New York Knicks, Jeremy Lin, to Undergo Knee Surgery

Linsanity will be pausing briefly.  Jeremy Lin, point guard for the New York Knicks, was diagnosed with a meniscal tear in his left knee.  He will undergo surgery later this week.  What is being done?

ANATOMY

The knee consists of 3 bones: the knee cap (patella), the thigh bone (femur), and the leg bone (tibia).  These three bones interact to give range of motion to the knee.  Inside the knee joint, the bones are covered with a substance known as cartilage.  The cartilage allows the bones to glide together, painlessly.  This substance is critical to the function of any joint in the human body.  Between the bones are cartilage discs, known as menisci.  These discs cushion the knee.

The meniscus can tear anywhere along its course.  These tears come in a variety of forms and can lead to pain, catching, popping, or clicking of the knee.

CAUSES

Meniscal tears can occur with trauma, twisting injuries, and arthritis.  Tears that are towards the central portion of the knee can be cleaned up, whereas those that are towards the periphery may be repaired.

SYMPTOMS

Not all meniscal tears cause symptoms.  However, symptoms can include pain, swelling, clicking, popping, or even catching.

TREATMENTS

Meniscal tears are treated with shaving procedure to “clean-up” the tear.

Occasionally, if the tear is located towards the periphery of the meniscus, a repair can be attempted.

WHEN TO SEEK MEDICAL CARE

If you suspect that you have symptoms concerning for a cartilage injury of the meniscus, you should seek medical attention.  A good physical exam, x-rays, and an MRI may be needed to evaluate the injury.

RETURN TO ACTIVITIES/OUTCOMES

Most athletes with meniscal tears that are treated with a shaving procedure are out of competitive play for 3-4 weeks. Those with meniscal tears that need to be repaired are out from competitive plays for at least 3 to 4 months. Extensive rehabilitation is needed to optimize the range of motion and strength of the knee.
