ACL Injuries

Expert ACL Injury Treatment in South West Sydney & The Mid North Coast

An ACL injury often requires surgical reconstruction to restore knee stability, especially for active patients. As a knee subspecialist, Dr Richard Allom uses advanced arthroscopic techniques to help patients return to sport and prevent long-term joint damage.

Specialist Diagnosis

Dr Allom uses a thorough physical examination, including clinical tests like the Lachman test, and high-quality MRI scans to confirm the ACL tear and check for other common injuries, like a meniscal tear.

Stability Focus

The primary goal is restoring knee stability for active patients. Dr Allom performs arthroscopic reconstruction, typically using a hamstring tendon graft, to rebuild the ligament and protect the joint.

Personalised Care

Not every tear needs surgery. Your treatment plan will be tailored to your specific injury, your age, your lifestyle, and your activity goals.

Understanding ACL Injuries

That pop you felt in your knee during the game. The rapid swelling. That sickening instability. You might have torn your ACL.

This is one of the most common sports injuries, and it’s normal to worry about whether you'll play again. As a fellowship-trained knee subspecialist with extensive experience managing ACL injuries, Dr Richard Allom provides expert assessment and evidence-based treatment recommendations. When surgery is needed, he uses advanced arthroscopic reconstruction techniques designed to restore knee stability and help you return to the activities you love. While not all ACL tears require surgery, all require an expert assessment to determine the right pathway for you.

What is the ACL

Inside your knee, you have four major ligaments that keep it stable.

The anterior cruciate ligament (ACL) sits in the centre, connecting your thigh bone (femur) to your shin bone (tibia). Think of it as your knee's main stabiliser for pivoting. Its job is to prevent your shin bone from sliding too far forward on the thigh bone and to control the knee during twisting or cutting movements.

This is why it is so essential for sports like football, netball, basketball, and skiing.

Types of ACL Injuries

ACL injuries are graded based on how severe the tear is:

Grade I (Mild Sprain)

The ligament is stretched but not torn. This is uncommon.

Grade II (Partial Tear)

The ligament is partially torn. This is also uncommon, as many partial tears eventually become complete tears.

Grade III (Complete Tear)

The ligament is completely torn. This is the most common type of ACL injury and results in significant knee instability. It often requires surgical reconstruction for active people who want to return to pivoting sports.

ACL Tear

Symptoms

If you have torn your ACL, you most likely experienced several key symptoms at the time of the injury:
  • A loud 'pop' or snapping sound
  • Immediate and significant swelling that develops over a few hours
  • Severe pain, although this can sometimes fade
  • A feeling of instability, as if your knee is 'giving way' or buckling
  • Difficulty putting weight on your leg or a loss of full movement

Diagnosis

To determine if you have an ACL tear, Dr Allom will start by discussing your symptoms and how the injury happened. He will then conduct a careful physical examination at one of his clinics in South West Sydney (Campbelltown, Liverpool, Gledswood Hills) or the Mid North Coast (Taree, Forster).

This involves specific tests, like the Lachman test, to check the stability of your knee. To get a clear picture of the injury, he will refer you for an MRI scan. This is the best way to see the soft tissues inside your knee, confirm the ACL tear, and check for other common injuries like a meniscal tear or cartilage damage. You might also have an X-ray to make sure there are no injuries to the bone, like a fracture.

Treatment Options

Dr Allom creates a treatment plan based on your specific needs. He will consider the type of tear, your age, your activity level, and your personal goals. Not all ACL tears require surgery.

Non-Surgical Treatment

This approach may be suitable if you are older, have lower activity demands, or do not participate in pivoting sports. It involves a structured physiotherapy programme to restore motion, strength, and function. However, for active individuals, non-surgical management carries a high risk of ongoing instability. This instability can lead to secondary damage, such as meniscal tears and the early onset of osteoarthritis.

Surgical Treatment

Surgery is the recommended solution for active patients who want to return to pivoting sports (like netball, football, or skiing) or those who experience recurrent instability in daily life. The goal of surgery is to restore stability, which in turn protects your knee from further damage and allows you to return to your activities.

Arthroscopic ACL Reconstruction

Dr Allom performs ACL reconstruction using an arthroscope, which is a minimally invasive keyhole technique. The procedure involves rebuilding the torn ligament using a new one, called a graft.
  • In most cases, this graft is taken from your own hamstring tendons, which are located at the back of your thigh.
  • Dr Allom places this new graft in the exact anatomical position of your old ACL to restore your knee's stability and natural function.
  • If you also have a repairable meniscal tear, which is a very common associated injury, he will fix that at the same time.

Surgery and Recovery

ACL reconstruction is usually performed as a day procedure, meaning you can go home the same day. Recovery is a comprehensive process that requires a significant commitment to physiotherapy. While you can often return to light activities in a few months, returning to sport takes longer. Most athletes aim to return to their competitive sport within 9 to 12 months. This timeline depends on you successfully passing specific strength and functional tests to ensure your knee is ready and to reduce the risk of re-injury.

Dr Allom's Approach to Meniscal Tears

As a fellowship-trained knee subspecialist, Dr Allom provides complete ACL injury management, from initial diagnosis through to surgical reconstruction and rehabilitation. His subspecialist training means he is skilled in the latest arthroscopic techniques. His expertise is further supported by a Master's Degree in Surgery. He is dedicated to creating an individualised treatment plan based on your age, activity level, and personal goals. He takes the time to clearly explain your diagnosis and options so you can feel confident about your care.

"Look, I'm not here to push you toward surgery if you don't need it. Some of my patients do brilliantly without reconstruction. They modify activities, commit to rehab, and they're fine. But if you're 28 and you play competitive netball? We need to have a serious conversation about surgery, because without it, your knee will keep giving way and you'll likely tear your meniscus within a few years. I base my recommendation on what you want your life to look like. This depends on your age, your sport, your work demands, and what other injuries we find on your MRI. There's no one-size-fits-all answer here."

Frequently Asked Questions

Unlike some other ligaments, the ACL has a very poor blood supply and does not heal on its own once it has a complete tear. Conservative management involves learning to function with the torn ligament, not waiting for it to heal.

You will likely benefit from surgery if you want to return to sports that involve pivoting, cutting, or sudden stops (like football, netball, or skiing). It is also recommended if you experience recurrent instability during your daily activities, or if you have other associated injuries like a meniscal tear that needs repair.

For active individuals, untreated ACL deficiency carries significant risks. These include recurrent instability (giving way), a high risk of secondary meniscal tears (up to 40-50% within 5 years), and a much higher risk of developing early-onset osteoarthritis.

You can often delay ACL reconstruction for several weeks or even a few months without a negative impact. This allows time for the initial swelling to settle, for you to regain your full range of motion, and to properly consider your options. However, prolonged delays (over 6-12 months) while experiencing ongoing instability can increase your risk of secondary cartilage and meniscal damage.

After tearing one ACL, you have a 10-15% risk of tearing the ACL in your opposite knee. This risk is highest in the first two years after you return to sport. This is due to underlying risk factors and compensation patterns.

An ACL injury unfortunately increases your long-term risk of developing osteoarthritis in that knee, regardless of whether you have surgery or not. However, surgery to restore stability significantly reduces this risk compared to leaving the knee unstable. An unstable knee that suffers from recurrent giving-way episodes and secondary meniscal tears will develop arthritis much faster.

Next Steps

If you are dealing with knee instability or think you may have torn your ACL, a specialist assessment is the right next step.

What to Bring: Please bring your referral letter, all relevant imaging studies (X-rays, CT scans, MRI if performed), and your list of current medications to your consultation.
