NexGen MIS LPS-Flex Mobile Implant System
Surgical Technique
Step Twelve: Prepare the Patella
Knee flexed 90°.
Turn the patella approximately 90°.
To facilitate exposure, apply two towel clips to the
nonarticular proximal and distal aspects of the patella,
and apply gentle thumb pressure on the dorsal side of
the patella.
Sharply dissect through the prepatellar bursa to
expose the anterior surface of the patella. This will
provide exposure for affixing the anterior surface into
the patellar clamp.
Remove all osteophytes and synovial insertions from
around the patella. Be careful not to damage tendon
insertions on the bone. Use the patellar caliper to
measure the thickness of the patella (Figure 12a).
Subtract the implant thickness from the patella
thickness to determine the amount of bone that should
remain after resection.
