Meniscus Tear MRI Scan: Detection, Diagnosis, & Procedure

What is an MRI scan for meniscus tears?

MRI scans for meniscus tears are non-invasive imaging tests used to detect damage or injury to the meniscus — the C-shaped knee cartilage that cushions and stabilises the joint. These scans help clinicians assess the type, location, severity of the tear, and guide appropriate treatment plans, whether conservative management or surgical intervention.

Unlike X-rays or CT scans, MRIs do not use ionising radiation, which makes them safer for repeated use. In Singapore, MRI scans for meniscus tears are performed at specialised orthopaedic clinics or in public or private hospitals equipped with MRI machines.

How MRI scans help diagnose meniscal tears

MRI scans are widely used to evaluate common knee injuries, particularly for detecting and assessing meniscal tears. They offer clear, high-resolution images of soft tissue structures, making them an essential diagnostic tool in evaluating sports injuries and general orthopaedics.

• Detecting the presence of a tear

  • MRI provides a detailed view of the meniscus, allowing clinicians to identify tears that may not be visible on a physical examination or X-ray. It is especially useful in identifying subtle or complex tear patterns

• Assessing the severity and type of tear

  • MRI helps determine whether the tear is horizontal, vertical, radial, bucket-handle, or complex.

  • It also evaluates the size and location of the tear, which influences treatment choices.

• Identifying associated injuries

  • MRI can detect other internal damage, such as ligament injuries (e.g. ACL injuries), cartilage defects, or bone bruises.

  • Identifying these related injuries is crucial for comprehensive treatment planning.

• Supporting treatment decisions

  • MRI findings help clinicians decide between conservative management (e.g., physiotherapy) or surgical intervention.

  • Tear characteristics such as poor blood supply or mechanical symptoms often lead to surgical recommendations.

• Pre-surgical planning:

  • For patients undergoing knee surgery, MRI provides a clear roadmap of the joint’s condition.

  • Surgeons use this information to plan the most effective approach for repair or removal of the torn meniscus.

When should you have a meniscus tear MRI scan?

An MRI scan is not always the first step following a suspected meniscus tear, but it becomes valuable in situations where accurate diagnosis is needed. Knowing when to get an MRI can help prevent further damage and guide appropriate treatment. 

• You experience persistent knee pain

  • Pain that doesn’t improve with the RICE method or physiotherapy may indicate a more profound issue, such as a tear that needs further investigation.

• You feel your knee locking, catching, or giving way

  • These mechanical symptoms are common with meniscal tears and often signal a need for imaging to confirm the diagnosis.

• There is significant swelling or stiffness

  • Swelling that recurs or does not resolve within a few days can suggest internal joint damage.

• You have limited knee movement or difficulty straightening your leg

  • A tear may be interfering with the knee’s normal function and range of motion.

• Initial treatments haven’t worked

  • If conservative approaches like rest, physiotherapy, or medication haven’t provided relief, an MRI can help reassess the cause of your symptoms.

• Your doctor suspects other associated injuries

  • MRI scans can also detect related injuries such as ACL tears or cartilage damage that may affect treatment planning.

• You are considering or preparing for surgery

  • MRI provides detailed images that help orthopaedic surgeons plan the most effective surgical approach if needed.

Whether it's a suspected meniscus tear, cartilage damage, or persistent knee joint discomfort, a detailed MRI scan can uncover the root cause and guide you towards effective treatment.

When would a doctor order an MRI scan for a meniscus tear?       

Doctors typically recommend an MRI for a meniscal assessment when symptoms persist or there is a need to visualise the injury in greater detail before deciding on a treatment plan. Therefore, a doctor may order a meniscus tear MRI scan if:

• Knee pain, swelling, or stiffness persists

• The knee locks, catches, or feels unstable

• X-rays don’t explain the symptoms

• Physical tests (e.g. McMurray’s, Apley’s) suggest the presence of a tear

• A complex or degenerative tear is suspected and may require surgery

What is the procedure for a meniscus tear MRI? 

A meniscus tear MRI is a safe, non-invasive scan used to capture detailed images of the knee's internal structures. Here’s what to expect:

Before the scan

• No special preparation is usually needed.

• Inform your doctor if you have any metal implants or pacemakers, or if you’re pregnant.

• Remove jewellery and metal objects before the scan.

During the scan

• You will lie on your back with your knee positioned inside the MRI machine.

• Your knee may be supported to keep it still during the scan.

• The procedure typically takes 20 to 45 minutes.

• The machine will make loud tapping noises—earplugs or headphones are provided.

• Staying still is important for capturing sharp, accurate images of the meniscus.

After the scan

• You can return to normal activities immediately.

• A radiologist will analyse the images to check for meniscal tears or other knee damage.

