Uni-compartmental knee replacement (UKR) is a partial knee replacement. This technique is indicated when only a small area of your knee is deteriorated. Partial knee replacement surgery is very attractive as it is bone-preserving (ease for potential further revision surgery), ligament preserving (for the best functional outcome), very safe (lowest rate of infection and other peri-operative complications, less blood loss), and with a very fast postoperative recovery. Patients are usually on their feet walking within few hours of the surgery and stay in a hospital for 1 to 3 days.
While partial knee replacement surgery has been shown to be a very safe and efficient option to treat focal osteoarthritis, it carries a greater risk of revision surgery compared to a primary total knee replacement. This is because partial knee replacement procedures are easy to be revised and surgeons do not hesitate to convert a moderately disappointing partial knee replacement to a total knee replacement. This increased revision rate used to be considered as a drawback, however, it reflects, in fact, a real strength of partial knee replacement surgery which is to be easily convertible to a total knee replacement.
Partial knee replacement surgery is only appropriate where the arthritis is isolated to one compartment of the knee. If you are eligible for a partial knee replacement, Charles will always offer you the choice between a partial and total knee replacement.
