PCL reconstruction was a transtibial arthroscopic double-bundle reconstruction using Achilles tendon and tibialis anterior allograft tissue using mechanical graft tensioning, and the posterolateral reconstruction was a fibular head-based figure of eight reconstruction using semitendinosus allograft tissue combined with a posterolateral capsular shift procedure and peroneal nerve decompression and neurolysis [, Posterior cruciate ligament and posterolateral reconstruction of the knee. Posterior cruciate ligament injury: MR imaging diagnosis and patterns of injury. Treatments include both non-surgical and surgical options. Corin . In this mechanism, PCL is torn in the middle portion, and the posterior joint capsule may also be disrupted. It becomes thinner as it approaches the tibia, and it is partially embedded within the joint capsule. The posterior cruciate ligament (PCL) is a ligament within the knee. The typical appearance is that of a well-defined multilocular cystic mass within or adjacent to the posterior cruciate ligament 1.

Mean posterior tibial slope angle was around 7. . Even if PCL is damaged and its function impaired or lost, the knee instability upon weight-bearing is less commonly seen than in ACL tear, and patients may not be aware of any symptoms. The capsule is lined with synovium, which is convoluted and thus has a large floor area; within the larger knee, due to this fact, more quantity might be required to bathe all of the goal area. Clin Image Case Rep J. This tension mainly acts on AMB. MRI appearance of posterior cruciate ligament tears. Posterior cruciate ligament ganglion cysts are also referred to as 'posterior cruciate ligament cysts' or 'ganglia'1.
