OBJECTIVE
To investigate patient factors influencing length-of-stay (LOS) after revision metal-on-metal (MoM) total hip arthroplasty (THA).
METHODS
We reviewed 23 hips undergoing revision of a MoM THA with minimum 2-year follow-up. A multiple linear regression was calculated to predict LOS using multiple variables.
RESULTS
Average length of stay (LOS) was 2.1 days. Multiple linear regression analysis identified a significant correlation between presence of an abductor injury (beta = 0.8886; < 0.0001), patient age (beta = -0.4452, = 0.0083), and pre-revision head size (beta = 0.4082; = 0.0172) with LOS (R = 0.6351, = 0.0002).
CONCLUSION
Patients with abductor injury, larger femoral heads, and younger age are at risk for longer LOS.
目的
探讨影响金属对金属（MoM）全髋关节置换术（THA）翻修术后住院时间（LOS）的患者因素。
方法
我们回顾了23例接受MoM THA翻修术且随访至少2年的髋关节病例。使用多个变量进行多元线性回归分析以预测住院时间。
结果
平均住院时间为2.1天。多元线性回归分析确定了外展肌损伤的存在（β = 0.8886；P < 0.0001）、患者年龄（β = -0.4452，P = 0.0083）和翻修术前股骨头大小（β = 0.4082；P = 0.0172）与住院时间之间存在显著相关性（R = 0.6351，P = 0.0002）。
结论
患有外展肌损伤、股骨头较大且年龄较小的患者住院时间较长的风险较高。
