摘要： A method and apparatus for performing total knee arthroplasty which is minimally invasive includes components with guide surfaces and slots for controlling the path of a cutting saw. The instrumentation permits resection of the proximal end of the tibia and distal end of the femur to be performed either medially or laterally with minimal cutting of soft tissue.

摘要： A method and apparatus for resectioning a patella without everting it includes a resection guide which grips the patella with gripping members, one of which can also function as an alignment guide for a surgeon using a saw for the resectioning. Means engageable with the resection guide are provided for aligning drills and/or reamers used in resectioning. Under one embodiment, a pair of reamers are provided for reaming the patella in two reaming operations.

摘要： A knee prosthesis is provided including a tibial component having first and second generally concave bearing surfaces and a stabilizing post extending upwardly between the first and second bearing surfaces. The knee prosthesis also includes a femoral component having first and second spaced apart, convexly curved condyle bearing surfaces and a cam surface extending between the first and second bearing surfaces. The femoral component is articulatable with the tibial component between an extended position and a flexed position. The first and second femoral bearing surfaces engage the first and second tibial bearing surfaces, respectively, at first and second contact points. Between the extended position and about a 25.degree. flexion angle, the cam surface is spaced apart from a posterior side wall of the stabilizing post to permit movement of the femoral and tibial component as natural physiology dictates. As the knee prosthesis is flexed at about a 25.degree. flexion angle, the cam surface first engages the posterior side wall of the stabilizing post to control movement of the femoral component relative to the tibial component. Therefore, the stabilizing post engages the cam surface to control the position of the femoral component relative to the tibial component only upon flexion of the femoral and tibial component between about 25.degree. flexion and the flexed position.
摘要翻译：提供了一种膝关节假体，包括具有第一和第二大致凹入的支承表面的胫骨部件和在第一和第二支承表面之间向上延伸的稳定柱。膝关节假体还包括股骨部件，该股骨部件具有第一和第二间隔开的凸起弯曲的髁轴承表面和在第一和第二支承表面之间延伸的凸轮表面。股骨部件可与胫骨部件在延伸位置和弯曲位置之间铰接。第一和第二股骨承载表面分别在第一和第二接触点处接合第一和第二胫骨支承表面。在延伸位置和约25度弯曲角度之间，凸轮表面与稳定柱的后侧壁间隔开，以允许股骨和胫骨部件沿着自然生理学规定运动。当膝关节假体以约25度弯曲角度弯曲时，凸轮表面首先接合稳定柱的后侧壁，以控制股骨部件相对于胫骨部件的移动。因此，只有在股骨和胫骨部件在约25°屈曲和屈曲位置之间弯曲时，稳定柱接合凸轮表面才能控制股骨部件相对于胫骨部件的位置。
