Living with osteoarthritis can make daily movements painful and difficult. For many people, a total knee arthroplasty (TKA) is a major step toward regaining mobility. After surgery, patients typically begin a rehabilitation program to strengthen muscles and improve their range of motion. A recent large-scale review looked at whether using interactive remote rehabilitation—which involves two-way communication between patients and providers via technology—offers better results than traditional in-person methods for these patients.
The researchers analyzed data from over 2,600 adults who had undergone total knee arthroplasty. They compared those who used interactive remote rehabilitation with those who received conventional care. The goal was to see if the digital connection provided extra benefits for pain management, muscle strength, and overall quality of life.
The findings showed that interactive remote rehabilitation did not provide statistically significant advantages over traditional methods for most primary outcomes. This includes key areas like pain levels, patient-reported function, range of motion, and general health status. While there was a very small benefit noted for short-term active extension range of motion, the difference was not large enough to be considered clinically significant. Additionally, while some initial data suggested an improvement in quadriceps muscle strength for those using remote tools, this finding was not consistent when researchers performed more rigorous checks on the data.
It is important to note that the evidence from this study is considered low to very low in certainty. The researchers noted several limitations, including a lot of variation between the different studies they combined and wide margins of error in the results. Because the data was inconsistent across various measures, it is difficult to say with certainty how much impact the technology has compared to standard care.
For patients today, this means that while interactive remote rehabilitation is a possible way to receive care—especially if traveling to a clinic is difficult—it does not currently show a clear advantage over traditional in-person physical therapy. Patients should discuss their specific needs and access to transportation with their doctors to decide which rehabilitation path is best for their recovery.
