Increasing experience with unicompartmental knee
arthroplasty is turning it into a more viable option
for treating isolated lateral or patellofemoral
arthritis - but more work is needed to determine
exactly what the inclusion and exclusion criteria
should be, according to an orthopedic surgeon from
Ohio.
Keith R. Berend, MD, discussed his findings with an
audience at the Current Concepts in Joint
Replacement 2010 Winter Meeting in Orlando, Fla.
Movement toward unicompartmental knee arthroplasty (UKA)
seems to be "a natural progression" given its
conservative and less invasive nature when compared
to total knee arthroplasty, Berend said, noting that
early experience with a mobile bearing medial UKA
shows excellent function and 98% survivorship
throughout 6 years.
"Partial knee arthroplasty is by definition the only
minimally invasive technique for the treatment of
isolated, single compartment osteoarthritis of the
knee," Berend told Orthopedics Today. "Additionally,
in the case of medial partial knee, significant
amounts of patellar disease seen on preoperative
radiographs can safely be ignored as these findings
do not seem to affect survivorship."
...Though more work is needed to gain proper
experience and learn more of the indications for UKA, Berend said
there are numerous reasons for pursuing it as an alternative to more
invasive options.
"Partial knee arthroplasty, whether it be medial, lateral, or
patellofemoral, is truly the only minimally invasive approach that
we can offer patients, and I would urge you to take this
compartmentalist approach," he concluded. "I think it makes treating
the arthritic knee effective, but it also makes sense and it would
certainly make things easier."
