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:
- Clinical assessment (with imaging to confirm diagnosis)
- Initial rehabilitation and swelling control
- Decision between non-surgical vs surgical management
- Structured physiotherapy for recovery
- 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
- Sudden twisting movements
- Pivoting sports
- Jumping and landing injuries
- Contact sports
- Poor landing mechanics
- Muscle imbalance
- Weak stabilizing muscles
- Fatigue-related injury
- Previous knee injury
- 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:
- Accurate diagnosis (MRI when needed)
- Rehabilitation and strengthening
- Medication for symptom control
- Individualized decision on surgery
- 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.
