Publisher Description

There are a variety of techniques used in the management of postoperative pain after total knee arthroplasty. Single-shot regional blocks provide good pain control in the immediate postoperative period but rarely persist beyond 24 hours. The efficacy of continuous femoral nerve infusion over opioid regimens is well-established and approximates that of epidural infusion for postoperative analgesia (1,2). It has advantages over the epidural route with a reduced level of 'complexity' of care, complications and easier mobilisation, especially of the non-operative side. Continuous wound instillation with local anaesthetic has enjoyed some popularity for many procedures with the advent of reliable elastomeric pumps and multi-hole catheters. A potential advantage of intra-articular infusion of local anaesthetic is that it allows early physiotherapy without motor blockade of the quadriceps muscle. However, its efficacy is yet to be established. A retrospective study involving intra-articular infusion of local anaesthetic after knee arthroplasty yielded encouraging results with reduced opioid consumption but did not involve any regional anaesthetic technique (3).
