We performed medial unicompartmental knee arthroplasties (UKA) using minimally invasive surgical technique (MIS) in 23 patients from 2002 to 2006. The MG Uni UKA system (13 knees), and Zimmer Uni UKA system (10 knees) were used in the procedure. Osteoarthritis (OA) was diagnosed in fifteen knees, and osteonecrosis (ON) of femoral condyle in 8 knees respectively. The patients mean age was 77.4 years (66-85), and the mean follow up period 16.9 months (6-50). The mean operation time was reduced from 116 min to 107 min since 2005. The bleeding was minimal. Mean preoperative hemoglobin dropped from 12.5 g/dl to 11.7 g/dl the day after surgical procedure. Further more no blood transfusion was required. The mean preoperative range of motion was 135 and 134 degrees at the latest review. The mean JOA score improved from 52 to 89 points. Mean gait stability was achieved at day 11.2 (4-25). In conclusion, rapid recovery and minimal invasiveness makes this procedure (MIS-UKA) an excellent therapeutic option for older patient suffering from OA and ON.
