“…Since the shape and positioning of the replaced patella prosthesis are different with respect to the normal patella, the patella kinematics after TKA are altered under in vivo conditions, quite possibly due to changes in the bearing surface forces generated at the patellofemoral joint (Dennis et al, 1996;Chew et al, 1997;Komistek et al, 2000;Stiehl et al, 2001). Patellofemoral forces have been experimentally estimated using in vitro cadaveric models (Huberti and Hayes, 1984;Ahmed et al, 1987;Miller et al, 1997;Singerman et al, 1999;Browne et al, 2005). Mathematical modeling, both planar two-dimensional (2D) (van Eijden et al, 1986;Yamaguchi and Zajac, 1989;Stienkamp et al, 1993;Cohen et al, 2001;Wallace et al, 2002) and three-dimensional (3D) (Kwak et al, 2000;Neptune et al, 2000;Shahar and Banks-Sills, 2004;Komistek et al, 2005;Powers et al, 2006), has also been used to estimate in vivo forces in the patellofemoral joint.…”

“…Sensors were individually calibrated in the range of 0-500 N which is the expected intraoperative force range for the patellofemoral joint (Singerman et al, 1999). Following individual testing, the sensors were placed in a smart patella arrangement, which allowed for the sensors to be simultaneously loaded and interrogated.…”

“…Some authors finds shows that patient with not resurfaced knees had slightly better satisfaction than patellar resurfaced patients [3,9] and with correctly execution TKA, resurfacing patella is unnecessary [10,13]. But after obtaining good clinical outcomes and because of the possibility of a subsequent deterioration of the patella with osteoarthritis in long-term follow-up, other group of researches consider that resurfacing of the patella during primary total knee arthroplasty is one of the best solution [2,12,16,20].…”

“…In TKA performed without resurfacing, the patella contact force does not significantly increase and cartilage contact stress doesn't increase and this lead to prevent most expected complications [13]. Nevertheless the risk of postoperative complications is highest in patellar resurfacing group than not resurfacing group [3].…”
