Medial Meniscus Allograft Transplant: Arthroscopic Soft Tissue Technique With Suture Tape Augmentation

Meniscal allograft transplant (MAT) is gaining popularity for treating meniscus deficiency. Various MAT techniques are described. Bony techniques such as bone plugs and bone slot techniques are considerably more technically challenging but show better reduction of extrusion than all-soft-tissue technique. This MAT technique describes an arthroscopic all-soft-tissue fixation, using suture tape augmentation. It combines the technically simpler all-soft-tissue MAT method with suture tape augmentation to mitigate hoop stress and act as an 'internal brace', thereby adding additional resistance to extrusion. By relying on circumferential suture tape augmentation rather than a centralization stitch to reduce extrusion, this technique more closely replicates the biomechanics of the native meniscus.
