Cementing the femoral component in total knee arthroplasty: Which technique is the best?

Although several techniques exist for cementing the femoral component in TKA, no data are available on which is the best one to use.We therefore compared four cementing techniques in an anatomical open pore sawbone model (n = 20), in order to investigate the influence of cementation technique on overall cement penetration as well as length of the cement mantle over the different cuts.The technique which included cement application onto the anterior and distal bone surfaces, as well as the posterior flanges of the prosthesis, was statistically superior to the other techniques. We therefore advocate this technique as the standard for cementing the femoral component.
