knee pain

[joshman]

Hi I am 15. I have had pain in both of my knees from excessive running. And I would like to know what it is that is wrong with my knees. I went to the doctor and he diagnosed me but I lost the paper. So I do not know what is called. The pain is under both sides of my knee cap. It occurs when I go down stairs; bend my knees to jump, and thrust forward on a bike. The doc said the tendons, or ligaments (I can't remember which) are too weak (due to the fact that my knee are still growing) to keep the knee cap from sliding over to far and causing inflammation and swelling in the knee.

So, it would be great if someone knows what is wrong and what it is called. Thanks.

Hi,
How are you feeling?
I think you might have ligament and quad weakness with impingement of nerve which is causing problem.
Have you got any imaging study done?
You should be asking for X-ray study and discuss those with an orthopaedician.
You can discuss with physiotherapist for optimum intervention with physical therapy.
Keep me posted.
Bye.

No, there is no grinding or anything like that. But when I move the knee cap and the leg is totally relaxed there is a vibration (I can’t think of the right word). It just feels like the knee is vibrating when I move the knee cap up and down.

It fine when I am sitting walking and doing basic movements. But when I jump and run in basketball, thrust forward on a bike, kneel, or do exercises such as squatting or lunges.

The pain is pretty bad. It is a sharp pain, in the upper and inner portion of the knee. I can take a little pain I practice Brazilian Jujitsu. But, this is so bad that I can't keep pedaling my bike. But, almost as soon as I start walking again the pain become almost unnoticeable.

Yes, I use knee braces. They allow me to play basketball and other sports. But, without them I might as well take up golf. lol

No surgery. No hip pain. No ankle pain due to this injury.

Thanks alot

Hi,
How are you feeling?
Your symptom of pain behind the knee cap suggests that your pain can be due to either a ligament weakness or meniscus issue.
When any patient complains of “knee pain,” the initial differential diagnosis in most of the cases includes: Osteoarthritis, Ligament damage, Meniscus damage or Patello-femoral disorder.
If you give little detail regarding your symptomatology it will helpful in discussing further.
When did your pain begin, what were you doing at the time, and what were the initial symptoms?
Do you experience any grinding, locking, catching, or giving way of the knee?
Are there any positions that make your knee more or less comfortable?
What is the quality of your pain (sharp, shooting, dull, etc.)?
Have you tried anything to help the pain and, if yes, has that been successful?
Have you ever had surgery on your knee? Do you have any hip or ankle pain?
Keep me informed.
Bye.
