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)
PURPOSE 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(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)
