Fig. 1 Illustrations showing the locations of PF cartilage lesions by radiographic and gross assessments. The grey area in the gross finding illustrations means a significant cartilage lesion that was defined as a full-thickness lesion involving more than 50% of the index facet. Abbreviations: L, lateral side; M, medial side.

Fig. 2 A sample photograph for the evaluation of the gross cartilage conditions of the patella and trochlea (upper part of the dotted lines). The photographs were taken with two paper rulers placed perpendicular to each other for the facilitation of size determination.

Fig. 3 Photographs showing a typical sample for the three grades of cartilage lesions by the gross assessments. (A) minimal lesion, (B) moderate lesion, (C) severe lesion.
