This study evaluates the relationship between preoperative cartilage quality, measured by T2 mapping, and patient-reported outcomes following labral tear treatment. We retrospectively reviewed patients aged 14-50 who underwent primary hip arthroscopy with either labral repair or reconstruction. Preoperative T2 values of femoral, acetabular, and labral tissue were assessed from MRI by blinded reviewers. International Hip Outcome Tool (iHOT-12) scores were collected preoperatively and up to two years postoperatively. Associations between T2 values and iHOT-12 scores were analyzed using univariate mixed linear models. Twenty-nine patients were included (mean age of 32.5 years, BMI 24 kg/m, 48.3% female, and 22 repairs). Across all patients, higher T2 values were associated with higher iHOT-12 scores at baseline and early postoperative timepoints (three months for cartilage and six months for labrum; < 0.05). Lower T2 values were associated with higher 12- and 24-month iHOT-12 scores across all structures ( < 0.001). Similar trends were observed within the repair and reconstruction subgroups, with delayed negative associations correlating with worse tissue quality. T2 mapping showed time-dependent correlations with iHOT-12 scores, indicating that worse cartilage or labral quality predicts poorer long-term outcomes. These findings support the utility of T2 mapping as a preoperative tool for prognosis in hip preservation surgery.
本研究评估了通过T2映射测量的术前软骨质量与盂唇撕裂治疗后患者报告的结果之间的关系。我们回顾性分析了14至50岁接受初次髋关节镜检查并进行盂唇修复或重建的患者。由不知情的评估人员从MRI评估股骨、髋臼和盂唇组织的术前T2值。收集术前及术后两年内的国际髋关节结局工具（iHOT-12）评分。使用单变量混合线性模型分析T2值与iHOT-12评分之间的关联。纳入29例患者（平均年龄32.5岁，BMI 24kg/m²，48.3%为女性，22例进行了修复）。在所有患者中，较高的T2值与基线及术后早期时间点（软骨为三个月，盂唇为六个月）较高的iHOT-12评分相关（P<0.05）。在所有结构中，较低的T2值与12个月和24个月时较高的iHOT-12评分相关（P<0.001）。在修复和重建亚组中观察到类似趋势，延迟的负相关与较差的组织质量相关。T2映射显示与iHOT-12评分存在时间依赖性相关性，表明较差的软骨或盂唇质量预示着较差的长期结局。这些发现支持T2映射作为髋关节保留手术术前预后工具的实用性。
