Summary
This trial compares two ways of performing knee replacement surgery: Mechanical Alignment (MA) and Kinemetic Alignment (KA). MA aims to have the new joint in a neutral position with respect to the thigh
Who is the study for?
This trial is for individuals with knee osteoarthritis needing replacement surgery. It's comparing two surgical methods: traditional Mechanical Alignment (MA) and the newer Kinematic Alignment (KA). Suitable participants should not have conditions that may interfere with the surgery or recovery.
What is being tested?
The study tests whether aligning the new knee joint to mimic natural anatomy (KA) has better outcomes than aligning it in a neutral position (MA). The focus is on patient-rated results, addressing gaps in previous research.
What are the potential side effects?
Potential side effects include pain, swelling, infection risk at the surgical site, blood clots, stiffness, and issues related to anesthesia. KA might reduce soft tissue damage since it avoids extra cuts.
