Soreness and swelling at the tibial tuberosity is a symptom of tibial tuberosity epiphysitis, which occurs in adolescents aged 12 to 16 years who often engage in strenuous sports, more often in males than females. It is a knee disorder that is caused by overuse and swelling of the tibial tuberosity. The following diseases are also causes of soreness and swelling at the tibial tuberosity: 1. Loss of glory Loss of glory is a rock swelling that occurs in the neck and behind the ear. It is similar to what modern medicine calls lymphatic metastatic cancer or malignant lymphoma of the neck. It is a neoplastic disease with the main manifestation of a hard rock-like neck mass, which does not move when pushed, the skin color does not change, the face is emaciated, the body is thin, and the shape is like a tree losing its glory. It is equivalent to primary malignant tumor of the neck and lymphatic metastasis of the neck of malignant tumor in Western medicine, such as lymphosarcoma, Hodgkin’s disease and nasopharyngeal cancer, laryngeal cancer of cervical lymph node metastasis and parotid cancer, etc. 2.Posterior tibial labrum fracture Posterior tibial labrum is also called posterior ankle. Posterior ankle fracture can occur in any type of ankle injury, and rarely occurs alone. If there is a large bone fragment in the posterior tibial labrum, it will damage the weight-bearing surface of the joint and affect the stability of the ankle joint. 3.Tibiofibular fracture Tibiofibular stem fracture (calf fracture) is the most common among the whole body fractures, and it is especially common in children under 10 years old. Single fractures of the tibial stem are the most common, followed by double fractures of the tibiofibular stem, and single fractures of the fibular stem are the least common. The tibia is the main weight-bearing bone attached to the lower femur, and the fibula is the important bone attached to the calf muscles and carries 1/6 of the weight. The lower middle 1/3 of the tibia is morphologically transformed and easily fractured, and the upper 1/3 of the tibia is fracture displaced, easily compressing the popliteal artery and causing severe ischemic gangrene in the lower calf, and the fracture stasis in the middle 1/3 of the tibia can close in the fascial compartment of the calf, increasing intra-compartmental pressure and causing ischemic muscle contracture into gangrene. Fractures of the middle and lower 1/3 of the tibia dissect the trophoid artery, predisposing it to fracture and delaying healing. Children can sometimes see “green branch fractures” of the tibia and fibula, and long-distance runners can also see “fatigue fractures” of the fibula.
