Received one of the two analgesia regimens specified in this study postoperatively (fascia iliaca compartment block + patient-controlled intravenous analgesia or fascia iliaca compartment block + patient-controlled continuous nerve block analgesia), with no changes to the analgesic protocol throughout the treatment period; 4.Complete clinical data (including preoperative baseline data, surgery-related information, postoperative analgesia records, adverse reaction records, muscle strength assessment records, follow-up data, etc.); 5. Followed up postoperatively until discharge with complete follow-up data and no significant loss to follow-up.

Exclusion criteria

Exclusion criteria: 1.Patients with severe dysfunction of vital organs including heart, liver, kidney and lung, or with coagulation disorders or immune system diseases; 2.Patients with hypersensitivity to drugs used in the two analgesia regimens (local anesthetics, opioids, etc.); 3.Patients with preoperative hip muscle strength abnormalities or neurological diseases (such as Parkinson’s disease, hemiplegia, etc.) that may affect postoperative muscle strength assessment; 4.Patients who developed severe postoperative complications (such as prosthesis dislocation, infection, massive hemorrhage, etc.) affecting the evaluation of analgesic effect and muscle strength recovery; 5. Patients with severe missing clinical data (missing >=30% of key indicators such as VAS score, muscle strength grade, adverse reaction records) or loss to follow-up; 6.
