Intraoperative assessment of labral quality determines arthroscopic repair versus reconstruction for hip labral tear treatment. T2 mapping technology discriminates between healthy and damaged cartilage. This study investigated if T2 mapping magnetic resonance imaging (MRI) can preoperatively predict labral repair versus reconstruction. This retrospective comparative study included patients with preoperative T2 mapping MRI who underwent hip labral repair or reconstruction at a single institution between March 2021 and February 2023. Three reviewers using Syngo.via recorded average T2 mapping values for the labrum, acetabular cartilage, and femoral cartilage on patients' sagittal cut. Intraclass correlation values estimated rater agreement of T2 values. T2 means were compared using -tests. Three Bayesian regression models were created, separately analyzing the labrum, acetabular cartilage, and femoral cartilage mapping values. The 95% credible intervals determined the significance of regression coefficients. A total of 63 operations were included: 14 reconstructions and 49 repairs. Participants were 14- to 50-years-old, with 35 females and 28 males. There was excellent agreement among raters for T2 measurements. There was no significant difference in average T2 values between the repair and reconstruction groups. All three models showed that the odds of labral reconstruction were negatively associated with T2 mapping values, positively associated with age, and increased in males. Preoperative T2 mapping values from the labrum, acetabular, and femoral cartilage are negatively associated with the odds of needing a labral reconstruction. Increased age and being male are associated with increased odds of needing a labral reconstruction. This study will allow further evaluation into other variables that predict labral repair versus reconstruction.
术中对盂唇质量的评估决定了髋关节盂唇撕裂治疗采用关节镜修复还是重建。T2 映射技术可区分健康软骨和受损软骨。本研究调查了 T2 映射磁共振成像（MRI）能否在术前预测盂唇修复与重建。这项回顾性比较研究纳入了 2021 年 3 月至 2023 年 2 月期间在单一机构接受髋关节盂唇修复或重建且术前行 T2 映射 MRI 的患者。三名使用 Syngo.via 的审阅者记录了患者矢状面上盂唇、髋臼软骨和股骨软骨的平均 T2 映射值。组内相关值估计了 T2 值的评分者一致性。使用 t 检验比较 T2 均值。创建了三个贝叶斯回归模型，分别分析盂唇、髋臼软骨和股骨软骨的映射值。95%可信区间确定了回归系数的显著性。共纳入 63 例手术：14 例重建和 49 例修复。参与者年龄在 14 至 50 岁之间，女性 35 名，男性 28 名。评分者之间对 T2 测量的一致性极佳。修复组和重建组的平均 T2 值无显著差异。所有三个模型均显示，盂唇重建的几率与 T2 映射值呈负相关，与年龄呈正相关，且在男性中增加。盂唇、髋臼和股骨软骨的术前 T2 映射值与盂唇重建的几率呈负相关。年龄增加和男性与盂唇重建几率增加相关。本研究将允许对预测盂唇修复与重建的其他变量进行进一步评估。
