 Major surgical types for knee included arthroscopy, total or partial knee arthroplastic surgery. These procedures are typically associated with severe pain. Function training, which is imperative after surgery for these patients, also aggravated pain.Post-operative pain after major knee surgery impaired post-operative knee recovery and prolonged inpatient length of stay.To maximize the efficacy and minimize the side effects of different options,a multi-modal analgesic regimen was recommended for patients underwent knee surgeries.Local wound infiltration and nerve block are given considerable attentions.Compared with systematic analgesia,nerve block with local anesthetics has been revealed to provide superior analgesia and better recovery of joint function compared with systemic analgesics. Currently,systematic evidence is sparse related to the comparative efficacy of pain control between local wound infiltration and nerve block,the investigators therefore conduct this randomized controlled trials.
