MCL & PCL Surgery in Singapore

If your knee gives way during pivoting or feels unstable after an injury, you might have a medial collateral ligament (MCL) or posterior cruciate ligament (PCL) tear. Knowing when to opt for conservative treatment versus surgery is key to recovery.

UNDERSTANDING THE INJURY

Understanding MCL & PCL Injuries: Diagnosis and Severity

The MCL and PCL represent two distinct ligament structures with different healing capacities and surgical requirements. Proper diagnosis through clinical examination and imaging determines whether you need surgery or can recover through conservative management.

The Anatomy of a Knee Ligament Tear: MCL vs. PCL

The knee joint is stabilised by four main ligaments, each serving a unique biomechanical purpose. The Medial Collateral Ligament (MCL) is located on the inner side of your knee. Its primary role is to prevent the knee from collapsing inward (valgus stress). Because the MCL sits outside the main knee capsule and has a good blood supply, even severe tears often heal well without an operation.

In contrast, the Posterior Cruciate Ligament (PCL) is located deep at the back of the knee joint. It is the strongest of the cruciate ligaments, chiefly responsible for stopping the shinbone (tibia) from sliding too far backward relative to the thigh bone (femur). Due to its deep location and lower blood flow, a complete PCL tear is less likely to heal spontaneously.

Grading the Severity: When is a Tear Considered High-Grade?

Ligament injuries are classified based on the extent of the damage, which directly dictates the treatment route. This grading system is vital for determining the necessity of MCL & PCL Surgery in Singapore:

  • Grade 1: A minor stretch or sprain; the ligament is intact, and the knee is stable.
  • Grade 2: A partial tear; there is some looseness in the joint, but the ligament still provides some stability.
  • Grade 3: A complete rupture (full tear) where the ligament is torn into two separate pieces, leading to significant instability in the knee.

 

For most isolated MCL injuries, non-operative management works, but a Grade 3 tear that fails to stabilise with conservative care is a strong indication for surgical intervention. For the PCL, high-grade tears causing ongoing instability are frequently considered for reconstruction.

Accurate Diagnosis: Why an MRI Scan is Essential in Singapore

A precise diagnosis requires more than just a physical check. After an initial consultation, which involves stability testing (like the valgus stress test for MCL or posterior drawer test for PCL), imaging is crucial.

An MRI scan serves as the standard for visualising soft tissue injuries in the knee. This non-invasive imaging technique reveals:

  • The precise location and grade of MCL or PCL tears
  • Damage to other ligaments (ACL, lateral collateral ligament, posterolateral corner)
  • Meniscus tears that frequently accompany ligament injuries
  • Cartilage damage or bone bruising
  • Fluid accumulation within the joint

 

In Singapore’s healthcare system, MRI scans are readily available at both public and private facilities. The comprehensive information provided by an MRI enables your surgeon to develop an accurate treatment plan and helps you understand the full extent of your injury.

TREATMENT PATHWAY

Non-Surgical vs. Surgical Treatment

Not every MCL or PCL tear requires an operation. In fact, most isolated MCL injuries and many PCL tears respond well to conservative treatment. The decision between surgical and non-surgical management depends on multiple factors: tear severity, knee stability, associated injuries, your activity level, and how your knee responds to initial rehabilitation efforts

Non-Surgical Treatment for MCL and PCL Tears (Conservative Management)

Many patients can avoid an operation. The non-surgical route focuses on protecting the ligament while the body attempts to heal itself. This is the standard of care for most Grade 1 and Grade 2 MCL tears, and many isolated Grade 1 or 2 PCL tears.

  • R.I.C.E. Protocol: Rest, Ice, Compression, and Elevation are crucial immediately following the injury to control swelling and pain.

  • Bracing and Immobilisation: A prescribed hinged knee brace locks the knee in an optimal position, protecting the healing ligament from harmful stresses while allowing controlled, gentle motion to prevent stiffness.

  • Physical Therapy: This is the cornerstone of non-operative success. Physiotherapy focuses on aggressively strengthening the muscles surrounding the knee (quadriceps and hamstrings) to compensate for the temporarily lax ligament, thus restoring dynamic stability.

 

For less severe tears managed conservatively, recovery can often see patients return to dai

Key Indicators for MCL & PCL Surgery in Singapore

Surgery moves from being an option to a recommendation when non-operative management fails to secure the knee joint. We carefully consider several factors before proceeding with MCL & PCL Surgery in Singapore:

  • Multi-ligament injuries: This is the most common reason for surgery. When the MCL is torn along with the PCL, ACL, or posterolateral corner, the sheer instability requires extensive surgical stabilisation.
  • Chronic Instability: If a patient continues to experience a sensation of the knee “giving way” or buckling during walking or turning, even after 3 to 6 months of rigorous physical therapy, surgery is indicated to restore mechanical stability.

  • Avulsion Fractures: If the ligament is not simply torn mid-substance but has pulled a small fragment of bone away from where it attaches to the femur or tibia, surgical reattachment (fixation) is usually required to provide a rigid anchor for healing.

  • High-Grade Isolated Tears: While rare for the MCL, a complete PCL tear causing significant backward sliding of the tibia will almost always require PCL reconstruction for athletes or those with high functional demands.

Multi-Ligament Knee Injuries: Complex Reconstruction

When the PCL and MCL are both damaged, the operation becomes a high-level, intricate procedure. 

