Abstract
Objective This retrospective analysis aimed to evaluate patient and defect characteristics on return to work after autologous chondrocyte implantation (ACI) for all patients with workers compensation insurance in our clinic. Methods Retrospective analysis of medical records of patients with workers compensation treated with ACI in our clinic over 10 years (August 2004 to November 2014). Data were collected on demographics, lesion size and location, number of defects, duration of symptoms, and outcomes. Results A total of 28 patients with 30 ACI procedures were included in this analysis. Patients had a mean age of 40.0 years, were mostly male, and tended to be overweight (mean body mass index = 31.5 kg/m2). Most patients were employed in occupations with high physical demand (85.7%) compared with lower physical demand jobs (14.3%). The mean number of lesions per knee = 1.73. Overall, the mean total surface area of the defect was large (12.6 cm2), with large mean individual lesion size of 7.39 cm2. All 28 patients returned to work in some capacity, with a total of 22 (79%) returning to full work, and 6 (21%) returning to modified work. There were no significant differences in the comparison of patients who returned to full versus modified work, in mean age, body mass index, high versus low physical demand occupation, or lesion characteristics (size, chronicity, or location). Conclusions Our results demonstrate that in a challenging workers compensation cohort, in patients with multiple large defects, treatment with ACI allows a high percentage of patients to return to their normal vigorous work activities within 9 months to 1 year following cartilage restoration. This study is a level IV retrospective case series.
