Meniscus Injury

When the knee's cushion is damaged — catching, locking, and pain

The meniscus is a C-shaped cartilage cushion between the thighbone and shinbone inside the knee.
Sudden twisting, direction changes in sports, or age-related wear can cause the meniscus to tear.
Because the meniscus has poor blood supply, it has limited ability to heal on its own.

1
Twisting force is applied to the knee

Sudden direction changes, jump landings, or squatting create twisting stress

2
The meniscus cracks or tears

The twisting force or age-related degeneration causes the meniscus to tear

3
Pain, catching, and swelling occur

The torn meniscus interferes with knee movement, causing pain and swelling

📅

Return to sports is achievable with proper rehabilitation

After partial meniscectomy, return to sport is possible in about 3 months. After meniscus repair, about 6 months. Individual timelines vary, but thorough rehabilitation focusing on range of motion and strength is essential. An MRI gives an accurate diagnosis; if one is needed we arrange it at a partner facility.

💡 Protecting Your Meniscus

  • Strengthening and stretching help protect the meniscus
  • Always warm up thoroughly before sports
  • Knee locking (sudden inability to straighten) is a sign to see a doctor
  • If catching or swelling persists, an MRI exam is recommended
