Study summary

Adductor canal block is an effective analgesic technique for major knee surgery. However, the saphenous nerve block is not sufficient to explain this block's efficiency. It has been shown that adductor canal block can spread to the tibial and fibular nerves through the adductor hiatus. However, this diffusion's frequency has never been measured. The main objective of this study is to assess clinically the frequency of the spread of the adductor canal block to the fibular and tibial nerves.

Inclusion Criteria: * patients over 18 years old scheduled for elective knee surgery under general anesthesia * in our center * receiving an adductor canal block Exclusion Criteria: * patients cognitively impaired, * patients suffering from peripheral neuropathy at the lower limb, * patients receiving an IPACK block or surgical knee infiltration to complete the adductor canal block analgesia. * patients who refused to take part in this study * pregnant or breastfeeding patients * patients under guardianship * imprisoned patients, * patients without any medical insurance

Primary outcome measure(s)

  • Frequency of local anesthetic's spread to tibial and fibular nerve — at 4 hours
    The primary outcome is the frequency of local anesthetic's spread to tibial and fibular nerve during an adductor canal block, assessed by sensory and motor testing of these nerve territories. Sensorimotor testing will be performed at four hours with loco-regional anaesthesia.
