Background:
Bilateral simultaneous total hip arthroplasty (BSTHA) and
bilateral simultaneous total knee arthroplasty (BSTKA) are controversial
procedures, since some studies report a higher incidence of medical and
surgical complications after these procedures compared with unilateral or
staged bilateral total hip- and knee arthroplasty (BTHA, BTKA).
Purpose / Aim of Study:
To investigate length of stay (LOS), readmissions
and mortality after bilateral total hip- and knee arthroplasty in Denmark and to
compare outcome after simultaneous and staged procedures.
Materials and Methods:
All patients who underwent bilateral total knee- or
hip arthroplasty in Denmark in a period from 01.07.2009 to 31.06.2011 were
found using data from the national health registry. We distinguished between
simultaneous bilateral and staged bilateral procedures. The staged bilateral
procedure was defined as bilateral THA/TKA done in 2 stages within 6
months. Data were analyzed using SPSS 20 and are presented as mean (SD) or
Median (IQR) where appropriate. Length of stay (LOS) for the staged
processes (BTKA and BTHA) was added to provide a total LOS.
Findings / Results:
BSTKA (n=158): Mean age was 64.0 (0.65) years, 53%
females, median LOS was 4(3) days and 90 days mortality was 0%. BTKA
(
n=640): Mean age was 66.7 (0.37) years, 57% females, median LOS was 6(3)
days and 90 days mortality was 0.94%. BSTHA (n=104): Mean age was 55.8
(1.37)
years, 43% females, median LOS was 4(3) and 90 days mortality was
0%.
BTHA (n=597): Mean age was 66.6 (0.44) years, 60% females, median
LOS was 6(3) and 90 days mortality was 0.33%.
Conclusions:
Preliminary results show that LOS is significantly higher after
bilateral staged hip and knee arthroplasty compared with simultaneous bilateral
procedures. Data regarding outcome will be included in the final analysis.
