Evaluation of effects of BMI on Functional Recovery Following Total Knee Arthroplasty Surgery

Dr. Anurag Chandrakar, Dr. Pratik Kawde

Abstract :

<p>&nbsp;Background: Obesity is a well known risk factor for complications following total knee arthroplasty, various data is</p> <div>available on the impact of the degree of obesity on patient-reported outcomes following total knee arthroplasty.</div> <div>In our study we tried to determine the extent to which obesity level affects the recovery as well as patient-reported pain, function, and</div> <div>satisfaction with after total knee arthroplasty surgery.</div> <div>Methods: We followed a cohort of patients who underwent total knee arthroplasty at our medical centre. Patients included were +40 years</div> <div>of age with a primary diagnosis of osteoarthritis. Patients were classi􀃶ed into 5 groups according to the World Health Organization</div> <div>classi􀃶cation of body mass index (BMI). Assessment was done between BMI group and pain and function over the time intervals of 0 to 3, 3</div> <div>to 6, and 6 to 12 months using a piecewise linear model. Multivariable models adjusted for age, sex, diabetes, musculoskeletal functional</div> <div>limitations index and pain medication use.</div> <div>Results: Of the 150 participants included in our analysis, 19% were normal weight (BMI of &lt;25 kg/m2), 32% overweight (BMI of 25 to 29.9</div> <div>kg/m2), 27% class-I obese (BMI of 30 to 34.9 kg/m2), 12% class-II obese (BMI of 35 to 39.9 kg/m2), and 9% class-III obese (BMI of +40 kg/m2).</div> <div>Study participants with worse preoperative WOMAC (Western Ontario and McMaster Universities Osteoarthritis Index) had a higher BMI,</div> <div>pain and function scores and had greater improvement from baseline to 3 months. Across all BMI groups the mean change in pain and</div> <div>function from 3 to 6 and from 6 to 12 months was similar. At 12 months, participants in all BMI groups had similar levels of pain, function, and</div> <div>satisfaction.</div> <div>Conclusions: The variability of recovery in the 􀃶rst 3 months following total knee arthroplasty , the participants in the higher BMI groups</div> <div>were able to attain absolute pain and function scores similar to those in the non obese and class-I obese groups. The available data can be</div> <div>helpful for surgeons to discuss with the patients about their demands and functional recovery following Total knee Arthroplasty surgery,</div>
