Continuous Versus Intermittent Sciatic Block for Total Knee Arthroplasty

Continuous Versus Intermittent Sciatic Block Combined With a Continuous Femoral Block for Patients Undergoing Total Knee Arthroplasty: a Prospective, Randomized Trial.

The role of a sciatic block in addition to a femoral block remains controversial. The study addresses this topic by comparing a continuous block versus an injection on demand.

Inclusion Criteria:

• Patients scheduled for total knee arthroplasty

Exclusion Criteria:

• failure to establish femoral and sciatic block
• insufficient analgesic effect of the block
• patient declines to participate
