Open and Closed Platform Robotic-assisted Versus Conventional Total Knee Arthroplasty

"In terms of technical specifications, KUNWU is the only robotic arm with seven degrees of freedom, while other systems have a maximum of six. The ergonomic and user-friendly design of the system contributes to physical relief and simplified instrument handling, which enhances surgical precision and reduces cognitive stress.~KUNWU's navigation system boasts a refresh rate of 335Hz, which is significantly higher than the current 60Hz rate of other navigation systems. This high refresh rate provides a clear and visually captivating display of the navigation procedure, eliminating blurriness and indecipherable output. It enables surgeons to react promptly during live procedures, enhancing safety for both clinicians and patients and reducing potential complications and hospitalization."

The CORI Surgical System (Smith and Nephew®) represents one of such recent advances in robotics that it can assist surgical planning, and increase the accuracy of implant position due to real-time feedback during the procedure (bone resection, implant position, ligamentous balance).

Total knee arthroplasty (TKA) is a highly successful and frequently performed surgical treatment to reduce disability caused by end-stage osteoarthritis and other conditions affecting articular cartilage. Technical outcomes for TKA are excellent, with favorable postoperative health-related quality of life. Also, survivorship of primary knee replacements is excellent with reported survivorship of 82.3% at 25 years. TKA has traditionally been indicated in the elderly population with relatively sedentary lifestyles, but more active, younger patients (\<55) are receiving TKA due to the desire for a pain-free, active lifestyle with the demand projected to continue to increase for this group. A recent systematic review has shown that functional outcomes are similar in this population compared to elderly patients with no increase in the burden of revision.
