Cruciate-retaining knee prosthesis

摘要

H:/gw/Interwoven/NRPortbl/DCC/GW/1072225 1_doc-8/12/2016 Certain versions generally provide an improved tibial base member (for example, but not limited to, 10) comprising keel portions (for example, but not limited to, 14a, 14b, 14c) that allow one or both cruciate ligaments to be preserved. Other versions provide improved lateral and/or medial inserts (for example, but not limited to, 110, 210) having a mesial lip (for example, but not limited to, 118, 128) that helps relieve and/or prevent impingement between the femoral component (for example, but not limited to, 400) and the tibial eminence. Other versions provide improved femoral components (for example, but not limited to, 400) having various chamfers (for example, but not limited to, 404, 410, 470) to provide additional clearance with respect to the tibial eminence and posterior cruciate ligament without decreasing bone coverage. 116 18a 16a" 114c' 14c 12a 18b 14a" 19c 16b 15c 15a1 15b 19a K 19b FIG. 1 15c 15c 16a 12a 14a 10 14a ''3 4 16a' I-x14b' 14b 14c''14 14c' 15c 12c 12b 16b 16b'
