Long-term results of particulated juvenile allograft cartilage implantation: a case report with eleven-year second-look arthroscopy and review of literature

High-grade osteochondral lesions cause pain, functional limitations, and oftentimes require surgical treatment. Described operative interventions include microfracture, autograft transfers, allograft transplantation, autologous chondrocyte implantation, matrix assisted implantation. Another option for recalcitrant cartilaginous defects is particulated juvenile cartilage (PJAC) Short-term studies into PJAC have yielded promising results in its capacity hyaline or hyaline-like regeneration though the long-term outcomes of this procedure are not well understood. We present a case implementation to medial femoral condyle 15-year-old female competitive soccer player with 11-year magnetic resonance imaging arthroscopic second-look follow-up. In addition, we performed literature review summarize prior published data.
