Summary

Studies have demonstrated that early rehabilitation interventions following knee arthroplasty (TKA) can shorten the time needed to regain baseline extension/full extension and gait mechanics. As telehealth visits and home-based rehabilitation increases with advancements in technology, much of this rehabilitation is projected to be performed at home. The purpose of this study is to prospectively evaluate early post-operative knee extension and self-reported outcomes in patients using the Zero Degree Knee positioner (ZDK) compared to subjects not using the ZDK. Patients electing to undergo primary TKA will be recruited into the study and randomized to receive and follow the ZDK protocol post-operatively or standard of care rehabilitation instructions. Knee extension measurements will be recorded at 2 weeks post-op and patient-reported outcome measurements will be recorded pre-operatively and at various post-op timepoints.
