Abstract
There has been a widespread appreciation on the part of both patients and surgeons that pain control following total knee replacement is an important goal. The concepts of both preemptive analgesia and multimodal pain protocols have become increasingly popular. In addition to these ideas, surgeons continue to utilise adjunctive treatments such as peripheral nerve blocks and periarticular injections. Multiple studies demonstrate the efficacy of these therapies. Several authors have published different “cocktails” for their periarticular injections in an attempt to help delineate which components of the cocktail are most important. In addition to deciding on a correct cocktail, how it is delivered is important.
This video will demonstrate a technique that increases the likelihood that the injected solution is placed in the appropriate areas and does not simply bath the tissues. Important components of the technique include the use of a small gauge needle (22) and a control syringe to insure proper placement as well as an aim to target the injections into the periosteum of the femur and tibia and the posterior capsule primarily.
