PURPOSE: To identify factors associated with functional recovery and outcome 1
year after total knee arthroplasty (TKA). METHODS: In the prospective follow-up
study, all the patients (n = 75, aged 60-80 years) underwent primary TKA.
Assessments were performed preoperatively and 12 months after surgery. The main
measures were the Western Ontario and McMaster Universities OA Index (WOMAC) and
the 15D. The clinical examination included analyses of comorbidity and a detailed
knee examination. Age-standardised population values of the 15D and the Outcome
Measures in Rheumatology-Osteoarthritis Research Society International
(OMERACT-OARSI) criteria were used as indices of response. RESULTS: Osteoporosis,
pain, gender, age and preoperative function of the opposite knee accounted for
29.9% of the variance in the change in the WOMAC function score. A preoperative
score of the 15D below the age-standardised population level, pain, higher age
and pulmonary disease reduced the possibility to reach the HRQOL level of the
general population. Osteoporosis decreased the likelihood of achieving responder
status according to the OMERACT-OARSI criteria. CONCLUSION: The baseline
preoperative score of the 15D strongly associated with the achieved level of
HRQOL after TKA. The findings of the present study highlight the multifactorial
nature of health status in TKA.
