Abstract
Background: We undertook to study the dependency between the obesity and results of total knee replacement. Material and Methods: Our research involved 73 patients after total knee replacement. The clinical and functional outcomes of 39 obese patients with BMI > 30 were compared with the results of a matched group of 34 patients with BMI < 30. The Knee Society Score and pain scale (VAS) were used to assess function of patient andfiinction of operated knee. The patients %we examined twice: at baseline before the surgery and 6 months after surgery, as follow-up. Results: There was a statistically significant increase of KSS scores after surgery in all patients. Av-erage increase was 79 scores in obese patients and 90 scores in nonobese patients. There writ a sta-tistically significant difference between obese and nonobese patients in postoperative KSS score. There nos significant increase of Knee Score and Functional Score in both groups of patients. Average in-crease of Knee Score nos 51,6 points in obese and 53,2 points in nonobese patients. The Functional Score rose 27,5 points in obese and 35,0 points in nonobese. There nos no statistical difference in obese and nonobese between the improvement in scores. Average improvement in pain feeling (VAS) urns similar in both groups. Conclusions: There wan V statistically significant correlation between obesity and results of total knee replacement.
