BACKGROUND Functional restoration is the major concern after flexor tendon reconstruction in the hand. The purpose of the present study was to investigate the effects of modifying the surface of extrasynovial tendon autografts with carbodiimide-derivatized synovial fluid with gelatin (cd-SF-G) on functional outcomes of flexor tendon reconstruction using a canine model. METHODS The second and ...

This article presents a case of a large inferior patellar osteophyte, which developed after patellar tendon autograft anterior cruciate ligament (ACL) reconstruction. This extensive osteophyte formed a neo-articulation with the tibial plateau and contributed to arthrofibrosis, patellar baja, and patellar pain. This is an extremely unusual complication following patellar tendon harvesting for AC...

PURPOSE To report outcomes of revision anterior cruciate ligament (ACL) reconstruction using tibial or hamstring tendon allografts and to compare with another study using non-irradiated fresh-frozen bone-patellar tendon-bone allografts. METHODS Records of 12 men and 7 women aged 18 to 53 (mean, 33) years who underwent revision ACL reconstructions using tibial tendon (n=17) or hamstring tendon...

Autologous bone-patellar tendon-bone autograft is a common choice for anterior cruciate ligament reconstruction and from both biologic and biomechanical perspectives is well-suited for this purpose. A centrally harvested, 10 mm wide patellar tendon graft has an estimated initial load-to-failure of 2977 N, and interference screw fixation of associated bone blocks provides initial pull-out streng...

The question of which graft to use for anterior cruciate ligament (ACL) reconstruction continues to be debated at meetings around the world. The overall choice of grafts consists of autografts, allografts, and synthetic grafts. By far the two most commonly used grafts are central third bone-patellar tendon-bone and hamstring tendon, either semitendinosus alone or semitendinosus combined with gr...

The Achilles tendon is the most common ruptured tendon of human body. Reconstruction with polyethylene terephthalate (PET) artificial ligament is recommended in some serious cases. Sodium hyaluronate (HA) is beneficial for the healing of tendon injuries. We aimed to determine the effect of sodium hyaluronate in repair of Achilles tendon defect with PET artificial ligament in an animal tendon re...

BACKGROUND Patellar and hamstring tendon autografts are the most frequently used graft types for anterior cruciate ligament reconstruction, but few direct comparisons of outcomes have been published. HYPOTHESIS There is no difference in outcome between the two types of reconstruction. STUDY DESIGN Prospective randomized clinical trial. METHODS After isolated anterior cruciate ligament rup...

Hamstring tendon autograft is a routine graft for anterior cruciate ligament (ACL) reconstruction. However, ways of improving the healing between the tendon and bone is often overlooked in clinical practice. This issue can be addressed by using a biomimetic scaffold. Herein, a biomimetic nanofiber membrane of polycaprolactone/nanohydroxyapatite/collagen (PCL/nHAp/Col) is fabricated that mimics ...

Introduction: Posterior tibial tendon reconstruction frequently involves transfer of the flexor digitorum longus (FDL) tendon to the navicular and debridement of the diseased portion of the posterior tibial tendon as well as a calcaneal osteotomy and possibly a lateral column lengthening. If the posterior tibial tendon muscle appears to have some contractile property then it is anastamosed to t...

Basic science and clinical investigation have advanced significantly the treatment and the outcome following intrasynovial flexor tendon repair and rehabilitation and reconstruction over the past 30 years. The application of modern multistrand suture repair techniques as well as postoperative rehabilitation protocols emphasizing the application of intrasynovial repair site excursion has led to ...
