Osteochondritis Dissecans of the Knee: What to Know case presentation A healthy, 21-year-old female presents with a 6 month history of persistent knee pain that worsens with activity She undergoes x-rays and juvenile osteochondritis dissecans of the knee is diagnosed. Which of the following is the most common area for juvenile osteochonditis dissecans and what site? Ankle, talus introduction Osteochondritis dissecans (OCD) is conventionally defined as a focal idiopathic alteration of subchondral bone with risk of instability and disruption of adjacent articular cartilage that may result in premature osteoarthritis.
This condition was initially described in 1887 and there are still challenges in regards to proper diagnosis and treatment. The most commonly affected joint is the knee , followed by the ankle, elbow, shoulder and hip. OCD is divided into juvenile and adult forms, depending on skeletal maturity at diagnosis.
The juvenile form of the disease (JOCD) presents in those aged five to 16 years with open growth plates. Most adult lesions are likely unresolved juvenile lesions, but de novo adult OCD has been described. The causes of OCD are unknown; however, repetitive trauma, inflammation, accessory centers of ossification, ischaemia and genetic factors have been proposed.
Boys have more risk of developing OCD in the knee (4 times) and elbow (7 times), whereas girls have more risk of OCD developing in the talus (1.5 times). The classic site of knee OCD is the posterior-central aspect of the medial condyle (63.6% to 85%) compared with inferior-central aspect of the lateral condyle (15% to 32.5%), inferomedial aspect of the patella (1.5% to 10%), and trochlea (2%). OCD usually involves a single site but can be multifocal within one or multiple joints with lesions in different stages.
Bilateralism occurs in knees (7.3% to 29%). Participation in high-level athletics is associated with the development of OCD in the knee (55% to 60%), elbow (84%), and talus (67.4%). Knee and talar OCD cases are commonly associated with soccer, football, and basketball, whereas elbow OCD is often seen in throwing athletes and gymnasts.
