Background: Osteochondritis dissecans (OCD) is a lesion of subchondral bone that can lead to delamination and sequestration of the fragment, with the potential for pain upon use of the affected joint. The cause of OCD is still not known, however, it is believed that repeated trauma and genetics play a role.
Purpose: Here we present two cases of homozygous female twins with similar talus OCD lesions that underwent surgical intervention with arthroscopically-assisted drilling of the lesion.
Results: Radiographic and qualitative followup demonstrates complete healing and return to function of both patients. Discussion: Genetic linkage with OCD prevalence may play an important factor in disease recognition. Early surgical intervention may play a stronger role in definitive treatment modalities.
