Tibial tuberosity osteochondritis dissecans treatment mainly includes conservative treatment and surgery. 1. Conservative treatment: After 18 years old, the symptoms can disappear by themselves after the ossification of the tibial tuberosity and the upper end of the tibia, but the local augmentation will not change. Symptoms can be relieved by reducing strenuous knee activities before the age of 18. Physical therapy or short-term braking of the knee can also be supplemented for those with significant pain. Local injection of corticosteroids is generally not recommended, as subcutaneous injections will not be effective and the femoral epiphysis is difficult to inject. If the pain is severe, please consult a doctor for treatment. 2. Surgery: If the pain does not improve in adulthood, and the occasional small fragmented epiphysis does not fuse with the tibial tuberosity and the symptoms persist, tibial tuberosity drilling or implantation is usually used to promote fusion to achieve the goal of treatment. If the tibial tubercle is too large, it should be removed after the epiphysis is completely closed. Osteochondritis dissecans of the tibial tuberosity varies from case to case with different treatment options. If long-term symptoms are not relieved, it is important to seek medical attention and standardized treatment.
