摘　　要：目的:探讨单脚25°斜面下蹲功能动作在运动员髌腱病靶向诊断中的应用研究。方法:52名确诊为髌腱病的运动员为髌腱病组,匹配52名非髌腱病的运动员为非髌腱病组。测试者A使用组织特征超声成像(UTC)技术扫描并量化两组运动员髌韧带的组织结构。测试者B测试两组运动员在单腿25°斜面下蹲时膝关节的角度(SLDS-KROM)。以上均测试两次,取平均值。分别比较两组运动员髌韧带纤维类型回声分别占总纤维回声的比例、SLDS-KROM的差异;分别比较两组中Ⅰ型+Ⅱ型、Ⅲ型、Ⅳ型占比与SLDS-KROM的相关关系。结果:1)髌腱病组运动员髌韧带纤维类型回声比例与非髌腱病组运动员髌韧带纤维类型回声比例相比,Ⅰ型+Ⅱ型占比下降非常显著,而Ⅲ型和Ⅳ型占比上升非常显著。2)髌腱病组与非髌腱病组相比,SLDS-KROM下降显著。髌腱病组SLDS-KROM在35°~75°之间波动,非髌腱病组SLDS-KROM在74°~110°之间波动。3)髌腱病组和非髌腱病组中,Ⅰ型+Ⅱ型占比分别与SLDS-KROM呈非常显著正相关,而Ⅲ型和Ⅳ型占比分别与SLDS-KROM呈非常显著负相关。结论:运动员单脚25°斜面下蹲能力受到髌韧带组织结构的影响。SLDS-KROM随着髌韧带中Ⅰ型+Ⅱ型占比的上升与Ⅲ型和Ⅳ型占比的下降而增大。SLDS-KROM大于75°时,髌韧带组织结构处于正常状态;SLDS-KROM小于75°时,髌韧带组织结构处于异常状态。Objective:To explore the application of 25°single-foot slope squatting in targeted diagnosis of patellar tendinopathy in athletes.Method:52 athletes diagnosed with patellar tendinopathy are in the patellar tendinopathy group,and 52 athletes without patellar tendinopathy are matched in the non patellar tendinopathy group.Tester A used Ultrasound Tissue Characterization(UTC)to scan and quantify the tissue structure of the patellar ligament in two groups of athletes.Tester B tested the knee joint angle(SLDS-KROM)of two groups of athletes when squatting on a 25°slope with one foot.Tested the two twice and took the average.Compare the proportion of patellar ligament fiber type echoes to total fiber echoes and the differences in SLDS-KROM between two groups of athletes;Compare the correlation between type I%+type II%,type III%,type IV%and SLDS-KROM in two groups.Result:1)The proportion of echo types of patellar ligament fibers in athletes with patellar tendinopathy group was significantly lower than that in athletes without patellar tendinopathy group.The proportion of echo types of patellar ligament fibers in type I+II decreased significantly,while the proportion of echo types in type III and IV increased significantly,respectively.2)The SLDS-KROM decreased significantly in the patellar tendinopathy group compared to the non patellar tendinopathy group.The SLDS-KROM of the patellar tendinopathy group fluctuated between 35°and 75°,while the SLDS-KROM of the non patellar tendinopathy group fluctuated between 74°and 110°.3)In the patellar tendinopathy group and non patellar tendinopathy group,type I%+type II%were significantly positively correlated with SLDS-KROM,while type III%and type IV%were significantly negatively correlated with SLDS-KROM.Conclusion:The ability of athletes to squat on a 25°slope with one foot is influenced by the tissue structure of the patellar ligament.The SLDS-KROM increases with the increase of type I%+type II%and the decrease of type III%and type IV%in the patellar ligament.When the SLD
