An anterior cruciate ligament, or ACL, tear can significantly compromise knee stability and make even simple
movements such as walking, turning or climbing stairs feel uncertain. Many individuals also experience swelling,
pain and a sensation of the knee giving way, particularly during pivoting or weight bearing activities.
When structured rehabilitation is insufficient, ACL reconstruction surgery may be considered to repair
persistent instability, restore daily function and support a safe return to physical activity.

ACL surgery, also known as ACL reconstruction, is performed to restore stability to a knee with a torn anterior
cruciate ligament. The procedure involves replacing the damaged ligament with a tissue graft that acts as a new
stabilising structure.
The graft used for reconstruction may come from one of two sources:
The choice of graft depends on factors such as activity level, age and overall knee condition. The surgical procedure is fully discussed during consultation with an orthopaedic specialist.

An ACL tear cannot heal on its own due to limited blood supply. While structured rehabilitation and physical
therapy may allow some individuals to manage everyday activities, it does not restore ligament stability. A
damaged ACL may lead to persistent issues with stability, causing an adverse effect on daily life.
ACL reconstruction may be recommended when:
Consult our knee pain clinic to determine if ACL surgery is right for you.
A typical ACL reconstruction takes about 1–2 hours and is often performed as a day procedure or with a short hospital stay.
Recovery after ACL reconstruction follows a structured rehabilitation program focused on restoring knee strength, stability and function.
Throughout recovery, regular guidance from a physiotherapist supports safe progression. Adhering to the rehabilitation plan helps optimise outcomes and reduce the risk of re-injury.

ACL reconstruction is generally safe, but as with any surgery, some risks may occur. These are uncommon and carefully managed.
Possible risks include:
A comprehensive consultation with an orthopaedic specialist allows you to carefully balance the potential risks and benefits, while ensuring appropriate planning to reduce the likelihood of complications.
