Embodiment Construction

[0030] While the concepts disclosed herein are susceptible to various modifications and alternative forms, certain typical embodiments thereof have been shown by way of example in the drawings and will be described in detail herein. It should be understood, however, that there is no intention to limit the disclosure to the particular forms disclosed, but on the contrary, the intention is to cover all modifications, equivalents and alternatives falling within the spirit and scope of the invention as defined by the appended claims. form.

[0031] Such as Figure 1-4 As shown in FIG. 2 , the tibial spacer 10 includes a platform 12 defining an upper bearing surface 14 , and a keel 16 attached to a lower surface 18 of the platform 12 and extending downwardly from the platform 12 . As an example, the tibial spacer 10 is a unicompartmental tibial spacer intended to replace only one of the two condyles 20 of the tibia 22, as shown in Figure 5shown in . In other words, the tibial s...

Abstract

A tibial insert includes a platform defining an upper bearing surface and a bottom surface. A keel of the tibial insert is coupled to the bottom surface of the platform. A surgical method for knee anthroplasty is also disclosed.

Description

technical field [0001] The present disclosure relates generally to orthopedic surgical prostheses, and more particularly to tibial inserts and methods of using such tibial inserts. Background technique [0002] During the patient's life, it may be necessary to perform joint replacement surgery on the patient due to reasons such as disease or trauma. For example, many knee replacement surgeries are performed each year. A total knee replacement or arthroplasty may include replacement of the midshaft portion of the femur, the proximal, distal, and / or entire portion of the femur, and the proximal tibia. Unicompartmental knee arthroplasty or arthroplasty involves repair of a single articular surface. Unicompartmental knee arthroplasty offers an alternative to reconstructing the knee joint when only one condyle has been damaged due to trauma or disease, for example due to non-inflammatory degenerative joint disease or osteoarthritis or traumatic arthritis complex Another option...
