Local infiltration analgesia in hip and knee arthroplasty: an emerging technique.

The optimal form of post-operative analgesia in hip and knee arthroplasty is still debated. Traditionally, patient-controlled analgesia and epidural anaesthesia were used. Potential side-effects such as nausea, confusion, urinary retention, hypotension and immobility have resulted in the emergence of newer techniques that limit opioid use. Peripheral nerve blockade provides excellent analgesia but limits patient ability to ambulate in the immediate post-operative period. Local infiltrative analgesia (LIA) is an emerging technique that has shown to provide superior analgesia, higher patient satisfaction and earlier discharge from hospital when compared to some of the more traditional methods. This review article highlights the advantages of LIA in hip and knee arthroplasty surgery. We describe the technique used, including additional measures that aid early ambulation and discharge from hospital in this cohort of patients.
