- Abstract
Objective: To evaluate the short-term results and complications of unicondylar knee prosthesis in obese patients with medial compartment arthrosis. Methods: 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° ( 90°- 135°) preoperatively, and 120° ( 90° - 130°) postoperatively, extension as mean 0° ( -10°- 0°) preoperatively and 0° (-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 <0.001). The KSS part 2 score was 50 (range, 35- 80) preoperatively and 90 (range, 51 -100) postoperatively (p <0.001). The Oxford score was mean 16 (range, 9 - 30) preoperatively, and 38 (range, 20 - 44) postoperatively (p <0.001). The differences between these scores were determined to be statistically significant. Complications developed in a total of 3 (%7,3) patients as periprosthetic joint infection in 1 patient (2.4%) and insert dislocation in 2 patients (4.9%). Conclusions: The study findings demonstrated that the application of unicondylar knee prosthesis is effective and successful in obese patients treated for medial gonarthrosis. There is a need for further long-term studies to confirm these results.
