Meniscus Tear: Symptoms, Diagnosis and Treatment Options

Knee pain does not always come from bones or ligaments. Sometimes, the problem involves the cartilage structures that cushion the knee joint. A meniscus tear is one such injury and can affect people of different ages, including athletes, physically active individuals and older adults.

Some meniscus injuries happen suddenly when a person twists the knee while playing a sport or changing direction. Others develop gradually as the tissue becomes weaker with age. The symptoms can range from mild discomfort to significant pain, swelling and difficulty moving the knee.

Understanding Meniscus Tear Symptoms, Meniscus Tear Diagnosis and Meniscus Tear Treatment can help you recognise the problem and understand when medical assessment may be needed. The right treatment depends on the type and location of the tear, the condition of the knee and the person's daily activities.

What Is a Meniscus?

The meniscus is a crescent-shaped, wedge-like structure made of tough fibrocartilage inside the knee joint. Each knee has two menisci positioned between the thighbone, called the femur, and the shinbone, called the tibia.

These structures act as cushions between the bones. They help distribute body weight, absorb impact and improve the way the surfaces of the knee joint fit together.

The two menisci are:

• Medial meniscus: Located on the inner side of the knee. It is relatively less mobile and is commonly involved in knee injuries.
• Lateral meniscus: Located on the outer side of the knee. It helps distribute pressure across the outer part of the joint.

The meniscus plays an important role in maintaining knee function. It helps the joint manage everyday activities such as walking, climbing stairs, squatting and running.

What Is a Meniscus Tear?

A meniscus tear occurs when the fibrocartilage is damaged or split. The injury may involve a small section of the meniscus or a larger area that affects how the knee moves and bears weight.

Meniscus tears are broadly divided into two categories:

1. Acute meniscus tear

An acute tear occurs suddenly, often during physical activity or an accident. It may happen when the foot remains planted on the ground while the knee twists or rotates. A direct impact or deep squatting movement combined with rotation can also contribute to the injury.

2. Degenerative meniscus tear

A degenerative tear develops gradually as the meniscus becomes weaker with age and repeated stress. In some cases, a relatively minor movement, such as getting up from a low chair or stepping on an uneven surface, may trigger symptoms.

Degenerative meniscus tears are more common in middle-aged and older adults. They may also occur alongside knee osteoarthritis, which can influence the treatment approach.

Meniscus Tear Symptoms

Meniscus Tear Symptoms vary according to the size, location and pattern of the injury. Some people notice pain immediately after a twisting movement, while others develop discomfort gradually.

Common symptoms include:

• Knee pain: Pain may occur along the inner or outer joint line, depending on which meniscus is affected. It may become more noticeable while twisting, squatting or climbing stairs.
• Swelling: The knee may become swollen after the injury. Swelling can develop gradually over several hours or days.
• Stiffness: The knee may feel tight or difficult to move, particularly after sitting for a long time.
• Difficulty bending or straightening: Pain, swelling or a displaced piece of meniscus tissue may restrict normal knee movement.
• Catching or locking: Some people feel that something is catching inside the knee. A displaced tear can sometimes physically block movement.
• Clicking or popping: Clicking may occur during knee movement. However, clicking alone does not confirm a meniscus tear.
• Feeling of instability: The knee may feel unreliable or as if it could give way during certain movements.

Can you walk with a torn meniscus?

Yes, some people can walk with a torn meniscus. The ability to bear weight depends on the severity and location of the injury, the amount of swelling and whether the knee is mechanically blocked.

A person may initially be able to walk after an injury but notice increasing pain and swelling over the next few days. Others may experience difficulty walking from the beginning.

Being able to walk does not mean the meniscus is healthy. Persistent pain, swelling, catching or restricted movement should be assessed by a healthcare professional.

What Causes a Meniscus Tear?

The meniscus can tear when excessive force is placed on the knee or when the tissue becomes weaker over time. The causes are different for acute and degenerative injuries.

