There is an ongoing debate about the impact of the TT\u2013TG-distance on lateral patellar instability and the initiating of cartilage degeneration. In this prospective study, the association of T2* relaxation times and TT\u2013TG distances in professional soccer players was analyzed. 36 knees of 18 professional soccer players (age: 21\u2009\u00b1\u20092.8\u00a0years) were evaluated. Participants underwent knee MRI at 3\u00a0T. For qualitative image analysis, fat-saturated 2D PD-weighted Fast Spin Echo (FSE) and T1-weighted FSE sequences were used. For quantitative analysis, T2* measurements in 3D data acquisitions were performed. In a qualitative analysis there was no structural cartilage damage and no abnormalities of the patellar and trochlea shape. The highest T2* values (26.7\u2009\u00b1\u20095.9\u00a0ms) were observed in the central compartment of the patella. The mean TT\u2013TG distance was 10\u2009\u00b1\u20094\u00a0mm (range 3\u201320\u00a0mm). There was no significant correlation between TT\u2013TG distance and T2* relaxation times in all three compartments of the retropatellar cartilage. Our study shows that so long as patellar and trochlear morphology is normal, TT\u2013TG distance alone does not affect the tissue structure of the retropatellar cartilage in professional soccer players.<\/jats:p>","DOI":"10.1038\/s41598-020-72299-7","type":"journal-article","created":{"date-parts":[[2020,9,18]],"date-time":"2020-09-18T10:15:41Z","timestamp":1600424141000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Correlation of T2* relaxation times of the retropatellar cartilage with tibial tuberosity\u2013trochlea groove distance in professional soccer players"],"prefix":"10.1038","volume":"10","author":[{"given":"Kai-Jonathan","family":"Maas","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"Warncke","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.","family":"Behzadi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G.
