dc.description.abstractObjectives: This study aims to investigate the effectiveness of arthroscopic autologous matrix-induced chondrogenesis (AMIC) procedure with or without polyglycolic acid-hyaluronic acid ( PGA-HA)-based cell-free scaffold (CFS) in Bristol E4 and E5 osteochondral lesion of the talus (OLT) ranging between 1.5 and 3 cm(2). Patients and methods: Between March 2018 and March 2021, a total of 47 patients with OLTs (29 males, 18 females; mean age: 22.8 +/- 2.3 years; range, 18 to 65 years) were retrospectively analyzed. The patients were divided into two groups based on the procedures applied. Patients in the first group (Group 1, n= 23) underwent the AMIC procedure alone (curettage, microfracture, and grafting), while patients in the second group (Group 2, n=24) underwent AMIC procedure with PGA-HA-based CFS. The localization of the lesions was evaluated. All OLTs were diagnosed with preoperative radiography and magnetic resonance imaging ( MRI). During the preoperative period, lesion stages were evaluated based on the Bristol staging system, and the postoperative results were evaluated based on the Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) scoring system. Results: The mean follow- up was 36.2 +/- 5.6 months. In the early period, the three-month functional scores were comparable between the groups. While a significant increase was observed in the American Orthopaedic Foot and Ankle Society (AOFAS) scores from the mean preoperative of 62.71 +/- 4.44 points to the postoperative of 86.00 +/- 6.58 points in Group 1, a significant increase in the AOFAS score was observed from 65.28 +/- 7.91 points to 95.42 +/- 4.41 points in Group 2 at 12-month follow-up (p= 0.016, p=0.011, respectively). The functional scores tended to progress after 12 months. Radiologically, a complete defect filling was observed in a mean of 10.5 +/- 2.7 months. No graft hypertrophy was recorded in any patients. The AOFAS and MOCART scores in Group 2 were found to be statistically significantly higher than that in Group 1 (p= 0.034 for AOFAS 1/AOFAS 2 and p=0.006 for MOCART 1/MOCART 2). Overall, there was a positive, but weak, significant correlation between the final AOFAS scores and MOCART scores (r= 0.347, p<0.001). Conclusion: Arthroscopic AMIC procedure in deep OLTs between 1.5 cm(2) and 3 cm(2) can yield a statistically significant improvement both clinically and radiologically; however, the use of a PGA-HA-based CFS in addition to this procedure can improve the clinical and radiological recovery.en_US
