Secondary patella resurfacing in painful non-resurfaced total knee arthroplasties A study of survival and clinical outcome from the Norwegian Arthroplasty Register (1994-2011)

摘要

In Norway, 19 % of revisions of non-resurfaced total knee arthroplasties done for knee pain between 1994 and 2011 were Secondary Patella Resurfacing (SPR). It is, however, unclear whether SPR actually resolves the pain. The aim was to investigate prostheses survival and clinical outcomes following SPR.
