Chronic patellar tendinitis can be a frustrating diagnostic and therapeutic problem. This report evaluates seven tendons in five patients with chronic patellar tendinitis. The etiologies included "jumper's knee" and Osgood-Schlatter disease. In all cases magnetic resonance images (MRI) showed thickening of the tendon. Some of the tendons had focal areas of thickening which helped establish the etiology. All cases had intratendinous areas of increased signal which, in four cases, proved to be chronic tendon tears. MRI is useful in evaluating chronic patellar tendinitis because it establishes the diagnosis, detects associated chronic tears, and may help determine appropriate rehabilitation.
慢性髌腱炎可能是一个令人沮丧的诊断和治疗难题。本报告评估了5例慢性髌腱炎患者的7条肌腱。病因包括“跳跃膝”和奥斯古德-施拉特病。在所有病例中，磁共振成像（MRI）显示肌腱增厚。部分肌腱有增厚的局灶性区域，有助于明确病因。所有病例均有肌腱内信号增强区域，其中4例证实为慢性肌腱撕裂。MRI在评估慢性髌腱炎方面很有用，因为它能确立诊断、检测相关的慢性撕裂，并可能有助于确定合适的康复方案。
