- W2613402255 abstract "Background Structural and functional outcome of bone graft with first or second generation autologous chondrocyte implantation (ACI) in osteochondral defects has not been reported. Methods Seventeen patients (mean age of 27±7 years, range 17–40), twelve with osteochondritis dissecans (OD) (ICRS Grade 3 and 4) and five with isolated osteochondral defect (OCD) (ICRS Grade 4) were treated with a combined implantation of a unicortical autologous bone graft with ACI (the Osplug technique). Functional outcome was assessed with Lysholm scores. The repair site was evaluated with the Oswestry Arthroscopy Score (OAS), MOCART score and ICRS II histology score. Formation of subchondral lamina and lateral integration of the bone grafts were evaluated from MRI scans. Results The mean defect size was 4.5±2.6SD cm 2 (range 1–9) and depth was 11.3±5SD mm (range 5–18). The pre-operative Lysholm score improved from 45 (IQR 24, range 16–79) to 77 (IQR 28, range 41–100) at 1 year (p-value 0.001) and 70 (IQR 35, range 33–91) at 5 years (p-value 0.009). The mean OAS of the repair site was 6.2 (range 0–9) at a mean of 1.3 years. The mean MOCART score was 61 ± 22SD (range 20–85) at 2.6 ± 1.8SD years. Histology demonstrated generally good integration of the repair cartilage with the underlying bone. Poor lateral integration of the bone graft on the MRI scan and a low OAS were significantly associated with a poor Lysholm score and failure. Conclusion Osplug technique shows significant improvement of functional outcome for up to 5 years in patients with a high grade OD or OCD. This is the first report describing association of bone graft integration with functional outcome after such a procedure. It also demonstrates histological evidence of integration of the repair cartilage with the underlying bone graft. Level of Evidence III" @default.
