Meniscal injuries ?

Meiscal injuries are very common and associated with significant pain and rigidity.

More common in adults and less common in children .

Adults playing games like includes marathoners, sprinters, football ,rugby and so on.

There is a higher prevalence in males as compared to females.

Generally, the meniscus gets teared ,when we rotate in contact sports .

And not just this grinding and compression test, will do , but MRI is must to check out the grades of meniscus tear.

Meniscus anatomy?

Meniscus is a more like cresent shaped moon like structure.

2 types of menisci are present:-

  • Medial meniscus
  • Lateral Meniscus

Its blood supply is very low , and gets blood supply through diffusion .

The meniscus acts like a cushion or shock absorber for the knee joint .

Ask the patient to flex the knee at 90° angle.

First distract the knee joint .

Then passively, rotate the tibia laterally and medially both side .

If the patient complaints pain or painful movement , then it is said to be ligamentous injury.

If we compress the knee joint , and then rotate the tibia laterally and medially , then it is said to be meniscus injury.
