Anterior Cruciate Ligament (ACL) Injury: What You Need to Know

An ACL injury is one of the most common serious knee injuries, particularly in sports that involve sudden changes of direction, jumping or pivoting. Whether you’ve experienced an ACL tear while playing football, netball, basketball, soccer or skiing, early assessment and appropriate rehabilitation are important for your recovery.

At Belconnen Physiotherapy Clinic in Canberra, we help people recover from ACL injuries through evidence-based physiotherapy, whether they are managing their injury without surgery or recovering following ACL reconstruction. Every rehabilitation program is tailored to the individual’s goals, activity level and clinical presentation.

What Is the Anterior Cruciate Ligament?

The anterior cruciate ligament (ACL) is one of the major ligaments inside the knee. It connects the thigh bone (femur) to the shin bone (tibia) and helps control forward movement and rotational stability of the knee.

When the ACL is injured, the knee may become unstable, making activities such as turning, pivoting or landing from a jump more difficult.

How Does an ACL Injury Occur?

Most ACL injuries occur without direct contact. Common mechanisms include:

·Sudden changes of direction

·Landing awkwardly after jumping

·Rapid deceleration while running

·Pivoting on a planted foot

·Direct impact during contact sports

People often report hearing or feeling a “pop” at the time of injury, followed by rapid swelling and difficulty continuing activity.

Common Symptoms of an ACL Tear

Symptoms vary depending on the severity of the injury but commonly include:

·Sudden knee pain

·A popping sensation during injury

·Rapid swelling within several hours

·Difficulty bearing weight

·Knee instability or “giving way”

·Reduced range of motion

·Ongoing weakness during sporting activities

If you experience these symptoms following a knee injury, it is important to seek assessment from a qualified healthcare professional.

How Is an ACL Injury Diagnosed?

A physiotherapist will begin with a detailed discussion about how the injury occurred and perform a comprehensive physical examination of your knee.

Depending on your presentation, your GP or specialist may recommend imaging such as an MRI scan to confirm an ACL tear and identify any associated injuries, including damage to the meniscus or cartilage.

An accurate diagnosis helps guide the most appropriate management plan.

Do All ACL Tears Need Surgery?

No. Not every ACL injury requires ACL reconstruction.

Management depends on several factors, including:

·Your age

·Activity level

·Sporting goals

·Degree of knee instability

·Associated knee injuries

·Personal preferences

Some people successfully manage their ACL injury through structured physiotherapy and rehabilitation alone, while others may be advised to consider surgery after discussion with their orthopaedic surgeon.

Your physiotherapist can work alongside your GP and surgeon to help determine the most suitable pathway for your situation.

Physiotherapy for ACL Injury

Physiotherapy plays an important role both before and after surgery, as well as for people choosing non-surgical management.

Rehabilitation may include:

Reducing Pain and Swelling

Early treatment aims to improve comfort, reduce swelling and restore knee movement.

Restoring Strength

Exercises target the quadriceps, hamstrings, gluteal muscles and calf muscles to improve knee support and function.

Improving Balance and Control

Balance and neuromuscular exercises help retrain movement patterns and improve confidence during daily activities and sport.

Return to Running and Sport

For people returning to sport, rehabilitation progresses through carefully monitored stages based on strength, function and individual goals.

Every rehabilitation program is progressed according to your recovery rather than a fixed timeline.

Frequently Asked Questions About ACL Injuries

How long does an ACL injury take to recover?

Recovery varies considerably depending on the severity of the injury, whether surgery is performed, individual healing and rehabilitation progress. Your physiotherapist can provide guidance based on your specific circumstances.

Can I walk after an ACL tear?

Many people can still walk after an ACL tear, although the knee may feel unstable, swollen or painful. Walking does not necessarily rule out a significant ligament injury.

Can physiotherapy help without surgery?

Yes. Many people benefit from physiotherapy regardless of whether surgery is part of their management. Rehabilitation aims to improve strength, stability, movement and confidence while helping you return to your desired activities where appropriate.

When should I see a physiotherapist?

It’s advisable to arrange an assessment soon after a knee injury, particularly if you experience swelling, instability, difficulty walking or ongoing knee pain.
