The meniscus is a C-shaped piece of cartilage in the knee that acts as a shock absorber between the thigh bone (femur) and shin bone (tibia). Each knee has two menisci. One on the inner side and one on the outer side. They play a vital role in cushioning the joint, distributing weight evenly, and maintaining stability during movement.

A meniscus tear occurs when this cartilage is damaged, usually from twisting or sudden impact. Depending on the severity, the tear may cause pain, swelling, stiffness or even a sensation that the knee feels “loose.”

What are the types of Meniscus Tears?

Meniscus injuries are classified based on the pattern and location of the tear. This includes:

• Radial tear – extends from the inner edge of the cartilage outward, often caused by sudden twisting movements.
• Horizontal tear – splits the meniscus into top and bottom layers, sometimes producing a flap of loose tissue.
• Flap tear – creates an uneven fragment of cartilage that can get caught in the joint, leading to locking or catching.
• Complex tear – involves a combination of patterns, usually in older patients with degenerative changes.
• Bucket-handle tear – a large tear where part of the meniscus is displaced into the joint, often causing the knee to lock.

What causes a Meniscus Tear?

Meniscus injuries may affect both young athletes and older adults, although the underlying triggers are often different. While sports and trauma are common causes in the young, age-related wear and degeneration play a greater role in older individuals.

This can include:

• Age-related degeneration – as you age, the meniscus becomes thinner and less elastic, making it more prone to tearing even with minor movements.
• Trauma during activity – sudden twisting of the knee, rapid pivoting, squatting, or heavy lifting can tear the cartilage.
• Sports injuries – football, basketball, tennis, and other activities that involve sharp turns and quick stops put the meniscus under stress.
• Previous knee injury – having had ligament or joint problems increases the likelihood of developing a meniscus tear.

What are the symptoms of a Meniscus Tear?

The symptoms can vary depending on the size and location of the tear. Some patients may be able to walk, while others find their knees unstable or locked.

These include:

• A sensation of instability or “giving way”
• Catching or locking of the knee during movement
• Limited range of motion, making it difficult to fully bend or straighten the knee
• Pain along the knee joint, especially when twisting or squatting
• Swelling or stiffness that develops over several hours

Who has a higher risk of a Meniscus Tear?

A meniscus tear can happen to anyone, but certain groups of people are more vulnerable due to lifestyle, age, or previous injuries. Some of the groups that are more vulnerable to injury are:

• Athletes in high-impact sports – footballers, basketball players, and tennis enthusiasts often perform sudden pivots, turns, or tackles that increase the strain on the meniscus.
• Repetitive occupational strain – jobs that require frequent squatting, kneeling, or heavy lifting put continuous pressure on the knee joint.
• Older adults – with age, the cartilage becomes thinner and less resilient, making it more likely to tear even with minor movements.
• History of knee injuries – your risk of a meniscus tear increases if you have previously injured your ligaments or cartilage.
• Obesity – carrying excess body weight places additional stress on the knee, accelerating wear and increasing the risk of tears.
• Poor muscle strength or imbalance – weak thigh and hip muscles can reduce stability around the knee, leaving the meniscus more vulnerable to injury.

What are the complications associated with a Meniscus Tear?

An untreated meniscus tear carries complications and increases the risk of further joint damage. If the delay is prolonged, it may lead to:

• Early onset knee arthritis due to uneven load distribution in the joint
• Limited mobility
• Persistent pain and swelling
• Recurrent locking or instability

How is a Meniscus Tear diagnosed in Singapore?

Identifying a meniscus tear requires more than just a description of knee pain. Dr James Tan will carry out a detailed evaluation that combines discussion, examination, and imaging to confirm the diagnosis and rule out other conditions.

• Medical history – the consultation usually begins with questions about the onset of symptoms, recent activities, sporting habits, or past knee problems. This information provides essential context and helps Dr James to narrow down possible causes.

• Physical examination – the knee is then assessed for swelling, tenderness, and stability. Specific manoeuvres, such as the McMurray’s test, may be performed to reproduce the pain or detect clicking within the joint, both of which can point to a meniscus tear.

• Imaging studies – magnetic resonance imaging (MRI) scans remain the most reliable tool for visualising cartilage damage and determining the type and extent of the tear. X-rays may also be recommended, not to see the meniscus directly, but to exclude fractures or degenerative arthritis that could mimic similar symptoms.

Can a Meniscus Tear heal on its own?

A meniscus tear does not usually heal on its own because the meniscus has limited blood supply. The outer third, or “red zone”, has better blood flow, so small tears there may heal over time with some rest and activity modification. However, the tears in the inner two-thirds, or “white zone”, typically don’t heal by themselves.

Whether it heals largely depends on the following factors:

• Location of the tear
• Size and type of tear
• Age and activity level
• Symptoms 

This makes diagnosis important, because not all meniscus tears are the same. A proper examination with your doctor ensures you get the right care plan tailored to your specific condition, preventing further damage and supporting a safe return to normal activities. 

How is a Meniscus Tear treated in Singapore?

Managing a meniscus tear requires a thoughtful approach that considers the type of tear, its severity, and your lifestyle needs. In Singapore, treatment options range from simple measures that ease discomfort and swelling to modern surgical techniques designed to restore stability and protect the knee joint for the long term.

This may include:

Conservative Measures

• Rest and Activity Modification – patients are often advised to keep weight off the injured knee by using crutches or a cane, and to avoid activities that put strain on the joint. Applying the RICE protocol, which encompasses rest, ice, compression, and elevation, can further ease swelling and discomfort, giving the knee an opportunity to recover.

Non-Surgical Treatments

• Medication – non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen or naproxen can help reduce pain and inflammation. In cases of more severe discomfort, stronger prescription medicines may be considered, but always under medical guidance.

• Corticosteroid Injections – delivered directly into the knee, corticosteroid injections can provide relief from pain and inflammation, sometimes lasting weeks or months. While effective, they are used cautiously as repeated injections may affect cartilage and surrounding tissues.

• PRP Injections – platelet-rich plasma (PRP) and other biologic injections are obtained from the patient’s own blood, bone marrow, or fat cells. These injections may reduce inflammation and stimulate healing in the injured meniscus, offering a natural method of support.

• Assistive Devices – a knee brace or crutches may be recommended to stabilise the joint and offload pressure, allowing the meniscus to heal more effectively while reducing pain.

Rehabilitation

• Physical Therapy – once swelling has subsided, a structured physiotherapy programme becomes central to recovery. Tailored exercises help strengthen the thigh and leg muscles, restore flexibility, and improve the knee’s range of motion. The programme is adjusted gradually, moving from gentle movements to more dynamic activities, ensuring a safe return to daily life and sport.

A meniscus tear can do more than cause pain in the knee. It can limit mobility, disrupt everyday routines, and make simple tasks such as walking or climbing stairs increasingly difficult. If treatment is delayed, the injury may also raise the risk of long-term problems such as arthritis and persistent joint instability.

With the right treatment, however, many patients can return to their normal activities and protect the future health of their knees. If you have been experiencing ongoing knee discomfort or suspect that you may have sustained a meniscus tear, we encourage you to schedule a consultation with Dr James Tan. A thorough diagnosis and a carefully planned treatment strategy can help restore strength, flexibility, and lasting comfort.
