Aim: This study aimed to determine the short-term clinical and radiologic results of medial unicondylar knee arthroplasty (UKA). Methods: We retrospectively evaluated hospital records of eight patients who have undergone Oxford phase-3 medial UKA between 2011 and 2013. We included seven patients (two males and five females) in the study. The mean age of the patients was 63 years and the mean follow-up period was 17 months. The patients underwent UKA with the Oxford phase 3 cemented mobile insert unicondylar prosthesis using minimally invasive surgery technique. The patients were assessed preoperatively, postoperatively and at final controls according to the Knee Society’s clinical and Functional Scoring system (KSS). The mean anatomic tibiofemoral angle was measured preoperatively and postoperatively and any complication was recorded. Results: The mean knee score according to the KSS was 37.50 preoperatively and was 90.75 at the final follow-up; the mean function score according to the KSS was 31.88 preoperatively and was 93.12 at the final follow-up. The mean anatomic tibiofemoral angle was improved from 4.37 degree varus to 4.75 degree valgus. There was no complication in any patient except one with superficial infection who was treated by simply antibiotic treatment. Conclusion: UKA is a favorable surgical technique for appropriately selected patients with medial unicompartmental knee osteoarthritis. (The Me­di­cal Bul­le­tin of Ha­se­ki 2014; 52: 191-4)
