Combined Medial Meniscus Allograft Transplantation and Open-Wedge High Tibial Osteotomy Using a Patient-Specific Instrumentation Guide.

Abstract

Despite technical advances in meniscus allograft transplantation, there remains a need to improve postoperative outcomes.¹ ^, ² The bone plugs technique using osseous fixation of the anterior and posterior roots has demonstrated increased stability and long-term survival. Recently, the importance of limb alignment has been demonstrated for this procedure. In case of malalignment, osteotomy is essential to improve the long-term viability of both meniscus allograft and cartilage. The recent introduction of patient-specific instrumentation has raised the possibility of making instrumentation specific to each patient achieving an optimal correction in a safe and reliable manner. This Technical Note describes the use of a combined medial meniscus allograft transplantation and open wedge high tibial osteotomy using a patient-specific instrumentation guide.
