posteromedial corner?

[CP]

I'm >1 yr post injury (original diagnosis:  complete ACL and MCL, partial PCL, medial meniscus) and >1yr post ACL recon (allograft, menisectomy, lateral release).  I've been having continued super sensitivity to any outward force on  my foot when my knee is bent - went to new OS and he thinks that in my initial injury I also tore my posteromedial corner and did a lot of damage to the soft tissues of my knee - the good news is that the MRI indicates all the main ligaments are intact and there has been no new cartilage damage.  He said my injury sounds like a spontaneously reduced dislocation, and it could take up to 2 years for things to fully heal up.  His recommendation is to continue to protect my knee by using my brace for running and field work (I'm an ecologist) and give things an additional 6 mo to heal and settle down.  If its still bothering me at that time, it might be time to consider doing something about the posteromedial corner.  
I've found virtually nothing on the web about the posteromedial corner - can anyone here shed any light on this part of the knee or recommend any good references?  Any comment on this new OS's plan of action?  Thanks!

read my reply to the post on the posterolateral corner.  I'll check around with a couple of OSs that I know and see what they recommend

Great - thanks a bizillion.  It realy helps me to have a good understanding of the mechanics of what's going on and this has left my basic knee-ligament-function understanding in the dust.

I am having a pretty hard time really finding anything relating to a posteromedial instability.  Here is what is in the AT "bible" (Starkly and Ryan- Eval of Ortho and Sports injuries) describes.
With a PMRI the medial tibial plateau will subluxate posterior on the femur.  The axis of rotation of the knee is then moved from the normal center orientation to an anterolateral postition which results in abnormal internal tibial rotation.  The structural instability is located within the posterior cruciate ligament, posterior oblique ligament, medial collateral ligament, semimembranosus (medial hamstring), anteromedial capsule.

Thanks - that helps me visualize what's going on a bit.  I really appreciate your efforts to find something on this!

If you can give me your e-mail I can e-mail you can illustration concerning the Axis of rotation that I was talking about.

That would be great - a picture would help a lot.  I'm at sopchoppy1@msn.com
Thanks again for all your help!

IN 2004 I had my PCL and LCL replaced and the knee is so much more solid than the non injured knee.

My career is in riding horses and I know because of arthritis I will need a knee replacement but I have awesome stability

Also some gruesome scars from the PCL and LCL and a good staph story ;-)
