Ethgen et al.16 |
Age |
Age was not a factor in pain outcomes. Results were mixed for physical function: either no effect or older age associated with somewhat worse scores. Reported change in pain and function were similar across age groups, but status was generally worse with older age.
|
Sex |
Results were mixed: either no difference in change in pain and function, or men trended toward greater improvement in function and/or pain. Status at follow-up trended toward better among men.

Obesity |
Results were inconsistent for health-related quality-of-life outcomes. Generally, no influence was identified; some patients reported worse postoperative pain and functional status.

Mental well-being |
|
Comorbidity |
A greater number of comorbid conditions were associated with worse short- term pain and functional outcomes. The overall impact appeared to be relatively small. The influence of older age was believed to be mediated through number of conditions.

Santaguida et al.18 |
Age |
Results were inconsistent for revision surgery; younger patients were at somewhat greater risk at 2–20 yr. Older age was associated with greatest risk of death at 30–90 d. Older age was associated with poorer function, though not when assessed using WOMAC. Age was not associated with postoperative satisfaction, but older age was associated with less satisfaction after revision surgery.
|
Sex |
Results were inconsistent for revision surgery; men were at somewhat greater risk, particularly younger men. Men were generally at greater risk of death at 30–90 d. Women generally had poorer function, showed less functional improvement and showed less postoperative pain. Sex was not associated with satisfaction following the primary procedure, but women reported less satisfaction following revision surgery.
