Retroarticular drilling is an accepted option for stable knee JOCD when conservative treatment fails. The primary limitation of this technique is the requirement for fluoroscopy and its associated radiation. Intraoperative fluoroscopy can be a challenge because of the superimposed radiographic density of the musculoskeletal structures that may obscure visualization of the lesion in the lateral view. Consequently, most surgeries require multiple shots for the identification of the lesion and Kirschner-wire placement. We describe a new location assessment system that can, therefore, allow surgeons to more accurately identify the JOCD lesion during retroarticular drilling using radiographic landmarks. This technique may help avoid excessive intraoperative radiation and expedite intervention during the retroarticular drilling of osteochondritis dissecans lesions.
