Background: Use of mini-subvastus   approach for  total  knee  arthroplasty  (TKA )  in  obese  patients  is  still  debated . 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  approach  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: 97 obese patients (109 knees) 81 females + 16 males with mean age 64 years underwent TKA by mini-subvastus approach between January 2006 to July 2007. 16 patients (18 knees) were morbidly obese. Out of the total number of patients, 08 were lost in follow up and 01 died because of unrelated causes. Out of these 09 patients, two were operated for bilateral TKR. Thus, we have a midterm follow up results of 98 knees in 88 patients. Knee society and functional scores were used for patient evaluation and compared to their pre-operative and earlier follow up scores.Results: At our latest follow-up of 96 months the Knee Society Score and functional scores were 84(range 64-90) and 58(range 45-75) respectively. One morbidly obese lady had aseptic loosening of tibial component at 42 months which needed a revision.Conclusion: Our mid-term results show that the mini-subvastus approach can be  considered  for TKA in obese and morbidly obese patient population with outcomes comparable to standard surgical approach.Keywords:  Mini-subvastus approach, Total knee arthroplasty ,Obesity

AbstractOut of concern for the increased risk of complications with morbid obesity, institutional body mass index (BMI) cutoffs for total knee arthroplasty (TKA) have become commonplace. We sought to answer the questions: what percentage of morbidly obese patients with knee osteoarthritis who present to an arthroplasty clinic will, within 2 years, undergo TKA at (1) a BMI less than 40 kg/m2 or (2) at a BMI greater than 40 kg/m2? Of those who do not undergo surgery, (3) what percentage lose enough weight to become TKA-eligible, and (4) what percentage do not? We performed an observational study of 288 patients, of which 256 had complete follow-up. Institutional electronic medical record review and patient follow-up by telephone were conducted to determine which patients underwent surgery, and at what BMI. For those that did not undergo TKA, BMI was examined to see if the patient ever lost enough weight to become TKA eligible. Twelve of 256 patients (4.7%) underwent TKA at a BMI less than 40 kg/m2, 64 patients (25%) underwent TKA at a BMI greater than 40 kg/m2, and 7 patients (2.7%) underwent surgery at an outside hospital. The average BMI at the time of surgery was 42.3 kg/m2. Thirty-seven of 256 patients (14.4%) lost enough weight to become TKA-eligible within 2 years of the initial visit but did not undergo surgery, while 136 patients (53.1%) neither underwent TKA nor became eligible. Strict enforcement of a BMI cutoff for TKA is variable among surgeons. In the absence of weight loss protocols, 19.1% of morbidly obese patients may be expected to reach the sub-40 kg/m2 BMI milestone.

Abstract Background Residual varus after total knee arthroplasty (TKA) can affect functional outcomes and prosthetic survival, which may worsen in the presence of obesity. However, no studies were found to compare the outcomes of obese patients involving postoperative residual mild varus or neutral. The aim of this study was to compare outcomes for knees of obese patients with neutral or mild varus after TKA. Methods We retrospectively reviewed 188 consecutive obese patients (body mass index ≥ 30 kg/m2) at our hospital who underwent TKA due to varus knee osteoarthritis from January 2010 to December 2015. The mechanical hip-knee-ankle axis angle was measured in all patients pre- and postoperatively. Prosthesis survival and knee function were retrospectively assessed based on the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, Knee Society Knee Score (KS-KS), Knee Society Function Score (KS-FS), Forgotten Joint Score (FJS), and range of motion (ROM). Results Of the 156 knees in 132 obese patients who completed follow-up for a mean of 8.32 ± 1.47 years, 97 knees were corrected from varus to neutral and 54 knees were kept in mild residual varus. Knees with mild varus showed significantly better WOMAC and FJS scores. The two types of knees did not differ significantly in KS-KS, KS-FS or ROM. Although one patient with a neutral knee had to undergo revision surgery, there was no significant difference between two groups.Conclusions For obese patients with osteoarthritis, preservation of residual varus alignment after TKA can improve functional outcomes without compromising prosthesis survival.