These multi-ligament knee injuries demand a specialist approach. The surgeon must map out a comprehensive staged approach to address all damaged structures meticulously, ensuring the reconstructed ligaments are placed correctly to restore the knee’s natural biomechanics. This level of surgery often requires longer immobilisation and a more prolonged, intensive rehabilitation schedule to support the healing of multiple repaired or reconstructed tissues simultaneously.

The Surgical Procedures: Repair vs. Reconstruction Techniques

When surgery is deemed necessary, the technique employed is highly specific to the injured ligament and the nature of the tear. Understanding the difference between repair and reconstruction is key to setting recovery expectations.

Posterior Cruciate Ligament (PCL) Reconstruction

Because the PCL is deep within the joint and subjected to high posterior loads, surgery to fix it is nearly always a reconstruction.

  • Grafting is the Standard: A tendon graft (autograft or from a donor, allograft) is used to create a new PCL.

  • Arthroscopic Technique: This procedure is typically performed using arthroscopy (minimally invasive, keyhole surgery). The surgeon drills tunnels into the thigh bone (femur) and shin bone (tibia) to pass the new graft through. The graft is then secured with modern fixation devices like screws or buttons to ensure it holds firmly while it matures into a functioning ligament. This minimally invasive approach generally leads to less pain and smaller scars compared to older, open techniques.

Medial Collateral Ligament (MCL) Surgical Repair and Reconstruction

For the MCL, the surgeon has two main tools:

  • MCL Repair: This is the preferred option if the tear is acute and located near the ligament’s attachment point on the bone. The surgeon meticulously stitches the torn ends back together, often using strong, internal splinting tapes or sutures to reinforce the repair while it heals back onto the bone.

  • MCL Reconstruction: This technique is reserved for chronic tears, tears that are too frayed to be repaired, or when the tear is in the middle of the ligament body. Here, a new MCL is created using a graft, often sourced from the patient’s own hamstring or patellar tendon (autograft). This is a more involved procedure but offers a robust, long-term solution for stability.

Recovery Timeline and Rehabilitation: A Structured Approach

The surgery is only the halfway point; the success of your knee stability hinges entirely on your commitment to the often long and disciplined rehabilitation phase. Healing ligament tissue needs time and specific loading to become strong.

Post-Operative Care: Brace, Weight-Bearing, and Early Exercises

The initial weeks post-surgery (Weeks 0-6) are all about protection. You will be on crutches, and your knee will be in a locked brace to prevent any backward movement that could stretch the healing graft. Weight-bearing status is determined by the surgeon based on the complexity of the repair; it might be restricted initially. Early in this phase, gentle exercises like quadriceps sets and ankle pumps are encouraged immediately to maintain muscle activation and circulation, even while the knee is immobilised. It is paramount to follow your surgeon’s exact instructions regarding the brace and crutch use to avoid graft failure.

Phases of Intensive Physical Therapy and Return to Activity

After the initial protection phase, typically around the six-week mark, you transition into intensive physiotherapy. This is where the real work begins to restore function.

  • Intermediate Phase (Weeks 6-12): Focus shifts to carefully increasing the range of motion (ROM) and beginning strength training for the major leg muscles.
  • Advanced Phase (Months 3-6): Strength and functional activities like stationary cycling or swimming are introduced. The goal is often to reach 80% strength compared to the uninjured leg.

  • Return to Activity Phase (Months 6-12+): This final stage involves a gradual reintroduction of sport-specific drills, cutting, pivoting, and impact activities. While you might feel functional stability within 6 months, achieving a return to full competitive sport often requires 9 to 12 months to ensure the reconstructed ligament has adequately matured and integrated.

The Cost of MCL & PCL Surgery in Singapore

Understanding the financial aspects of knee ligament surgery helps you plan appropriately and explore available funding options. Singapore’s healthcare system offers multiple pathways to access quality surgical care whilst managing costs effectively.

Getting a diagnosis in the private system involves a few initial costs.

Specialist Consultation
An initial consultation with an orthopaedic specialist typically ranges from $150 to $250.

X-Ray
This is the first-line imaging test and is very affordable, usually costing between $80 and $150.

MRI Scan
If the specialist needs to see the soft tissues in high detail, an MRI may be ordered. This is more expensive, often ranging from $1,000 to $2,000 per joint.

The final bill for knee ligament surgery is derived from several components. A combined MCL and PCL reconstruction, being more intricate than an isolated procedure, will naturally incur higher costs.

  • Facility Choice: Surgery at a private hospital generally involves higher daily ward and facility fees compared to subsidised rates at public institutions.

     

  • Surgical Complexity: An isolated MCL repair is less extensive than a full PCL reconstruction, especially if it’s part of a multi-ligament injury requiring advanced graft preparation and fixation devices.

     

  • Graft Type: The use of an allograft (donor tissue) versus an autograft (patient’s own tissue) can impact material and processing costs.

  • Rehabilitation: The mandatory, long-term physical therapy, often involving many sessions over 6-12 months, contributes a substantial part of the overall financial commitment.

Medisave

Medisave can be used to pay for hospitalisation and approved surgical procedures, up to specific withdrawal limits. For example, a complex knee replacement is claimable up to a certain amount from the Table of Surgical Procedures. 

MediShield Life

This is a basic health insurance plan that helps pay for large hospital bills and selected costly outpatient treatments.

Integrated Shield Plans (IPs)

If you have an IP from a private insurer, it works on top of MediShield Life. These plans are what cover the bulk of the cost if you choose to be treated in a private hospital or an A/B1 ward in a public hospital. It is essential to check your specific plan for coverage, deductibles, and any co-payment required.
