BACKGROUND Labral tears are the most common findings in patients with symptomatic femoroacetabular impingement (FAI). The restoration of labral function is critical, and labral reconstruction has been proposed as an alternative for irreparable tears. PURPOSE To compare preoperative radiographic measurements and demographics of patients who underwent primary arthroscopic labral reconstruction versus primary labral repair and to identify factors that are predictive of the need for reconstruction. STUDY DESIGN Case-control study; Level of evidence, 3. METHODS Patients who underwent their index hip arthroscopic procedure between October 2010 and November 2018 and underwent either labral reconstruction or repair were included in the study. A total of 18 variables (14 radiographic and 4 demographic) were assessed in a bivariate comparison and analyzed in a multivariate logistic model. RESULTS A total of 251 primary reconstruction and 1147 primary repair procedures were included. The logistic model selected age, body mass index (BMI), Tönnis grade, lateral center-edge angle (LCEA), and alpha angle. The odds of reconstruction were 2.52 times higher in patients with Tönnis grade 1 than 0 (odds ratio [OR], 2.52 [95% CI, 1.82-3.49]). Each additional degree in the LCEA was associated with a 6% increase in the odds of reconstruction (OR, 1.06 [95% CI, 1.04-1.09]) and 4% for each additional degree in the alpha angle (OR, 1.04 [95% CI, 1.03-1.05]). Higher age (per log 10 unit) and BMI also increased the likelihood of reconstruction (OR, 11.29 [95% CI, 4.23-30.10] and OR, 1.03 [95% CI, 1.00-1.06], respectively). CONCLUSION In a multivariate analysis, factors identified as preoperative predictors for primary arthroscopic labral reconstruction in the setting of FAI and labral tears were Tönnis grade, LCEA, age, and BMI. These predictive factors may be useful for the clinician in determining the preoperative likelihood of primary labral reconstruction.

影像学和人口统计学因素可以预测髋关节镜手术中主要的唇重建的需求：一种使用1398臀部的预测模型。

背景唇泪是有症状的股骨髋臼撞击（FAI）患者中最常见的发现。唇功能的恢复是至关重要的，而唇修复已被提议作为不可修复眼泪的替代方法。目的比较进行初次关节镜下唇重建术与初次唇修复的患者的术前影像学测量结果和人口统计学特征，并确定可预测需要重建的因素。研究设计病例对照研究；证据等级，3。方法该研究纳入了在2010年10月至2018年11月之间进行了指数髋关节镜手术并且进行了阴唇重建或修复的患者。在双变量比较中评估了总共18个变量（14个射线照相和4个人口统计学），并在多变量logistic模型中进行了分析。结果总共包括251例初次重建和1147例初次修复程序。逻辑模型选择了年龄，体重指数（BMI），Tönnis等级，侧向中心边缘角（LCEA）和阿尔法角。Tönnis1级患者重建的几率是0的2.52倍（赔率[OR]，2.52 [95％CI，1.82-3.49]）。LCEA中每增加一个度数，其重建几率就会增加6％（OR，1.06 [95％CI，1.04-1.09]），α角每增加一个度数，就会增加4％（OR，1.04 [95％] CI，1.03-1.05]）。较高的年龄（每10单位log）和BMI也增加了重建的可能性（OR为11.29 [95％CI，4.23-30.10]和OR 1.03 [95％CI，1。00-1.06]）。结论在多变量分析中，被确定为FAI和唇泪的原发性关节镜下唇重建的术前预测因素为Tönnis级，LCEA，年龄和BMI。这些预测因素可能对临床医生在确定原发性唇重建术的术前可能性方面很有用。
