The radiological and MRI appearances of 24 knees with patellar tendonitis resistant to conservative therapy were analysed to identify the characteristic MRI appearance and to determine if the patellar morphology was abnormal. A significant thickening of the tendon was found in all cases; this was a more reliable diagnostic feature than a high signal within the superior posterior and central aspect of the tendon at its proximal attachment. The site of the lesion shown by MRI is more compatible with impingement of the inferior pole of the patella against the patellar tendon than a stress overload of the tendon. There were no significant differences in the length of the patella, inferior pole or length of the articular surface when the patellar morphology was compared with that of a matched control group.
对24例经保守治疗无效的髌腱炎患者的膝关节进行放射学和MRI检查，以确定其特征性MRI表现，并判断髌骨形态是否异常。所有病例均发现髌腱明显增厚；与髌腱近端附着处上后方和中央区域内的高信号相比，这是一个更可靠的诊断特征。MRI显示的病变部位与髌骨下极撞击髌腱比髌腱应力过载更相符。将髌骨形态与匹配的对照组相比，髌骨长度、下极长度或关节面长度均无显著差异。
