The purpose of this research study is to compare two different methods used to align the knee during a total knee arthroplasty (TKA): technology-assisted inverse kinematic alignment, and manual-instrumented gap balancing alignment. The first technique uses robotic or computer-assisted technology to help the surgeon place the knee implant based on the patient's individual anatomy, whereas the manual technique uses standard surgical instruments and manual methods to position and balance the knee implant during surgery. The main difference is that one approach uses robotic or computer assistance to help guide implant positioning, while the other uses traditional instruments and manual surgical techniques. Both methods are commonly used and are considered standard care. The goal of this study is to understand whether one method results in better knee motion, function, and recovery after surgery in patients with higher body weight.
