Features and Benefits

Using patient imaging, each meniscal allograft is matched to the unique patient via Pollard Method for medial menisci or the Yoon (Modified Pollard) for lateral menisci.
Use different techniques of meniscus allograft transplantation using only soft tissue, a segmental meniscus, bone blocks, or a bone bridge
Prepared with precut bone block which allows surgeons to select appropriate implant technique
Sized matched per patient
Restores natural knee kinematics
Frozen to preserve the anatomical integrity of the fibrocartilage

Long-term Outcomes and Survivorship of Fresh-Frozen Meniscal Allograft Transplant With Soft Tissue Fixation: Minimum 10-Year Follow-up Study

Meniscal allograft transplant (MAT) is considered an effective procedure for reducing pain and improving knee function.

Meniscus Allograft Transplantation: Indications, Techniques and Outcomes

There are three main fixation methods that can be used to fix a MAT: suture-only fixation, double plug fixation and the keyhole technique. All fixation methods have similar outcomes, meaning that despite the biomechanical differences, the selection of which method to use should be made on a case-by-case basis.

Segmental Meniscus Allograft Transplantation

Segmental meniscus allograft transplantations may offer the advantage of a robust repair by both maintaining knee biomechanics and biology while maximizing preservation of native meniscal tissue.

Higher Survivorship Following Meniscal Allograft Transplantation in Less Worn Knees Justifies Earlier Referral for Symptomatic Patients

Meniscal transplantation is clinically effective in treating patients with symptomatic meniscal deficiency.

Long-Term Survival Analysis and Outcomes of Meniscal Allograft Transplantation with Minimum 10-Year Follow-Up

MAT can yield good long-term survivorship rates of allografts remaining functional after 10 and 15 years.

Meniscal Allograft Transplantation in the Paediatric Population

MAT can improve function and reduce pain in the paediatric population, and is, therefore, a viable treatment option for the management of the symptomatic paediatric meniscal-deficient knee.

Open Meniscal Allograft Transplantation w/Transosseous Suture Fixation of Meniscal Body Decreases Meniscal Extrusion Rate

This study identified similar absolute extrusion and significantly lower postoperative lateral meniscal extrusion rates after open MAT compared with arthroscopic MAT.

Return to Sport Activity After Meniscal Allograft Transplantation: At What Level and at What Cost?

Physical activity after MAT appears possible, especially for low-impact sports.

Clinical Outcomes of Meniscal Allograft Transplantation With or Without Other Procedures

Overall, there seems to be no significant difference between the postoperative patient reported outcomes in terms of isolated MAT and combined MAT.

Midterm and Long-term Results of Medial Versus Lateral Meniscal Allograft Transplantation: A Meta-analysis

Patients undergoing lateral meniscal allograft transplantation demonstrated greater pain relief and functional improvement than patients undergoing medial meniscal allograft transplantations.

Meniscal Allograft Transplantation: Indications, Techniques, Outcomes

Meniscal allograft transplantation (MAT) has become an acceptable surgical treatment for select symptomatic and relatively young patients with a meniscal deficiency.

Surgical Techniques

Meniscal Allograft Transplantation Featuring Dovetail Allograft

The dovetail technique simplifies graft preparation by shaping the bone block into a semi-trapezoidal “dovetail” structure that securely seats in a matching bone slot on the tibia, followed by peripheral FiberWire fixation to restore meniscal anatomy and stability in lateral compartment reconstruction.

Double Bone Plug Meniscus Reconstruction

Using two bone plugs drilled into the posterior and anterior horn areas, this method secures the meniscal allograft with precise plug sizing, retro-drilled sockets, and sutures over the capsule to achieve stable fixation at biologically critical horn attachments.

Trough (Bone-Bridge) Meniscus Technique Guide

The trough (or bone-bridge) technique creates a continuous tibial trough across both meniscal horn attachment zones and seats a complementary bone bridge from the allograft, delivering rigid fixation and maintenance of hoop-stress mechanics while restoring native meniscal curvature.

All-Soft-Tissue Meniscus Allograft Transplantation

This technique avoids bony fixation altogether, using circumferential soft-tissue sutures and suture-tape augmentation to centralize the allograft, mitigate hoop stress, and facilitate conformal placement while preserving graft biology.

Segmental Meniscus Allograft Transplantation

A focused grafting approach that restores localized meniscal defects using size-matched segmental allograft tissue trimmed to fit the defect and secured with inside-out and all-inside suturing devices to maintain kinematics and preserve native meniscus.

Meniscus Technique Guide

This comprehensive guide presents an illustrated overview of various MAT techniques—soft-tissue, segmental, bone-plug, and bone-bridge—highlighting procedural decision-making, pros/cons of each fixation method, and surgeon guidance to match technique with patient anatomy.
