ACL Injury Symptoms and Treatments – Orthopedic Los Angeles


ACL Injury & How to Treat It

The ACL can be injured when the knee joint is twisted, bent backwards, or bent unnaturally to the side. The likelihood of injury is greater if more than one of these movements occurs at the same time. ACL injury can also be caused by forceful contact, such as being hit by another person or object. In such an incident, it is very possible for other knee ligaments, cartilage such as the menisci, bones in the knee joint, or other parts of the knee to be injured as well.

Without proper treatment, an injured ACL has a decreased ability to control knee movement. A damaged ACL also makes it more likely for the knee bones to rub against each other. This is known as chronic ACL deficiency. The abnormal bone movement can also damage the cartilage that covers the ends of the bones, and can trap and tear the menisci that cushion the knee joint. This damage can subsequently lead to osteoarthritis. These complications can be avoided by promptly getting the help of a Knee Specialist like our doctors to make sure your knee heals properly.


  • kerlan jobe orthopedic clinic ronald kvitne shoulder knee orthopedic specialistAt the time of injury there is a pop in the knee that can be felt or even heard.
  • Pain on the outside and back of the knee.
  • Swelling of the knee within the first few hours of the injury. This may be caused by internal bleeding within the knee joint. Sudden swelling is usually a sign of serious injury.
  • Limited knee mobility due to pain, swelling or both.
  • Instability and weakness of the knee.

Our specialist can assess if you have an ACL injury by asking questions about your past health and examining your knee. Our specialist may ask about the circumstances that led to your injury as well as if you had any other knee injuries in the past. Our specialist will check for stability, movement and tenderness in the injured knee, and compare it to the uninjured knee.

X-rays or other imaging tests may be required to determine the extent of the damage. X-rays can be used to check for damage to the knee bones. An MRI can show damage to ligaments, tendons, muscles and knee cartilage. It is also possible that a minimally invasive surgery technique, called arthroscopy, may be the wisest method of determining the extent of damage. During arthroscopy, a small camera and surgical tools are inserted through one or more small incisions in the knee in order to view the inside of the knee.


Begin first aid immediately. Use the RICE method. RICE is an abbreviation for Rest, Ice, Compression and Elevate. First rest the knee. Then put ice or a cold compress on it. Apply gentle compression on the knee by wrapping it with an elastic bandage. Elevate the leg by propping it above the level of the heart. It is also important to immobilize the leg and move it as little as possible.

These first-aid tips will help reduce swelling and pain. Over-the-counter pain medicine can also be taken to alleviate the pain.

For the first few days after the injury, you may need to walk with crutches and use a knee immobilizer.

Schedule an appointment and have your knee checked by our doctors. It is very important to get treatment. Without proper treatment the injury may become a long-lasting problem.

There are two ways to treat an ACL injury: through surgery or rehab.
Physical rehabilitation through exercises and training can take several months for the knee to get better. Our specialist does his best to avoid surgical intervention because many knee injuries can be successfully treated through conservative measures such as medication and rehabilitation therapy.

But if the knee injury is too severe, surgery is necessary. Our physicians are Orthopedic Surgeons specializing in minimally invasive, arthroscopic surgery. So, if you have an injury that requires surgery, you can rest assured that you are in good hands with the Avalon Orthopedic Surgeons.

For some people rehab is enough. For others, surgery is the way to go. Whatever the case, our specialists will help you determine the best course of treatment for your injury.
