ACL Injury (Anterior Cruciate Ligament Tear) Treatment in Singapore: A Complete, Evidence-Based Care Pathway

Knee Instability After a Twist — Could It Be an ACL Injury?

The anterior cruciate ligament (ACL) helps stabilize the knee during movement.

ACL injuries commonly occur with:

  • Sudden twisting or pivoting
  • Sports involving cutting or jumping
  • Landing awkwardly

Typical symptoms include:

  • A “pop” sound at the time of injury
  • Immediate swelling
  • Knee instability or “giving way”
  • Difficulty returning to sports

Because ACL injuries can affect long-term knee stability, early structured management is important.


What Evidence-Based Guidelines Recommend

Clinical guidelines and orthopaedic consensus recommend a structured, individualized approach:

  1. Clinical assessment (with imaging to confirm diagnosis)
  2. Initial rehabilitation and swelling control
  3. Decision between non-surgical vs surgical management
  4. Structured physiotherapy for recovery
  5. Surgical referral when indicated

The Pain Relief Clinic aligns its care model with this pathway.


1. Diagnosis First: Confirming the ACL Injury

ACL injuries require accurate diagnosis to determine:

  • Partial vs complete tear
  • Associated injuries (meniscus, cartilage)
  • Knee stability

At The Pain Relief Clinic:

  • Clinical assessment is performed
  • MRI may be arranged within 1 working day when appropriate

This helps guide:

  • Whether surgery is needed
  • Or whether structured rehabilitation may be suitable

2. Physiotherapy & Rehabilitation: Essential for All Patients

Rehabilitation is important regardless of whether surgery is performed.

Active Rehabilitation

Programmes may include:

  • Quadriceps and hamstring strengthening
  • Balance and proprioception training
  • Knee stability exercises
  • Functional and sports-specific drills (progressively introduced)

These are tailored based on:

  • Injury severity
  • Activity goals
  • Stability of the knee

Passive Non-Invasive Support

To support recovery:

  • Shockwave therapy
  • Radiofrequency-based deep tissue therapy
  • Manual therapy where appropriate

These may help reduce discomfort and improve movement tolerance.

Integrated Physiotherapy (Key USP)

  • Physiotherapists are MOH AHPC-licensed
  • Rehabilitation is closely coordinated with the doctor
  • Programmes are adjusted based on imaging findings and progress

3. Medication: Supporting Early Recovery

Medication may be used to:

  • Reduce pain
  • Manage inflammation
  • Support early rehabilitation

First-Line Options

  • Paracetamol
  • Topical NSAIDs
  • Oral NSAIDs

Second-Line / Subsequent Options

  • COX-2 inhibitors
  • Short-term oral opioids (used cautiously)

Medication is:

  • Typically short-term
  • Used to support rehabilitation
  • Not intended as a standalone solution

4. Injection Options (Selected Cases)

Injection therapy is not the primary treatment for ACL tears but may be considered in specific situations.

Local Anaesthetic Injections

  • Temporary pain relief

Corticosteroid Injections

  • Used selectively if significant inflammation is present

PRP (Platelet-Rich Plasma)

  • Considered in selected cases
  • Evidence is evolving

Pulsed Radiofrequency

  • May be used for pain modulation in chronic cases

Viscosupplementation

  • Not typically used for ligament injuries

Injection therapy is generally:
👉 Adjunctive and not a replacement for rehabilitation or surgery when indicated


5. Integrated, Team-Based Care

ACL injury management requires coordination.

At The Pain Relief Clinic:

  • Care is led by Dr. Terence Tan, a licensed medical doctor (SMC)
  • With over 20 years of clinical experience
  • Working closely with in-house AHPC-licensed physiotherapists

Treatment plans are adjusted based on:

  • Diagnosis
  • Imaging findings
  • Stability of the knee
  • Functional goals

6. Non-Surgical vs Surgical Management

Not all ACL injuries require surgery.

Non-Surgical Approach May Be Suitable When:

  • Partial tear
  • Low-demand lifestyle
  • Good knee stability after rehabilitation

Surgical Reconstruction May Be Considered When:

  • Complete tear with instability
  • High-demand sports participation
  • Associated injuries (e.g., meniscus damage)

The decision is individualized based on patient needs.


7. When Is Surgery Considered?

Surgery may be recommended when:

  • Knee instability persists
  • Functional goals require stability (e.g., sports)
  • There are associated structural injuries

In such cases, The Pain Relief Clinic:

  • Provides assessment and MRI
  • Refers patients to orthopaedic specialist partners
  • Coordinates pre- and post-surgical rehabilitation

Common Causes of ACL Injury

  1. Sudden twisting movements
  2. Pivoting sports
  3. Jumping and landing injuries
  4. Contact sports
  5. Poor landing mechanics
  6. Muscle imbalance
  7. Weak stabilizing muscles
  8. Fatigue-related injury
  9. Previous knee injury
  10. Combined biomechanical factors

When Should You Seek a Structured Approach?

You may benefit from coordinated care if:

  • You felt a “pop” during injury
  • Knee swelling occurred quickly
  • The knee feels unstable
  • You want to return to sports
  • You are unsure whether surgery is needed

Final Takeaway

ACL injury management is best approached through a structured pathway:

  1. Accurate diagnosis (MRI when needed)
  2. Rehabilitation and strengthening
  3. Medication for symptom control
  4. Individualized decision on surgery
  5. Coordinated care before and after intervention

The Pain Relief Clinic provides these components in an integrated, coordinated, and evidence-aligned manner, supporting recovery and return to function.


FAQ

Q1: Do all ACL tears require surgery?
No. Some cases can be managed with rehabilitation depending on stability and activity level.

Q2: How long is recovery?
Recovery varies depending on treatment approach and goals.

Q3: Is MRI necessary?
MRI is typically used to confirm diagnosis and assess associated injuries.

Q4: Can I return to sports after ACL injury?
Return to sports depends on stability, rehabilitation, and treatment choice.
