NexGen MIS LPS-Flex Mobile Implant System
Surgical Technique
Step Ten: Perform Trial Reduction
In this step, a trial reduction is performed to check
component position, patellar tracking, ROM, and joint
stability.
Check the LPS/LPS-Flex mobile compatibility chart
for component matching instructions.
Insertion of Femoral Provisional Using
Optional MIS Femoral Inserter/Extractor
Determine the type of NexGen implant or provisional
being used – in this case the Posterior Stabilized (PS).
Refer to the side of the instrument, labeled PS or CR
(see (A) & (B)) which corresponds with the implant or
provisional type (Figure 10a).
Initially adjust the femoral rotation setting and tension
setting. For the femoral rotation setting, a good
starting point is between the lines of the implant type
(A). For the tension setting, start with the two lines
aligned (B).
Open the locking handle (G) to attach the implant
or provisional. Attach the implant or provisional by
positioning the instrument hook (Figure 10b).
