Patellar Tendon Rupture

[K.Haroon]

It is generally accepted that healthy, “normal” patellar tendons do not rupture. That is, there is an underlying degeneration in the tendon prior to complete rupture. The usual circumstance surrounding a patellar tendon rupture is when a person suddenly contracts the quadriceps muscle when the knee is in a flexed position. A common example is running up a flight of stairs or when a running back stops running quickly to change direction.

An athlete that has a patellar tendon rupture has immediate pain and swelling in the knee. He or she will often say they felt a “rip” or “tear” sensation and will be unable to ambulate because of weakness and pain.
