Treatment options for individuals who have advanced knee osteoarthritis (OA) and a body mass index (BMI) ≥35 kg/m2 are limited, and this patient population may be neglected in current clinical care pathways for OA management. These individuals are considered to be at high risk for complications with total knee arthroplasty (TKA), and as a result may not be eligible for this procedure unless they lose significant weight. However, there is limited evidence for endorsing weight loss as beneficial prior to TKA. Further, unsupervised weight loss could put patients at risk for muscle loss and development of sarcopenic obesity, a health condition that negatively impacts mobility and mortality. This suggests that weight loss might not be the primary treatment goal for this patient population. Integrated non-surgical treatment approaches are needed that can target the specific needs of this knee OA patient group. This study will examine the feasibility and acceptability of a personalized, multicomponent intervention, and its effects on body composition and physical function compared to usual care.
