Abstract

Background

Total Knee Arthroplasty (TKA) is a highly successful treatment for advanced osteoarthritis (OA) of the knee. More than two-thirds of the TKA patients return to work (RTW) within three months postoperatively. However, being back at work does not necessarily imply successful functioning at work. If signs of reduced work ability and work functioning are detected in an early stage, actions can be initiated to prevent work absence. Aim of the present study is to provide information about the level of work ability and work functioning among TKA patients who returned to work after surgery. Moreover, to examine the association of demographic-, disease-, and work-related variables with work ability and work functioning.

Methods

A cross-sectional survey study was conducted in sixty-two patients who underwent a TKA between 2006 and 2010 in three hospitals in the northern region of the Netherlands. Work ability was measured with the overall single-item of the Work Ability Index (WAI). Work functioning was measured with the total score of the Work Role Functioning Questionnaire (WRFQ 2.0). Multiple logistic regression analyses were conducted to examine the association of demographic, disease- and work-related variables with both outcome measures.

Results

Twenty-six (41.9%) participants scored low (≤7) work ability, twenty-four (38.7%) participants scored low (≤90) on work functioning. Logistic regression showed that higher education ((OR 4.00; 95%CI: 0.93-17.11) was significantly associated with better work ability. Younger age (OR 0.72, 95%CI: 0.56-0.93), higher education level (OR 1.79, 95%CI: 0.24-13.60) and no comorbidity (OR 0.02, 95%CI: 0.00-1.16) were significantly associated with better work functioning. Living situation, body mass index and work type were not associated with both outcome measures.

Conclusions

This study showed that 40% of those who returned to work after TKA scored low on work ability and work functioning. Furthermore it was found that younger, high-educated preoperative patients have better change to remain healthy at work returning after TKA surgery. Further prospective studies are needed to confirm these findings.
