I’m a runner for over 20 years and after I ran the 2011 NYC Half Marathon, I started feeling some discomfort in my right knee, but I did not put too much attention.

Knee pain was a part of my life for over twenty years, but it became increasingly worse to the point where I had episodes of significant swelling every other week.

Overview

Damaged cartilage of the kneecap (patella) or groove (trochlea) is categorized differently than the cartilage damage from generalized arthritis. This type of cartilage damage is usually the result of a kneecap dislocation, direct knee trauma, or kneecap malalignment.

Why is knee cartilage important? 

Cartilage is the shiny, smooth coating at the end of bones.  It protects the bone and allows the bones to move smoothly and efficiently.  Damaged cartilage is known as arthritis.  When cartilage thins, or has a piece missing, it puts more stress on the bone and causes pain. 

Patellar cartilage surgery is most often performed on patients from age 12 to age 50. It's an ambulatory surgery, meaning you will be in and out of the hospital in the same day. The typical recovery time after surgery is between 4 and 9 months, and includes intense physical therapy to ensure an optimal recovery. 

Cartilage is: A resilient and smooth elastic tissue, rubber-like padding that serves to cover and protect the ends of long bones at the joints, and is a structural component of the rib cage, ear,  nose, bronchial tubes, intervertebral discs, and many other body parts. 

Symptoms of cartilage damage include:

  • Pain that may continue even when at rest, and worsen when you put weight on the knee
  • Swelling
  • Stiffness
  • A clicking or grinding sensation.
  • Joint instability, locking, catching, or buckling 

Common causes of cartilage damage include:

  • Kneecap dislocations,
  • Trauma (such as a direct fall on the knee)
  • Kneecap tracking incorrectly (often called malalignment)
