Surgeon Physiologic Stress

Placing the parts of a hip replacement requires substantial force. This can lead to additional stress on the surgeon as well as the bone. A device was developed to help reduce this stress. This study aims to see whether this device impacts implant positioning and the surrounding bone in patients 70 years and older. It also will investigate surgeon efficiency and how patients walk after surgery.

This study aims to compare the physiologic stress experienced by the surgeon during unicompartmental knee arthroplasty (UKA) performed using a manual technique versus a computer-assisted technique. Surgeon physiologic parameters, including energy expenditure, heart rate, heart rate variability, and minute ventilation, will be measured intraoperatively using a wearable monitoring device (Hexoskin). The study seeks to determine whether computer-assisted surgery influences surgeon workload compared to the conventional manual approach.
