About this product

Division: Mitek Sports Medicine
Category: ACL Reconstruction

The RIGIDFIX ® ACL Cross Pin System is an innovative method for fixing soft tissue or bone-tendon-bone grafts during ACL reconstruction. The pins are available in two sizes; 3.3mm for soft tissue grafts and 2.7mm for BTB grafts.  The unique, patented RIGIDFIX Cross Pin System was developed to:

  1. provide strong, rigid fixation with the use of two absorbable cross pins (PLA and Biocryl)
  2. offer 360° of graft-to-bone contact with added compression from the cross pins to promote bony ingrowth
  3. provide close to aperture fixation to minimize graft micromotion in the tunnel
  4. ease-of-use to expedite surgery

Intended Use

Femoral and tibial fixation of autograft or allograft ACL soft tissue (semitendinosus and gracilis) and bone-tendon-bone grafts.

Features & Benefits

 

Features Benefits
Strong, rigid fixation  Rigidfix 3.3mm cross pins for soft tissue grafts demonstrated 642N of pull-out strength and 1.4mm of elongation after cyclic loading.  The 2.7mm BTB cross pins had 424N of pull-out strength providing a secure, strong reconstruction.1
Close to aperture fixation  Minimizes intratunnel graft micromotion and the “bungee” effect.
360 degrees of graft to bone contact No device interference between graft and bone and pins provide additional compression of graft to promote biologic in-growth.
Ease-of-Use  The system is intuitive and the simple technique helps to expedite surgery time and is easily reproducible. 
 Bioabsorbable material. ß-TCP/PLLA composite. RIGIDFIX crosspins are available in a ß-TCP/PLLA composite –Mitek’s proprietary BIOCRYL material. BIOCRYL is molded using a proprietary process called Microparticle Dispersion to ensure a uniform mixture of ß-TCP and PLLA throughout the implant. ß-TCP is a well known osteoconductive bioceramic often used in bone-void filling applications.  Previously published imaging studies using ß-TCP/polymeric ACL fixation devices have demonstrated various levels of ossification, and in some cases complete ossification at the implant site.2
