Background Effective rehabilitation following total knee arthroplasty (TKA) is crucial for enhancing both range of motion (ROM) and functional outcomes. While robotics has demonstrated its potential in various medical contexts, the evidence on its application in TKA rehabilitation is still scarce. The marsi active knee (MAK), a robotic device that has already proven to be safe and beneficial in people with neurological disease, has been tested to facilitate the rehabilitation of TKA patients. Objective This study aims to evaluate the safety, patient satisfaction, and clinical impact of integrating the MAK into an early rehabilitation regimen for TKA patients. Methods The intervention comprised 14 one‐hour sessions administered thrice a week, utilizing the MAK within 48 h post‐TKA surgery. The rehabilitation sessions incorporated exercises involving passive mobilizations, sit‐to‐stand transitions, and gait training. Comprehensive data encompassing safety parameters, patient satisfaction, and clinical outcomes were meticulously collected and analyzed. Results Six participants successfully completed the rehabilitation protocol with the MAK device. Notably, no significant adverse events were documented. Application of the device corresponded to perceptible reductions in self‐reported pain levels. Vital signs remained within minimal variance pre‐ and post‐rehabilitation. Participants proficiently engaged in all assisted exercises facilitated by the device, culminating in a high overall satisfaction rating of 4.6 ± 0.5 out of 5. Conclusion The findings indicate that the MAK device exhibits a commendable level of safety while obtaining considerable patient satisfaction during the early rehabilitation phase following TKA, suggesting this device may be a reliable adjunct to TKA protocols.
