Unable to bend knee

by Katie Marshall

I have been unable to bend my knee for 3 months and i have a limp.

I have seen an orthapedic knee consultant who cannot find anything wroung and now i am seeing a neurologist.
I have had an mri and am due to have eeg nerve test soon.

My calf is swollen and so is my knee and it is a reddish colour.
I have tried bending it but i cannot move it.
The neurologist thinks it may be either rheumatoid arthritis or nerve entrapement.

Your opinion on this would be much appreciated.

knee pain

I would also lean toward rheumatoid arthritis or some type of nerve involvement. If the MRI didn't show anything, it could very well be a systemic type of problem.

good luck!

Unable to Bend Knee

Thanks for your comments Bart

I too think it is Rheaumatoid arthritis.

I also have been experiencing headaches,tingling in right hand and burning sensations.Could this all be related.

Is it safe to leave someone with suspected rheumatoid arthritis for such a long time?

I have very little knowledge about Rhuematoid arthritis other than recognizing the symptoms and knowing when to refer to a specialist. I wish I could give you a little more information.

I did limb lenghtening of 6.5 cm on my femurs, and knee stiffness is noraml. However, there is something like mold which grows around the knee joints. This makes it very hard for the joint to move and the range of motion becomes limited. Therapy, Stretching the knees back, then holding in the stretched position for 30 seconds and then releasing slowly is the best way. Also heat up your knees and quads so they can move better. Therapy is the best option to regain the motion. Also, if you have a fixator still in your leg, it is also uncomfortable and when it is removed therapy will get much easier.

MRI may not show everything
by: Anonymous

I had a similar issue, I could not straighen my knee and had to limp. The MRI did not show anything because of the position of the MRI. My cartilage had bent in half behind my knee cap making me not be able to straighten my leg. I went through arthroscopic knee surgery and it helped greatly. However years later my knee still hurts some as there is no cartilage remaining.

cant bend knee after knee replacement NEW
by: Anonymous

I was told that most knee replacement "hardware" limits full flexion. You will not be able to flex it fully. I would like to find yoga poses that take this limitation into consideration.

I had knee pain late last year. Thought its due to my past knee injuries. It was quickly cured and relieved using Origin Point discovered by a Taiwan doctor. Anyone can learn and apply it to friends and family. Specifically for knee pain, it's a massage at the buttocks area.
