Brief overview of the episode:
Osteochondritis Dissecans (OCD) is a process in which the blood supply to the end of a bone is interrupted. This results in bone softening or death and subsequently changes to the cartilage. In sever cases the cartilage will fall into the joint and cause locking.
The most common symptoms are pain, swelling, range of motion loss, weakness and reduction in sports performance. OCD mostly affects highly active adolescents between 10-20 years old. The mechanism is thought be repetitive low-level traumas sustained though running, jumping and cutting. But it is not fully understood and there is likely also a genetic component.
OCD has a prevalence of between 9-22/100,000, not too common. Because it shares so many symptoms with more typical knee juvenile complaints like tendonitis, bursitis, Osgood-Schlatter and growing pains it can be difficult to diagnosis. There are a few tests that can be done but in most cases an x-ray, MRI or CT scan will be the most conclusive.
It is really important to stop participation in sports if OCD is suspected because the possibility for long-term cartilage injury is present. The good news is that if the growth plate has not closed the potential for the bone and cartilage to heal is high.
If you or your child suspects that something is wrong please schedule and appointment with your local physical therapist, orthopedic surgeon or sports medicine doctor.
