Things to Know about A Torn ACL

by Kevin Smith Author

One of the most common knee injuries among athletes is a torn ACL, especially in sports that involve a lot side movement, running, and jumping. If you injured your knee and the knee doctor in Renton, WA, has confirmed a torn ACL diagnosis, you probably have many concerns about the injury and the treatment required. Here's what you need to know.

What's the ACL?

Many people are unfamiliar with what the ACL actually is. ACL stands for Anterior Cruciate Ligament, which is the ligament that runs diagonally through the knee to stabilize it. Its prominence is a major reason it's more prone to injury than other ligaments. However, about 50% of ACL injuries often include damage to other parts of the knee as well.

What Causes Torn ACLs?

Although torn ACLs often happen in contact sports, the actual contact itself doesn't usually cause the tear. Rather, the damage often comes when an athlete loses control and ends up twisting or falling awkwardly. These unclean movements cause instability in the knee as it twists, which can tear the ACL. Contact in sports can cause the irregular movements, which is why athletes involved in running or tennis are at a lower risk than those who play basketball, football, or soccer.

What Are The Symptoms?

Symptoms of a torn ACL can range from an obvious popping sound to loss of motion, pain, and swelling. The pain is most noticeable right after the injury has occurred and the swelling will usually begin within a couple hours of injury. Perhaps the most unique symptom is a feeling of instability when you attempt to put weight on the knee. The knee will feel like it's going to collapse at any moment when attempting to walk.

How Are Torn ACLs Treated?

Unfortunately, a torn ACL typically doesn't heal well on its own, which means the treatment of a knee doctor in Renton, WA, is required, often with surgery. The reason surgery is usually recommended to repair the knee is that the knee is at much higher risk of being injured again when engaging in physical activity, despite cautious behavior. If the knee doesn't heal properly, long-term damage can occur. Most cases require the doctor to repair the ACL with a tendon graft because it's a highly successful procedure. This surgery, along with rest and physical therapy makes it possible for most people to return to an active lifestyle within eight to twelve months.
