Abstract
Objective: To evaluate the short-term results and complications of unicondylar knee prosthesis in obese patients with medial compartment arthrosis.
 
 Method: Unicondylar knee prosthesis was applied to 41 patients (36 females, 5 males; average age 56 years) with BMI >35 for the treatment of medial compartment arthrosis. Cementless Oxford phase 3 prosthesis was applied to all patients. Joint range of motion before and after surgery, VAS, OKS, and the KSS part 1 and part 2 scores of the patients were examined.
 
 Results: Flexion was measured as mean 115° (range, 90°- 135°) preoperatively, and 120° (range, 90° - 130°) postoperatively, extension as mean 0° (range, -10°- 0°) preoperatively and 0° (range,-15° - 0°) postoperatively, with no significant difference determined. The KSS Part 1 score was mean 58 (range, 36-82) preoperatively, and 85 (range, 57 - 96) postoperatively (p
