Regional techniques have been shown to be effective after ACL reconstruction, allowing faster patient recovery with fewer side-effects than intravenous administration of opioids. Different regional techniques have been applied and studied after ACLR. Femoral nerve block for ACLR either as a single bolus or as a continuous infusion markedly decreases intravenous analgesic requirements and postoperative pain. To the Investigator's knowledge, no study has compared these two techniques after ACLR with patellar tendon graft or allograft.
