Surgical drilling of osteochondritis dissecans (OCD) lesions is a commonly performed treatment for stable lesions in skel-etally immature patients. Drilling of OCD lesions is thought to facilitate healing by creating channels in the subchondral bone, which allow revascularization and, ultimately, bony union of the fragment.¹ Outcomes of retroarticular and transarticular drilling techniques have been reported by multiple authors to produce high rates of healing.¹,² Transarticular drilling penetrates the articular cartilage to access the subchondral bone. Concerns with this technique have been the long-term consequences of perforating the articular cartilage. In contrast, retroarticular drilling allows perforation of the subchondral bone without violating the articular cartilage. Concerns with retroarticular drilling involve the need for intraoperative fluoroscopy and the potential for incomplete drilling because the lesion cannot be visualized directly. In a recent systematic review of the literature comparing transarticular drilling with retroarticular drilling, Gunton et al.¹ concluded that both techniques produced high rates of radiographic healing and comparable patient-oriented outcomes.
