About

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.

Full 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.

Enrollment: 30 patients

Sex: All

Ages: 18 to 65 years old

Volunteers: No Healthy Volunteers

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
