Abstract Background Superior biomechanical performance of tapered interference screws, compared with non-tapered reference to the anterior cruciate ligament (ACL) reconstruction process, has been reported in literature. However, effect screw’s body slope on initial stability ACL is poorly understood. Thus, main goal this study was investigate reconstructed ACL. Methods Based best screw-bone tun...

Surgical treatment for injuries to soft connective tissues are estimated at about 800,000 cases each year in the US. For these surgical procedures, interference screws or suture anchors are needed. Currently, materials used for the devices are non-degradable metals or bioresorbable polymers. However, these materials do lead to complications. Metallic materials suffer from difficulties encounter...

background: fracture load of implant-supported restorations is an important factor in clinical success. this study evaluated the effect of two techniques for screw access hole preparation on the fracture load of cement-screw retained implant-supported zirconia-based crowns. methods: thirty similar cement-screw retained implant-supported zirconia-based maxillary central incisor crowns were evalu...

OBJECTIVE the aim of this study was to radiologically evaluate the femoral tunnel position in anterior cruciate ligament (ACL) reconstructions using the isometric and anatomical techniques. METHODS a prospective analytical study was conducted on patients undergoing ACL reconstruction by means of the isometric and anatomical techniques, using grafts from the knee flexor tendons or patellar ten...

PURPOSE To evaluate the insertion torque of a soft-tissue interference screw in relation to depth of insertion into the tibial tunnel when used for fixation of a quadrupled semitendinosus-gracilis autograft in anterior cruciate ligament reconstruction. TYPE OF STUDY Biomechanical cadaver study. METHODS Ten quadrupled semitendinosus-gracilis grafts were harvested from fresh-frozen cadaver kn...

We report the case of a patient with a painful subcutaneous nodule, measuring 13 mm × 17 mm, at the pretibial graft aperture site, which presented two years after a successful anterior cruciate ligament reconstruction with an autologous hamstring graft. A bioabsorbable poly-L-lactide interference screw was used for graft fixation at the tibial aperture. The patient underwent surgical excision o...
