| description | Category: Ankle; Basic Sciences/Biologics Introduction/Purpose: The purpose of this systematic review was to evaluate the clinical and radiological outcomes together with the complication rates and failure rates at short-term follow-up following Particulated Juvenile Allograft Cartilage (PJAC) for the management of osteochondral lesions of the talus (OLT). Methods: During November 2022, the PubMed, Embase and Cochrane library databases were systematically reviewed to identify clinical studies examining outcomes following PJAC for the management of OLTs. Data regarding study characteristics, patient demographics, lesion characteristics, subjective clinical outcomes, radiological outcomes, complications and failure rates were extracted and analysed. In addition, the level of evidence and quality of evidence for each individual study was also assessed. Results: Twelve studies were included. In total, 241 patients underwent PJAC for the treatment of OLT at a weighted mean follow-up of 29.0±24.9 months. The weighted mean lesion size was 138.3±59.6 mm 2 and 69.4% of OLTs were located at the medial talar dome. Prior surgical intervention was recorded in 7 studies, the most common of which was microfracture (65.9%). Concentrated bone marrow aspirate was utilized in 66 patients (27.3%). The weighted mean AOFAS score improved from a pre- operative score of 58.5±3.2 to a post-operative score of 83.9±5.3. The weighted mean post-operative MOCART score was 48.2±3.3. The complication rate was 16.5%, the most common of which was graft hypertrophy (7.0%). Thirty failures (12.4%) were observed at a weighted mean time of 9.8±9.6 months following the index procedure. Conclusion: This systematic review demonstrated a moderate improvement in subjective clinical outcomes following PJAC for the treatment of OLT at short term follow-up. However, post-operative MOCART scores were reported as poor. In addition, a moderate complication rate (16.5%) and a moderate failure rate (12.4%) was observed, calling into question the efficacy of PJAC for the treatment of large OLTs. Further studies are warranted to identify the optimal role of PJAC in the management of OLTs. |
