This research is being done to compare two different saphenous nerve block locations and will help to determine which site best maintains knee strength and pain control.
This is a prospective, randomized, observer blinded clinical trial comparing motor strength in knee extension between two sets of patients, one receiving a proximal thigh block of the saphenous nerve and one receiving a distal thigh block of the saphenous nerve. The secondary objectives are to compare the pain relief and quality of life of participants in these two groups.

A nerve block will be performed by the anesthesiologist. The location of the nerve block will be per randomization envelope (proximal vs. distal) and performed just prior to foot or ankle surgical procedures that require a saphenous nerve block

knee extensor strength measured in kilograms
Strength of the knee extensors in both treatment arms (distal vs. proximal block) will be tested preoperatively and again 30 minutes after the nerve block by using a hand-held dynamometer measured in kilograms
Time frame: change from baseline preoperatively to 30 minutes after nerve block placement
pain level
Pain relief will be measured by review of the medical record for type and amount of pain medications used
Time frame: change from baseline preoperatively to two weeks post-operatively
quality of life assessment
PROMIS Global Health Survey will be completed by patients in both treatment arms pre-operatively and again two weeks post-operatively
Time frame: change from baseline preoperatively to two weeks post-operatively
