Abstract
Aim of the study was to evaluate the recovery and short term results of simultaneous bilateral unicompartmental knee replacement in front of unilateral procedure.
Materials and methods: At the “Istituto Ortopedico Galeazzi”, in Milan, we performed 244 UKR in a 12 months period. Forty were sequential bilateral procedure. We compared two groups of patients: one bilateral sequential procedure (BPS), the other unilateral procedure (UP). Student t test has been used for statistical analysis.
Results: Blood transfusion: BSP 8 cases, and UP 5 cases. 90° active flexion: BSP 4,7 (2–6) days, and UP 3,5 (1–6) days. Stairs climbing: BSP 5,6 (4–8) days, and UP 4,9 (4–9) days. Hospital stay: BSP 12,4 (10–17) days, and UP 11,4 (5–19) days; p=0,045. Complications during the first month after surgery: BSP none, and UP 3 (1 wound redness, 2 urinary infection). From 6 to 18 months, KSS and function: BSP 53 (28–80) points, 61 (20–100) points; UP 51 (25–85) points, 66 (20–100) points; p=0,325 e p=0,133. Oxford self assessment were: BPS 26,57 and UP 23,54. No statistically significant differences were among groups.
Conclusions: This study shows bilateral procedure is safe, and allows recovery comparable to single knee procedure. Bilateral sequential unicompartmental procedure should be considered for bilateral arthritis of the knee.
