Arthroscopic Matrix-Based Meniscus Repair Surgical Technique With “Goat” Instrument

Abstract

Human meniscal treatment with an arthroscopic matrix-based meniscal repair technique is a promising procedure. Heretofore, the procedure has required a skilled surgeon with a great amount of experience in knee arthroscopic surgery and meniscal suturing. A surgical technique using a “goat” delivery clamp has been developed. Technique development followed extensive review and the application of earlier arthroscopic matrix-based meniscal repair techniques, along with cadaveric refinement of the proposed arthroscopic technique. The presented technique includes preparation of the meniscus with initial stabilization of the damaged fragments, preparation of the collagen matrix and placement of this matrix into the open jaws of the goat delivery clamp, introduction of the collagen matrix into the knee and placement of this matrix on the meniscus, suturing of the collagen matrix to the meniscus, and bone marrow blood aspirate injection between the collagen matrix and meniscus.
