Summary

A newly designed stable total knee prosthesis was made for the severely destructed knee. This prosthesis was named the Yoshino total knee prosthesis, and is a non-hinged type prosthesis consisting of a vitallium femoral component and a ultra-high molecular weight polyethylene tibial component. Clinical results of 127 Yoshino total knee arthroplasties showed the following characteristics: 1) good stability, and 2) good mobility. Stability was exceptionally good, and the results were the same as the hinged total knee prosthesis.

Zusammenfassung

Ein newer Typ der totalen Knieprothese wurde für den Ersatz des schwer beschädigten Knies hergestellt. Diese Prothese, zur Zeit „Yoshino-Total-Knie-Prothese” genannt, ist eine Art der achsellosen Prothesen mit dem Vitallium-Femoralkomponent und Polyethylen-Tibiakomponent von ultra-hohem Molekulargewicht. Unsere bisherige klinische Anwendung bei 127 Fällen zeigte folgende Resultate: 1) gute Stabilität und 2) gute Beweglichkeit des operierten Kniegelenks. Dabei muß betont werden, daß diese neuartige Knieprothese ganz stabil ist, wie die bisherigen Prothesen mit dem Achsel.
