The objective of this study was to investigate the impact of preoperative BMI on postoperative improvement in pain, function and general health status following total knee arthroplasty (TKA) from the patients’ perspective. It is not clear though whether BMI is associated with worse patient reported outcomes following TKA, as both equivalent outcomes and lower absolute post-operative scores have been proposed scaled by BMI class using various metrics.

These risks are often compounded by the associated comorbidities or other factors like socioeconomic status frequently found in such patients. Patients with an increased BMI have been reported higher in-hospital discharge rates and are accepted to have higher risks of postoperative wound dehiscence, infection, complications, and revision. Although increased BMI has been linked to the need for TKA, the impact of BMI on outcomes after TKA is less well established. By 2030, the respective number of overweight (BMI > 25 kg/m 2) and obese (BMI > 30 kg/m 2) adults is projected to be 1.35 billion and 573 million individuals. A quarter of the population of developed countries are reported as being obese. Worldwide levels of obesity (BMI > 30 kg/m 2 by WHO definition) are rising rapidly. Consequently, patients with increased BMI are more likely to require total knee arthroplasty (TKA) at younger age than patients with normal BMI. High BMI is also associated with a variety of metabolic disturbances such as coronary heart disease, hypertension and diabetes that could result in systemic risk factors for OA. Preoperative weight loss was found to have considerable implications for patient burden and cost reduction. Increased BMI is suggested to be one of the main modifiable risk factors of knee OA, given that every kilogram of weight loss leads to a fourfold reduction in the load exerted on the knee with daily activities. There is an established association between the patients’ body mass index (BMI) and knee OA, possibly due to increased mechanical loading at the joint.

Due to its well documented success, the number of TKAs performed increases every year and operative rates are reported to have doubled in the last decade. The improvements in patient health status achieved by TKA have been reported comparable to coronary revascularisation and renal transplant procedures. Total knee arthroplasty (TKA) is successful in alleviating the pain and disability associated with knee OA, and is one of the most commonly performed elective surgical procedures in orthopaedics. Osteoarthritis (OA) is a major global cause of disability, with the knee being the most frequently affected joint.

This trial has been registered with the ethics committee of Eastern Switzerland (EKOS Project-ID: EKOS 2020–00,879) Well balanced treatment decisions should fully account for both: Higher benefits in terms of pain relief and function as well as increased potential risks and complications. These findings suggest that obese patients may have the greatest benefits from TKA with regard to function and pain relief one year post-op. Post-operative improvement in joint-specific outcomes was larger in obese patients compared to normal weight patients. For WOMAC pain improvements were larger for all three obesity classes. In pairwise comparisons against normal weight patients, patients with class I-II obesity showed larger improvement on the WOMAC function and total score. All outcome measures improved between preoperative and 12-month follow-up ( p < 0.001). Resultsĭata from 1565 patients were accessed. Longitudinal score change was compared across the BMI categories identified by the World Health Organization. Data were collected preoperatively and 12-month postoperatively using WOMAC score and EQ-5D. MethodsĪ single-centre retrospective analysis of primary TKAs performed between 20 was performed. The aim of this study was to investigate the impact of body mass index (BMI) on improvement in pain, function and general health status following total knee arthroplasty (TKA). However, there is some controversy with regard to the influence of obesity on clinical benefits after TKA. Total knee arthroplasty is known to successfully alleviate pain and improve function in endstage knee osteoarthritis.
