P.S. I was told for my type of spine surgery for lumbar spine (they removed bad discs, fused my vertebrae L3-L5 levels, put in rods and screws to stabilize, etc.), it takes about 3 months to recover from surgery and a full year to notice the full effects and benefits from surgery. I just started physical therapy at 2.5 months post surgery and would hope to notice benefits within 1-3 months. It seems your long recovery even with PT shows there may still be issues with your spine, blood flow and spinal cord/nerve roots that affect your lower body strength. Updated MRIs of your cervical, thoracic and lumbar spine can provide a surgeon with a full view of what it happening structurally and how it ties to your symptoms. The weakness in your legs is similar to what I had with compression in my lumbar spine causing neurogenic claudication. It sounds like you may also still have some vascular claudication. An orthopedic spine specialist/surgeon or neurosurgeon may be able to help pinpoint the cause of your weakness in your legs.
