目标。目的：评价休闲长跑运动员赛后膝关节的MRI研究结果，并评价研究结果的可逆性。八名休闲长跑运动员在参加维也纳马拉松比赛前、之后和6-8周后分别对膝盖进行了核磁共振检查。对这些研究就原有病变的改变和新的病理发现进行评估。在六名没有重大改变的跑步者中，没有经历任何负面影响。一名先前存在半月板III级改变的跑步者，在比赛2个月后出现进行性骨关节炎的迹象。在所有其他病例中，赛后半月板信号的增加和骨髓中的轻微信号变化都是一过性的。在健康的个体中，没有经历过负面的长期影响。先前存在的半月板高度损伤可能是由长跑压力引发的骨性关节炎的易感风险。
Objective. To evaluate the findings in MRI-studies of the knee in recreational long-distance runners after competition and to assess the reversibility of the findings.Design and patients. Eight recreational long-distance runners underwent MRI studies of the knee before, immediately after and 6-8 weeks after taking part in the Vienna City Marathon. The studies were evaluated regarding alterations of pre-existing lesions and new pathological findings.Results. In six runners without major pre-existing alterations no negative effects were experienced. In one runner with pre-existing grade III alterations of the menisci, signs of progressive osteoarthritis were experienced 2 months after the competition. In all other cases increased meniscal signal alterations and minor signal changes in the bone marrow after the race were transitory.Conclusion. In healthy individuals no negative long-term-effects were experienced. Pre-existing high-grade lesions of the menisci might be a predisposing risk for osteoarthritis, triggered by the stress of long-distance running.
