1 Evaluations of radiographic joint space – do they adequately predict cartilage conditions in the patellofemoral joint of the patients undergoing total knee arthroplasty for advanced knee osteoarthritis?  C.B. Chang, M.D., Ph.D., S.C. Seong, M.D., Ph.D., T.K. Kim, M.D., Ph.D.  Osteoarthritis and Cartilage  Volume 16, Issue 10, Pages (October 2008) DOI: /j.joca Copyright © 2008 Osteoarthritis Research Society International Terms and Conditions

2 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. Osteoarthritis and Cartilage  , DOI: ( /j.joca ) Copyright © 2008 Osteoarthritis Research Society International Terms and Conditions

3 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.
