Abstract

One of the most prevalent hazards to orthopedic surgeons are musculoskeletal disorders with 97% of arthroplasty surgeons reporting procedural-related musculoskeletal pain and 66% of orthopedic surgeons reporting procedural-related musculoskeletal injury [1], [2], [3]. With the annual number of total knee arthroplasties (TKA) on the rise, orthopedic surgeons are taking on larger annual caseloads and retiring later in life [4], [5]. The goal of this study was to quantify postural demand for 11 discrete surgical steps of TKA to identify ergonomically unfavorable positions surgeons experience while operating. Four orthopedic surgeons performed TKA while their motions were recorded using marker-based motion capture. It was found that arthroplasty surgeons consistently experienced demanding cervical flexion with an average of 85.2% of the surgery. The surgical tasks found to be most demanding on the upper extremities and spine were drilling the femoral canal, gap assessment and balancing, anterior, posterior, and chamfer cuts, and tibial ream and broach. These surgical steps were determined to be high risk, as prolonged neck flexion and static shoulder flexion and abduction experienced during these surgical tasks are associated with musculoskeletal pain in the upper back and shoulder muscles [6].
