About this trial
This is an interventional treatment trial for Foot Injury focused on measuring Adult, nerve blocks in foot and ankle surgery, saphenous
Eligibility Criteria
Inclusion Criteria:
- Age 18-65
- Upcoming elective foot or ankle surgery
Exclusion Criteria:
- Preoperative weakness in knee extension
- Documented neuropathy
- Previous knee surgery
- Inability to provide informed consent
Sites / Locations

Arms of the Study
Arm 1
Arm 2
Arm Type
Active Comparator
Active Comparator
Arm Label
Proximal saphenous nerve block
Distal saphenous nerve block
Arm Description
The anesthesiologist will administer a saphenous proximal nerve block if specified in the randomization envelope.
The anesthesiologist will administer a saphenous distal nerve block if specified in the randomization envelope.
Outcomes
Primary Outcome Measures
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
Secondary Outcome Measures
pain level
Pain relief will be measured by review of the medical record for type and amount of pain medications used
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

5. Study Description
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 Description
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.

Arm Title
Proximal saphenous nerve block
Arm Type
Active Comparator
Arm Description
The anesthesiologist will administer a saphenous proximal nerve block if specified in the randomization envelope.
Arm Title
Distal saphenous nerve block
Arm Type
Active Comparator
Arm Description
The anesthesiologist will administer a saphenous distal nerve block if specified in the randomization envelope.
Intervention Type
Procedure
Intervention Name(s)
Saphenous Nerve Block
Intervention Description
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
Primary Outcome Measure Information:
Title
knee extensor strength measured in kilograms
Description
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
Secondary Outcome Measure Information:
Title
pain level
Description
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
Title
quality of life assessment
Description
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
