It can lead to ischemic lesions of the intercondylar ridge of the tibial plateau of the knee, such as tibial plateau osteophytes, anterior cruciate ligament injury, posterior cruciate ligament injury and so on. 1. Tibial plateau osteomalacia: due to the wear and tear of the tibial plateau caused by long-time walking, the bone around the intercondylar ridge will be proliferated, and the cartilage of the intercondylar ridge will be necrotic, which will compress the subchondral bone of the intercondylar ridge, thus affecting the blood circulation of the intercondylar ridge and leading to ischemic lesions of the intercondylar ridge. 2. Anterior cruciate ligament injury: the anterior cruciate ligament starts from the outer and posterior part of the intercondylar fossa of the femur, and then travels obliquely to the medial side and stops at the anterior side of the intercondylar ridge. When the anterior cruciate ligament is injured, it will pull the intercondylar ridge of the tibial plateau and cause injury, affecting the blood supply of the intercondylar ridge, which will lead to the occurrence of ischemic lesions. 3. Injury of the posterior cruciate ligament: the posterior cruciate ligament starts from the inner anterior part of the intercondylar fossa of the femur, then travels to the posterior lateral lower part of the femur and ends at the posterior side of the intercondylar crest of the tibia. Damage to the posterior cruciate ligament can cause instability of the knee joint, and if the damage is large, it can also cause an avulsion fracture of the intercondylar ridge of the tibia, which can lead to ischemic lesions due to impaired local blood circulation. Therefore, when ischemic lesions occur in the intercondylar ridge of the tibial plateau of the knee, it is important to pay attention to it and go to the hospital in time to get a clear diagnosis.
