Medication: mainly to relieve the symptoms of pain and prevent infection. Analgesic drugs, commonly used drugs include aspirin, ibuprofen, indomethacin, loxoprofen, diclofenac sodium and other drugs. Anti-infective drugs, mainly used before and after surgery to prevent the occurrence of infection, commonly used drugs include cefazolin and cefuroxime. 3. Surgery: i.e. ACL reconstruction.
