Abstract
Introduction: Primary total knee replacement (TKR) is one of the most commonly performed orthopedic procedures. With the increasing prevalence of obesity and advancing age of the population, it is imperative to know whether the obese patients have inferior or equivalent outcomes as opposed to non-obese patients. Hence, this study was planned to learn the functional and radiological outcomes of TKR surgery in obese and non-obese patients.
Materials and Methods: This prospective observational study included 64 adult patients 32 obese (body mass index [BMI] >30) and 32 non-obese (BMI <30) operated for TKR surgery. Functional outcome was assessed by patient-reported outcome measures using Oxford knee score (OKS) and short form-12 (SF-12) quality of life questionnaires at 6 weeks postoperatively. Radiological outcomes were assessed using pre- and post-operative radiograph and bilateral lower limb scanogram.
Results: On comparing the mean hospital stay, that of obese patients was 8.16 days and that of non-obese patients was 6.72 days (significant). The OKS improved from 14.19 to 37.44 in the obese group and from 14.75 to 38.59 in non-obese group. In obese patients, the physical component of SF-12 score improved from 23.92 to 53.6 postoperatively, and that in non-obese patients went from 27.29 to 53.08. The mean mental component of SF-12 score improved from 48.59 to 56.37 postoperatively in obese patients, in non-obese patients it improved from 53.02 to 57.94 postoperatively (significant). Hip-knee-ankle axis in obese patients on the right side improved from 171.18° to 176.82° (significant), left side from 171.31° to 176.71° whereas in non-obese patients right side from 171.89° to 176.94°, left side from 171.82° to 176.66°. Comorbidities were seen more in obese patients (diabetes 21 of 32 cases, hypertension 17 of 32 cases) than in non-obese patients (diabetes 12 of 32 cases, hypertension 16 of 32 cases). Superficial surgical site infection (SSI) in about 3 of 32 obese patients, whereas no SSI was found in non-obese patients.
Conclusion: The present study assesses the patients’ perception of their outcomes which are important in clinical decision-making. There was no significant difference found in patient perceived parameters, functional and radiological outcomes at end of 6 months following TKR surgery in both obese and non-obese patients.
