Anterolateral Segmental Meniscal Allograft Transplantation.

Background: The medial and lateral menisci increase joint congruity, stabilization, shock absorption, and proprioception. Deficient menisci provide challenges for orthopaedic surgeons and often require meniscal transplantation. Current techniques for meniscal transplant may sacrifice native healthy meniscus that could be preserved. Indications: We present a novel technique for anterolateral segmental meniscal transplant, which serves to replace the deficient anterolateral meniscus with the preservation of the intact posterior midbody and horn. Technique Description: Using meniscal root, all-inside, and outside-in meniscal repair techniques, we present a successful segmental anterolateral meniscal transplant. Results: While only limited short-term outcomes are available due to the novel nature of this procedure, our patient is following the same protocol as a total meniscal transplant without any complications. Discussion/Conclusion: While long-term and larger cohorts are needed, segmental meniscal transplant is a potential novel technique to address non-total meniscal deficiency without sacrificing healthy meniscal tissue.
