Bone defects caused by femoral and tibial tunnel enlargement can pose a significant technical challenge when planning to perform revision anterior cruciate ligament reconstruction. A number of options have been described for managing osseous deficiencies, including the use of large autograft or allograft bone dowels to provide sufficient tunnel fill and subsequent structural support for revision surgery. These techniques can be time-consuming and technically demanding to ensure proper tunnel fill and press-fit stability of the bone graft. We describe our preferred technique for arthroscopic bone grafting using a mixture of demineralized cortical bone graft augmented with platelet-rich plasma delivered through a simple delivery system.
在计划进行前交叉韧带翻修重建时，股骨和胫骨隧道扩大所导致的骨缺损会带来重大的技术挑战。对于处理骨缺损，已有多种方法被描述，包括使用大型自体骨或同种异体骨栓，以提供足够的隧道填充并为翻修手术提供后续的结构支撑。这些技术可能耗时且对技术要求高，以确保骨移植的隧道填充恰当和压配稳定性。我们描述了我们首选的关节镜下骨移植技术，即使用通过简单输送系统输送的富含血小板血浆增强的脱矿皮质骨移植混合物。
