BackgroundWhether cementless fixation on femoral and tibial components increases blood loss during total knee arthroplasty (TKA) is unclear.The purpose of this randomized controlled Oven Select Switch trial was to compare blood loss and early functional recovery between patients who underwent cementless or cemented TKA.MethodsBetween November 2021
Brillouin and Raman scattering spectroscopy are established techniques for the nondestructive contactless and label-free readout end table of mechanical, chemical, and structural properties of condensed matter.Brillouin-Raman investigations currently require separate measurements and a site-matched approach to obtain complementary information from
