Torn Meniscus

A torn meniscus is an injury to one or two of the C shaped pieces of cartilage that curve around the inside and outside of the knee. The main function of the menisci is to stabilize and cushion the joint.

An injury to the meniscus most often occurs during a twisting or pivoting motion which causes a sheering force too strong for the menisci to cushion. In athletes, a torn meniscus is common to occur when a ligament of the knee is torn.

Symptoms:

  • "Popping" sensation
  • Swelling
  • Stiffness
  • Pain, especially while twisting or rotating at the knee
  • Pain while weight bearing
  • Limited range of motion or "locking" sensation at the knee

Common causes:

  • Aggressive or repetitive twisting or pivoting at the knee
  • Sudden stops and turns
  • Kneeling, deep squatting or heavy lifting
  • Degeneration due to age, weakness, or muscular imbalances result in excessive or uneven pressure on the meniscus

Risk Factor:

  • Sport including football, tennis, basketball, or volleyball
  • Jobs which involve deep knee bends or heavy lifting
