The purpose of this study was to evaluate the association between the Soft Tissue Radiological Knee (SToRK) Index and the risk of developing a superficial surgical site infection (SSSI) following primary total knee arthroplasty (TKA).
The SToRK Index was measured using calibrated long leg radiographs (LLR) in 174 patients undergoing TKA.
A moderate correlation was found between the SToRK Index and body mass index (BMI) (r=0.574; p < 0.001). The SToRK Index was a better predictor of SSSI in females than males. In females, a SToRK Index cutoff of 2.01 had a sensitivity and specificity of 41.3% and 74.6% for developing SSSI, respectively, with a positive likelihood ratio of 1.63.
The SToRK Index can be used as an additional tool in assessing the risk for SSSI after TKA. It might be more predictive in females due to the different fat distribution compared to males.
本研究旨在评估软组织放射学膝关节（SToRK）指数与初次全膝关节置换术后发生浅表手术部位感染（SSSI）的风险之间的关联。
在 174 例行 TKA 的患者中，使用校准的长腿 X 线片（LLR）测量 SToRK 指数。
SToRK 指数与体重指数（BMI）之间存在中度相关性（r=0.574；p<0.001）。SToRK 指数在女性中比男性更能预测 SSSI。在女性中，SToRK 指数截点为 2.01 时，对 SSSI 的敏感性和特异性分别为 41.3%和 74.6%，阳性似然比为 1.63。
SToRK 指数可作为评估 TKA 后 SSSI 风险的附加工具。与男性相比，由于女性的脂肪分布不同，该指数在女性中的预测性可能更高。
