Avaliação funcional e do índice de massa corporal dos pacientes obesos submetidos à artroplastia total do joelho

Abstract

Introduction: Osteoarthritis is a degenerative disease that causes pain and stiffness, essentially. The method of choice for disease correction is total knee arthroplasty (KTA) or total knee replacement. Through BMI and WOMAC, weight loss and post-ATJ functionality are evaluated respectively. Method: A prospective longitudinal study was proposed to evaluate BMI in 3 stages: preoperative, 6-month postoperative and 12-month postoperative. A total of 14 obese individuals with a Body Mass Index = 30 were evaluated and evaluated over 12 months. The same individuals were also assessed using the WOMAC Function Index in the same 3 steps as defined for BMI. Results: There were no statistical differences between the 3 steps, taking into account the variable BMI. However, functionally, there was a significant improvement at 6 months and 12 months postoperatively when compared to the preoperative phase. Discussion: The causes that led to BMI results were not elucidated by the studies. Regarding the functionality, some articles justify the reduction of the WOMAC score and improvement of the function at six months, due to the TKA and the physiotherapeutic rehabilitation process in which they were submitted. Conclusion: The TKA provided relief of pain, improved quality of life and favored the recovery of functional kinetic frame at six and twelve months after surgery of obese patients. However, body mass index has been maintained over time, as dietary and daily habits can influence the maintenance of obesity.
