Mako Robotic Arm Assisted Total Knee Arthroplasty
Tufts Medical Center
Jeffrey S. Zarin, MD
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.

Tobias Carling, MD, PhD, FACS
Associate Professor of Surgery

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.
