Walking Disability

[Hossein_Karami]

My 2 year old son suddenly stopped walking. He was walking normally in the morning and had his breakfast then we he tried to stand up and walk he felt pain in his knee and below and had to crawl.
He has no fever and there is no swelling or bruise on his leg. he can bend his knee normally.
We are very worried. please tell us what to do.

Hi,
I think there could have been muscle pull or abnormal movement causing sudden jerk and then ligament weakness causing your son not to move.
Oral analgesics and analgesics rub should help him.
You should be doing imaging study of his knee to know the probable diagnosis. His imaging should include MR study to know about soft tissue structures around the knee joint.
You said your child is fine now, so what seems to be the problem.
Keep me posted if you have any queries.
Bye.

Hi,

My son started walking normally again while we were in touch with his doctor on phone until yesterday when we had my son examined by a pediatric.
The doctor watched my son walking and he did some other physical examinations on his both legs. There was no evidence of any patellar dislocation or any other simillar issues or unsual things , so he suggested that the pain could have been due to some normal physical activities. When I asked for further investigation such as sonar he said no need.
Since then, my son is walking, running and playing normally.
I would like to know your oppinon with a great appreciation.

Hi Hossien,
His symptom of sudden pain and fall suggests that either he might have ligament weakness or menisci problem.
Did he have deformity of knee joint when he had fallen?
I wanted to check whether he had patellar dislocation or sub-luxation.
Viral illness or any infection would have caused ascending type of paralysis; involvement of joint would not have been there.
Have you seen any pediatric orthopaedician? If yes, what did he say?
Have you got any imaging study done for your child? If yes, what is the report?
What medications is he on?

Hi, Thanks for your feedback.
After he finished his breakfast as usual started walking to his room playing with his toys, but suddendly sat down and pointed in his knee area, he again tried to stand up but failed with a lot of pain so that he had to crawl. He had no fever or no lump or any unusual thing on his knee and when I called his doctor he asked me to give him Brufen to ease the pain. the medicine was effective and in the evening he was again able to walk but not as usual. He had no surgery or any deseases related to his bones but last month he caught cold with running nose and it took him almost three weeks to get better. Could this be the reason? Any viral infection which could cause problem on his ligement?- just guseeing...

Hi,
How is your son feeling?
I think either he has patellar sub-luxation or patellar dislocation.
If you give little detail regarding your symptomatology it will helpful in discussing further.
I would like to know where the pain is exactly if you have to point out with your index finger.
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 posted.
Bye.
