In this case a 66-year-old patient presents with arthritis predominantly in the medial compartment. Dr. Jeffrey Zarin explains how to use the Mako robot to precisely plan and perform a total knee arthroplasty surgery on this patient. Preoperatively, he uses a CT scan to create a model of the patient in order to determine the appropriate implant size, and intraoperatively, he utilizes the Mako robot to assist in ligament and gap balancing, perform the osteotomies, and make precise corrections.

Instead of conducting a De Quervain's release on a patient with stenosing extensor tenosynovitis, Dr. Asif Ilyas walks through the procedure on a cadaver, demonstrating the approach to the first dorsal extensor retinaculum and providing tips to release it without injuring the radial sensory nerve.

When the flexor tendons of the hand thicken or become inflamed, stenosing flexor tenosynovitis of the hand (also known as trigger finger) develops. Dr. Asif Ilyas demonstrates on a cadaver how to perform the most standard trigger finger release, releasing the A1 pulley and then decompressing or releasing the flexor tendon.
