Morbid Obesity and Severe Knee Osteoarthritis - Which Should Be Treated First?
Sponsor: Memorial University of Newfoundland
Summary
The goal of this study is to determine whether undergoing bariatric surgery before knee replacement leads to better outcomes compared to undergoing knee replacement before bariatric surgery. Our secondary goal is to compare complication rates between these groups to determine if there is a difference based on the order of the two procedures. Participants will be randomly placed in one of two groups, with each undergoing both procedures but in opposite order. Quality of life will be assessed via questionnaires before and between each procedure, and rates of complications will also be documented to compare their rates between groups.

Interventions
laparoscopic sleeve gastrectomy
Participants undergoing laparoscopic sleeve gastrectomy (LSG) will be clinically assessed and provided consent to this procedure by one of the bariatric surgeons affiliated with the bariatric surgery program. LSG will be performed at a local tertiary care hospital as either a day procedure or as an overnight stay if medically indicated. Patients will be discharged once they can tolerate a liquid diet. Patients will then attend regular follow-ups with their surgeons and the bariatric surgery program, in accordance with a standardized clinical pathway protocol.
total knee arthroplasty
Patients undergoing unilateral total knee arthroplasty (TKA) will be clinically assessed and provided consent to their procedure by an orthopaedic surgeon trained in joint arthroplasty. TKA will be performed at a local tertiary care hospital as either a day procedure or as an overnight stay if medically indicated. Patients will be discharged once physiotherapy clears them. Patients will attend regular follow-ups with their surgeon in accordance with a standardized clinical pathway protocol.
