Zusammenfassung
Medial unicompartmental knee replacement (UKR) preserves all the undamaged structures of the joint, in particular the cruciate ligaments, and can therefore restore knee function nearly to normal. After UKR the range of movement is better than after TKR, the knee feels more natural and pain relief is as good or better [1-3]. In terms of morbidityy, operative blood loss is less and transfusion unnecessary; complications are less fre-quent and less serious and recovery is more rapi. However, UKR has the disadvantage that the medium and long-term revision rates are generally higher than for TKR. The reasons for this include:
-
The high polyethylene wear rate of thin tibial components subjected to incongruous loading.
-
Imprecise (and inappropriate) limits for patient selection.
-
Lack of instruments to enable intraoperative restoration of the retained ligaments to isometric function
