1 Operative Treatment of Osteochondral Lesions of the Talus by Christopher D. Murawski, and John G. Kennedy J Bone Joint Surg Am Volume 95(11):1045-1054 June 5, 2013 ©2013 by The Journal of Bone and Joint Surgery, Inc.

2 After curettage and debridement of the defect, removal of the calcified layer at the base of the defect is of critical importance in the procedure in order to facilitate clot adhesion15.

3 Coronal cartilage-sensitive fast spin-echo MRI study, acquired twenty-five months following microfracture of the lateral margin of the talar dome, demonstrates depression of the subchondral plate and overlying high-signal-intensity repair cartilage (arrow).

4 Corresponding coronal quantitative T2 map demonstrates diffuse prolongation of T2 values and loss of color stratification at the site of cartilage repair (arrow), representing immature repair cartilage.

5 One or more tubular units of viable hyaline cartilage and bone (circles in inset) are harvested from the ipsilateral knee and transplanted into the defect site of the talus in a press-fit configuration.

6 Coronal cartilage-sensitive fast spin-echo MRI study of an autologous osteochondral plug (arrow) transplanted into the medial margin of the talar dome demonstrates good fill of the cartilage defect and restoration of the radius of curvature of the articular...

7 Corresponding coronal quantitative T2 map demonstrates normal color stratification of T2 values at the site of cartilage repair (arrow), similar to that of native cartilage. Christopher D.

8 A fresh osteochondral allograft is harvested from a donor talus matched to the size and radius of curvature of the native articular surface (left). Christopher D. Murawski, and John G. Kennedy J Bone Joint Surg Am 2013;95:1045-1054 ©2013 by The Journal of Bone and Joint Surgery, Inc.
