Why the study?
Does peripheral nerve block anesthesia/analgesia improve outcomes in patients undergoing primary hip and knee arthroplasty?
Does peripheral nerve block anesthesia/analgesia improve outcomes in patients undergoing primary hip and knee arthroplasty?
Peripheral nerve block is strongly recommended for patients undergoing primary hip and knee arthroplasty based on moderate-level evidence.
Supports routine PNB integration into THA/TKA pathways; reinforces moderate-evidence consensus for regional analgesia in lower-extremity arthroplasty.
PNB use is recommended for patients undergoing THA and TKA except when contraindications preclude their use. Furthermore, the alignment of provider skills and practice location resources needs to be ensured. Evidence level: moderate; recommendation: strong.
