Knee central pivot bicruciate avulsion and proximal anterior cruciate ligament tear primary repair: A rare case report

The knee is susceptible to complex injuries after trauma including fractures, multiple ligamentous lesions and avulsions due to its numerous tendinous, ligamentous and meniscal attachments. The authors describe a rare case of a 33-year-old male patient with a trauma of the right knee following a motorcycle accident, who sustained avulsion of both femoral and tibial insertion sites of anterior cruciate ligament and avulsion of tibial insertion of posterior cruciate ligament without other associated ligament lesions. The patient underwent a clinical-anamnestic and imaging evaluation to identify the lesions. Knee X-rays showed a tibial avulsion of anterior and posterior cruciate ligaments confirmed by CT scan, classified as type 3b according to Meyers and Mckeever. The authors decided for a surgical management: reduction and internal fixation of anterior and posterior cruciate ligament tibial bone fragments and repair of anterior cruciate ligament femoral avulsion using suture pull-out technique. The patient has been followed, with accurate clinical and radiological follow up controls, for 12 months and showed excellent clinical outcomes using Tegner-Lysholm Knee Score (95/100 points) and good range of motion and knee stability.
