Additionally, the geometry of the implant device in anterior-posterior and medial-lateral directions, among other directions, provides a variety of improvements relative to currently available devices.Type: ApplicationFiled: May 16, 2017Publication date: April 25, 2019Inventors: Christopher Ray Cyko, Jason Sean Jordan

Publication number: 20190117407Abstract: The present disclosure discloses an artificial femoral prosthesis (100) for knee arthroplasty, a tibial prosthesis (150), a medial femoral unicompartmental prosthesis (201), a lateral femoral unicompartmental prosthesis (301), and a femoral trochlear prosthesis (401). The femoral prosthesis (100) comprises: a medial condyle portion (51) and a medial trochlear portion (131), wherein an articular surface of the medial condyle portion appears in a sagittal section as an arc of a first ellipse (38), and an articular surface of the medial trochlear portion appears in the sagittal section as an arc of a second ellipse or circle (40); and lateral members (91, 141), comprising a lateral trochlear portion (141) and a lateral condyle portion (91), wherein an articular surface of the lateral trochlear portion appears in the sagittal section as an arc of a third ellipse or circle (80), and an articular surface of the lateral condyle portion appears in the sagittal section as an arc of a fourth ellipse (78).Type: ApplicationFiled: March 28, 2017Publication date: April 25, 2019Inventor: Chen Yang
