I am 72 and have grade 1 “approaching” grade 2 Spondylolisthesis at L4/L5 and L5/S1. Also arthritis and degenerative disc disease. I’ve had three epidurals which seemed to help pain in the side of one leg and am getting PT (basic lumbar program.) I do not get any numbness or tingling - just an achy lower back on and off but I DO have persistent and stabbing pain in the back of my knee; worsens with walking and especially bending it to climb up the steps to the house after a walk, for example. I’ve seen my MRIs and I know where my nerves are compressed. I assume the spine issues are the root of the knee pain although that knee has had a meniscus repair over 10 years ago and has been wonky for years. O know it’s not a Baker’s cyst. This is really my major and almost only symptom. Does anyone else experience this?
