This trial is testing a new knee replacement device called the Empowr PS Total Knee Replacement to see how well it helps people walk after surgery. Researchers will measure how participants move their legs, how their muscles work, and their overall function at several time points after surgery. They'll compare these results to people who received other knee replacement brands and to healthy people without knee arthritis.
Knee arthritis can make walking painful and difficult, and knee replacement surgery is a common treatment. However, doctors want to understand whether this new design helps patients walk more naturally and function better than other available options.

If you're in the main study group, you'll undergo knee replacement surgery using the new device and computer navigation to guide the procedure. You'll receive standardized physical therapy following surgery. You'll then return for movement analysis visits before surgery and at 6 months and 1 year after surgery, where researchers will place reflective markers on your leg, attach small sensors to measure muscle activity, and video-record you walking on a special runway with embedded force plates. You'll also complete questionnaires about your knee function and pain at multiple visits over up to 10 years. Additional visits may include tests of stairs, balance, and sitting-to-standing movements.
