Knees keep giving way - 2 year old

(13 Posts)

My 2yr old son has been having problems with his knees giving way, which either results in him falling to the floor or dipping down as he's walking. His childminder had mentioned it a couple of times, saying that he appeared to have weak legs and he'd be walking alongside another child in a buggy & he'd be there one minute & on the floor the next. I had never seen it happen and just put it down to him being clumsy as he rushes a lot and doesnt always look where he's going.

Last week i was getting him ready to go out & he tried to stand up and his knees just gave way, as though someone had swipped his leg from behind & he'd just buckle to the floor. He doesnt appear to be in any pain & can jump, run, kneel etc. I took him to the doctor but by the time we had got there, he seemed to have made a miraculous recovery & was running about. She still checked him over, said she had no concerns & it could be related to growing & to keep an eye on him, look for any patterns (such as does it happen when he's tired, been sitting, kneeling etc).

It happened a lot over the next 2-3 days and now approx 1 week later, seems to be happening a couple of times a day. He also seems to get 'twisty' legs when he's standing sometimes, a bit like how he used to squirm when he was potting training & needed a wee. Again, he appears to be in no pain.

I would appreciate any help that you can offer. Have any of your children had this issue? Do you know of any kids that had/have this?

I look forward to hearing any suggestions or support.

I would go back to the GP and maybe ask for a referral to an orthopedic specialist...or at least a pediatrician. He couldn't make a miraculous recovery because it's an on off thing isn't it....the GP must not have seen any muscular problems....or injuries....but he's still doing it and you're going to worry every time you see it. It could just be that he's growing and there's a bit of a weakness there but you'll not rest tiil you know.

There can be a virus that temporarily does this. But to my knowledge it happens for about 24-48 hours then clears, but there could be something like that.

If it happens again, if you can get video evidence it will help, but I would push for referal.

video if you can and record in a notebook every instance.
ask childminder too to do this and note when it happens.

go back to gp and ask for a referral to a paediatrician for assessment and tests. you want to rule out any major muscle disorder.

is he very flexible? hypermobile joints can cause clumisness falling over - and that can impact to a degree but physio can help.

but you want to rule out muscle conditions.

gp or paed can run muscle function tests for example. eg blood test for creatinine kinase - if is is extremely high it is a sign of muscle disease and would need further testing

you need to look at things like
•The way your child stands.
•The way your child walks. Children with muscle disorders often have a typical style of walking, which is sometimes described as ‘waddling’. Later on, they may tend to stand and walk on the front part of their foot, with their heels off the ground.
•Whether your child has an exaggerated inward curve of their lower back. The medical term for this is lordosis. It is also sometimes called ‘sway back’.
•Whether your child has an outward or sideways curvature of their spine, known as scoliosis.
•Whether your child’s calves and other leg muscles look large compared with other muscles that may be poorly developed.

if you can see any of those then highlight them to gp

the other thing is to check if he loses consciousness at all when he drops. does he need to be roused? does he stop for a second or is alert and responsive ? let gp know which it is

also how does he get from sitting to standing? does he use his hands to assist? or just gets up like any other child?
Your child might also find it difficult to stand up from sitting on the floor. They may use what is known as the Gower's manoeuvre to do this. The Gower's manoeuvre is where a child stands up by:

•facing the floor
•placing their feet wide apart
•lifting their bottom first
•using their hands to ‘walk up’ their legs (placing their hands first on their knees, then on their thighs)

Just to reassure you my dd did this at around 28 months for several weeks. She's now 3.5 and hasn't done it since. I wonder if it was a virus that persisted for a while

Thank you all for your thoughts & comments. It hasn't been as bad for the past couple of days but there is definitely some sort of weakness there as even if he doesn't fall, his knees are still dipping randomly during the day.
He doesn't appear to get up unusually or using his hands & no curved back or unusual legs that I can see.
He's got another virus/temperature at the moment (he's had several recently) & I'm 1 week away from having another baby so I thin I'll monitor it for the moment, keeping track on how often it happens etc & then go back to for a referral in a couple of weeks.

Hi there Emma,
Just wondered what happened with your little boys legs after all?
My daughter has just turned 2 and everything you have written in your post applies to her too. I'm quite worried and not sure what to do! I hope you get to read this, please let me know.
Many thanks

Hi, my 16 months old having same issue for the past 3 days. How is your kid now?

Hi - did any of you get to the bottom of this? I spent last night in A&E with my 2yo son who suddenly couldn't bear weight on his legs without them giving way. They did lots of X-rays and couldn't see anything wrong and basically told me he's attention seeking - but I know he isn't. Firstly I don't think it would actually occur to him to make up something so elaborate - he's only two - but also, the shock and fear on his face when they buckle is definitely genuine. I'm not really sure what to do next?

Many thanks

Hey all just wondering has anyone gotten to the bottom of this? I have a 3 year old son who is going through the same thing and it has been on going for about a year. Finally got a gp referral so just waiting on appointment coming through now. I have a history of joint hypermobility which has caused my kneecap to dislocate quite a few times now and doctor seemed very concerned when I told him my history and how it may be linked to my son's weak knees. Also he has started to twist in bed at night for about an hour so i am also exploring the link between the clumsiness and restless leg syndrome??

Hello did anyone ever figure out the cause of this? My 15 month old nephew is now experiencing this. Please help.
