What happens when an athlete "blows out" their knee?

By October 31, 2005

Follow me on:

It was reported today that professional football player Daunte Culpepper sustained a severe injury to his knee in Sunday's football game. The injury was initially described as a "blown out" knee.

Using the diagnosis "blown out" knee is not terribly helpful in understanding exactly what structures were damaged nor what the injury prognosis will be. Saying a patient "blows out" their knee is much like saying the patient sustained a "knee sprain". Neither of these terms is a medical diagnosis.

The proper way to describe this condition is by stating which knee ligaments were damaged at the time of the injury. In the case of Daunte Culpepper's injury, he sustained damage to three of the four major ligaments in the knee; the anterior cruciate ligament, the posterior cruciate ligament, and the medial collateral ligament. This extent of damage to the knee and the treatment that will be required will certainly end the football season of this athlete.

how soon after an acute acl/pcl/mcl injury do athletes get their mri studies done?

It depends. An MRI can be performed at any time. Some physicians may recommend waiting for the swelling to subside after the injury to determine if the MRI is necessary. If you have an injury, ask your doctor when the right time to have an MRI would be. You may also find this helpful: Do I need a MRI?

Im only 17 and my knee’s pop every time I even take a step doctors say that my ligaments are not fully grown but I play sports. My question is should I get knee braces?

A lot of injuries can be treated with physiotherapy. I had to have physiotherapy in Milton Keynes after I hurt my knee from a dancing accident. It takes a while to fully heal but personally, I’d give it a go before opting for surgery!
