Actor Byun Yo-han also suffered from 'perfusion osteochondritis', what kind of disease is it?

He felt severe pain that made it difficult to walk due to a late recurrence in his leg, which he operated on 10 years ago due to an accident. The cause was 'Osteochondritis Dissecans (OCD)', which occurs when the cartilage layer of the knee joint is peeled off or falls off the joint.
Peeling osteochondritis refers to the separation of articular cartilage and subchondral bones (subchondral bone) when repeated loads or strong impacts are applied to the joint. When a strong impact is applied, the articular cartilage may bite and separate the bone below it, and in this case, it is called 'Osteochondral Fracture'.
This disease mainly occurs in the knee joint, and in addition, it occurs in joints such as ankles and elbows. Although patients with knee joint disease are mainly elderly, delamination osteochondritis occurs frequently in adolescents and active people in their early 20s. The exact cause has not yet been clearly identified.
It is known to be deeply associated with small but recurrent loads or micro-trauma associated with sporting activities (learning, jumping, etc.). It is known that repetitive loads cause problems in blood vessels that nourish the subchondral bone, resulting in necrosis due to impaired blood flow.
As such, delamination osteochondritis has a high risk of sudden occurrence in the knee joints of adolescents.
Kang Seung-baek, director of orthopedic surgery at Gangnam Bedro Hospital's knee joint center, explained, `The incidence of osteochondritis of knee joints is a rare disease that is about 10 to 30 cases per 100,000 people.' `It can occur in all ages and genders, but the risk of developing teenage adolescence is high, and men are known to be four times higher than women.'
In fact, according to data from the Health Insurance Review and Assessment Service, teenage patients accounted for the highest proportion of 21% of those who visited the hospital last year with delamination osteochondritis (dynamic osteochondritis disease code M93.2), and among them, teenage male patients account for 2.6 times that of women.
How can I avoid the sudden occurrence of 'knee arthritis' in active adolescence? The main risk factors for delamination osteochondritis, points to be aware of, and treatment methods were investigated in detail.
◇ Avoid exercises and activities that repeatedly and strongly impact the knee
Exercise and activities that give continuous impact to the knee are the main causes of delamination osteochondritis and are risk factors. It causes problems in blood circulation to the subchondral bone or causes fatigue fractures. In this way, the articular cartilage is separated from the lower bone, or it is separated by biting the bone. The separated joint cartilage or cartilage pieces become a loose body floating within the joint. When this glass body is caught between the knee joints, locking symptoms that do not extend or bend the joints appear. In addition, if a glass body gets stuck in a knee joint with a nearly zero friction coefficient, a third-party wear phenomenon in which joint wear progresses rapidly can lead to osteoarthritis (degenerative arthritis).
In particular, high-impact sports that place a large load on the joints are at high risk of osteochondritis. For example, excessive activities such as parkour (sports that go beyond buildings, cars, etc.) or professional players such as American football, basketball, and soccer are likely to have poor joints if their exercise intensity is high.
Director Kang Seung-baek emphasized "Be careful even if you suddenly give a shock without sufficient stretching."
"In fact, exercise in which landing, jumping, and rapid turning are repeated is likely to strain the knees and ankles. As ski resorts are opening in earnest, special attention should be paid to those who are waiting for winter sports such as skiing and snowboarding."
When delamination osteochondritis occurs in the knee joint, pain, swelling, and foreign body sensation in the joint occur. In addition to this, one of the characteristic symptoms is joint locking and limitation of the range of motion of the joint.
◇ If left unattended, secondary degenerative arthritis continues...'Weekend Warrior' Pattern Beware
Quick recognition of abnormal symptoms of peristaltic osteochondritis and early diagnosis and treatment are important. In the initial treatment, recovery without discomfort or aftereffects is possible even with a non-surgical method.
However, if the diagnosis is delayed after leaving symptoms unattended, it is likely to lead to chronic joint pain, reduced joint range of motion, and secondary degenerative arthritis. In particular, if the damaged joint cartilage is operated unrecovered, it will not only require surgical treatment, but also increase the possibility of progressing to secondary degenerative arthritis.
Director Kang Seung-baek emphasized that "in the case of peristaltic osteochondritis, the prognosis varies greatly depending on the stage of the lesion" and that "in particular, for active growing adolescents and athletes, getting an appropriate early diagnosis is the safest way to improve the prognosis".
In particular, ▲ a stabbing feeling in the knee ▲ a popping sound in the patella area ▲ If you continue to feel something submerged when bending and unfolding your knee, there is a high possibility that delamination osteochondritis has occurred, so it is recommended to see a specialist immediately for consultation.
In order to prevent delamination osteochondritis, it is recommended to avoid sudden high-intensity exercise above all else. In particular, it is recommended to avoid 'weekend warriors' type of exercise patterns as much as possible. This is because there is a high risk of putting a burden on the joint due to lack of muscle strength if you suddenly exercise without exercising normally. In particular, if you enjoy soccer and basketball, you must exercise enough muscle strength two to three times a week.
Director Kang Seung-baek said, `It is important to properly diagnose the disease and start treatment at a time that is not too late, especially since septal osteochondritis often occurs in adolescent patients in the growing season.' `If you feel pain in your joints or if your joints are uncomfortable, it is better to visit an orthopedic surgeon immediately for a thorough examination.'
