New possibilities for analyse.
Purpose:
 Analyse the answers from the patients
that returned the 1 and 5-year follow-up
by WOOS score from 2004 to 2009.
 Analys the results by diagnoses
concerning the different concepts of
arthroplasty (Hemi or Total).
2011
 > 8100 primary reports since 1999
 > 637 (8 %) were re-operations.
 About 1000 reports yearly
 covers >90%
