摘要/Abstract

摘要： 探讨MRI定量参数对剥脱性骨软骨炎（OCD）的诊断价值及与微骨折术后康复效果的评估价值，选取100例篮球运动员踝关节OCD患者作为观察组，另选取同期100例因踝关节损伤入院的非OCD患者作为对照组。所有患者均行3.0T磁共振扫描，比较两组患者的MRI定量参数[T2指数、骨髓水肿（BME）、厚度指数]，分析MRI定量参数对踝关节OCD的诊断价值。比较微骨折术治疗后不同康复效果患者的MRI定量参数及美国足踝外科协会评分（AOFAS），分析MRI定量参数与AOFAS评分的相关性，评价MRI定量参数对踝关节OCD患者微骨折术后康复效果不佳危险度的影响。结果显示，观察组MRI定量参数T2指数、BME较对照组高，厚度指数较对照组低（P<0.05）。T2指数、BME、厚度指数联合诊断踝关节OCD的AUC为0.922，高于单一指标。踝关节OCD微骨折术后康复良好患者术后MRI定量参数T2指数、BME均低于康复不佳患者，厚度指数、AOFAS评分高于康复不佳患者（P<0.05）。踝关节OCD微骨折术后术前MRI定量参数T2指数、BME与AOFAS评分呈负相关关系，厚度指数与AOFAS评分呈正相关关系（P<0.05）。MRI定量参数T2指数、BME、厚度指数高水平患者微骨折术后康复不佳发生风险是低水平患者的18.667倍、10.625倍、0.135倍。踝关节OCD患者MRI定量参数T2指数、BME较高，厚度指数较低，且MRI定量参数与微骨折术后康复效果相关。

Abstract: This paper investigated the diagnostic value of quantitative MRI parameters on exfoliative osteochondritis (OCD) in basketball players and the assessment value on rehabilitation effect after microfracture surgery. 100 patients with ankle OCD were selected as the observation group, and another 100 patients in the same period with non-OCD admitted for ankle injury were selected as the control group. All patients underwent 3.0T MRI scans, and the MRI quantitative parameters[T2 index, bone marrow edema (BME), and thickness index] were compared between the two groups as well as to analyze the diagnostic value of MRI quantitative parameters for ankle OCD. Compared the MRI quantitative parameters and American Foot and Ankle Surgery Society score (AOFAS) scores of patients with different rehabilitation outcomes after microfracture surgery treatment, and analyzed the correlation between MRI quantitative parameters and AOFAS scores, and evaluated the influence of MRI quantitative parameters on the risk of poor rehabilitation outcomes after microfracture surgery in patients with ankle OCD. The results showed that the quantitative MRI parameters T2 index and BME were higher and the thickness index was lower in the observation group than in the control group (P<0.05). The AUC of the combined T2 index, BME, and thickness index for the diagnosis of ankle OCD was 0.922, which was higher than that of the single index. The postoperative quantitative MRI parameters T2 index and BME were both lower in patients with good recovery after ankle OCD microfracture surgery than in patients with poor recovery, and the thickness index and AOFAS scores were higher than in patients with poor recovery (P<0.05). The preoperative MRI quantitative parameters T2 index and BME were negatively correlated with the AOFAS score and the thickness index was positively correlated with the AOFAS score after ankle OCD microfracture (P<0.05). The risk of poor postoperative rehabilitation after microfracture occurred 18.667, 10.625, and 0.135 times higher in patients with high levels of MRI quantitative parameters T2 index, BME, and thickness index than in patients with low levels. Patients with ankle OCD had higher MRI quantitative parameters T2 index, BME, and lower thickness index, and the MRI quantitative parameters were associated with the outcome of postoperative rehabilitation of microfractures.
