Due to its important role in knee stability, after an ACL injury the knee starts moving abnormally from the inside. This leads to secondary damage to other structures such as the meniscus (shock absorber) or cartilage (toothpaste like lining of the knee). Damage to these structures can cause ongoing pain and swelling many days after an ACL injury or can also cause locking of the knee.
Another twisting injury can cause damage to other ligaments in the knee which will lead to a multiligament knee injury. The outcomes of surgery after a multiligament knee injury are generally inferior to the outcomes after a simple ACL surgery. So don’t let multiple twisting injuries happen before you come to us, come fast get fixed so you can have the best outcomes.
Further evidence shows that any ACL injury leads to early arthritis of the knee. With time the arthritis progresses and may lead to a knee replacement surgery.
