In an Open Anterior Cruciate Ligament (ACL)repair,an Examination Under Anesthesia

In an open anterior cruciate ligament (ACL) repair,an examination under anesthesia (EUA) is performed immediately after induction of anesthesia,when the ligaments are completely lax,to evaluate the severity of the injury.The surgeon then makes a straight midline or slightly medial incision across the knee.Arthroscopic repair causes less patellar pain and decreased disturbance of extensor mechanisms.What preoperative indicators contribute to selecting the surgical approach (open or arthroscopic) of choice?

A) Classification and severity of the tear or capsular instability
B) Surgeon experience and preference
C) Patient history of a prior failed repair or gross knee joint disruption
D) Surgeon's choice of whether to use autograft or allograft to replace the torn ligament.
