title: [Total knee replacement using the Walldius hinge joint (author's transl)].
abstract: 45 Walldius knee joints have been reevaluated an average of 3 years after implantation. 75% were considered good to excellent when compared with the preoperative situation. Most failures were due to infection (11%). The end result depends largely on the condition of adjacent joints which frequently prevent a major improvement in walking ability inspite of a successful implantation of a Walldius prosthesis. The Walldius hinge joint was prefered over other designs because of its large weight-bearing flanges. It can absorb static forces better without sinking into the tibial or femoral shafts. Inspite of a resection of 3 cm, a fusion is still possible if necessary. The use of cement is emphasised to prevent migration of the prosthesis and fracture of the shafts. Inspite of a high complication rate the prosthestic replacement of a severely destroyed knee joint by a Walldius hinge is a promising procedure.
