steoarthritis (OA) is
the largest source
of physical disability
in the United
States,
30
and the
joint most commonly affected by
OA is the knee.

Total knee
arthroplasty (TKA) is frequently
implemented as a treatment for
knee OA when more conservative
options have been attempted and
have failed to relieve disabling
symptoms.

The incidence of TKA
has been steadily rising and is
predicted to result in a rate of
nearly half a million surgeries per-formed annually in the United
States by the year 2030.

Despite a
rise in utilization of TKA, very
little is known regarding the influ-ence of residual impairment on
functional limitations in people
with knee OA after TKA
