There are many risks associated with surgery for degenerative knee osteoarthritis, such as postoperative infection, postoperative bleeding, thrombosis, and deterioration of joint mobility. However, the probability of the risks occurring after regular surgery in regular hospitals is very small, so patients do not have to worry too much. 1. Post-operative infection: If you don’t take good care of your knee, such as disinfecting the wound, changing the medication in place, and going down to the ground earlier than scheduled, and if you don’t cooperate with the follow-up treatment, post-operative infection may occur, and it may even cause serious damage to the knee joint and lead to knee joint lesions. 2. Postoperative bleeding: some patients will have local congestion after surgery, and there is a risk of postoperative bleeding. 3. Thrombosis: When bed rest is needed after surgery, blood flow will slow down and thrombus will be formed easily. 4. Deterioration of joint mobility: If the knee joint is inactive for a long time after the operation and lacks functional exercises for the knee joint, resulting in deterioration of the knee joint mobility, the normal knee joint function will be affected. In order to avoid the risk of degenerative knee osteoarthritis surgery, it is recommended to go to a regular hospital to find a high level of professionalism of the doctor to carry out the surgery to improve the success rate of the operation. After the surgery, we also need to do a good job of postoperative care according to the doctor’s instructions, timely disinfection and change of medication, and cooperate with the doctor to carry out postoperative treatment, so as to minimize the risk of surgery.
