Bone marrow oedema (BMO), seen on magnetic resonance imaging, can be associated with various injuries to the knee but may also occur in asymptomatic athletes. The prevalence and causal factors for these observations are not well understood. The aim of this study was to determine the prevalence of BMO in asymptomatic knees of athletes, competing at a high level, and to investigate the associated factors.
Twenty-five asymptomatic university athletes, competing at regional to international level, were recruited. Bilateral knee magnetic resonance imaging was performed in each athlete (total 50 knee scans) at the end of their competitive season. Imaging studies were reported independently by two experienced consultant musculoskeletal radiologists.
There was almost perfect agreement between reporters for diagnosis of BMO ( = 0.896). Seven participants (28%) were found to have BMO (six in one knee and one bilaterally). The amount of time spent training, during the season, was significantly associated with the appearance of BMO ( < 0.05).
The occurrence of BMO in asymptomatic knees of athletes is common (occurring in over one-quarter of knees) and may be associated with training intensity. This should be considered when treating athletes and deciding upon appropriate treatment plans.
磁共振成像显示的骨髓水肿（BMO）可能与膝关节的各种损伤有关，但也可能发生在无症状的运动员身上。这些现象的患病率和因果因素尚未得到很好的理解。本研究的目的是确定高水平竞技的运动员无症状膝关节中BMO的患病率，并调查相关因素。
招募了25名在地区到国际水平参赛的无症状大学生运动员。在每个运动员的赛季结束时进行双侧膝关节磁共振成像（共50次膝关节扫描）。成像研究由两名经验丰富的肌肉骨骼放射科顾问独立报告。
报告者之间在BMO诊断方面几乎完全一致（κ=0.896）。发现7名参与者（28%）有BMO（6人单膝出现，1人双膝出现）。赛季期间的训练时间与BMO的出现显著相关（P<0.05）。
运动员无症状膝关节中BMO的发生很常见（超过四分之一的膝关节出现），并且可能与训练强度有关。在治疗运动员和决定适当的治疗方案时应考虑到这一点。
