Pain, an uncommon complication following a total knee arthroplasty, ha
s been associated with infections, loosening, reflex sympathetic dystr
ophy, and occasionally litigation. Radiographic abnormalities such as
the anatomic alignment, size of the prosthesis, and tilt of the prosth
esis after surgery have been implicated as other sources of pain. It i
s shown that there is no correlation between the above abnormalities a
nd pain.
