Key outcomes included surgical trauma (blood transfusion rate, hospital stay, and surgery time), muscle damage [magnetic resonance imaging (MRI) and serum creatine kinase (CK) and C-reactive protein (CRP) levels], functional recovery [Harris hip score (HHS), short form (SF) score], and postoperative complications (dislocation rate, nerve injury rate, intraoperative fracture, infection rate, and leg length discrepancy). The gene discussed is CRP; the disease is infection.
