Arthroscopic irrigation burn

A 28-year-old male underwent arthroscopically aided allograft ACL reconstruction in his right knee for symptomatic ACL insufficiency. The patient’s past medical history was unremarkable aside from an &dquo;allergy&dquo; to Forane (Anaquest, Madison, WI). He denied any dermatologic problems. Under epidural anesthesia, the leg was prepped with an iodine solution and elevated for 3 minutes. An upper-thigh tourniquet was then inflated to 350 mm Hg. An inflow cannula was inserted through a superior medial portal. The knee was inflated with warm normal saline irrigation solution, which was warmed in a heating cabinet. Arthroscopic examination of the knee demonstrated an old midsubstance tear of the ACL. Debridement, notchplasty, and insertion of guide wires for placement of the allograft ligament were performed under arthroscopic control, according to a previously reported technique.3 Cannulated reamers were then used to overdrill guide wires placed anteromedially and posterolaterally in the proximal tibia and distal femur, respectively, to accommodate the diameter of the allograft. The dependent reamed canal allowed a free flow of irrigation solution to escape. This was blocked, when technically feasible, with a rubber stopper. The procedure was completed uneventfully. After closure of the wounds, a sterile Jones dressing was applied with anterior-posterior splints. The patient was sent to the recovery room with a warm foot and