• Your doctor will then explain the results and discuss next steps, such as physiotherapy or surgery if needed.      

Price of an MRI scan for meniscus tear in Singapore

The cost of an MRI scan for a meniscus tear in Singapore is different depending on various factors, including the physician and whether the scan is conducted at a public or private facility.

At subsidised rates in public hospitals, an MRI scan ranges between SGD 300 and SGD 600. The price may be higher in some instances for non-subsidised patients or referrals from private clinics.

Private facilities or hospitals range from about SGD 700 upwards to more than SGD 1200, depending on the complexity of the scan as well as whether specialist consultation is included or not.

Some important factors that may affect the total cost include:

• The need for specialist interpretation or follow-up consultation

• Urgency of the scan

• Inclusion of pre- or post-scan services

Patients may use MediSave to offset part of the cost, especially if the scan is medically indicated. However, coverage amounts and eligibility vary, so it is advisable to check with your healthcare provider or the relevant institution beforehand.

What should I do if my MRI shows a meniscus tear?

If your MRI confirms a meniscus tear, the next steps will depend on the type, location, and severity of the tear, as well as your symptoms and activity level: 

• Consulting an orthopaedic specialist

  • They will review your MRI results and recommend the most suitable treatment plan.

• Conservative management

  • For small or stable tears, treatment may involve rest, physiotherapy, anti-inflammatory medication, and activity modification.

• Surgical options

  • If the tear is large, causing mechanical symptoms (like locking or instability), or not responding to non-surgical treatment, your doctor may recommend procedures such as meniscus repair or partial meniscectomy.

• Rehabilitation

  • Whether treated surgically or non-surgically, a structured rehab plan will help restore knee strength, flexibility, and function.

FAQ

Can a torn meniscus be seen on an MRI?

Yes, an MRI scan is highly effective at detecting meniscal tears. It can accurately identify the location, size, and type of the tear, making it a key tool in diagnosis and treatment planning.

Should I get an MRI for a meniscus tear?

You should consider an MRI for a suspected meniscus tear if you have ongoing knee pain, swelling, locking, or instability—especially if symptoms don’t improve with rest or physiotherapy. 

What are the MRI criteria for a meniscal tear?

Radiologists look for several key features on an MRI to diagnose a meniscal tear:

• Abnormal signal intensity extending to the surface of the meniscus, indicating a true tear

• Displaced meniscal fragments, such as in bucket-handle tears

• Altered meniscal morphology, including changes in shape, size, or contour

• Associated findings, such as joint effusion (fluid buildup) or bone bruising, which may support the diagnosis

These criteria help confirm the presence and severity of a meniscal tear and guide the appropriate course of treatment.

What are three signs of a meniscus tear in the knee?

A meniscus tear often presents with the following symptoms:

• Pain localised to the knee joints:

  • Especially along the joint line, which may worsen during twisting or squatting movements.

• Swelling and stiffness:

  • These symptoms may develop within hours of injury or gradually over a few days.

• Locking, catching, or instability: 

  • You may feel as though your knee is stuck, giving way, or unable to move smoothly through its full range of motion.

If you experience these listed symptoms, it’s important to seek medical advice for proper evaluation and timely treatment.

How accurate is MRI for detecting a meniscus tear?

MRI is highly accurate for detecting meniscus tears, with diagnostic accuracy typically ranging from 85% to 95%. The precision of the scan depends on factors such as the quality of the MRI machine, the skill of the radiologist interpreting the images, and patient-related factors like movement during the scan. 

When performed under optimal conditions, MRI provides a reliable and detailed assessment of the meniscus, making it one of the most effective tools for confirming meniscal injuries.

Can you tell if a meniscus is torn without an MRI?

Yes, a doctor can suspect a meniscus tear based on your symptoms, medical history, and physical examination tests like McMurray’s or Apley’s test. However, while these can indicate the likelihood of a tear, an MRI is needed to confirm the diagnosis and assess the severity, exact location, and any associated injuries.

Are there any risks associated with a meniscus tear MRI?

MRI scans are generally very safe, but there are a few considerations to be aware of, such as the presence of metal implants, rare allergic reactions to contrast dye, or discomfort for those with claustrophobia.

What is the difference between a normal meniscus and a meniscus tear on MRI?

On an MRI, a normal knee looks smooth, dark, and wedge-shaped with no breaks. A meniscus tear shows up as a bright line or spot that reaches the edge of the meniscus, indicating a tear. The scan may also show swelling, changes in shape, or loose fragments if the tear is severe.

Radial tears are a common type and typically appear as bright lines extending from the inner edge of the meniscus toward the outer rim. In more severe cases, the scan may also show displaced fragments, swelling, or joint effusion.
