Optimization of postoperative management for pain relief in the event of knee joint diseases in overweight patients

The number of overweight people in the world is steadily increasing. This leads to an increase in the population suffering from osteoarthritis, which is one of the main causes of poor quality of life and disability among elderly patients. The disease is characterized by long-term pain syndrome, which reduces life satisfaction and significantly increases the level of discomfort. As a result, the demand for surgical interventions for lower limb joint replacement increases. Since excess weight and obesity create additional stress on the joints, which also increases the risk of developing the disease. Objective: To evaluate and compare pain relief efficacy following primary total knee arthroplasty between obese/overweight patients (BMI≥25) and normal-weight individuals at 3-, 6-, and 12-month postoperative intervals. Materials and methods. A prospective cohort study analyzed 120 cases stratified by BMI. Pain intensity was assessed using the Visual Analog Scale (VAS) in two patient groups with distinct weight-height profiles. Results. Both cohorts demonstrated significant postoperative pain reduction, with complete pain resolution achieved in all participants regardless of BMI status. Conclusion. In patients with gonarthrosis, regardless of the various factors leading to its occurrence, a favorable effect was noted regarding the exclusion of pain syndrome after total knee arthroplasty.
