Patent number: 8282685Abstract: This surgical apparatus comprises, on the one hand, means for spatial marking-out of the kneecap and femur of a patient to be operated on, and, on the other hand, means for simultaneous and relative representation of this kneecap provided virtually with a patellar implant of the prosthesis, and of this femur provided virtually with a femoral implant of the prosthesis, in a sagittal plane passing both through the kneecap and through the trochlea of the aforementioned femoral implant. Using this apparatus, the surgeon can easily and quickly check the antero-posterior size of the prosthesis in order to reduce the risks of subsequent dislocations of the kneecap fitted with the prosthesis.Type: GrantFiled: April 11, 2006Date of Patent: October 9, 2012Assignee: Tornier SASInventors: Olivier Rochetin, Yves-Alain Ratron, Alain Tornier

Patent number: 8002839Abstract: This surgical apparatus comprises, on the one hand, means for spatial marking-out of the patella and femur of a patient to be operated on, and, on the other hand, means for simultaneous and relative representation of this patella provided virtually with a patellar implant of the prosthesis, and of this femur provided virtually with a femoral implant of the prosthesis, in a transverse plane passing both through the patella and through the trochlea of the aforementioned femoral implant. Using this apparatus, the surgeon can easily and quickly check the congruent position of the patellar implant with respect to the prosthetic femoral trochlea in order to reduce the risks of subsequent dislocations of the patella fitted with the prosthesis.Type: GrantFiled: April 11, 2006Date of Patent: August 23, 2011Assignee: Tornier SASInventors: Olivier Rochetin, Yves-Alain Ratron, Alain Tornier

Publication number: 20110046685Abstract: Surgical instrumentation according to embodiments of the present invention may be configured to permit a surgeon to adjust external rotation of a femur according to two or more adjustment criteria selected from the group consisting of: (a) peroperative measurement of a value of the external rotation; (b) setting the external rotation to a preoperatively predetermined rotation value; (c) a position of a Whiteside line; (d) a position of a biepicondylar line; and (e) a position of an internal condyle.Type: ApplicationFiled: July 26, 2010Publication date: February 24, 2011Inventors: Eric FAURE, Olivier ROCHETIN

Patent number: 7544211Abstract: A low-profile offset stem tibial implant includes a tray with a plate that extends transversely around a first tibial axis. The plate includes a distal surface adapted to engage against the prepared surface of the tibia. An engagement portion extends away from the distal surface of the plate substantially along the first tibial axis. A stem is provided with a distal end adapted to be introduced into the medullary canal of the tibia along a second tibial axis and a proximal end. One or more adapter elements are provided with a proximal portion sized to engage with the engagement portion of the plate along the first tibial axis. The adapter element also includes a distal portion adapted to engage with the proximal end of the stem along the second tibial axis. The adapter element permits adjustment of the medio-lateral and antero-posterior position of the second tibial axis relative to the first tibial axis.Type: GrantFiled: February 1, 2007Date of Patent: June 9, 2009Assignee: TornierInventor: Olivier Rochetin

Patent number: 7468077Abstract: The distal end part of the retractor according to the invention is provided both with terminal tips for abutment on one of the femoral condylar walls which define therebetween the intercondylar space, and with a wing extending laterally in projection from this end part in order to form a frontal surface for thrust, in a medial-lateral direction, of that part of the quadriceps muscle tendon containing the patella when the tips are in abutment in the intercondylar space. By using this retractor as a lever, the wing efficiently reclines the patella, without turning it completely on itself, entirely exposing one of the femoral condyles. This invention is more particularly applicable to a surgical procedure for implanting a unicompartmental knee prosthesis.Type: GrantFiled: August 2, 2005Date of Patent: December 23, 2008Assignee: Tornier SASInventor: Olivier Rochetin
