Letter to the Editor: Study of Patients with Bilateral Knee Osteoarthritis Undergoing Total Knee Replacement Procedure with Coexisting Lumbar Spondylosis Symptoms

摘要

We have read the article by Londhe et al. 1 entitled “Studyof patients with bilateral knee osteoarthritis undergoingtotal knee replacement procedure with coexisting lumbarspondylosis symptoms” with great interest and congratulatethe authors for this thought-provoking topic; however,there are a few queries that need to be addressed:1. How did you prevent the possible confounding of theOswestry Disability Index (ODI) by knee osteoarthritispain 2?2. ODI was moderate to severe preoperatively in all patients,then why was spine not addressed first? How didthe ODI decrease after total knee replacement?3. Was any correlation between ODI and Oxford KneeScore checked?4. How was the possible selection bias towards advancedosteoarthritis as compared to lumbar spine degenerationaddressed in the study?5. Is it possible that the incidental finding of lumbar degenerationlead to better scrutiny and treatment ofspine symptoms in these patients.
