Osteochondritis Dissecans of the Knee

Osteochondritis Dissecans of the Knee: Arthroscopic Suture Anchor Fixation

“…Osteochondritis dissecans (OCD) is a subchondral bone abnormality that affects the overlying articular cartilage with bony and cartilage fragmentation and may lead to degenerative changes. 1 Although the etiology remains unclear, repetitive microtrauma is the most accepted theory. The prevalence of OCD is approximately 15 to 29 cases per 100.000; male patients are affected more than female patients (5:3).…”

“…Magnetic resonance imaging can be performed to differentiate between abnormal ossification and OCD lesions; to measure the lesion size and depth, as well as the presence of any loose body; and to assess the stability of the lesion. 1 , 3 De Smet et al. 4 defined instability based on evaluation on T2 images: (1) high-signal intensity line beneath the lesion, (2) cystic area beneath the lesion, (3) high-signal intensity line through the articular cartilage, and (4) focal articular defect.…”

“…Juvenile OCD with a stable lesion is treated conservatively with medication and activity modification, with immobilization and decreased weight bearing. 1 , 2 , 5 Operative treatment is indicated for unstable lesions or lesions unresponsive to conservative treatment. The surgical option is based on the size and location of the lesion, amount of subchondral bone, and quality of articular cartilage.…”
