Official Title: Ideal Anatomic Location for Saphenous Nerve Blocks: A Prospective Clinical Evaluation

Brief Summary: 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.

Detailed Summary: 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.

Current Primary Outcome: knee extensor strength measured in kilograms [ Time Frame: change from baseline preoperatively to 30 minutes after nerve block placement ]

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


Original Primary Outcome: Same as current

Current Secondary Outcome:

  • pain level [ Time Frame: change from baseline preoperatively to two weeks post-operatively ]
    Pain relief will be measured by review of the medical record for type and amount of pain medications used
  • quality of life assessment [ Time Frame: change from baseline preoperatively to two weeks post-operatively ]
    PROMIS Global Health Survey will be completed by patients in both treatment arms pre-operatively and again two weeks post-operatively


Original Secondary Outcome: Same as current
