Tibial articular cartilage plays the important role of transmitting forces through the knee joint; however, we most often study it without any applied loads. The aim of this work was to assess the repeatability of T2 relaxation time maps in the unloaded and loaded knees of five healthy participants. Using qDESS, it is possible to obtain repeatable, in vivo T2 relaxation time maps of the entire tibial cartilage surface as well as inside and outside regions of tibiofemoral contact in both unloaded and loaded knees.
