Study of the KinexConnect Telerehabilitation System (KCTRS)

Randomized Study of the KinexConnect Telerehabilitation System Versus Outpatient Physical Therapy After Total Knee Arthroplasty

A randomized, single-blind study comparing telerehabilitation at home with continuous passive motion (CPM) and a tablet-based patient engagement application (KinexConnect) versus traditional outpatient physical therapy (PT) following total knee arthroplasty (TKA).

The Randomized Study of the KinexConnect Telerehabilitation System is a 1:1 randomized, single-blind, prospective cohort study to be conducted at one investigational site in the United States. The study compares at-home telerehabilitation system versus traditional outpatient PT following total knee arthroplasty (TKA). The telerehabilitation system involves a tablet-enabled patient engagement application, the KinexConnect App, to be used in conjunction with a continuous passive motion (CPM) machine.

7. Planned for bilateral TKA.
8. Self-reported pregnancy.
9. Reason for arthroplasty being for the treatment of fracture, infection or malignancy.
