ACL Tears

The ACL is in the center of the knee.

It connects the anterior (front) tibia to the posterior (back) femur and is responsible for stability of the knee

Causes

Anterior cruciate ligament (ACL) injuries most commonly occur during sports and physical activities. Rapid changes in direction, sudden stops, or improper landing techniques can lead to an ACL tear. These movements place significant stress on the knee, increasing the risk of injury.

Signs and Symptoms of an ACL Tear

An ACL injury is often marked by a distinct "popping" sound at the moment of injury, followed by the sensation of the knee giving way or buckling. Additional symptoms include:

  • Pain accompanied by swelling around the knee
  • Reduced ability to fully straighten or bend the knee
  • Tenderness along the joint line
  • Discomfort or instability during walking

How We Diagnose ACL Injuries

At OrthoSouth, we begin with a comprehensive evaluation of your symptoms and medical history. Our orthopedic specialists conduct a detailed physical examination, comparing your injured knee to the healthy one to assess differences in appearance, stability, and range of motion. While many ACL injuries can be diagnosed through this exam, we may also use advanced imaging techniques such as X-rays or MRI scans to rule out other injuries and gain a clearer view of the knee joint.

Effective Treatment Options for ACL Tears

Treatment for ACL injuries at OrthoSouth is personalized based on your specific condition, activity level, and goals. Non-surgical options include targeted physical therapy and rehabilitation programs designed to restore knee strength, flexibility, and function. For more severe tears, surgical repair may be recommended. This procedure involves reconstructing the torn ligament using a tendon graft to restore stability and support to the knee. Our expert physicians guide you through every step of the recovery process to help you return to your active lifestyle safely and confidently.
