What is the effect of treating people with knee or hip osteoarthritis who have concurrent lumbar spinal stenosis?

The effect of treating people with osteoarthritis of the knee or hip who have concurrent lumbar spinal stenosis (LSS) is unknown. This study investigated the relationship between the presence of LSS symptoms and changes in pain, function, and quality of life after participation in a GLA:D® knee or hip course.

6813 patients from the GLA:D® database were included in the study. They were classified with LSS symptoms based on self-reported symptoms and differences in pain, function, and quality of life scores were assessed at 3 and 12 months.

15% (knee osteoarthritis) and 23% (hip osteoarthritis) of the participants respectively had concurrent LSS symptoms. There was no difference in improvement after treatment in terms of knee- or hip-related pain, function, and quality of life for patients with and without concurrent LSS symptoms. Patients with knee osteoarthritis or hip osteoarthritis who also have LSS symptoms should be able to expect the same improvements in knee or hip-related pain, function, and quality of life outcomes as osteoarthritis patients without LSS symptoms when undergoing a GLA:D® course of patient education and training.
