I had a full right hip replacement just over a year ago. I was long past due to have it done and was having a lot of groin pain etc. Figured it was due to compensating while walking stairs etc. I love my new hip - it finally for the first time in 20 years doesn t hurt. However I am having residual weakness from the hip to the knee with long periods of sitting or walking - especially in bad shoes. While carrying say groceries up a flight of stairs if I lead with my bad leg I most often will get a very sudden and sharp pain radiating in the general hip area with a loss of balance and falling to a sitting position. PT has helped with muscle strength but not with overall symptons. Trying to omit all possible causes I had an MRI done on the lower lumbar region. results were disc desiccation in L2-L3 L3-L4 and L4-L5; Minimal diffuse disc bulge indents the ventral thecal sac L2-L3, L3-L4 and L4-L5; L4-L5 has mild loss of disc space height with disc desiccation. 2-3 mm degenerative anterior listhesis present of L4 on L5 This in conjucnction with Ligament complex and hypertrophy and prominenet facet join arthropathy result in mild spinal canal stenosis. Mild bilateral neural foraminal narrowing. Does this mean more than arthritis ? I know cause is most likely from all the weird walking and compensating I have been doing for the past 5 years as well as a lot of on my knees cleaning and desk work is also a contributing factor. Treatment ?
