Conditions
Brief summary
The purpose of this study is to compare blockade of the adductor canal and the posterior branch of the obturator nerve to blockade of the femoral nerve for patients undergoing arthroscopic anterior cruciate ligament reconstruction. The primary outcome is pain, measured as opioid consumption and pain scores during the first 24 postoperative hours. The secondary outcome is quadriceps strength.
Interventions
Adductor canal plus obturator posterior nerve blocks as part of anaesthetic for arthroscopic anterior cruciate ligament reconstruction. Adductor canal block performed using 7.5ml of 0.75% ropivicaine. Obturator posterior nerve block performed using 7.5ml of 0.75% ropivicaine, and performed at the same time as the adductor canal block. Both injections were single dose perineural injections via a 21-G, 100 mm long SonoPlex needle, and performed with ultrasound guidance (Sono-Site M-Turbo ultrasoun

Adductor canal block performed using 7.5ml of 0.75% ropivicaine. Obturator posterior nerve block performed using 7.5ml of 0.75% ropivicaine, and performed at the same time as the adductor canal block. Both injections were single dose perineural injections via a 21-G, 100 mm long SonoPlex needle, and performed with ultrasound guidance (Sono-Site M-Turbo ultrasound unit) in an operating theatre during monitored anaesthetic care prior to the start of surgery. Examination of fidelity to the intervention undertaken via examination of the anaesthetic record (scanned paper copy available on electronic patient health record).
