Research subject

Obesity is a well-reported risk factor for development and progression of knee osteoarthritis (OA). As obesity is a growing global problem, the number of patients receiving total knee arthroplasty (TKA) has increased over the past decades, leading to an increased number of revision surgeries. Obese patients are considered to have increased risk of revision. Furthermore, patients with obesity who have been subject to TKA have increased morbidity and mortality after the operation.
The aim of this research project is to study the influence of obesity on TKA. The first study, a register based cohort study, will evaluate if bariatric surgery before the TKA surgery on obese patients with knee OA has an impact on the prosthesis regarding revision.
