BACKGROUND AND OBJECTIVES Both clonidine and ketamine have been found to prolong the action of local anesthetics through a peripheral mechanism. Our study compares the efficacy of a low dose of clonidine or ketamine separately added to intravenous regional anesthesia (IVRA) with lidocaine to prevent tourniquet pain. METHODS We conducted a prospective(More)
The optimal fixation of the Rotaglide total knee arthroplasty’s (TKA) components is controversial. It is hypothesized that the hybrid fixation (cementless femoral component) in a mobile-bearing TKA system might cause increased rate of loosening—especially in the femoral part—and finally failure of the arthroplasty. Consequently, the aim of this study was to(More)
It is questionable how much of the PCL is really preserved following a complete transverse tibial cut during a cruciate-retaining (CR) total knee arthroplasty (TKA). It is hypothesized that a complete transverse tibial cut jeopardizes the PCL tibial insertion during a common CR TKA. Thus, the aim of the present study was to assess intraoperatively the(More)
