A narrative review of lateral meniscus transplantation with the bridge in slot: technique and outcomes.

Objective: This narrative review aims to detail the indications, technique, and published outcomes of the bridge in slot technique for lateral meniscus allograft transplantation (LMAT) and to serve as a concise reference for orthopaedists looking to incorporate this method into their practice.

Background: The menisci are crucial to normal knee function but are commonly injured; partial and subtotal meniscectomy are frequently performed to address meniscal pathology. Following these procedures, a substantial number of patients go on to develop degenerative joint changes accompanied by pain and disability. LMAT is an attractive option for young, active, lateral meniscal-deficient patients who seek pain relief and improved function but who are not yet prepared to undergo arthroplasty. In the properly indicated patient, the bridge in slot technique is a reliable and effective method for LMAT.

Methods: Using a narrative style, this review outlines the indications and preoperative assessment for LMAT, the detailed technical steps for the bridge in slot technique, postoperative considerations, and trends in the surgical outcomes literature. The presented technique is consistent with the senior author's clinical experience and with published literature and the discussed outcomes are elicited from a focused review of recent peer-reviewed sources.

Conclusions: The bridge in slot technique is a reliable and effective method for LMAT and is supported by the literature. This technique may confidently be used in patients with severe lateral meniscal pathology who are not yet candidates for arthroplasty.
