In clinical practice, we have seen an increase in sports injuries as people’s love of sports escalates, as well as an exponential increase in traumatic diseases due to car accident injuries, with ACL injuries to the knee being particularly prominent among them. What if you are unfortunate enough to injure your ACL? First of all, it is extremely important to find a real arthroscopic doctor, because only such doctors can treat this kind of disease, general orthopedic surgeons will be more concerned about your bones have no problems; secondly, find a doctor you are comfortable with, every year in my ACL patients, there is always a considerable part of me advised them to carry out conservative treatment, because this is more powerful for them. First, if you are unwilling to give up your old lifestyle, I recommend arthroscopic surgery. Two, if you have a combined meniscus tear, I still advise you to have your ACL reconstructed at the same time. Third, if you are over 50 years old, you can use conservative treatment, but you have a great possibility of traumatic osteoarthritis. If you are not willing to undergo surgery, you can use regular exercises for your knee joint. I can give you the best advice according to your specific situation. V. If your child is 14 years old or has an unclosed epiphysis, I urge you to come to me or a doctor experienced in this area to hear specific treatment options. Sixth, the learning curve for arthroscopic techniques is long, so if you want to operate, find an experienced physician, remember an experienced physician, not an older physician, as few hospitals would have had arthroscopic equipment ten years ago. Finally, I would like to say that you must not treat ACL rupture as a treatable disease, or you will regret it.
