🦵 What is an Anterior Cruciate Ligament (ACL) Injury? Symptoms and Treatment Options

29/03/2026

The anterior cruciate ligament (ACL) is one of the key stabilizing ligaments of the knee. It plays a critical role in maintaining knee stability, especially during sudden movements and changes in direction. ACL injuries are most commonly seen in athletes, but they can also occur in everyday activities.

🧠 What is the ACL and What Does It Do?

The ACL:

  • Prevents the tibia from moving forward relative to the femur
  • Controls rotational stability of the knee
  • Stabilizes the joint during sudden movements

👉 In simple terms, it acts as the primary stabilizer of the knee

⚠️ How Do ACL Injuries Occur?

Common causes include:

  • Sudden changes in direction (pivoting)
  • Landing incorrectly after a jump
  • Twisting movements of the knee
  • Sports injuries (football, basketball, skiing)
  • Falls or traffic accidents

🚨 What Are the Symptoms?

ACL injuries often present with characteristic symptoms:

✔ A "popping" sound or sensation at the time of injury
✔ Rapid swelling within a few hours
✔ Knee instability or "giving way"
✔ Pain and difficulty walking
✔ Feeling of insecurity, especially when going downstairs

🩺 How is the Diagnosis Made?

The most important step is:

👉 Physical examination

Your doctor will assess the knee using:

  • Lachman test
  • Anterior drawer test
  • Pivot shift test

👉 MRI (Magnetic Resonance Imaging) is used to confirm the diagnosis and evaluate associated injuries.

🏥 Treatment Options

Treatment depends on several factors, and there is no single approach suitable for all patients.

🟢 Non-Surgical Treatment

May be appropriate for:

  • Patients with low activity levels
  • Older individuals
  • Patients without significant instability

Includes:

  • Physical therapy
  • Muscle strengthening
  • Activity modification
  • Knee bracing

🔴 Surgical Treatment (ACL Reconstruction)

Recommended for:

  • Active individuals
  • Athletes
  • Patients with knee instability

How is it performed?

  • The torn ligament is not repaired directly
  • A new ligament (graft) is created
  • The procedure is performed arthroscopically (minimally invasive)

⏳ Recovery After ACL Surgery

  • Day 1: Walking begins
  • 2–4 weeks: Return to daily activities
  • 3 months: Light sports activities
  • 6–9 months: Return to full sports

👉 The most critical factor is a well-structured rehabilitation program

⚠️ What Happens if It Is Not Treated?

Untreated ACL injuries may lead to:

  • Meniscus tears
  • Cartilage damage
  • Early knee osteoarthritis
