Study Comparing Recovery After Robotic-Assisted vs Manual Total Knee Replacement in Adults Aged 40 to 90

What this Trial Is About

This research aims to understand how patients recover functionally after total knee arthroplasty TKA, comparing robotic-assisted procedures to conventional manual ones. It focuses on whether robotic assistance leads to better perceived and actual functional recovery, including for revision and primary TKAs. The study combines patient-reported outcomes, functional tests, kinematic data, and wearable device information to provide a detailed timeline of recovery speed. Participants receive either robotic-assisted or manual total knee arthroplasty, either as a primary or revision procedure. There are four groups manual revision TKA, robotic-assisted revision TKA, manual primary TKA, and robotic-assisted primary TKA. Each participant undergoes six evaluation sessions one before surgery and five after surgery at 2 weeks, 6 weeks, 3 months, 6 months, and 1 year, with tests lasting about one hour at a physical therapy research center. During each visit, participants complete several questionnaires about joint function and quality of life, including Forgotten Joint, Promis 29, KOOS, and SF-36. They also perform functional tests such as Timed Up and Go TUG, walking speed tests, stair climb, balance tests, and others. Researchers may record video to track progress. The main outcomes measured include various timed and distance walking tests at all evaluation points to assess recovery over time.
