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.
the study population consists of adult patients scheduled for elective, primary unicompartmental knee arthroplasty (UKA) at a high-volume orthopedic specialty center. This population includes individuals with symptomatic knee osteoarthritis limited to a single compartment (medial or lateral) who have failed conservative management. The cohort represents a broad range of body mass index (BMI) scores and age groups, reflecting the typical demographic of patients seeking partial knee replacement. Participants are selected based on the surgeon's clinical decision to utilize either a manual technique or a computer-assisted/robotic system, allowing for a real-world observational comparison of surgical physical demand.
Cohort
Prospective
Not listed
Surgeon Energy Expenditure (kcal)
The total metabolic energy consumed by the surgeon during the surgical procedure, measured in kilocalories (kcal).
Surgeon Heart Rate (BPM)
The average and peak heart rate of the surgeon, measured in beats per minute (BPM) to assess cardiovascular stress
Minute Ventilation (mL/min)
The volume of gas inhaled or exhaled from the surgeon's lungs per minute, used as an indicator of respiratory effort and physical exertion
Operative Time (Minutes)
Total time elapsed from the first incision to final skin closure. This is a critical variable as energy expenditure is often adjusted for the length of the case.
