A pretibial cyst after anterior cruciate ligament (ACL) reconstruction is a rare complication. This report presents a case of a subcutaneous pretibial ganglion with direct communication to the tibial tunnel, after ACL reconstruction with a quadrupled hamstrings tendon autograft, in a 26-year-old Caucasian male.

Total knee arthroplasty in severe valgus deformity: interest of combining a lateral approach with a tibial tubercle osteotomy.

The purpose of this study is to evaluate the results of TKA in grade II and III valgus knee deformities (Ranawat classification), focusing on axis correction, by using a lateral parapatellar capsulotomy combined with tibial tubercle osteotomy.
