My knee collapses when running, with no apparent cause

This answer was rated:

My knee collapses when running, with no apparent cause though it happens consistently when I try to run downhill. I've also noticed that the same knee does not have the same range of motion- it locks up while still slightly bent, and the kneecap "pops" into place when fully straightened. It has been like this as long as I can remember, and the knee buckling has been happening since childhood. It's painful, and leaves me limping for 20-45 minutes after. What is wrong? How can I strengthen my knee/ keep this from happening? Unfortunately, surgery is not an option.
Dr. Nomi :

Hi,

Dr. Nomi :

Is there also pain at the side of knee.

Dr. Nomi :

Are you there?

Customer:

No, not at the side. Its more centralized. Like a dull ache

Dr. Nomi :

Any soreness in hip ?

Customer:

None.

Dr. Nomi :

Do you wear especial shoes for over pronation etc.?

Customer:

No, normal shoes. I have a pair of generic running shoes that I use.

Customer:

Walking is not a problem, except going down hill. Then I need to be careful. But walking/ everyday activity isn't an issue.

Dr. Nomi :

Do you used to play football in your teens?

Customer:

No, I was very inactive. I have no sports injuries. In fact, I've always avoided running/ physical activity because of this 'buckling knee' issue. I have a feeling its something I was born with? Is that a possibility?

Dr. Nomi :

Okay .Is anyone else in family has knee problem like yours ?

Customer:

My mom has always claimed to have weak knees. Not as bad as mine- hers don't buckle- but she also avoids running.

Dr. Nomi :

Okay.Last question?Do you have knocked knees?

Customer:

No, I don't.

Dr. Nomi :

Thanks for your input.There is possibility that there is some congenital problem of patella like small patella or weak patella that has lead you to have condition like patellofemoral syndrome.

Dr. Nomi :

However,nothing to worry about some exercises can help in this condition.

Dr. Nomi :

First of all,use a knee support or heat retainer (a patella stabilising support to control excess movement is best).

Customer:

That's great- can you suggest some?

Dr. Nomi :

Apply RICE (Rest, ice compression and elevation) after activity. This will help reduce pain.

Dr. Nomi :

Hamstring strenghtening exercises can also help in controlling patella.Like sit ups etc.

Dr. Nomi :

You will need to keep your weight under control through out your life.

Dr. Nomi :

Because more weight will cause more problems.

Dr. Nomi :

You can get your gait analysis to check if you are not over pronated.

Dr. Nomi :

Hope it helped.

Customer:

It did. One last question- where can I have my gait analyzed?

Dr. Nomi :

It is commonly available everywhere .Some times sports shops has machines .If you check in your area.

Dr. Nomi :

Google it :)

Customer:

Great. Thank you for your help!

Dr. Nomi :

I wish you all the best.:)

Customer:

bye
