“…The PMC is an additional stabilizer, providing one-third of the restraint to valgus stress when the knee is in extension. After isolated MCL injury, the POL acts as an important secondary stabilizer for rotation and valgus stress (14,(19)(20)(21)24,(26)(27)(28).…”

The posteromedial corner of the knee (PMC) is an important anatomic structure that is easily seen but often overlooked on magnetic resonance (MR) images. Whereas the posterolateral corner has been referred to as the "dark side of the knee" by some authors owing to widespread lack of knowledge of its complex anatomy, even less is written about the PMC; yet it is as important as the posterolateral corner in multiligament injuries of the knee. The PMC lies between the posterior margin of the longitudinal fibers of the superficial medial collateral ligament (MCL) and the medial border of the posterior cruciate ligament (PCL). The anatomy of the PMC can be complex and the literature describing it can be confusing, at times oversimplifying it and at other times adding unnecessary complexity. Its most important structures, however, can be described more simply as five major components, and can be better shown with illustrations that emphasize the anatomic distinctions. Injuries to the PMC are important to recognize, as disruption of the supporting structures can cause anteromedial rotational instability (AMRI). Isolated PMC injuries are rare; most occur in conjunction with injuries to other important stabilizing knee structures such as the anterior cruciate ligament (ACL) and PCL. Unrecognized and unaddressed injury of the PMC is one of the causes of ACL and PCL graft failures. Recognition of PMC injuries is critical, as the diagnosis will often change or require surgical management.

Resumo Objetivo Descrever todas as estruturas ligamentares, capsulares, tendinosas e marcos ósseos da região medial do joelho, assim como uma nova estrutura ligamentar identificada em uma série de dissecções anatômicas de espécimes cadavéricos. Métodos Vinte joelhos de cadáveres foram dissecados para estudar o compartimento medial. As principais estruturas dessa região foram identificadas durante a dissecção. A morfologia das estruturas e sua relação com parâmetros anatômicos conhecidos foram determinados tanto de forma qualitativa quanto de forma quantitativa. Os dados coletados foram analisados e interpretados por meio de estatística descritiva. Resultados Na dissecção de todos os espécimes, foram identificadas todas as estruturas ligamentares já descritas anteriormente no estudo anatômico da porção medial do joelho, e foram realizadas medidas objetivas que podem auxiliar como parâmetros para a reconstrução ligamentar cirúrgica. Foram observados e descritos, ainda, ao se desprender o ligamento colateral medial superficial, uma proeminência óssea imediatamente distal à sua inserção tibial proximal, uma bursa abaixo do ligamento, na qual o mesmo não se mostrava inserido, assim como uma estrutura ligamentar localizada extracapsularmente e com origem na face anterior do epicôndilo medial, seguindo obliquamente em direção à tíbia, aos quais foram dados os nomes, respectivamente, de tubérculo interinsercional, bursa interinsercional e ligamento oblíquo anterior. Conclusão Além da descrição e medida das estruturas e parâmetros já existentes no estudo anatômico da porção medial do joelho, foi possível a descrição de três novas estruturas: o tubérculo interinsercional a bursa interinsercional e o ligamento oblíquo anterior, ainda não descritos na literatura. Essas estruturas foram encontradas em todas as dissecções realizadas.

“…Conservative treatment may cause knee function limitation and accelerate the development of osteoarthritis 15 . Previous clinical studies have found that only repairing MCL without repairing POL cannot completely restore the static stability of the knee joint 2,16 , since, with a separate MCL damage, POL has become an important stable structure for controlling the rotation and valgus stress in the knee 5,17,18 .…”

Objective To evaluate the clinical effect of the one‐stage repair of a posterior oblique ligament avulsion fracture combined with a medial collateral ligament injury. Methods This study was a retrospective trial. From February 2007 to May 2017, five patients with posterior oblique ligament avulsion fracture combined with medial collateral ligament injury were included in this study. The patients were aged 37–58 years old with a mean of 45.2 years. All patients underwent the primary repair of a posterior oblique ligament avulsion fracture and medial collateral ligament injury. The main observational index included Lysholm score, International Knee Documentation Committee (IKDC) score, Visual Analogue Scale (VAS) score, and range of motion (ROM). Results The results showed that the average time of follow‐up was 53.6 months (range, 20–86 months). When compared to preoperative scores, the preoperative Lysholm score was significantly increased (47.8 ± 5.1 vs 95.0 ± 3.7, P < 0.05), the IKDC score was significantly increased (51.2 ± 5.6 vs 88.6 ± 4.2, P < 0.05), the VAS score was significantly decreased (7.0 ± 0.7 vs 0.4 ± 0.5, P < 0.05), and the ROM was significantly increased (91.6° ± 8.4° vs 129.9° ± 4.4°, P < 0.05). Conclusion Our study found that with the combination of the one‐stage repair of a posterior oblique ligament (POL) avulsion fracture and medial collateral ligament injury, the patient's postoperative function recovered well, their pain was relieved, and their knee joint stability was reliable.

An anatomical three-dimensional study of the posteromedial corner of the knee

Abstract: Posteromedial corner ligament structures are quite complex and are not always clearly described in the literature. Three-dimensional images of these structures can help better understanding its anatomy.
