NCT02249481

Brief Summary

Open-labelled, randomised controlled trial. Patients will be assessed pre-operatively, at 24 and 48 hours for the primary outcome and secondary outcomes (except for Oxford Knee Score which will be assessed pre-operatively and at 6 months post-operatively by the ortho-paedic team). Primary Objective: To demonstrate whether adductor canal nerve infusions result in superior patient mobilisation within the first 48 hours following total knee replacement compared to femoral nerve catheter infusions. Secondary Objective: To identify whether adductor canal nerve infusions result in superior analgesia within the first 48 hours following total knee replacement compared to femoral nerve catheter infusions.

Outcome Measures

Primary Outcomes (2)

  • Timed Up Go (TUG) test

    This measures the time (in seconds) taken by a patient to rise to their feet from a sitting position, walk 3 metres in a straight line, turn around, walk back to the seat and sit down again.

    24 hours post-op

  • Timed Up Go (TUG) test

    This measures the time (in seconds) taken by a patient to rise to their feet from a sitting position, walk 3 metres in a straight line, turn around, walk back to the seat and sit down again.

    48 hours post-op

Secondary Outcomes (5)

  • Total opiate consumption

    48 hours post-op

  • Visual Analogue Score (VAS) for pain

    24 and 48 hours post-op

  • Range of knee flexion

    24 and 48 hours post-op

  • Maximum Voluntary Isometric Contraction (MVIC)

    24 and 48 hours post-op

  • Oxford Knee Score (OKS)

    Pre-op, and at 6 months post-op

Study Arms (2)

Group F

ACTIVE COMPARATOR

Femoral nerve catheter delivering 0.0625% L- Bupivacaine: Blockade at level of Femoral crease. Identify femoral nerve. In plane lateral approach. Bolus 20 mls via needle. Catheter threaded and 2-4cm left in situ (bevel orientated cephalad).and 5 mls injected via catheter to confirm spread under ultrasound guidance. Glue/Lockit dressing.

Procedure: Femoral nerve catheter delivering 0.0625% L- Bupivacaine

Group A

EXPERIMENTAL

Adductor canal catheter delivering 0.0625% L- Bupivacaine: Blockade at mid-thigh. Identify sartorius at mid thigh - find point where the femoral artery begins to descend from sartorius. In plane technique, hydro-dissect space between sartorius and femoral artery. Catheter threaded and 2-4cm left in situ (bevel orientated cephalad). Bolus 20 mls via needle and 5 mls via catheter to confirm spread under ultrasound guidance. Glue/Lockit dressing.

Procedure: Adductor Canal catheter delivering 0.0625% L- Bupivacaine

Interventions
