Methods of hamstring muscle injection of botulinum toxin type Acombined with periarticular injection after total knee arthroplasty

Abstract

This study aimed to report on a method for injecting botulinum toxin type A into the hamstring muscles combined with periarticular injection in total knee arthroplasty (TKA) patients. We enrolled patients who underwent elective unilateral TKA at our hospital from February 2021 to December 2021 and administered botulinum toxin type A hamstring muscle injection combined with periarticular injection.We established and reported a detailed method for this combined approach, which could provide an alternative analgesic regimen after TKA in clinical practice.
