  1. N absolute number of patients, % relative number of patients; Data of n = 1 patient is missing
  2. Significant correlations have been detected between the preoperative level of sports and the incidence of MRI pathologies (IFP edema). Higher incidences of MRI abnormalities among professionals and a homogenous distribution of MRI findings among amateurs have been observed (Chi-square-test: P < 0.001). IFP Infrapatellar fat pad
