Unicompartmental knee arthroplasty for single compartment disease. Clinical experience with an average four-year follow-up study.
Unicompartmental knee arthroplasty using the Marmor modular knee prosthesis or, later, the Richards Modular II prosthesis in a series of 72 knees (60 patients) is reviewed, with an average follow-up period of four years (minimum, 2 years). Pain relief was rated as excellent in 90% of the knees. The average range of motion was improved after operation. No deep infections were encountered. Only one knee in the series has required further surgery, for patellofemoral disease.
