From: Results of total knee arthroplasty for painless, stiff knees
A 60-year-old female patient who had a history of arthrodesis due to severe trauma of the right knee at the age of 50 years, had an ankylosed knee in the 10º flexion position. The right knee was operated on with a valgus-varus constrained (VVC) type (Nexgen LCCK) prosthesis. A tibial tuberosity avulsion fracture occurred in the operation, which was fixed using the tension-band wiring technique. The postoperative arc motion was improved from 0 to 65 (range; 15–80º) with 15º of extension lag. In the 16-year follow-up, polyethylene wear and a fracture of the medial femoral condyle were noticed. A revision was performed with the same type of implant and an internal fixation of the fracture fragment
