Fresh meniscal allograft transplantation and autologous ACL/PCL reconstruction in a patient with complex knee trauma following knee dislocation – a case report

Instability of the knee joint, particularly in combination with the loss of one meniscus, regularly leads to the early development of arthritis. This paper describes the case of a 19‐year‐old male with ruptures of the anterior (ACL) and posterior cruciate ligament (PCL) along with the loss of the medial meniscus due to knee dislocation. Combined, time‐delayed reconstruction of both the ACL and PCL and the allogenic fresh meniscal transplantation of the medial meniscus without bone plugs were performed. The control arthroscopy performed 6 months post‐transplantation revealed good vitality and integration of the grafts as assessed both macroscopically and histologically. A small portion of the posterior horn had to be refixated, and the anterior horn was atrophic. At 24 months after trauma and 13 months following meniscal transplantation, the patient achieved a Lysholm score of 88 points and clinical examination indicated a stable knee. Fresh meniscal allograft transplantation, in combination with autologous ACL and PCL reconstruction, constitutes – in specialized centers – an alternative treatment option for complex trauma of the knee joint with loss of a meniscus.
