Staged reconstruction of bicruciate and posterolateral corner injury after low-energy knee dislocation: A case report

Knee dislocation is a rare but severe injury frequently associated with multiligament damage and possible vascular compromise. We report the case of a 42-year-old male with no previous medical history who sustained a low-energy knee dislocation following a trampoline accident. Angio-CT ruled out vascular injury. MRI demonstrated complete rupture of both cruciate ligaments and posterolateral corner injury. A staged surgical strategy was adopted: PCL and PLC reconstruction

at 4 weeks, followed by ACL reconstruction 9 months later. At 15-month follow-up, the patient showed full stability, absence of pain, and progressive return to sports. This case supports staged reconstruction as a safe and effective strategy in multiligament knee injuries.
