Measurements were taken in T2 maps at 6 and 12 weeks after partial or complete devascularization of the lateral trochlear ridge of the femur in ten piglets. Lesion types observed on histology at 12 weeks postoperatively are indicated in the last column (OCM: OC-manifesta; NSF: no significant finding).
