ACL Surgery Physiotherapy in Singapore
ACL surgery helps restore knee stability after a ligament tear, but full recovery depends on proper rehabilitation. At ACE Physio Sports in Singapore, we guide you through every stage to regain strength, movement, and confidence.


What is ACL Surgery?
ACL (Anterior Cruciate Ligament) surgery is performed to repair or reconstruct a torn ligament in the knee that is essential for stability.
The ACL plays a key role in controlling knee movement. When it is torn, patients often experience:
- Knee giving way during walking or turning
- Difficulty bearing weight
- Instability during sports
ACL reconstruction replaces the damaged ligament using a graft, helping restore knee stability and function.
If you are looking for ACL rehabilitation physiotherapy in Singapore, ACE Physio Sports provides structured, expert-led recovery programmes.
Why is ACL Surgery Needed?
Surgery is recommended when knee instability affects daily life or sports.
Common reasons include:
- Complete ACL tear
- Knee keeps giving way during activity
- Inability to return to sports
- Repeated knee injuries
- Risk of further damage (meniscus or cartilage)
Patients often say:
- “My knee feels unstable when I walk”
- “I cannot pivot or turn properly”
- “My knee buckles suddenly”
Physiotherapy BEFORE ACL Surgery
Pre-surgery physiotherapy (prehabilitation) improves recovery outcomes significantly.
At ACE Physio Sports, we focus on:
- Reducing swelling and pain
- Restoring full knee movement
- Improving muscle strength (quadriceps, hamstrings)
- Achieving near-normal walking
This ensures your knee is in the best condition before surgery, leading to faster recovery.
Symptoms After ACL Surgery
After surgery, it is normal to experience:
- Pain and swelling in the knee
- Stiffness and reduced movement
- Muscle weakness
- Difficulty walking
- Reduced balance and control
Patients often ask:
- “Why can’t I bend my knee properly after surgery?”
- “My knee feels weak and unstable after ACL surgery”
- “When can I walk normally again?”
These symptoms improve with proper rehabilitation.

Recovery Timeline & Long-Term Outcomes
Typical recovery timeline:

Frequently Asked Questions
Do I need surgery for a Anterior Cruciate Ligament (ACL)?
Most ligament injuries — including partial tears — heal well with physiotherapy alone. Surgery is usually reserved for complete ruptures in high-demand athletes or cases where conservative treatment fails. A physiotherapy assessment can determine the severity and guide the right approach.
My knee feels very unstable after the injury — is that normal?
Yes — a feeling of instability or "giving way" is common after a ligament injury because the damaged ligament can no longer provide full joint support. Physiotherapy rebuilds stability through targeted strengthening and proprioception (balance awareness) training.
How long until I can return to sport after a Anterior Cruciate Ligament (ACL)?
Timelines depend on severity: mild sprains may resolve in 2–4 weeks, while complete tears requiring surgery can take 6–12 months. Your physiotherapist will use functional tests and strength assessments to confirm you're truly ready before clearing you for full activity.
