The purpose of our study was to evaluate the knees of asymptomatic high-level collegiate basketball players before the beginning of the basketball season to gain an understanding of nonclinical findings in this patient population.
Bilateral knee MR imaging examinations of 17 varsity basketball players (12 men and five women) were performed before basketball season began. All of the subjects were imaged on a 1.5-T magnet. The MR imaging studies were reviewed by two musculoskeletal radiologists. Structures analyzed were the menisci, ligaments, cartilage, plicae, and bone marrow. The presence of a joint effusion was also noted.
Fourteen (41%) of the 34 knees had bone marrow edema, eight (24%) showed signal in the patellar tendon, and 14 (41%) had abnormal cartilage signal or a focal abnormality. Twelve (35%) of the 34 knees showed a joint effusion. Two knees (6%) showed abnormal signal along the infrapatellar plica. Four knees (12%) were noted to have a discoid meniscus.
An MR examination of the knees of high-level collegiate basketball players may show changes unique to this population. The changes seen on MR imaging in these athletes may be asymptomatic abnormalities. For instance, changes suggestive of patellar tendinopathy were identified in these asymptomatic subjects.
我们研究的目的是在篮球赛季开始前评估无症状的高水平大学篮球运动员的膝盖，以了解该患者群体的非临床检查结果。
在篮球赛季开始前，对17名大学篮球校队队员（12名男性和5名女性）进行了双侧膝关节磁共振成像检查。所有受试者均在1.5-T磁体上成像。磁共振成像研究由两名肌肉骨骼放射科医生进行评估。分析的结构包括半月板、韧带、软骨、滑膜皱襞和骨髓。同时记录是否存在关节积液。
34个膝盖中有14个（41%）出现骨髓水肿，8个（24%）髌腱有信号显示，14个（41%）有软骨信号异常或局灶性异常。34个膝盖中有12个（35%）出现关节积液。2个膝盖（6%）髌下皱襞有异常信号。4个膝盖（12%）发现有盘状半月板。
对高水平大学篮球运动员的膝盖进行磁共振检查可能会显示出该群体特有的变化。这些运动员磁共振成像上看到的变化可能是无症状的异常情况。例如，在这些无症状受试者中发现了提示髌腱病的变化。
