The medial patellar retinaculum (MPR) and the lateral patellar retinaculum (LPR) are vital structures for the stability of the patella. Failure to identify or treat injury to the patellar retinaculum is associated with recurrent patellar instability and contributes to significant morbidity. High-resolution magnetic resonance imaging (MRI) readily depicts the detailed anatomy of various components (layers) of the retinacula. In this review article, we discuss normal anatomy, important landmarks, common injury patterns, and other pathologies encountered in patellar retinacula. High field strength MRI is an excellent noninvasive tool for evaluation of patellar retinaculum anatomy and pathology. This article will help the reader become familiar with normal imaging findings and the most commonly occurring injuries/pathologies in MPR and LPR.
髌内支持带（MPR）和髌外支持带（LPR）是维持髌骨稳定性的重要结构。未能识别或治疗髌支持带损伤与复发性髌骨不稳定有关，并导致显著的发病率。高分辨率磁共振成像（MRI）可清晰显示髌支持带各组成部分（层）的详细解剖结构。在这篇综述文章中，我们讨论了髌支持带的正常解剖结构、重要的解剖标志、常见的损伤模式以及其他病理改变。高磁场强度 MRI 是评估髌支持带解剖结构和病理改变的极好的无创工具。本文将帮助读者熟悉 MPR 和 LPR 的正常影像学表现以及最常见的损伤/病变。
