BACKGROUND There are still controversies about graft selection for primary anterior cruciate ligament reconstruction, especially with respect to knee stability and functional outcome. HYPOTHESIS Biodegradable interference screw fixation of hamstring tendon grafts provides clinical results similar to those achieved with identical fixation of bone-patellar tendon-bone grafts. STUDY DESIGN Coh...

The purpose of this study was to describe the anatomy and characterize the biomechanics of the posterolateral aspect of the canine knee. Ten adult canine knees were each used for anatomy and biomechanical testing. Distances and motion limits were measured using a 6 degree-of-freedom electromagnetic tracking system. Canine knee dissection reproducibly identified structures present in the human p...

ANATOMY The TFCC is a fibrocartilage-ligament complex which stabilizes the distal radioulnar joint (DRUJ), transmits axial load between the carpus and the ulna, and stabilizes the ulnar aspect of the carpus. The TFCC is comprised of the disc proper (articular disc), meniscus homologue, ulnolunate ligament, ulnotriquetral ligament, proximal ligamentous component, volar and dorsal radioulnar liga...

A study has been made of the ultrastructural organization of the collagen fibrils and elastic fibres in tendons and ligaments from horses of ages ranging from 2 months premature to 19 years. Diameter distributions of the collagen fibrils in the common digital extensor tendon, the super­ ficial flexor tendon and the suspensory ligament are unimodal in the foetal tissue and a t birth, and a t the...

Tendons transmit forces from muscle to bone and provide the joint function and ligaments transmit forces from bone to bone and provide joint stability. Tendon and ligament injuries have high incidence and management of tendon and ligament injuries is technically demanding because the healing response of these soft connective tissues is low. In addition, number of the available options to be con...

Simultaneous rupture of both the patellar tendon and the anterior cruciate ligament is a relatively rare injury. Its diagnosis can easily be missed during the initial examination. Treatment options include immediate repair of the patellar tendon with either simultaneous or delayed reconstruction of the ACL. We present the case of a combined rupture of the patellar tendon, the anterior cruciate ...

In the rare cases with serious damage of the Medial Collateral Ligament (MCL) of the knee requiring surgical treatment, ligament remnants may be inadequate for a good repair. In such cases, reconstruction should be performed and technical options may be limited. We used an Achilles tendon allograft and applied it using the Pulvertaft weave technique for tendon repair. We found no previous repor...

Ligament reconstruction with the LARS ligament has been a popular choice owing to its low-complication rates compared with previously commercially available grafts. The non-active nature of the implant also meant that there were no foreign body reactions that had been described with other synthetic grafts. We describe the first reported case of a granulomatous foreign body reaction in a LARS li...

Anterior cruciate ligament (ACL) injury is a relatively common knee injury during sports activities (Uhorchak, 2003). A torn ACL usually occurs through a twisting force being applied to the knee whilst the foot is firmly planted on the ground or upon landing (Boden, 2000). The traditional surgical treatment for ACL rupture is ACL reconstruction by an autogenous tendon graft. However, fibroblast...

A method to study ligament-length patterns in situ with roentgen-stereophotogrammetry, using strings of glued tantalum markers, was developed. The method was tested against a bone-to-bone marking method in five carpal ligaments in three specimens, whereby the hand was moved through dorsopalmar flexion and radioulnar deviation. The "glued-string" marking method was found to be superior to the bo...
