Experimental: Adductor canal block
Patients in this arm will receive an adductor canal block prior to undergoing a medial compartment knee arthroplasty.
Procedure: Adductor canal block
Other Name: Saphenous nerve block
Active Comparator: Lumbar plexus block
Patients in this arm will receive a lumbar plexus block prior to undergoing a medial compartment knee arthroplasty.
|Procedure: Lumbar plexus block|
- Verbal pain scores at 6 hours post nerve blockade. [ Time Frame: 6 hours post block. ]Comparison of verbal numerical pain scores at rest and with movement over the first 24 hours following nerve blockade.
- Opioid consumption [ Time Frame: 24 hours ]Comparison of opioid consumption over 24 hour period between adductor canal block and lumbar plexus block.
- Time to first analgesic [ Time Frame: 24 hours ]Time to first analgesic between two groups: adductor canal block and lumbar plexus block.
- Opioid related side effects [ Time Frame: 24 hours ]Occurrence of opioid related side effects (nausea, vomiting and itching) between two groups: adductor canal block and lumbar plexus block.
- Quadriceps motor strength [ Time Frame: 6 hours ]Comparison of quadriceps motor strength at 6 hour post nerve block between two groups: adductor canal block and lumbar plexus block.
