Unicompartmental Knee Replacement

Abstract

The results of unicompartmental knee replacement in a series of 83 knees were reviewed for the period of 1970 to 1978; 30.1 percent achieved good or excellent results; 48.2 percent fair or poor results; 21.7 percent were failures. The vast majority of failures and poor results were due to technical errors. Only 9.6 percent of the nonoperated contralateral compartments required further surgery.
