Abstract

Preservation of native knee anatomy may confer improved patient satisfaction, as suggested by patient satisfaction scores in unicondylar versus total knee replacement. Bicompartmental knee replacement (BKR) implants similarly promote native tissue preservation. We retrospectively reviewed 42 consecutive patients who underwent BKR from 2006 to 2007. Outcome measures were evaluated. At an average follow-up of 103 months (range 87–110), 34/42 (81%) of implants survived. Among the retained implants, the Knee Society Score (KSS) grade was excellent in 26/34 (76.5%), good in 5/34 (14.7%), fair in 3/34 (8.8%), and poor in 0/34 (0%) of cases. Midterm results of BKR demonstrated 81% survival and 76% with excellent KSS grading. Despite a 20% revision rate at the short-term follow-up, the retained implants functioned well at the midterm follow-up.
