This study assessed the ultrasound characteristics of the patellar tendon in two groups of volleyball players, one group without knee symptoms and one group with symptoms of jumper's knee. Of 47 male elite players, 25 were diagnosed to have current and seven to have had previous symptoms of jumper's knee, as determined by clinical examination. Since some players had bilateral problems, there were 34 knees with current problems and nine with previous problems. Seven of the 30 knees with a clinical diagnosis of jumper's knee in the patellar tendon had normal ultrasound findings, and ultrasound changes believed to be associated with jumper's knee (tendon thickening, echo signal changes, irregular paratenon appearance) were observed in 12 of 51 knees without symptoms. Specific ultrasound findings such as paratenon changes, hypoechoic zones or pathological tendon thickness proximally did not correlate significantly with the degree or the duration of symptoms. This study suggests that the specificity and sensitivity of ultrasonography is low in the evaluation of patients with mild symptoms of jumper's knee.
本研究评估了两组排球运动员髌腱的超声特征，一组没有膝关节症状，另一组有跳跃膝症状。在47名男性精英运动员中，经临床检查确定，25名被诊断为目前患有跳跃膝症状，7名曾有过跳跃膝症状。由于一些运动员存在双侧问题，因此有34个膝关节目前存在问题，9个曾有过问题。在髌腱临床诊断为跳跃膝的30个膝关节中，7个超声检查结果正常，而在51个无症状的膝关节中，有12个观察到被认为与跳跃膝相关的超声变化（肌腱增厚、回声信号改变、腱旁组织外观不规则）。诸如腱旁组织变化、低回声区或近端病理性肌腱厚度等特定超声表现与症状的程度或持续时间无显著相关性。本研究表明，超声检查在评估轻度跳跃膝症状患者时特异性和敏感性较低。
