Chief, Division of Arthroplasty

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.

A 60-year-old female’s biochemical workup concluded she had primary hyperparathyroidism, and preoperative images suggested a left lower parathyroid lesion. Consequently, Dr. Tobias Carling performed a minimally invasive parathyroidectomy under local cervical anesthesia while preserving the esophagus and recurrent laryngeal nerve. Intraoperative PTH proved complete resection.

Program Director of Hand Surgery

Cubital tunnel syndrome, the second most common compressive neuropathy, causes tingling and numbness in the ring and small fingers and can be treated with either a cubital tunnel release or an ulnar transposition. In this case, Dr. Asif Ilyas demonstrates the former on a cadaveric hand.

PREPRINT RELEASE: De Quervain’s Release

De Quervain’s Release
Rothman Institute, Thomas Jefferson University
Asif Ilyas, MD, FACS
Professor of Orthopedic Surgery
Program Director of Hand Surgery

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.

PREPRINT RELEASE: Trigger Finger Release

Trigger Finger Release
Rothman Institute, Thomas Jefferson University
Asif Ilyas, MD, FACS
Professor of Orthopedic Surgery
Program Director of Hand Surgery

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.
