摘要: Almost nothing is known about the condition of knee joints multistage ultra-marathon (MSUM) runner. This first image-based investigation the femoropatellar joint (FPJ) using a mobile 1.5T MRI accompanying MSUM TransEurope Foot-Race (TEFR) 64 stages over 4486 km. Twenty-two (20 male) subjects got MRI-protocol at defined measurement intervals during TEFR: T2*-mapping (FLASH T2*-GRE), TIRM, and fat saturated PD -sequence. In FPJ 12 different regions were evaluated regarding cartilage T2* thickness changes cartilage lesions in course TEFR a test on possible compounding factors (running burden, BMI, age) was done if being appropriate. No significant thickness- and T2*-values found during TEFR. 8 runners, least one single lesion (Grade 2–3) baseline, but no significant race-related adjacent T2*-changes or progress defects could be detected. Analyses negative. knees with MPP (5) significantly lower found. The extreme running burden MSUM seems not to have relevant negative influence FPJ tissues, even if are present.
