OSTEOARTHRITIS
This was a single-center observational cross-sectional imaging study. Following ethical approval, MRIs of adult patients with suspected knee ligamentous injury in the period between 2017 and 2019 were eligible for inclusion. However, knees with imaging signs of osteoarthritis (albeit grade I), bony or cartilaginous defects, ligamentous injuries as well as those of patients with body mass index (BMI) ≥ 25 were excluded. Of the remaining total, 200 knees were classified as healthy, matched according to age into equal sex groups (100 males, and 100 females) and included in the imaging study.
