NexGen Mobile Bearing
|
The NexGen LPS and LPS Flex Mobile knee is designed for patients with high-flexion and demanding lifestyle/habits. A mobile bearing option can be combined with any Legacy Knee Femoral Component to match your patient’s individual needs. A single, posterior stabilised, mobile articulating surface that matches the LPS, LPS-Flex and LCCK Femoral Components gives patients the chance to achieve their maximum range of motion. The tibial plate allows internal/external axial rotation of 500, with an anterior stop that helps prevent the spin-outs reported with other mobile systems. |

Providing extensor mechanism clearance
The articular surface features a deeper anterior patellar cut-out to reduce extensor mechanism tension and provide greater clearance for the patellar tendon during deep flexion.
Accommodating deep flexion
Extended posterior condyles on the femoral component accommodate greater tibio-femoral contact during deep flexion to 155 degrees. Proper sizing of the LPS-Flex Femoral Component to it’s matching mobile bearing surface helps assure conformity in both A/P and M/L planes.
Providing stability
A modified PS cam/spine mechanism is designed to provide the stability for range of motion up to 155 degrees. The LPS-Flex cam/spine design increases subluxation resistance at deep flexion angles. Proportionally sized anchoring pegs on the femoral component provide additional stability and enhanced fit.
NexGen LPS Mobile bearing knee
A deepened patellar groove relieves pressure on the patella, thereby reducing forces that can lead to premature wear. For greater stability, the patellar groove is extended to maximise patello-femoral contact.
The femoral components feature symmetric medial and lateral femoral radii that are matched to size-specific articular surfaces. These components are designed to reduce wear by increasing contact area and distributing stress more evenly.
Optimally proportioned bearing spaces accommodate a large contact areaon the loaded condyle and resist edge loading even in up to 7 degrees of varus/volgus tilt.
