title: [Effect of abrasion on three types of sutures in a metallic anchor].
abstract: It is necessary to slide the suture into the articulation in the arthroscopic techniques, this produce friction and abrasion of the suture, this is the principal cause of failure in the union of anchor-suture. We used a Fastak 2.4 anchor, Sawbones, No 2 Ethibond, No 2 Fiberwire and No 2 Herculine. Each suture was introduce to the anchor eyelet and was cycled in four times with 40N. The angles of traction were 0 degrees and 45 degrees at the same direction of the anchor eyelet and 45 degrees with different direction of the anchor eyelet. Five sutures were used in every test. We performed the Kolmogorov-Smirnof and "t" Student tests. In all the tests there were a significant differences. The strength of the suture is affected by the abrasion in the anchor eyelet.
