Acetabular Impingement Exercises
Fig. 1. Sagittal (A) and coronal (B) fast spin echo (FSE) images of the ankle demonstrate an osteochondral lesion of the lateral talar dome with cartilage fibrillation, but no exposed bone (grade 2).

cartilage repair procedures have been used with osteochondral talar dome lesions, including debridement, arthroscopic drilling, mosaicplasty (osteochon-dral autograft), or retrograde drilling [4,8-10]. One study suggested that debridement of the remaining articular cartilage before drilling may yield improved results compared with drilling with the residual degenerated articular cartilage in place [10].

Cartilage degeneration in the subtalar, talonavicular, or naviculocuneiform joints can also be a source of pain in the posttraumatic ankle (Fig. 4).
