Comparative analysis of influence of adductor canal block and multimodal periarticular infiltration versus adductor canal block alone on pain and knee range of movement after total knee arthroplasty: a prospective non-randomised study

Purpose Pain management after total knee arthroplasty has seen many recent advances such as peripheral nerve blocks in order to improve the functional outcome and reduce morbidity after surgery. Adductor canal block (ACB) and multimodal periarticular infiltration (MPI) are two techniques that have been proven to be efficacious individually. We hypothesized that the combination of ACB with MPI would reduce pain and improve knee range of movement (ROM) compared to ACB alone.
