简要总结
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.
详细描述
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.

研究组 & 干预措施
Proximal saphenous nerve block
The anesthesiologist will administer a saphenous proximal nerve block if specified in the randomization envelope.
干预措施: Saphenous Nerve Block (Procedure)
Distal saphenous nerve block
The anesthesiologist will administer a saphenous distal nerve block if specified in the randomization envelope.
干预措施: Saphenous Nerve Block (Procedure)
结局指标
主要结局
knee extensor strength measured in kilograms
时间窗: 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
次要结局
- quality of life assessment(change from baseline preoperatively to two weeks post-operatively)
- pain level(change from baseline preoperatively to two weeks post-operatively)
