Background As utilization rates for total joint arthroplasty increase, there is
a hesitancy to perform this surgery on very old patients. The objective of
this prospective study was to compare pain, functional, and health-related
quality-of-life outcomes after total hip and total knee arthroplasty in an
older patient group ( 80 years) and a representative younger patient group
(55-79 years).
Methods In an inception community-based cohort within a Canadian health care
system, 454 patients who received primary total hip arthroplasty (n = 197)
or total knee arthroplasty (n = 257) were evaluated within a month prior to
surgery and 6 months postoperatively. Pain, function, and health-related quality
of life were evaluated with the Western Ontario and McMaster Universities
(WOMAC) Osteoarthritis Index and the 36-Item Short-Form Health Survey (SF-36).
Results There were no age-related differences in joint pain, function, or quality-of-life
measures preoperatively or 6 months postoperatively. Furthermore, after adjusting
for potential confounding effects, age was not a significant determinant of
pain or function. Although those in the older and younger groups had comparable
numbers of comorbid conditions and complications, those in the older group
were more likely to be transferred to a rehabilitation facility than younger
patients. Regardless of age, patients did not achieve comparable overall physical
health when matched with the general population for age and sex.
Conclusions With increasing life expectancy and elective surgery improving quality
of life, age alone is not a factor that affects the outcome of joint arthroplasty
and should not be a limiting factor when considering who should receive this
surgery.
