Are Computer-Controlled, Pressure Modulated Knee Rehabilitation Machines Valuable Following Knee Arthroplasty? - Orthopedics Research

Constant passive motion (CPM) machines have been used for decades. Initially, CPMs were supposed to accelerate rehabilitation, including range of motion (ROM) and function following total  knee arthroplasty (TKA). However, numerous studies show the CPM lacks efficacy following TKAs  [1-5]. Here, we document a new computerized pressure modulated knee rehabilitatio (PMKR) device, an FDA Class 1 medical device, (the X10TM, Halley Orthopedics, Franklin, MI, United States of America) [Figure 1,2] that utilizes pressure to increase RoM and strength of patient’s affected knees.
