Lumbar Epidural Corticosteroid Injection Reduces Subacute Pain and Improves Knee Function in the First Six Weeks After Total Knee Arthroplasty A Double-Blinded Randomized Trial

摘要

Background: Pain control immediately following total knee arthroplasty (TKA) has been a focus for orthopaedists. However, control of subacute pain, which may persist up to 3 months, is usually not optimized. The efficacy of epidural corticosteroids in reducing pain after surgery is documented, but data on their efficacy in controlling subacute pain after TKA are lacking. Our aim was to investigate the efficacy of an epidural corticosteroid in controlling pain in the first 3 months following TKA using a double-blinded randomized clinical trial.
