Abstract
Background: Use of mini-subvastus approach for to-tal knee arthroplasty (TKA ) in obese patients is still de-bated. We had hypothesized in our study published in July 2010 , that obesity should not be considered as a problem for patients undergoing a TKA with the mini-subvastus ap-proach as the anatomy of the quadriceps in the obese and the non-obese patient population is the same. We present a mid-term follow-up study of the same set of patients with an average follow up of 96 months.
Materials and Methods: There were 97 obese patients (109 knees), 81 females + 16 males with a mean age of 64 years that underwent TKA by mini-subvastus approach be-tween January 2006 to July 2007. A total of 16 patients (18 knees) were morbidly obese. Out of the total number of pa-tients, 8 were lost in follow up and one died because of un-related causes. Out of these 9 patients, two were operated for bilateral TKR. Thus, we have a midterm follow up re-sults of 98 knees in 88 patients. Knee society and function-al scores were used for patient evaluation and compared to their pre-operative and earlier follow up scores.
