A 69-year-old man presented with severe valgus deformity and pain related to progressive bilateral knee osteoarthritis. At admission, the patient could walk a maximum distance of 200 meters without any orthopaedic aids. The patient was scheduled for total knee arthroplasty (TKA) of his left knee. The left knee demonstrated a 5° extension deficit and maximum flexion of 90°. He underwent a medial approach TKA of the left knee using a rotating hinge prosthesis - Legion Hinge. After the operation, full extension and flexion of 129° were achieved, with stability throughout the entire range of motion (ROM). At discharge, he was walking with elbow crutches and was appointed for physiotherapy at a rehabilitation clinic. At the two-month follow-up control check-up, the patient presented with improved flexion to 135 degrees, better pain control and improved quality of life compared to the period preceding the operation.
