I have constant pain, including locking feeling and stiffness, in lower back, radiating to left leg and foot. I cannot stand or walk very long, but sitting is fine. Sleeping comfortably is difficult. I had two epidural shots last summer, but pain still exists. I also tried chiropractic help, but that seemed to make it worse. I am currently trying PT but have no relief yet. I had a left knee replacement in January. Could the tkr be aggravating my back or is my back the real problem? I did have back pain before knee replacement My tkr seems to be healing appropriately, with normal ROM and flexion, but with occasional stiffness and pain. I have played tennis for the last 30 years, up until November. Knee pain and back pain caused me to stop playing. I am a 55-year-old female. I’m desperate for relief and not sure what to do. I appreciate your opinion.
Here are my MRI findings:
1. Lumbosacral transitional vertebral body. The vertebral bodies demonstrate normal height. Minimal degenerative endplate change is noted throughout the lumbar spine.
2. Disc desiccation at all lumbar levels. There is minimal impingement upon the anterior the al sac. It no nerve root impingement or displacement. Minimal circumferential disc bulging with associated osteophytes at L1-2, L2-3, L3-4, L4-
3. At L5-S1, there is 1 mm anterior spondylolisthesis which is degenerative. Mild circumferential disc bulging is present. There is indentation upon the anterior thecal sac and mild bilateral neural forminal narrowing. A 5 mm synovial cyst is present within the right posterolateral aspect of the spinal canal adjacent to the degenerated facets and is decreased in size compared to the August 2016 report. A 3 mm synovial cyst is present within the left posterolateral aspect of the spinal canal is also decreased in size compared to the August 2016 report. The spondylolisthesis, disc bulge and facet degenerative change and ligamentum flavum hypertrophy create borderline central canal stenosis canal stenosis. The conus medullaris is unremarkable and resides posterior to L1-2.You don’t explain the difference in pain in your back vs. leg and this could be an important component of your differential diagnosis. Your comment “I cannot stand or walk very long, but sitting is fine” is somewhat telling. This sounds like lateral recess or foraminal stenosis (https://neckandback.com/conditions/lumbar-foraminal-stenosis-collapse/ and https://neckandback.com/conditions/lateral-recess-stenosis/). The slip is caused by degenerative facets (see https://neckandback.com/conditions/degenerative-spondylolisthesis-or-spondlylolysthesis/) and the narrowing probably from the cysts which are common to this condition (https://neckandback.com/conditions/ganglion-cysts/).
The disc height at L5-S1 most likely has diminished significantly with a degenerative spondylolisthesis. The height loss can be significant as the foramen (the exit hole for the nerve root) is made up 60% by the height of the disc. Not only do you lose foraminal height but the annulus (the outside of the disc) will bulge into the foramen just as a car tire that goes flat will push out sideways. The nerve root can be compressed with standing and walking as these actions will narrow the foramen or the lateral recess while bending forward (crouching, leaning on a counter or sitting in a recliner) will open the foramen and recess.
