I have been in the Army now for 2 years, been passed through AIT after passing MOS classes while being diagnosed with an oblique tear of the posterior horn of my lateral meniscus through an MRI. When sent to my permanent duty station I was told nothing was torn, and had arthroscopic surgery to remove cartilage and debris floating throughout my knee. This was back in June of 2011, originally diagnosed in Oct 2010, been on profile since Oct 2010. Now have been referred to an MEB. Still not able to walk down or up stairs without holding the rail, cannot run or jog, or do sit ups without extreme pain and unstable shaky feelings. Knee gives out occasionally and have immense pain and discomfort sitting at my desk. Job is MI and am needed to be deployable. What are the chances my MEB is successful and what percentage should i expect to see, as along with the chronic pain and favoring of my injured knee, I am now experiencing terrible back pain and hip pain. I have also completed 8 months physical therapy with symptoms continuing. Can anyone offer advise or information on what I should expect to happen from this process?
