March 30, 2015 updated by: Kreiskrankenhaus Dormagen

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.
