Arthrex provee aloinjertos de meniscos congelados procesados en forma ascéptica necesarios para los transplantes de meniscos. Los aloinjertos de meniscos de Arthrex vienen preparados con un bloque óseo precortado que permite la flexibilidad del cirujano para determinar la técnica de transplante preferida. El aloinjerto se combina específicamente con cada paciente en base a las radiografías prequirúrgicas o a las imágenes de resonancia magnética. 
 
Los instrumentos Arthrex para transplante de menisco Dovetail o laparoscópicos ofrecen opciones de técnicas reproducibles simples, y seguras.

Procedure

The segmental meniscus transplant technique addresses failed repair of the meniscus while avoiding total replacement. Patients who have irreparable defects can benefit from a partial replacement, completed using the segmental meniscus transplant technique, which provides the same tibiofemoral joint compartment biomechanics as an intact meniscus.1-3 This technique helps preserve the native biomechanical loading principles of the knee while keeping intact native hoop fibers.

Segmental Meniscus Allograft Transplantation

Patrick A. Smith, MD (Columbia, MO), performs a segmental meniscal allograft transplantation procedure. The entire technique and several pearls are included, including defect preparation and measurement as well as graft preparation and fixation. Stable fixation is achieved using the ZoneNavigator™ device to complete inside-out suture delivery and the FiberStitch™ implant for side-to-side fixation.

Segmental Meniscus Transplantation Surgical Technique

J. Lee Pace, MD (Plano, TX), discusses the scientific support for segmental meniscus replacement to treat irreparable meniscal deficiencies. Dr. Pace also reviews biomechanics and surgical considerations when treating these deficiencies.

Segmental Meniscus Transplantation for Irreparable Meniscal Deficiencies

Matthew T. Provencher, MD (Vail, CO), presents a case of focal meniscus deficiency treated with a segmental meniscus allograft transplantation. Dr. Provencher also shares several technical pearls and concomitant procedure considerations for this case, in addition to his rehabilitation protocol.

Segmental Meniscus Allograft Transplantation for a Focal Meniscal Deficiency

Segmental Meniscus Transplant

Soft-tissue meniscal allograft transplantation techniques continue to evolve with the advancement of fixation devices. Using common meniscal repair devices allows for greater flexibility while ensuring anatomic graft placement. Soft–tissue-only meniscal allograft surgical techniques and clinical outcomes are well documented and have good clinical efficacy.1-4
