A 73-year-old female patient underwent total knee arthroplasty for arthrosis. After surgery, recurvatum instability over 55 degrees occurred. Two years later, primary endoprosthesis was removed and a revision endoprosthesis implanted. However, complete deformity occurred again. Two years later, the thickest revision polyethylene tibial implant was implanted on the same endoprosthesis. In spite of using knee orthosis, recurvatum deformity returned. Seven months later, new revision rotating hinge prosthesis was implanted. This procedure seems to have solved the problem. The knee deformity in this specific case was larger than the deformity in cases reported so far, and it was solved after three surgical procedures. Rotating hinge prosthesis seems to be the method of choice for immediate repair of recurvatum instability after total knee arthroplasty.
