Robotic-Assisted Total Knee Arthroplasty: Cruciate-Retaining Versus Bi-Cruciate Stabilized

In the researchers' words

The global prevalence of osteoarthritis of the knee with total knee arthroplasty performed is projected to substantially rise in the near future. This phenomenon is also observed in Hong Kong in which more than 4000 elective total joint replacement surgeries were performed in 2021 and over 30,000 patients are on the waiting list where some regions would have to wait for a median of more than 4 years. REAL INTELLIGENCE™ CORI™ (CORI Navigation) is a computer-assisted orthopedic surgical navigation and blurring system. CORI Navigation is designed to aid surgeons in planning and executing a procedure involving bone preparation for total knee arthroplasty (TKA) procedures. CORI Navigation is comprised of a console control unit, optical tracking camera, primary and secondary input displays (tablet and optional display monitor), and foot pedal. The CORI Navigation software consists of a patient and user management module, a surgical planner, and an intra-operative cutting module. Bi-Cruciate Stabilized (BCS) total knee arthroplasty (TKA) was designed for more kinematically functional implants that better reconstruct natural knee kinematics for activities of daily living. Surgical implant designs that resect the cruciate ligaments has emerged to simplify implantation and reduce surgical difficulty. The improvement of the biomechanical properties mimicking the natural kinematics of…
