Materials and Methods

We retrospectively reviewed charts of patients identified as having NPPE at the Hughston Sports Medicine Hospital (Columbus, Ga) from 1984 to 1999. Patient age, weight, height, length of time under general anesthesia, and type of surgical procedure were recorded. The admission history and physical examination, nurses' notes, and anesthesia records were reviewed for any comorbid conditions. The total number of similar inpatient and outpatient procedures done during the same period was obtained from our patient database. Procedures were considered similar when they involved the same or nearly the same instrumentation, surgical exposure, and anatomic location (eg, arthroscopic partial lateral meniscectomy and partial medial meniscectomy were considered similar procedures, as were primary anterior cruciate ligament reconstruction using interference screws and primary anterior cruciate ligament reconstruction using a post and washers). The research database included all procedures done by each of the physicians of our clinic and identified the hospital where the procedure was done. Data analysis was done using SPSS software, release 10.0 (SPSS Inc, Chicago, Ill). Significance was set at P < .05.
