Abstract：
UNASSIGNED: This prospective study aimed to investigate the influence of weight difference between implanted prosthesis and removed bone in cementless total hip arthroplasty (THA) on hip awareness and patient-reported outcomes.
UNASSIGNED: A total of 48 patients (56 hips) who underwent primary THA were prospectively enrolled. Implanted prosthesis and removed bone were weighed intraoperatively. Forgotten Joint Score (FJS) and Western Ontario and McMaster Universities (WOMAC) scores were obtained before and at 1 and 3 months after surgery. Patients were divided into groups A, B, and C according to the percentile of the weight difference.
UNASSIGNED: The mean weight difference of the implanted prosthesis and removed bone was 117.97 ± 47.35 g. A negative correlation was found among the weight differences of the three groups and 1- and 3-month postoperative FJS (correlation coefficients, -0.331 and -0.734, respectively). A positive correlation was found among the weight difference of the three groups and 3-month postoperative WOMAC (correlation coefficient, 0.403). A significant difference in 3-month postoperative FJS and WOMAC scores was found among the three groups. The mean 3-month postoperative FJS (79.00) of group C was significantly lower than that of group A (93.32) (P < 0.05). The mean WOMAC score (15.83) of group A was significantly lower than that of group C (23.67) (P < 0.05).
UNASSIGNED: The implanted prosthesis is larger than the removed bone in cementless THA. The weight difference is negatively correlated with hip function. The weight difference should be minimized to achieve optimal hip joint awareness.

摘要：
■这项前瞻性研究旨在研究在非骨水泥全髋关节置换术（THA）中植入假体和切除骨之间的重量差异对髋关节意识和患者报告结果的影响。
■共有48例（56髋）接受原发性THA的患者被前瞻性纳入。术中称重植入的假体和切除的骨。术前以及术后1个月和3个月获得遗忘的联合评分（FJS）和西安大略省和麦克马斯特大学（WOMAC）评分。患者分为A组,B,和C根据重量差的百分位数。
■植入假体和切除骨的平均重量差异为117.97±47.35g。三组的重量差异与术后1个月和3个月的FJS呈负相关（相关系数，分别为-0.331和-0.734）。三组体重差异与术后3个月WOMAC呈正相关(相关系数,0.403)。三组患者术后3个月FJS和WOMAC评分差异有统计学意义。C组术后3个月平均FJS（79.00）明显低于A组（93.32）（P<0.05）。A组平均WOMAC评分(15.83)明显低于C组(23.67)(P<0.05)。
■在无骨水泥THA中，植入的假体比切除的骨骼大。体重差异与髋关节功能呈负相关。应最小化重量差异以实现最佳髋关节意识。
