Knees, of course
Demand for total knee
procedures is skyrock-
eting across the coun-
try and serves as the
foundation of any out-
patient joint program.
At Andrews ASC,
orthopedic surgeon
Charlie Roth, MD,
replaces the knees of
patients with BMIs
between 35 and 40 who are free of comorbidities. The
total knee system he uses features computerized
alignment, thanks to MRI-based cutting blocks, which
Dr. Roth says limit blood loss by eliminating the need
to drill into the intra-medullary canal on the tibia or
the femur. Computerized alignment of the limb also
lets Dr. Roth predict the actual size of the implant
before implanting it.
Dr. Roth approaches the joint through an anterior
longitudinal incision. He laterally resects the patella
and extensor mechanism in the knee before cutting
blocks are placed on the tibia and femur to shape
the ends of both bones. He removes the ACL and
possibly the PCL and all meniscus remnants, makes
the cuts needed to match the femur and tibia
implant components and places trial spacers
between the components on the femur and tibia.
Once the spacers are placed, he tests the joint's
