预防策略。
