Meniscus Tears
A common knee injury causing pain, locking, or catching during movement
Meniscus tears and injuries are common knee issues that can cause pain, swelling, and restricted mobility. Dr Ben McGrath, an orthopaedic specialist, offers expert assessment and personalised treatment plans to help patients manage symptoms, promote healing, and improve knee function.

What are Meniscus Tears and Injuries?
The meniscus is a C-shaped piece of cartilage in the knee that cushions and stabilises the joint. Each knee has two menisci—medial (inner) and lateral (outer). A meniscus tear can occur from sudden twisting or heavy impact, leading to pain and restricted movement. Meniscus injuries can range from minor tears to more severe damage that may require medical intervention.
Common Symptoms of Meniscus Tears
Patients with meniscus injuries typically experience the following symptoms:
- Knee Pain: Pain may be localised along the inner or outer side of the knee, often worsening with movement.
- Swelling: Inflammation may occur around the knee joint, particularly within the first 24 hours after injury.
- Locking or Catching Sensations: A torn meniscus can cause the knee to lock or catch during movement, making it difficult to fully straighten the leg.
- Reduced Range of Motion: Difficulty bending or straightening the knee due to pain and swelling.
- Instability: Feeling as though the knee is giving way or unable to support weight, especially during walking or climbing stairs.
If these symptoms persist, consulting Dr McGrath can help determine the severity of the injury and the best course of treatment.
Causes and Risk Factors for Meniscus Tears
Meniscus tears can result from a variety of factors, including:
- Sudden Twisting or Pivoting Movements: Movements that involve rapid direction changes, such as in sports, can lead to meniscus tears.
- Age-Related Degeneration: The meniscus becomes more prone to tearing as we age, even during routine activities.
- High-Impact Sports or Activities: Sports like football, basketball, and skiing, which place high stress on the knees, increase the risk of meniscal injuries.
- Previous Knee Injuries: A history of knee injuries, including ligament damage, can make the meniscus more susceptible to tears.
- Obesity: Carrying extra weight places added stress on the knee joint, contributing to meniscal degeneration and increased injury risk.
Dr McGrath takes these factors into account when assessing each patient’s risk profile and advising on preventive measures.
Diagnosis of Meniscus Tears and Injuries
Dr Ben McGrath conducts a thorough examination to confirm meniscus injuries and assess their severity:
- Physical Examination: Dr McGrath evaluates knee stability, tenderness, and range of motion, often using specific tests (e.g., McMurray test) to detect meniscus damage.
- Imaging Tests: MRI scans are commonly used to provide a clear view of the meniscus, helping confirm the extent of the injury. X-rays may also be used to rule out other conditions, though they do not show soft tissue damage.
An accurate diagnosis is essential for determining the most appropriate treatment, whether non-surgical or surgical.
Non-Surgical Treatments for Meniscus Tears
Non-surgical management may be effective for minor or stable meniscus injuries and can include:
- Rest and Activity Modification: Avoiding activities that stress the knee joint can help reduce pain and facilitate healing.
- Physiotherapy: A physiotherapist can guide patients through exercises that strengthen the surrounding muscles, improve flexibility, and support knee stability.
- Medication: Nonsteroidal anti-inflammatory drugs (NSAIDs) may be recommended to manage pain and reduce inflammation. Always consult a medical professional before starting any medication.
- Ice Therapy: Applying ice to the knee in the first few days following an injury can help reduce swelling and alleviate pain.
Non-surgical options aim to reduce symptoms and improve function, with tailored plans developed for each patient’s condition.
Surgical Treatments for Meniscus Tears
Surgery may be considered for more severe meniscus tears, particularly if symptoms persist despite non-surgical treatment. Surgical options include:
- Arthroscopic Meniscus Repair: Using minimally invasive techniques, Dr McGrath can repair the torn meniscus by stitching it back together. This approach aims to preserve as much of the meniscus as possible.
- Partial Meniscectomy: In cases where repair is not feasible, a portion of the damaged meniscus may be removed to relieve symptoms and improve joint function.
- Total Meniscectomy: Rarely performed, this involves removing the entire meniscus. While effective for symptom relief, removing the meniscus increases the risk of future joint issues and is typically avoided unless absolutely necessary.
Dr McGrath carefully considers the type and location of the tear, as well as the patient’s age and activity level, before recommending surgery.
When to See Dr Ben McGrath for Knee Pain
If knee pain persists or interferes with daily activities, especially if accompanied by locking, swelling, or instability, a consultation with Dr McGrath can provide an accurate diagnosis and explore effective treatment options.
FAQs About Meniscus Tears
Small tears on the outer edge of the meniscus (the red zone) may heal on their own with rest and physiotherapy. However, tears in areas with limited blood flow often require surgical intervention.
Recovery times vary, with meniscus repair generally requiring longer recovery (3-6 months) than a partial meniscectomy (4-6 weeks). Physiotherapy plays a vital role in the rehabilitation process.
Strengthening the knee and leg muscles, practising balance exercises, and maintaining flexibility can help reduce the risk of meniscus injuries. A physiotherapist can provide a tailored program for knee health.
