title: Primary rotating-hinge total knee arthroplasty: good outcomes at mid-term follow-up.
abstract: We evaluated the clinical and radiologic outcomes of primary knee replacements using a rotating-hinge knee prosthesis in 12 knees with a minimum follow-up of 10 years. Indications for the operation included gross joint destruction, significant axial deformities and contracture with a dysfunctional medial collateral ligament in all cases. The patients' WOMAC and Knee Society scores improved, and the use of mobility aids decreased. No loosening of implants was observed. Nonprogressive radiolucent lines were identified around three tibial components. Three patients required marginal wound excision with resuturing and thereafter healed uneventfully. With significant improvement in function, pain and range of motion, the rotating-hinge knee prosthesis can be used as a salvage device in patients with medial collateral ligament deficiency, contracture, and gross joint destruction.