Common causes of acute tears

• Sudden twisting: Rotating the knee while the foot remains planted can place stress on the meniscus.
• Sports injuries: Football, basketball, tennis and other activities involving rapid direction changes can increase the risk.
• Deep squatting: A forceful or poorly controlled deep squat, particularly with rotation, may injure the meniscus.
• Direct impact: A collision or blow to the knee can damage the meniscus, sometimes along with other structures.
• Combined ligament injuries: Meniscus tears can occur alongside injuries such as an ACL tear.

Common causes of degenerative tears

• Age-related changes that reduce the strength and resilience of meniscus tissue.
• Repeated stress on the knee over time.
• Existing knee osteoarthritis and changes within the joint.
• Minor twisting or bending movements affecting already weakened tissue.

Types of Meniscus Tears

Meniscus tears can have different shapes and patterns. Identifying the tear pattern helps the orthopaedic specialist understand the injury and consider suitable treatment options.

The tear pattern alone does not determine whether surgery is needed. The specialist also considers symptoms, knee function, tissue quality and the location of the injury.

Meniscus Tear Diagnosis

Meniscus Tear Diagnosis involves understanding how the injury occurred, evaluating knee movement and checking for signs of damage inside the joint. A physical examination and imaging tests may be used together to assess the condition.

1. Medical history and physical examination

The orthopaedic specialist may ask when the pain started, whether there was a twisting injury, how the swelling developed and which movements make the symptoms worse.

The examination may include checking:

• Swelling and tenderness around the knee joint.
• Pain along the inner or outer joint line.
• Ability to bend and fully straighten the knee.
• Knee movement and stability.
• Pain or clicking during specific examination movements.

2. Meniscus examination tests

Some physical tests can help identify a possible meniscus injury. They are interpreted alongside the medical history and other examination findings.

• McMurray test: The clinician moves the knee through a controlled range while rotating the lower leg to check for pain or a clicking sensation that may suggest meniscal damage.
• Thessaly test: The patient stands and gently rotates the body with the knee slightly bent. Pain or other symptoms may indicate a possible meniscus injury. This test may not be suitable when the knee is very painful or unstable.
• Joint line tenderness: The clinician checks for tenderness along the inner or outer joint line where the meniscus is located.

No single physical test can confirm every meniscus tear. The findings need to be considered together with the patient's symptoms and, when appropriate, imaging results.

3. Imaging tests

MRI is an important investigation for evaluating meniscus injuries because it can show the location and pattern of a tear and help identify associated damage. However, imaging findings should be interpreted in the context of symptoms and examination results. Not every tear seen on an MRI requires surgery.

4. Knee arthroscopy

Knee arthroscopy is a minimally invasive surgical procedure in which a small camera is inserted into the knee through a small incision. It allows the surgeon to view the structures inside the joint directly.

Arthroscopy may be used when surgery is indicated to assess and treat the meniscus. It is not generally performed only to confirm a diagnosis when appropriate clinical assessment and imaging can provide the required information.

Meniscus Tear Treatment Options

Meniscus Tear Treatment depends on several factors, including the location and pattern of the tear, symptoms, age, activity level, tissue quality and the presence of other knee conditions.

Many patients do not need immediate surgery. Treatment may begin with activity modification and physiotherapy. Surgery may be considered when symptoms persist, the knee remains mechanically blocked or the tear has features that may benefit from repair.

1. Initial care and activity modification

After a suspected meniscus injury, the first step is to avoid movements that increase pain or place additional stress on the knee.

Initial care may include:

• Rest from aggravating activities: Temporarily avoid running, jumping, deep squatting and twisting movements that worsen symptoms.
• Cold therapy: Apply a cold pack wrapped in a towel for around 15 to 20 minutes at a time to help manage pain and swelling. Do not apply ice directly to the skin.
• Compression: A suitable compression bandage may help control swelling if it does not cause numbness, increased pain or changes in foot colour.
• Elevation: Raise the affected leg when resting, if comfortable, to help manage swelling.
• Support when walking: Crutches or other support may be recommended if walking is painful or unsafe.

