Patient: I went to play basketball in the afternoon of March last year after leaping over the guard, and felt a little pain in my right ankle after drinking at night, but it was not swollen, so I took a film and did not find it to be a fracture, and the doctor prescribed some medicine and ate it and it did not hurt, but later on, once I walked and did not land on my feet properly, I had a tearing pain inside my right ankle, and it was uncomfortable when I walked, and I had soreness in my wrist and on both sides of my heel. This has happened three times, and neither medication nor topical medicine works well. Last November, I had an MRI examination, and three doctors told me about three different conditions. According to their treatment plans, no significant results were seen. Laboratory and examination results: 1. abnormal signal in the right talus, considering bone marrow edema. 2. fluid in the right external ankle. 3. degeneration of the right ankle joint. In January of this year, we were seen at Nanjing Military General Hospital, and suspected ischemic necrosis of the talus, but the diagnosis was not confirmed. Doctor: According to your description, and the analysis of the examination results. It should be a cartilage injury of the talus formed after the impact of the tibial talar joint in the inversion or valgus position, also known as talar exfoliative osteochondritis, which is a more common disease in foot and ankle surgery. The good thing is that the injury took less than a year and you are relatively young, so you should be able to recover. However, I do not know your weight. The conservative treatment of this disease: Firstly, you need to reduce weight bearing and activities, and if necessary, you need to fix the cast and brake. Secondly, you can use some non-steroidal anti-inflammatory and pain-relieving drugs, or herbal medicines to activate blood circulation and remove blood stasis, as well as some cartilage matrix drugs like Vibramix or Glucophage. However, if the pain remains after regular conservative treatment or the function of the ankle joint is still limited, it is best to consider surgery. If the arthroscopic examination shows that the cartilage damage is larger in diameter, it is necessary to make a “mosaic” cartilage graft, which is a full layer of cartilage and subchondral bone graft from the knee joint, etc. The long-term effect of this surgery is still good. The long-term results of this procedure are good.
