Brief Summary
Adductor canal block is commonly offered to provide pain relief following knee surgery with the hope that they cause less leg weakness than traditionally performed femoral nerve block. Infrequently, adductor canal blocks also result in leg weakness thereby potentially limiting the advantages of the technique. Investigators want to find out the effective dose for a 30% response (volume of local anesthetic which would result in clinically significant weakness of the leg)

Outcome Measures
Primary Outcomes (1)
The primary outcome will be the EV50 of anesthetic volume needed to produce >30% reduction of pre-injectate quadriceps strength at 20 minutes following adductor canal block.
Measured by handheld dynamometer
Percentage difference before block and at 20minutes
Secondary Outcomes (2)
Reduced sensation to pin-prick around the anteromedial aspect of the knee
20 minutes post-block
Post-operative quadriceps muscle function
Percentage difference before block and at 4 hours following block
Study Arms (1)
Knee arthroscopic patient
EXPERIMENTAL1\) Male and females 2) Age 16-60 years 3) Scheduled surgery 4) Knee arthroscopy 5) ASA Class I - III Volume finding study to follow up-and-down design using a single cohort of patients. Intervention of patient will be dependent on effect of previous patients dose of and response to Ropivacaine 0.5% injectate.
Interventions
Varying volume according to motor response of previous subject
