ACL Tears

acl tear or injury adelaide

A common knee ligament injury that can affect stability, function, and performance

The anterior cruciate ligament (ACL) is one of the key ligaments that helps stabilise your knee joint. It connects the thigh bone (femur) to the shin bone (tibia) and plays an important role in controlling forward movement and rotation of the knee. An ACL tear is a common injury, especially among athletes and physically active individuals. It can occur during sudden stops, pivots, changes in direction, or direct impacts to the knee.

Dr George Awwad provides thorough assessment, diagnostic imaging, and tailored treatment for ACL tears, from conservative management to surgical reconstruction, depending on your activity level, lifestyle, and injury severity.

Signs and symptoms of an ACL tear

An ACL tear is typically associated with a noticeable injury event and may include the following symptoms:
While a complete ACL rupture often causes obvious symptoms, partial tears or associated injuries to other structures (e.g., meniscus, MCL) may also contribute to discomfort and loss of function.
  • A loud pop or “popping” sensation at the time of injury
  • Sudden onset of knee pain and swelling, usually within the first few hours
  • Instability or a feeling of the knee “giving way”, especially during turning or pivoting motions
  • Difficulty walking or bearing weight
  • Reduced range of motion and stiffness
  • Ongoing symptoms of instability or weakness during sport or daily activities

Causes and risk factors

ACL tears are most often associated with sporting activities that involve:

  • Sudden stops or changes in direction (e.g., soccer, netball, basketball)
  • Pivoting or twisting motions while the foot is planted
  • Landing awkwardly from a jump
  • Direct contact or trauma to the knee (e.g., during tackles)

Women are statistically more likely to sustain ACL injuries due to a combination of anatomical, hormonal, and biomechanical factors.

Diagnosing an ACL tear

Dr Awwad will begin with a detailed history and physical examination to assess your knee stability, swelling, and range of motion. Specific clinical tests such as the Lachman test and pivot shift test help assess the integrity of the ACL.

Imaging may include:

  • X-rays: Used to rule out fractures or associated bony injuries
  • MRI scan: The most accurate way to confirm a complete or partial tear and assess other internal knee injuries such as meniscal tears or bone bruising

A prompt and accurate diagnosis helps determine whether non-surgical or surgical treatment is most appropriate.

Treatment options for ACL injuries

Management depends on the severity of the injury, your age, activity level, and whether other knee structures are involved.

Non-surgical treatments

In some cases, particularly with partial tears or low-demand patients, a non-operative approach may be recommended. This can include:
  • Physiotherapy to improve strength, stability, and range of motion
  • Bracing to support the knee during activity
  • Activity modification to avoid instability and further injury.

Surgical treatment: ACL reconstruction

For active individuals or those experiencing knee instability, ACL reconstruction is often recommended. This procedure involves replacing the torn ligament with a graft, typically sourced from one of the following:
  • Hamstring tendon
  • Quadriceps tendon
  • Patellar tendon
  • Allograft (donor tissue, used in select cases)
Dr Awwad uses modern surgical techniques, including arthroscopic (keyhole) methods, to reconstruct the ligament with precision. The choice of graft is based on your anatomy, activity goals, and surgical preference.
