Adductor Canal Block and Effect of 10 Versus 30 ml Ropivacaine on Muscle Strength: a Randomized Study in Healthy Volunteers

Adductor Canal Block and Effect of 10 Versus 30 ml Ropivacaine on Muscle Strength: a Randomized Study in Healthy Volunteers

To investigate whether reducing the volume (30 versus 10 ml) ropivacaine injected can reduce the number of subjects with impaired muscle strength following adductor canal block. We hypothesized that adductor canal block with 10 ml 0.1% ropivacaine preserves quadriceps strength compared with an adductor canal block with 30 ml.
