Understanding Meniscus Injury

The meniscus is a C-shaped pad of cartilage that cushions the knee joint. Tears can occur suddenly during sport or gradually through wear over time. A torn meniscus can cause pain, swelling and mechanical symptoms such as locking.

Common Symptoms

  • Pain along the joint line, especially when twisting
  • Swelling that may develop over 24 hours
  • Locking or catching of the knee
  • Reduced range of motion

Common Causes

  • Sudden twisting or pivoting during sport
  • Degenerative tears from wear over time
  • Deep squatting or heavy lifting
  • Age-related cartilage thinning

How Assessment Works

Assessment combines a history of the injury, physical examination tests for meniscus integrity, and imaging — typically MRI — to confirm the tear and its location and severity.

Treatment Options

  • Rest, activity modification and physiotherapy
  • Ultrasound-guided injections for symptom relief
  • PRP and regenerative therapies (where appropriate)
  • Knee arthroscopy for repair or trimming when indicated

When to Seek Specialist Care

Seek specialist care if you have persistent knee pain after an injury, locking, inability to fully straighten the knee, or symptoms that do not improve within a few days.

Frequently Asked Questions

Does every meniscus tear need surgery?

No. Many tears, especially degenerative ones, improve with non-surgical treatment. Surgery is considered for certain tears causing mechanical symptoms or not responding to conservative care.

How is a meniscus tear diagnosed?

A specialist assessment with physical examination and MRI imaging is typically used to confirm a meniscus tear and assess its severity.
