Knee Surgery in Singapore: ACL Reconstruction for a Safe Return to Play, By Dr Benjamin Ang
INTRODUCTION
A sudden twist, an awkward landing, or a sharp change in direction, this is how an ACL injury begins for many athletes and active individuals. While the initial pain may settle, the real challenge often comes later, when the knee no longer feels stable or trustworthy.
For those considering knee surgery in Singapore after an ACL tear, understanding the injury and the role of reconstruction is often the first step towards a safe return to activity. So, what exactly happens when the ACL is injured, and when does reconstruction become necessary?
WHY DOES AN ACL INJURY CAUSE KNEE INSTABILITY?
The Anterior Cruciate Ligament (ACL) is one of the main stabilisers of the knee. It controls forward movement and rotation, especially during sports that involve cutting, pivoting, or sudden stops.
When the ACL is torn, the knee may still feel manageable during straight-line walking. However, during more demanding movements, patients often experience:
- A feeling of the knee “giving way”
- Loss of confidence during sport
- Recurrent swelling or discomfort
Over time, repeated instability can place additional strain on the meniscus and cartilage.

IS SURGERY ALWAYS REQUIRED FOR AN ACL TEAR?
Not necessarily. Some individuals are able to cope with an ACL-deficient knee through physiotherapy alone, particularly if their activities are low-demand.
However, ACL reconstruction, a form of knee surgery commonly performed for active patients, may be considered when:
- The knee remains unstable despite rehabilitation
- The individual wishes to return to sports involving pivoting or jumping
- There are associated injuries to the meniscus or cartilage
- Recurrent instability affects daily life or work
The decision is highly individual and should be based on lifestyle, sporting goals, and knee function.
WHAT DOES ACL RECONSTRUCTION INVOLVE?
ACL reconstruction is a minimally invasive procedure performed arthroscopically. The torn ligament is replaced with a tendon graft, commonly taken from the patient’s own hamstring or quadriceps tendon. A cadaveric allograft is also an option. During the same procedure, any meniscus or cartilage injuries may also be addressed.
The aim of surgery is not only to restore stability but also to protect the knee from further damage. Modern techniques allow for precise graft placement and strong fixation, supporting a more predictable recovery and a safer return to sport.
HOW LONG DOES RECOVERY TAKE?
Recovery does not end with surgery. Rehabilitation is a crucial part of the process and focuses on restoring movement, strength, balance, and control.
Most patients return to sport between 9 and 12 months, depending on the sport, individual progress, and commitment to physiotherapy. A gradual, structured return is essential to reduce the risk of re-injury.
WHY ADDRESSING KNEE INSTABILITY MATTERS?
Leaving knee instability unaddressed can increase the risk of secondary injuries, including meniscus tears and early degenerative changes. Early assessment and appropriate treatment help preserve long-term knee health and performance.
