摘要: 本研究分析MRI测量胫骨结节-股骨滑车凹间距(tibial tuberosity-trocholear distance,TT-TG)、髌骨高度(patellar height,PH)、股骨滑车沟角(sulcus angle,SA)、滑车沟深度(sulcus depth,SD),与一次性髌骨外侧脱位(transient lateral patellar dislocation,TLPD)患者诊断及分型的关系。将2018年1月~2019年2月我院收治的50例TLPD患者作为观察组,50例膝关节正常者作为对照组。采用1.5 T MRI测量受试者TT-TG、PH、SA、SD水平,分析各指标单独应用及联合应用的诊断价值,并探讨其与临床分型的关系。结果显示,观察组TT-TG、PH、SA水平均明显高于对照组(P<0.05),观察组SD水平明显低于对照组(P<0.05);TT-TG、PH、SA及SD指标的联合应用可明显提高TLPD诊断的敏感度、特异度及准确度(P<0.05),且联合应用时AUC面积明显大于各指标单独应用,差异存在统计学意义(P<0.05);随着患者Dejour分型恶化,患者TT-TG、PH及SA水平均明显升高,SD水平随之明显降低(P<0.05);TT-TG、PH、SA及SD是影响TLPD患者临床分型的独立性影响因素(P<0.05)。研究结果表明,采用1.5 T MRI对TLPD患者的TT-TG、PH、SA、SD进行测量可有效提高临床诊断价值,且TT-TG、PH、SA、SD是影响患者临床分型的独立性影响因素。

Abstract: This study analyzed the relationship between TT-TG, PH, SA, SD measured by MRI and the diagnosis and classification of TLPD patients. Fifty TLPD patients admitted to our hospital from January 2018 to February 2019 were taken as the control group and 50 normal knee joints as the control group. TT-TG, PH, SA and SD levels were measured by 1.5 T MR imaging, and the diagnostic value of the indices used alone and in combination was analyzed, and the relationship between the indices and clinical classification was analyzed. The results show:the levels of TT-TG, PH and SA in the observation group were significantly higher than those in the control group (P<0.05), and the SD level in the observation group was significantly lower than that in the control group (P<0.05). The combined application of TT-TG, PH, SA and SD indicators could significantly improve the sensitivity, specificity and accuracy of TLPD diagnosis (P<0.05). The combined use of AUC with the four indicators was significantly higher than that of individual use, and the difference was statistically significant (P<0.05); with the deterioration of patients'Dejour classification, TT-TG, PH and SA levels were significantly increased, SD levels were significantly reduced, and the difference was statistically significant (P<0.05); TT-TG, PH, SA and SD were influencing the clinical manifestations of TLPD patients. The independent influencing factors of typing (P<0.05). This study demonstrated that measuring TT-TG, PH, SA and SD with 1.5 T MRI can effectively improve the clinical diagnostic value of TLPD patients, and TT-TG, PH, SA and SD are independent influencing factors of clinical classification.
