Patent number: 9439660Abstract: A method of, and apparatus for, arthroplasty of a knee joint comprising obtaining a desired spacing of the femur from the tibia by inserting a spacer into the knee joint between the femur and the tibia. The spacer is used as a reference for securing a guide jig in position about the knee joint for guiding resection of one or both of the femur and tibia for fitting of tibial and/or femoral prostheses. A method of resecting the femur while moving the tibia through an arc of motion to remove bone to the desired depth, a method of determining the position of the guide jig, the guide jog, an alignment device and the spacer are also described.Type: GrantFiled: April 7, 2014Date of Patent: September 13, 2016Assignee: Smith & Nephew, Inc.Inventors: Leo Arieh Pinczewski, Stephen John Parker, Greg Marik, Richard A. Rocco

Patent number: 6969393Abstract: A cutting device for being inserted into a knee joint between the tibia and the femur, wherein the cutting device is adapted for resecting bone from the femur to a desired depth in a path of travel of the tibia when located in the knee joint and operated as the tibia is moved through an arc of motion about the femur between backward and forward positions. A cutting device is also disclosed for being inserted into a knee joint between the tibia and the femur for resecting bone from the tibia to a desired depth to form a recess in a condyle of the tibia for reception of a tibial implant, comprising a body being located between the tibia and the femur, a cutter for resecting the bone from the tibia to form the recess and a drive mechanism for driving the cutter to resect the bone and being arranged in the body, wherein the cutter is mounted on the body and protrudes therefrom for resecting the bone from the tibia.Type: GrantFiled: September 10, 2002Date of Patent: November 29, 2005Assignee: Smith & Nephew, Inc.Inventors: Leo Arieh Pinczewski, Stephen John Parker, Greg Marik, Richard A.
