We developed a regional anesthesia technique based on a selective anesthetic block of the femoral and sciatic nerves. This technique has been first applied to knee arthroscopy and then extended to major knee surgery. Here we report our experience on the first 500 cases: 326 arthroscopies, 73 ACL reconstructions, 37 tibial osteotomies, 25 synthesis of patellar fractures, 11 unicompartimental and 27 total knee prostheses. Mean surgical time was 44 ± 33 minutes (13-147 min). The selective neural block was performed by injecting a mepivacaine solution (7 mg/kg) near the femoral and sciatic nerves localized with the aid of an electric nerve stimulator. The efficacy of the technique has been evaluated on the basis of the ability to achieve an adequate anesthesia of the knee, a sufficient muscular relaxation, and on the satisfaction of the patient. Results were excellent or good in more than 80% of cases. 99% of surgical procedures were successfully completed with no need to recur to a more invasive anesthesia. Loco-regional anesthesia performed by the anesthetic bloc of the sciatic and femoral nerves proved to be suitable not only for knee arthroscopies but also for knee major surgery. The main advantages of this technique are: easy execution, low incidence of complications, low invasivity, hospitalization time and cost reduction.
