Mechanical instability caused by miserable malalignment?
« on: March 04, 2012, 10:40:44 PM »
I don't know exactly how to describe this or if I even used the correct term, but I hope someone can explain this to me. I have been diagnosed with miserable malalignment by my OS hip specialist and have an appt to see Dr. Teitge on April 10. My left is more pronounced and symptomatic than my right side and aside from both knees hurting, my left feels unstable. This is where I'm a little confused. My right knee does not feel unstable, but I've had episodes where I've gone to stand up and there is so much pain in my knee that I can't put weight down on it right away but after a few minutes it's ok. It never clicks or "gives way". My left knee however, often feels like it needs to be popped, or like I need to click it back in place and when it does click, it "gives out" but there's no sharp pain, just a dull ache and then a feeling of relief of pressure, if that makes sense. Once in awhile the left knee will get a knifing sensation medially.
So does miserable malalignment cause mechanical instability or do I not even have the correct term here? Is this a normal finding in miserable malalignment?

Well, it may or may not cause instability. You can have the same malalignment on both legs and one could be fine and the other not. There could also be problems with the knee itself (loose ligaments) that would cause instability. Dr. T is amazing and I'm sure you'll get all your questions answered.

I am being investigated for Miserable Mal-alignment on the basis that my knees hurt when in use and feel like they are "giving way" at least 4 times a day. So I know how you feel. The right hurts much less than the left which can barely support my weight at times but both legs appear to be rotated away from normal.

Instability is the term used for when your knee either dislocates (fully pops out of the joint) or subluxes (sort've half pops out of joint).  According to my OS the "giving way" feeling is actually your brain telling the muscles in your legs to relax because it feels what your doing will cause injury. I got the impression that this is because of the mal-alignment but others may experience the same but for a different reason. In my case the knee cap feels like it isn't where it should be and needs to be "scooped" back into position. It moves so freely that it feels as if there's no support from the surrounding soft tissue, giving the impression of a dislocation without the damage!

Hope this helped. x

It may also be that one leg is fine, and the other has the problem.  Favoring one leg overworks the other.

I have a normal right knee, rotational CT scans, MRI, all sorts of x-rays and manual test were done by a top-notch specialist for patellofemoral disorders.  There was nothing found wrong with my right.

My left leg had a torn MPFL and lateral release messed things up more.   I started developing pain on the outside of my right knee.   I was twisting, turning, leaning on it all the time and eventually that lead to pain.

Now that the left is fixed, my right knee is feeling much more normal.  I am hopeful it is a matter of time before both knees settle down.

Thanks for the responses! The explanation of the knee giving way because it's the brain telling the muscles to relax since it's doing something it doesn't like is a great explanation! Both legs are pretty obviously twisted, so it's hard to say if one is over compensating for the other, but I definately know my left knee is unstable. I swung a grocery bag against my left thigh yesterday (filled with bread and deli meats) and that made my knee buckle. Anyway, all your answers are much appreciated! Less than a month til I see Dr. Teitge:)
