Abstract
Seven different autologous chondrocyte implantation (ACI) grafts were used consecutively over a period of 18 years for the treatment of cartilage lesions in the knees. The aim was to evaluate this entire ACI patient series for graft-related or unrelated serious adverse events (SAE), graft failures, and to reveal potential risk factors for these incidents. The study group comprised 151 operated patients: classical periosteum-ACI (n = 45); ACI-seeded fibrin-collagen patch, fixed by either periosteum (n = 59), collagen membrane (n = 15), or fibrin glue (n = 6); ACI seeded alginate-agarose hydrogel (n = 14); and biomimetic collagen-hydroxyapatite scaffold injected with the ACI suspension (n = 12). The covariates analyzed as possible predicting factors were: age, gender, BMI, lesion depth, lesion size, lesion location, previous surgeries, and concomitant procedures. The Kaplan-Meier method for estimating survival curves, and Cox's proportional hazards model to test for covariates, were used in the statistical analysis. The patients in this series, follow-up 10.1 (2.1-18.3) years, encountered 11% of graft-related SAE (risk factors: previous cartilage surgery, age over 40 years, BMI over 25 kg/m2, and meniscus s...
