Abstract

Objective To measure the trade-off between risk of complications versus patient improvement in pain and function in orthopaedic surgeons' decisions about whether to undertake total knee arthroplasty (TKA). Methods A discrete choice experiment asking surgeons to make choices between experimentally-designed scenarios describing different levels of operative risk and dimensions of pain and physical function. Variation in preferences and trade-offs according to surgeon-specific characteristics were also examined. Results The experiment was completed by a representative sample of 333 orthopaedic surgeons (n=333): Median age 52 years, 94% male, 91% fully qualified. Orthopaedic surgeons were willin..
