Clinical Trial Summary

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.


Clinical Trial Description

The primary objectives of the POMELO study are to determine if a multicomponent behavioural intervention that includes personalized nutrition recommendations, progressive resistance training exercise, and chronic disease self-management support is feasible and acceptable for individuals living with advanced knee OA and a BMI ≥35 kg/m2. The secondary objectives are to assess potential effects of the intervention on muscle mass and physical function compared to usual care. The intervention is delivered over three months, followed by six months of ongoing maintenance support. Assessments are completed at baseline, interim (after the 3 month intervention phase), and at study end (after the 6 month maintenance phase) [for a total study period of 10 months]. This project will inform and influence the future development and implementation of more personalized knee OA treatment approaches for adults with a BMI ≥35 kg/m2 and reduce health disparities in access to effective care. Findings will also contribute to improved health outcomes for this vulnerable patient population, and enhanced delivery of health services by offering an alternative treatment pathway targeted to patient needs. ;
