  • Patent number: 6514287
    Abstract: A modular glenoid assembly is provided for attachment to a glenoid surface of a scapula. The modular glenoid assembly includes a base adapted to couple with the glenoid surface and a bearing insert. The base includes a lip that defines a channel. The bearing insert includes a bearing surface adapted to engage a head portion of a humeral component and a tab. The tab is formed to be received within the channel and engage the lip when the insert is moved in a superior direction into position against the base.

  • Patent number: 5147405
    Abstract: 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.