These measures can help manage symptoms, but they do not replace a proper examination. Do not try to force a locked knee to straighten or return to sports while symptoms remain.

2. Medication for pain and swelling

A healthcare professional may recommend suitable pain-relief or anti-inflammatory medication depending on the patient's symptoms and medical history.

Not all medicines are appropriate for everyone. Existing medical conditions, allergies, other medications and possible side effects should be considered before taking painkillers or anti-inflammatory medicines.

3. Physiotherapy and rehabilitation

Physiotherapy is an important part of treatment for many meniscus injuries. A structured programme can help improve knee movement, strengthen the surrounding muscles and support better joint function.

Depending on the condition, rehabilitation may include:

• Range-of-motion exercises: Help improve comfortable bending and straightening of the knee.
• Quadriceps strengthening: Strengthens the muscles at the front of the thigh that support knee movement.
• Hamstring strengthening: Helps improve support and control around the knee.
• Hip and lower-limb strengthening: Supports better alignment and control during walking and other activities.
• Balance exercises: Help improve coordination and control of the affected leg.
• Functional training: Gradually prepares the patient for everyday movements and, where appropriate, sports-related activities.

Exercises should be selected and progressed according to the injury and the patient's tolerance. Avoid copying strenuous exercises from online videos without professional guidance, especially when the knee is swollen or painful.

4. Meniscus repair surgery

Meniscus repair is a surgical procedure in which the torn tissue is stitched together to support healing. The aim is to preserve the meniscus and maintain its role in cushioning and distributing forces across the knee.

Repair may be considered when the tear has a suitable pattern and location, the tissue is of adequate quality and the patient is likely to benefit from preservation.

The outer region of the meniscus has a better blood supply than the inner region. Tears in this area generally have greater healing potential. Some tears in the middle region may also be considered for repair depending on their characteristics.

Not every tear can be repaired. The final decision depends on the tear pattern, vascularity, tissue quality, associated injuries and the surgeon's assessment.

5. Partial meniscectomy

When a torn portion cannot be repaired and continues to cause symptoms, the surgeon may recommend a partial meniscectomy. During this procedure, the damaged portion of the meniscus is trimmed while as much healthy tissue as possible is preserved.

Partial meniscectomy may be considered for selected unstable or displaced tears that are not suitable for repair. It is different from removing the entire meniscus.

Preserving functional meniscus tissue is important because removing too much tissue can reduce the knee's ability to distribute load and absorb impact. Loss of meniscus tissue may increase the risk of degenerative changes over time.

6. Meniscus transplant

Meniscus transplantation may be considered in selected patients who have lost a substantial amount of meniscus tissue and continue to experience symptoms. The procedure involves placing donor meniscus tissue into the knee.

It is not a routine treatment for every meniscus tear. Suitability depends on factors such as age, knee alignment, cartilage condition, activity needs and the overall health of the joint.

How Does the Location of a Tear Affect Healing?

The meniscus does not have an equal blood supply throughout its structure. This is important because blood flow supports the healing process.

This classification is a general guide. It does not mean that every tear in the outer region will heal or that every tear in the inner region requires surgery. The complete clinical picture determines the treatment plan.

Recovery After Meniscus Tear Treatment

Recovery depends on the type of tear, treatment method, associated injuries and the patient's general health. A person receiving physiotherapy without surgery may follow a different recovery plan from someone who undergoes meniscus repair.

Recovery after non-surgical treatment

Patients managed without surgery may gradually improve as pain and swelling settle and knee strength returns. The duration varies according to the injury and the response to rehabilitation.

