Previous studies reporting an incidence of obturator nerve block after three-in-one block may have mistaken a femoral nerve block for an obturator nerve block in 100% of cases when the cutaneous distribution of the obturator nerve was assessed on the medial aspect of the thigh. The only way to effectively evaluate obturator nerve function is to assess adductor strength.

All 3 strategies provided effective pain relief. PCFA resulted in a lower consumption of ropivacaine (toxic and financial impact). PCFA + Inf does not improve postoperative analgesia.

This study was registered at ClinicalTrials.gov, identifier NCT02940847.
