Segmental Meniscus Transplant
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.
Dovetail/Slot Meniscal Transplant Technique
The dovetail technique simplifies graft preparation with a time-saving series of cuts preparing the bone component of the graft to sit securely in the recipient semi-trapezoidal slot created in the tibia. A matching semi-trapezoidal shaped recipient slot created in the tibia with a series of step drills, rasps and dilators matches the bone block preparation.Subsequent peripheral graft fixation to the capsular rim with 2-0 FiberWire® achieves the goal of creating a solid meniscal allograft construct. Preferably performed for lateral meniscal incompetence, the dovetail technique anatomically recreates the normal lateral meniscal relationships within the knee.
Double Bone Plug Meniscal Transplant
The Double Bone Plug technique for meniscal tear/deficiency utilizes bone plugs that can either be prepared freehand or by using a coring reamer. The freehand technique is performed using rongeurs and a high speed burr. For detailed information about this technique and/or Arthrex products utilized in this technique, visit the educational resources tab or products tab below.The double bone plug technique for meniscal allograft reconstruction provides a method for implanting the meniscal allograft medially with rigid fixation at both horn attachments. It has been demonstrated that bony fixation and bony healing at the attachment site allows for the maintenance of functional hoop stress by the meniscal allograft.
Soft Tissue Meniscal Allograft Transplantation Technique
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
