Tibial intercondylar spine fracture on the outside of the knee should be difficult to limit the activity, immobilization, and at the same time, the knee MRI to determine the health of the bones and joints, medication or surgical treatment. 1. Restriction of activities: After a partial fracture, if you still maintain high intensity exercise, it is easy to cause slow healing or misalignment of bone healing. Therefore, activities should be restricted and joints should be immobilized and protected immediately after the fracture. 2. Conservative treatment: If the fracture site is not displaced and there is no collateral damage to the joint and its surrounding nerves and muscles and other collateral structures, external fixation and other conservative treatments can be carried out. 3. Surgical treatment: For displaced fractures or peripheral ligament injuries, timely surgical fixation and ligament repair are needed. During the period of fracture, the diet should increase the intake of calcium, which can help bone healing, promote the body to recover, and reduce the impact of fracture on the health of the body.
