There are several techniques to treat chondral defects. Osteochondral allograft transplantation is an excellent option, and for elongated lesions, there are 2 techniques-the Snowman technique and the BioUni technique.
Osteochondral allograft transplantation is indicated for active individuals with isolated, symptomatic full-thickness chondral defects without concomitant ligamentous injury or malalignment.
The lesion on the native condyle is sized. A plug is then harvested from the allograft using a cutting block and sagittal saw. The recipient site is then prepared with an overlapping reamer system with a cutting block. Graft is then implanted in a press-fit manner.
Osteochondral allograft transplantation leads to improved patient-reported outcomes. The literature has demonstrated survival rates between 70% and 80% at 10 years.
DISCUSSION/CONCLUSION: Osteochondral allograft transplantation is a restorative cartilage treatment that has good clinical outcomes. The BioUni system is a good option for irregular or elongated lesions.
治疗软骨缺损有多种技术。骨软骨异体移植是一种很好的选择，对于细长型病变，有两种技术——雪人技术和BioUni技术。
骨软骨异体移植适用于有孤立性、有症状的全层软骨缺损且无合并韧带损伤或排列不齐的活跃个体。
测量天然髁上的病变大小。然后使用切割块和矢状锯从异体移植物中获取一个栓子。接着使用带有切割块的重叠扩孔钻系统准备受区。然后将移植物压配植入。
骨软骨异体移植可改善患者报告的结局。文献表明，10年时的生存率在70%至80%之间。
讨论/结论：骨软骨异体移植是一种具有良好临床效果的软骨修复治疗方法。BioUni系统对于不规则或细长型病变是一个很好的选择。
