Fig 5.

Radial meniscus tears can be repaired with the Ceterix device by placing circumferential stitches in any combination that best reduces and compresses the tear. (A) The central third of the meniscus can be excised, and the central and peripheral thirds can be repaired with side-to-side or figure-of-8 sutures. The photographs show a radial tear of the posterior horn of the medial meniscus (B) in a 55-year-old man with completely healthy tricompartmental articular surfaces. (C) Photograph taken after passage of the first stitch, showing the device being removed with the suture after it has been self retained in the upper jaw. (D) In this case the central 2 sutures were used to shuttle polydioxanone, and a third stitch was placed more peripherally and left as No. 2-0 nonabsorbable suture to back up the repair. Polydioxanone is sometimes used in radial tear repairs because the more central knots cannot be peripheralized like they can with circumferential compression stitches that are placed in the central to peripheral vector. Video 1 includes excerpts from this repair.
