title: Internal fixation of unstable Cahill Type-2C osteochondritis dissecans lesions of the knee in adolescent patients.
abstract: The treatment of osteochondritis dissecans lesions remains controversial. Twelve adolescent patients, with average 6-year follow-up, underwent compression screw fixation of unstable Cahill Type-2C osteochondritis dissecans lesions. Postoperatively, patients were evaluated with several functional tests and scoring systems, including Lysholm, IKDC, and KOOS. All lesions healed, and no clinical or radiographic evidence of degenerative disease was noted. No significant differences in thigh girth, range of motion, stability, or single-leg-hop distance was observed when compared to the unaffected, contralateral extremity. This technique is appropriate and efficacious for the treatment of unstable osteochondritis dissecans lesions.
