Oxford unicompartmental knee replacement: literature review.

Oxford unicompartmental knee replacement surgery (Biomet Orthopedics, Inc, Warsaw, Ind) provides excellent long-term results according to numerous published series, with 10-year survivorship ranging from 91% to 100% and 15- year survivorship of 93%. Few knee prostheses can rival these results. Most of these cohorts included patients with anteromedial- or medial-specific disease, although some cohorts included patients with lateral-specific disease. Also, most cohorts were performed in patients with a mean age of >60 years, with a wide range of ages including patients in their 30s to 90s. Almost all of the arthroplasties were performed in patients with osteoarthritis, and some were performed in patients with avascular necrosis.
