Expert Surgeons Can Be Distinguished From Trainees, and Surgical Proficiency Can Be Defined, Using Validated Metrics and Shoulder Models.

Experts at performing arthroscopic shoulder Bankart procedures can be distinguished from surgical trainees using validated metrics and a cadaveric or simulator model. The combination of performance metrics plus models generates a tool that can be used to precisely and accurately define a performance threshold and assess whether or not a surgeon is proficient at performing a procedure. A tool that can be used to judge surgical expertise has implications for training and credentialing. Experienced surgeons make fewer mistakes and are faster than novices.
