Unicompartmental Knee Replacement
Unicompartmental or partial knee replacement replaces the worn part of the knee whilst retaining the healthy part of the knee.
This is not a new concept but there has been resurgence in popularity recently. Better instruments allow for better tissue balancing and also allow for minimally invasive surgery.
Most commonly the medial compartment of the knee is replaced though occasionally in patients with disabling lateral compartment or patellofemoral (knee cap) arthritis this procedure would be suitable.
