Secondary patella resurfacing is a controversial procedure which is applied in patients with anterior knee pain
after a bicondylar knee arthroplasty (with unresurfaced patella). A group of 46 patients were submitted to this procedure
and their satisfaction, range of motion and pain improvement was evaluated. 52.2% of the patients were satisfied with the
procedure, with an improvement in pain (Visual Analogue Scale) of 65% and an improvement in range of motion in
56,5%, with roundabout half of the patients having no resolution to their complaints. Whilst an improvement was not
achieved in all patients, as it was initially hypothesised, this procedure should be considered when a revision knee
arthroplasty is performed with an unresurfaced patella.
