Background:
Hip and knee arthroplasty are common surgical procedures with
respectively 9.500 and 8.500 operations performed annually in Denmark.
These operations are considered effective and successful in relation to compli-
cations, mortality and prosthesis survival. However using patient reported out-
come measures up to 20 % of the patients are not satisfied with their outcome
of the operation. To be able to act on this, it is important to find out why some
patients experience impaired outcome after operation.
Purpose / Aim of Study:
The purpose of the study was to investigate the im-
pact of age on health related quality of life (HRQoL) after total hip athroplasty
(THA), total knee athroplasty (TKA) and unicompartmental knee arthroplasty
(UKA).
Materials and Methods:
A cohort study was conducted with follow-up at
3-4 and 12 months. Data were collected from September 2008 to December
2013. 1283 THA, 736 TKA and 257 UKA were available for analysis. HRQoL
was measured using the EQ-5D. Analysis were carried out with multiple linear
regression and adjusted for relevant variables available in data.
Findings / Results:
A significant positive association was found between age
and HRQoL outcome for patients operated with THA at both 3-4 and 12 months
of follow-up. A clinically relevant change was achieved with an increase of age
at approximately ten years. Estimates for TKA and UKA were not found statisti-
cally significant regarding the association between age and HRQoL. However no
statistically significant difference was found between estimates for THA, TKA
and UKA.
Conclusions:
Increasing age was associated with increasing HRQoL outcome
for patient operated with THA. This association was not found for TKA and UKA.
Contrary to expectations increasing age did not seem to have a negative impact
on HRQoL outcome for any of the three types of operations.
