What is an ACL Injury?

Three bones meet to form your knee joint: your thigh bone (femur), shinbone (tibia), and kneecap (patella). Your kneecap sits in front of the joint to provide some protection. Bones are connected to other bones by ligaments. There are four primary ligaments in your knee. They act like strong ropes to hold the bones together and keep your knee stable.
An ACL (anterior cruciate ligament) injury is one of the most common and well-known orthopedic injuries. The ACL is a very important ligament because it prevents the tibia (shin bone) from sliding in front of the femur (thigh bone). The ACL stabilizes the knee while walking, running, jumping, and moving from side to side. The posterior collateral ligament is within the knee and prevents the femur from sliding off the anterior edge of the tibia and to prevent the tibia from displacing posterior (similar to the anterior cruciate ligament ) and is not as commonly injured.

Common Causes:

  • Suddenly changing directions
  • Suddenly stopping
  • Landing from a jump
  • Direct injury to the knee

Symptoms of an ACL Injury may include:

  • Pain
  • Swelling
  • Instability
  • Limited range of motion
  • Stiffness

If you are experiencing any of these symptoms immediately seek treatment by making an appointment with the Orthopedic Physicians Alaska (OPA) team of knee specialists.

When you arrive for your initial consultation, Orthopedic Physicians Alaska (OPA) team of knee specialists will evaluate your areas of concern, discuss your symptoms, and develop a customized and comprehensive treatment plan tailored to your unique needs. This evaluation is a necessary part of diagnosing your condition and providing the best possible care.

When diagnosing an ACL  injury, the OPA specialist will provide:

  • A medical, injury, and symptom history review
  • A physical examination
  • Multiple view x-rays or MRI

Common Treatments:

Nonsurgical treatment options are used to treat an ACL sprain or partial tear. The following may be included in a customized OPA treatment plan:

Nonsteroidal anti-inflammatory medications (NSAIDs)

Decrease inflammation and pain.

Physical Therapy

OPA approved physical therapist will provide exercises strengthen the ligament and surrounding muscles, ligaments and tendons.


A brace and crutches take the weight off the knee.

Activity Modification

Slowing down or stopping activities that caused the injury or cause symptom flare-ups.

Complete ligament tear usually requires surgical intervention. During a ligament repair, an OPA knee specialists remove the torn ligament and replace with hamstring tendons or a cadaver ligament. Physical therapy will be an important part of recovery after surgery.
