Overview
Brief Summary
This study will evaluate blood flow restriction training as a rehabilitation modalities following total knee arthroplasty in order to determine if patient reported outcomes and objective functional outcomes can be improved through post-operative rehabilitation compared to standard physical therapy modalities currently in use.
Detailed Description
Patients will be enrolled preoperatively in order to measure preoperative functional measures. They will then be followed at predetermined intervals post-operatively. All subjects will begin the study related physical therapy 6 weeks post-operatively and continue for 12 sessions. At the conclusion of 12 sessions, subjects will be retested to determine improvement. Subjects will then be followed for two years post-operative.