Progress is generally assessed by looking at:

• Reduction in pain and swelling.
• Improved ability to bend and straighten the knee.
• Better strength in the surrounding muscles.
• Comfortable walking and stair climbing.
• Ability to perform daily activities without significant symptoms.

Recovery after partial meniscectomy

Recovery after partial meniscectomy is generally faster than recovery after meniscus repair because the damaged tissue is trimmed rather than stitched for healing. Many patients can resume routine activities within a few weeks. General rehabilitation guidance suggests approximately three to six weeks for recovery, although timing varies with the amount of tissue removed, symptoms and activity demands.

Patients may begin walking and rehabilitation relatively early, depending on the surgeon's instructions and the condition of the knee. Returning to sports may take longer and should depend on functional recovery and clinical clearance.

Recovery after meniscus repair

Meniscus repair usually requires a longer recovery period because the repaired tissue needs time to heal. Rehabilitation commonly takes around three to six months, although some patients may need longer depending on the tear pattern, surgical technique and associated injuries.

Some patients may need temporary restrictions on weight-bearing or knee bending, depending on the tear pattern and surgical technique. Rehabilitation generally progresses through controlled movement, muscle strengthening, balance training and gradual functional activities.

Returning to demanding sports requires clearance from the treating team. Do not compare your recovery directly with another patient. The location and type of tear, the procedure performed and the presence of other injuries can all change the rehabilitation plan.

Can a Meniscus Tear Lead to Knee Osteoarthritis?

The meniscus helps distribute pressure across the knee joint and reduces concentrated stress on the joint surfaces. When it is damaged or a substantial amount of tissue is removed, the way forces pass through the knee can change.

Meniscus injuries may be associated with an increased risk of knee osteoarthritis, particularly when there is additional cartilage damage or significant loss of meniscus tissue.

This does not mean every person with a meniscus tear will develop arthritis. Appropriate assessment, treatment and rehabilitation can help manage symptoms and support knee function.

How Can You Reduce the Risk of a Meniscus Tear?

Not every meniscus injury can be prevented, particularly when it is related to age-related tissue changes or an accident. However, certain habits can help support knee strength and movement control.

• Strengthen the leg muscles: Regular exercises for the quadriceps, hamstrings and hip muscles can improve support around the knee.
• Warm up before exercise: Prepare the muscles and joints before sports or demanding physical activity.
• Use proper movement techniques: Learn controlled landing, squatting and direction-changing techniques.
• Increase activity gradually: Avoid sudden increases in exercise intensity or training volume.
• Wear suitable footwear: Choose footwear appropriate for the activity and playing surface.
• Respond to knee pain: Do not ignore persistent swelling, pain or restricted movement after exercise.

When Should You Consult an Orthopaedic Specialist?

Knee pain can have several causes, including meniscus injuries, ligament damage, cartilage problems and osteoarthritis. A proper assessment helps identify the likely cause and determine whether further investigations are needed.

Consider consulting an orthopaedic specialist if you experience:

• Persistent pain along the inner or outer side of the knee.
• Swelling that does not settle.
• Difficulty fully bending or straightening the knee.
• Repeated catching or locking sensations.
• Pain while walking, climbing stairs or squatting.
• A feeling that the knee may give way.

Conclusion

A meniscus tear is a common knee cartilage injury that can affect people of different ages and activity levels. It may occur after a sudden twisting movement or develop gradually due to age-related changes in the tissue.

Common symptoms include knee pain, swelling, stiffness, catching and difficulty bending or straightening the leg. Diagnosis generally involves a medical history, physical examination and imaging when required.

Meniscus Tear Treatment may include activity modification, physiotherapy and, in selected cases, arthroscopic surgery. Meniscus repair aims to preserve the damaged tissue, while partial meniscectomy removes only the portion that cannot be repaired. The appropriate approach depends on the individual injury and clinical findings.

Persistent knee symptoms should not be ignored. An orthopaedic assessment can help determine the cause of discomfort and guide treatment that supports knee function and long-term joint health.
