Blood Flow Restriction Training in Individuals Awaiting Total Knee Replacement

Twenty individuals ≥60 years old awaiting TKR due to diagnosis of end-stage knee osteoarthritis who meet the inclusion/exclusion criteria will be invited to participate in a 6 weeks of low-intensity BFRT prehabilitation. We will assess muscle functional (i.e., cross-sectional area and intramuscular fatty content) using computerized tomography, quadriceps muscle strength using an isokinetic dynamometer, a battery of performance-based physical function, self-reported physical function and quality of life, and biomarkers of inflammation using blood serum. Feasibility assessment will be done by looking at safety (i.e., adverse events), compliance, and attrition rate.
