This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This study is testing whether one type of artificial knee design works better than another for people having knee replacement surgery. Researchers will compare the MicroPort Medial Pivot Knee System with the Stryker Triathlon Tritanium knee system to see which design gives patients better pain relief, better movement, and better satisfaction after surgery.
Knee replacement surgery is very effective at reducing pain and improving how well people can walk and move. Two different artificial knee designs are commonly used, but doctors don't yet know if one design produces better results than the other. This study aims to directly compare them so doctors can make better recommendations in the future.

You will receive knee replacement surgery with one of the two artificial knee designs (your doctor will help determine which is right for you). You will then return to the clinic for follow-up visits before surgery, at 6 weeks, 6 months, 1 year, 2 years, 3 years, and 5 years after surgery. At some of these visits, you'll complete walking tests in a specialized gait lab, answer questions about how your knee feels and functions, and have clinical exams and X-rays to check on the implant.
