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.
