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.
primary, elective unicompartmental knee arthroplasty (UKA).
Clinical and radiographic evidence of symptomatic unicompartmental knee osteoarthritis.
Candidates for either manual or computer-assisted/robotic cemented UKA.
Procedures performed by fellowship-trained arthroplasty surgeons to ensure technical consistency.
Revision Surgery: Patients undergoing revision knee arthroplasty (as the study focuses on primary cases).
Complex Scars: Presence of significant prior knee surgery or hardware that may abnormally increase surgical difficulty.
Inflammatory Arthritis: Patients with inflammatory conditions like rheumatoid arthritis (optional, depending on your focus).
Non-elective or trauma-related knee procedures.
