Cyclic Testing of 3 All-Inside Meniscal Repair Devices

Abstract

The Meniscal Cinch and Ultra FAST-FIX devices may be more desirable implants for use during all-inside meniscal repair as they have superior biomechanical properties when compared with the MaxFire device.

Analysis of a New All-Inside Versus Inside-Out Technique for Repairing Radial Meniscal Tears

“…5,8,9 These loads were chosen based on the methods of numerous other studies that evaluated the biomechanical strength of meniscal repairs, because these loads are thought to approximate in vivo loads the meniscus faces. [10][11][12] Furthermore, these loads are in keeping with previous studies on meniscal repair by our group and others. 5,13-15 Data were recorded continuously (WaveMatrix; Instron, Norwood, MA).…”

Shear Force at Failure and Stiffness of All-Inside Meniscal Repair Devices

“…[8] Recently, several second and third generation devices have been developed and tested biomechanically. [3][4][5][6][7][15][16][17][18] Farng et al performed a clinical and biomechanical review of several all-inside device studies. They found a large variation in study methodology especially in loading rate.…”

“…Several studies have examined the biomechanical strength of repair techniques for meniscal lesions focusing on the strength, stiffness and displacement of the repair in tension. [3][4][5][6][7][8] However, meniscal injuries often occur secondary to a rotational force while under axial loading. The resultant oblique vector is defined as a shear force.…”

All-Inside Meniscal Repair Devices Compared With Their Matched Inside-Out Vertical Mattress Suture Repair

“…29,37,38 Biomechanically, inside-out suture repairs are the gold standard for meniscal repairs, although this method bears an increased risk for injury to neurovascular structures and is associated with increased perioperative morbidity. 9,26 To decrease these complications, the first all-inside meniscal repair was performed in 1991 by Morgan,27 and the approach has been further improved since then. The first generation of all-inside repair devices (resorbable, rigid arrow) provided rigid fixation and good clinical outcomes, but they were associated with high failure rates and damage to the articular cartilage.…”
