Spine - It's not my knees! It’s the spine!

Now 6 years after having my R TKR then a revision, then a L TKR, and 10 months after that, I am still having stiffness, pain, reduced ROM & more-in both knees. On a suggestion, I recently had an MRI on my lower back & discovered that I have a Lumbar Spinal Stenosis which is (probably) responsible for all the symptoms I have had over the past 1-6 years. I may not have needed the Revision. So now I am searching for a reliable Spinal surgeon to perform Spinal surgery to correct my Stenosis. Here's hoping that I will finally be able to return to normal activities, gardening, golf, & other. Any recommendations from readers for a Surgeon or Clinic?
