TKA with Zimmer Rosa Robot

Description

This video transcript features a detailed orthopedic surgery procedure conducted by Dr. Peter Sculco, involving the use of robotic assistance for a knee arthroplasty (knee replacement) surgery. The procedure begins with the insertion of tibial pins and the registration of the robotic system to ensure precision during the operation. Dr. Sculco explains the steps involved in placing femoral pins, registering anatomical points for accurate alignment, and assessing the gaps during flexion and extension of the knee using stress poses to evaluate the stability of the joint.



Throughout the surgery, Dr. Sculco demonstrates the collaborative mode of the ROSA robotic system, emphasizing its advantages in maintaining real-time adjustments for optimal resection plans without the need for pin placements. This portion of the surgery focuses on the cutting and placements of the femoral and tibial components while evaluating alignment with the precision tools provided by the robotic system. The anesthesia team's support responsibilities are also indicated, providing an overall teamwork approach.



Sequence analysis includes checking the gaps during extension and flexion to ensure proper tensions within the knee joint, assisting in establishing a well-balanced median for the tension gap. Measurements are taken to confirm that the components are fitting correctly, and adjustments to the planned cuts are made if necessary. Dr. Sculco discusses strategies for minimizing osteophytes, dealing with the posterior capsule, and achieving good cement usage for fixation.



The video concludes with final checks of alignment and stability of the knee joint, confirming proper functionality and indications that the procedure is successful. Dr. Sculco reflects on the progress of the surgery, results in extension and flexion, and the stability of the patella, ensuring that the patient would recover effectively post-surgery.
