Abstract

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

颗粒状幼年同种异体软骨植入的远期效果:11年二次关节镜1例并文献复习
高级别的骨软骨损伤会引起疼痛、功能受限,通常需要手术治疗。描述的手术干预措施包括微骨折、自体骨软骨移植物移植、同种异体骨软骨移植、自体软骨细胞植入和基质辅助自体软骨细胞移植。顽固性软骨缺损的另一种选择是颗粒化幼年同种异体软骨(PJAC)植入。对PJAC的短期研究在其透明质或透明质样软骨再生能力方面取得了有希望的结果,尽管该手术的长期结果尚不清楚。我们介绍了一例对一名15岁女子竞技足球运动员股骨内侧髁实施PJAC的病例,该患者进行了11年的磁共振成像和关节镜下复视随访。此外,我们进行了文献综述,总结了先前发表的PJAC结果数据。
