This study investigates the safety and performance of robotic-assisted total knee arthroplasty (RA-TKA) with specific knee systems called Skywalker and eMP. The purpose is to evaluate how accurately and reliably these systems can assist in knee replacement surgeries. The study also aims to understand the learning curve for surgeons using these systems, which refers to how quickly they can become proficient in using the technology. Additionally, it will assess the recovery of knee function in patients who receive the eMP knee with Skywalker assistance.

Participants in the study will undergo a series of procedures to measure different aspects of the knee replacement. This includes assessing the accuracy of the implant placement and alignment, as well as the knee's range of motion and function over time. The study will also monitor for any complications or adverse events that might occur during or after the surgery. A key part of the study is to compare these robotic-assisted procedures with traditional methods to determine if there are any improvements in outcomes.

• Who can participate: Adults aged 18 and older with joint diseases or deformities who are independent and ambulatory may participate. Participants must comply with evaluations, visits, and have signed consent, while those in other studies or with compliance issues are excluded.
• Study details: Participants will undergo robotic-assisted knee replacement using the Skywalker and eMP systems. The study compares implant accuracy and recovery with traditional methods.
