Abstract: INTRODUCTION: While there is extensive literature supporting a high success rate, there is limited data on return to work following total knee arthroplasty (TKA).
METHODS: A multicenter study was conducted of patients of working age (18-60) who underwent TKA one to three years previously. An independent third party survey center with expertise in collecting health care data for state and federal agencies collected the data. Definitions from the United States Department of Labor’s Dictionary of Occupational Titles were utilized to determine physical job demand categories of sedentary, light, medium, heavy and very heavy.
RESULTS: Complete data was collected on 661 TKA patients (average age 54.2, 61.3% female). A total of 74.6% (493/661) were employed in the three months prior to their TKA and 91.1% (449/493) returned to work after surgery, 93.3% of which successfully returned to the same job. Prior to surgery, the labor categories of the patients jobs were sedentary 13.2%, light 10.8%, medium 23.9%, heavy 23.3% and very heavy 28.8%. The return to work rate by labor category was sedentary 92.3%, light 79.2%, medium 89.0%, heavy 87.8% and very heavy 78.2%. Males were significantly more likely to return to work than females (82.3% vs. 73.7%, p=0.015).
DISCUSSION AND CONCLUSION: In this group of young, active patients, most returned to work at their usual occupation. While those with sedentary occupations had the highest return to work rate, even those with very heavy jobs returned to work almost 80% of the time.
