However, the number and optimal placement of CSs remain unclear.<\/jats:p>\n <\/jats:sec>\n \n Hypothesis:<\/jats:title>\n Increasing numbers and changing localization of CSs would not influence the degree of postoperative extrusion or joint contact pressures.<\/jats:p>\n <\/jats:sec>\n \n Study Design:<\/jats:title>\n Controlled laboratory study.<\/jats:p>\n <\/jats:sec>\n \n Methods:<\/jats:title>\n Meniscal extrusion and tibiofemoral contact pressures were assessed using a 3-dimensional motion capture system and pressure sensors in 9 human cadaveric knees. A nonanatomic root repair was created to simulate persistent meniscal extrusion after a PMMR repair. Each knee was tested under 10 conditions: (1) intact, (2) PMMR tear, (3) root repair, (4) CS at the posterior border of the medial collateral ligament (MCL) (CS1), (5) CS midway between CS 1 and CS 3 (CS2), (6) CS at the midpoint between the MCL and posterior root attachment (CS3), and (7-10) combinations of these CSs (all CSs were in addition to the root repair). Analysis of variance testing was used for analyses of pressure data and extrusion measurements.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n \n There was no significant difference in medial contact pressure between the intact state and the states with root repair in combination with any CS configuration (\n P<\/jats:italic>\n > .05). Contact pressures were reduced compared to the root repair state for CS1 alone at 0\u00b0 (\n P<\/jats:italic>\n = .014); the combination of CS2 and CS3 at 0\u00b0, 60\u00b0, and 120\u00b0 (\n P<\/jats:italic>\n \u2264 .038); and the combination of all 3 CSs at 0\u00b0, 30\u00b0, and 60\u00b0 of flexion (\n P<\/jats:italic>\n \u2264 .037). Extrusion was reduced compared to the root repair state for CS1 alone at 60\u00b0 (\n P<\/jats:italic>\n = .043) and all 3 CSs combined at 90\u00b0 of flexion (\n P<\/jats:italic>\n < .009).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion:<\/jats:title>\n A single CS placed at the posterior border of the MCL decreased medial contact pressures at 0\u00b0 and reduced extrusion at 60\u00b0 of flexion. The combined use of 2 CSs placed at the posteromedial meniscus junction reduced contact pressures across multiple flexion angles (0\u00b0, 60\u00b0, and 120\u00b0). The combination of 3 CSs reduced contact pressures at 0\u00b0, 30\u00b0, and 60\u00b0 and extrusion at 90\u00b0. Until clinical studies are conducted, the benefits of additional CSs should be weighed against time and cost.<\/jats:p>\n <\/jats:sec>\n \n Clinical Relevance:<\/jats:title>\n These findings should guide surgeons on the optimal number and placement of CSs to minimize meniscal extrusion and restore medial compartment contact pressures.<\/jats:p>\n
