Once a meniscus injury with a barrel stem tear occurs, surgery is recommended as soon as possible, as conservative treatment often fails to solve the problem. A barrel stem tear of the meniscus is a more serious type of meniscus injury. After the tear, the medial meniscus will move to the middle of the joint and can encase the medial femoral condyle or femoral epicondyle, resulting in interlocking of the entire joint. Interlocking is a sudden inability to move, and the foot cannot be straightened and flexed. If the interlock occurs while walking down stairs or climbing a mountain, it can be dangerous and older people may fall and fracture other parts of the joint. If a barrel stem tear is treated surgically early, it can be sutured arthroscopically, and the long-term results are excellent. Therefore, once a barrel stem tear is detected, it is important to follow the guidance of a sports medicine doctor or orthopedic surgeon as soon as possible and to actively pursue early surgical treatment. After the meniscus has healed, you can participate in normal sports activities, including basketball and soccer, after the meniscus has healed. Therefore, there is no need to panic about surgery, as surgery will bring good treatment results for barrel stem meniscus tears.
