Not recommended for total knee arthroplasty













Pre-operative


not recommended


·         Systemic analgesia:


       Alpha-2-delta subunit ligands (gabapentinoids) (Grade D), due to a lack of procedure-specific evidence


       Conventional NSAIDs (Grade B) because of limited procedure-specific evidence and increased risk of bleeding


       Corticosteroids (Grade D) due to a lack of procedure-specific evidence (may be used for reasons other than postoperative analgesia)


       NMDA antagonists


o        Dextromethorphan (Grade D) due to inconsistent evidence of analgesic effects


o        Ketamine (Grade D) because of limited procedure-specific evidence


       Strong opioids (Grade D) due to a lack of evidence for analgesic benefit over postoperative administration


·         Peripheral nerve blocks:


       Combination femoral and obturator block (Grade D) because of limited procedure-specific evidence


       Combination femoral and sciatic nerve block (Grade D) because of limited and inconsistent procedure-specific evidence


       Lumbar plexus block (posterior approach) (Grade D), as femoral nerve block is equally effective and is associated with fewer complications


       Alpha-2-adrenoceptor agonists (clonidine, epinephrine), as part of the LA solution in peripheral nerve blocks (Grade A) due to a lack of efficacy in procedure-specific studies


·         Epidural:


       LA and/or opioid (Grade B) due to an increased risk of adverse events and no improvement in analgesia compared with femoral nerve block


       Ketamine (as adjuvant to epidural) (Grade B) due to side-effects and inconclusive analgesic efficacy


       Tramadol (as adjuvant to epidural) (Grade B) because of insufficient analgesia


·         Spinal:


       Neostigmine (Grade D) because of side-effects and limited procedure-specific evidence


       Clonidine (Grade D) because of limited and inconsistent procedure-specific evidence


·         Intra-articular techniques (Grade D) because of inconsistent evidence


·         Physical therapy (Grade D) based on postoperative analgesic effects alone


Intra-operative


not recommended


·         Systemic analgesia:


       NMDA antagonists


o        Dextromethorphan (Grade D) because of inconsistent analgesia


o        Ketamine (Grade D) due to limited procedure-specific evidence


       Weak opioids (Grade D) due to lack of evidence for analgesic benefit over postoperative administration


·         Peripheral nerve blocks administered intra-operatively (Grade D)


·         GA or spinal anaesthesia without any local or regional analgesic technique (Grade D)


·         Epidural anaesthesia (Grade D) because postoperative epidural analgesia is not recommended


·         Intra-articular techniques (Grade D) because of inconsistent analgesia


·         Drains (Grade A) due to lack of analgesic and other recovery benefits


Postoperative


not recommended


·         Systemic analgesia:


       Alpha-2-delta subunit ligands (gabapentinoids) (Grade D) due to lack of procedure-specific evidence


       Clonidine (Grade D) because of limited procedure-specific evidence


       IV ketamine infusion (Grade D) because of limited procedure-specific evidence


       IM administration of strong opioids (Grade B) due to unfavourable pharmacokinetics, injection-associated pain and patient dissatisfaction


       Weak opioids for high intensity pain (Grade D) due to insufficient analgesic efficacy


       Paracetamol alone for high intensity pain (Grade D) due to insufficient analgesic efficacy


·         Peripheral nerve blocks:


       Combination femoral and obturator block (Grade D) because of limited procedure-specific evidence


       Combination femoral and sciatic nerve block (Grade D) because of limited and inconsistent procedure-specific evidence


       Lumbar plexus block (posterior approach) (Grade D), as femoral nerve block is equally effective and is associated with fewer complications


       Alpha-2-adrenoceptor agonists (clonidine, epinephrine), as part of the LA solution in peripheral nerve blocks (Grade A) due to a lack of efficacy


·         Epidural:


       LA and/or opioid (Grade B) due to an increased risk of adverse events and no improvement in analgesia compared with femoral nerve block


       Ketamine (as adjuvant to epidural) (Grade B) due to side-effects and inconsistent analgesic efficacy


       Tramadol (as adjuvant to epidural) (Grade B) because of insufficient analgesia


·         Intra-articular techniques (Grade D) because of inconsistent analgesia


·         TENS (Grade B) due to limited procedure-specific evidence suggesting a lack of benefit
