ROMTECH PortableConnect Rehabilitation Device Usage Post Unilateral Total Knee Arthroplasty (TKA)

Randomized Multicenter Comparative Trial Evaluating the Impact of the ROMTECH PortableConnect Rehabilitation Device on Time to Recovery and Comprehensive Rehabilitation Outcomes Post Unilateral Total Knee Arthroplasty (TKA)

ROMTech is focused on transforming the healthcare market by delivering lower extremity rehabilitation systems that are effective, efficient for patient use, cost-effective, and provide better patient outcomes while simultaneously decreasing rehabilitation and overall recovery times.

The patented technology of the ROMTech PortableConnect can improve the rehabilitation protocol for lower extremities in shorter time periods. The focus of this study is to compare the effectiveness of the ROMTech PortableConncect device only rehabilitation program following total knee arthroplasty to an active comparator group of continuous passive motion with a standard of care combination HHPT and OPPT rehabilitation program. The technology used to develop the ROMTech PortableConnect device has been reported in a pilot study to tend to be highly effective in decreasing the recovery time of patients post TKA, as discussed in the findings from the pilot study with the ROMTech Pro Cycle. The expedited recovery resulting from use of the ROMTech rehabilitation technology is noted to be contributed to the ability of the ROMTech technology to achieve a more rapid range of motion in this patient population.
