Anterior Cruciate Ligament (ACL) Tears and Treatment Options

In sports injuries, few are as notorious and debilitating as an anterior cruciate ligament (ACL) tear. Whether you're an athlete or a fitness enthusiast, an ACL tear can bring your active lifestyle to a screeching halt.

However, understanding the causes, symptoms, treatment of ACL injuries, and recovery strategies can pave the way for a successful return to form.

What are the causes and symptoms of ACL tears?

The anterior cruciate ligament, one of the four major ligaments in the knee, plays a crucial role in stabilizing the joint during movement.

ACL tears commonly occur during sports involving sudden stops, direction changes, or direct impact on the knee. Basketball, soccer, football, and skiing are among the activities most associated with ACL injuries.

The symptoms of an ACL injury can vary depending on the severity of the injury, but common signs include:

  • A popping sensation in the knee at the time of injury.

  • Severe pain and swelling

  • Bruising

  • Discomfort or difficulty walking

  • Instability of the knee

  • Difficulty bearing weight

  • Limited range of motion

Some individuals may experience a "painless" ACL tear, particularly if other structures in the knee are also injured simultaneously. That's why it's important to seek prompt medical evaluation if you suspect an ACL injury.

How are ACL tears diagnosed?

Prompt diagnosis of an anterior cruciate ligament tear is critical for determining the appropriate course of action. ACL tears are typically diagnosed through a combination of the following:

  • A thorough medical history.

  • Physical examination of the knee through palpation, Lachman test, anterior drawer test, and pivot shift test.

  • Imaging tests, such as X-rays and MRIs, to confirm the diagnosis and evaluate the extent of the injury.

  • Additional tests like ultrasound and arthroscopy.

Delaying diagnosis or treatment can lead to complications such as cartilage damage, meniscus tears, and long-term instability of the knee joint.

What are the different treatment options for ACL tears?

Once diagnosed, the treatment approach for an ACL tear depends on various factors, including the severity of the injury, the individual's activity level, and their overall health.

Non-surgical treatment

For less severe ACL tears or for individuals who are less active or prefer to avoid surgery, non-surgical treatment options may be considered. This approach often involves a combination of the following:

  • Rest

  • RICE therapy

  • Medications

  • Physical therapy

  • Bracing

While non-surgical treatment of ACL injuries may not fully restore its function, it can help manage symptoms and support a return to daily activities.

Surgical treatment

Surgery may not be necessary for everyone with an anterior cruciate ligament injury. However, it is typically recommended for individuals who:

  • Are active and participate in sports or activities that require stability and agility.

  • Have experienced significant instability in the knee, especially during daily activities or sports.

  • Have concurrent injuries or damage to other structures within the knee joint, such as meniscal tears or ligamentous injuries.

  • Desire to return to high-demand activities or sports that place increased stress on the knee.

Common surgical procedures for anterior cruciate ligament reconstruction include autograft reconstruction and allograft reconstruction.

ACL reconstruction surgery involves replacing the torn ligament with a graft, typically from the patient's hamstring tendon or a cadaver donor. This procedure aims to restore knee stability and prevent further damage to the joint.

What does rehabilitation involve post-ACL surgery?

Rehabilitation following anterior cruciate ligament treatment is a comprehensive process aimed at restoring strength, mobility, stability, and function to the knee joint. The rehabilitation program is typically overseen by a physical therapist and progresses through several phases:

Early rehabilitation

After treatment of ACL injuries through surgery, individuals are usually advised to use crutches and wear a knee brace to protect the knee and promote healing. Pain management and swelling reduction are also prioritized during this phase.

Physical therapy begins soon after surgery to restore range of motion, strengthen the surrounding muscles, and regain functional mobility.

Initially, exercises focus on gentle movements and isometric muscle contractions to prevent stiffness and muscle atrophy.

Intermediate rehabilitation (6-12 weeks)

Emphasizes progressive strengthening of the quadriceps, hamstrings, hip muscles, and core stabilizers to improve knee stability and function. Exercises may include:

  • Closed-chain exercises (e.g., leg press, squats)

  • Open-chain exercises (e.g., hamstring curls, leg extensions)

  • Functional movements to enhance neuromuscular control and proprioception.

Advanced rehabilitation (12 weeks and beyond)

By this stage, individuals are typically transitioning back to sport-specific training and activities. Physical therapy continues to focus on improving strength, endurance, and agility while gradually increasing the intensity and complexity of exercises.

Full return to sports usually occurs around 6-9 months post-surgery, although it may take up to a year for some individuals to regain full confidence and performance levels.

How can you prevent ACL tears?

While ACL tears are often unavoidable, certain measures can help reduce the risk of sustaining such injuries:

  • Proper warm-up and stretching: Always warm up before engaging in physical activity, and incorporate dynamic stretching to prepare the muscles and joints for movement.

  • Strength training: Focus on building strength in the muscles surrounding the knee, particularly the quadriceps, hamstrings, and calves, to provide better support and stability to the joint.

  • Technique and form: Learn and practice proper techniques for sports and activities to minimize the risk of awkward movements or sudden changes in direction that could lead to injury.

  • Use protective gear: Wear appropriate protective gear, such as knee braces or padding, especially during high-risk activities or sports with a high incidence of ACL injuries.

  • Cross-training: Incorporate a variety of activities into your fitness routine to avoid overuse injuries and maintain overall strength and flexibility.
