BACKGROUND Two main factors determine the strength of tendon repair; the tensile strength of material and the gripping capacity of a suture configuration. Different repair techniques and suture materials were developed to increase the strength of repairs but none of techniques and suture materials seem to provide enough tensile strength with safety margins for early active mobilization. In orde...

Minimally invasive techniques to repair ruptured achilles tendons have been developed to enhance recovery following tendon repair and decrease wound complications associated with open repair. We investigated outcomes of minimally invasive and open repair of acutely ruptured achilles tendons at our institution. We compared all cases of achilles tendon repair at our department, using open techniq...

BACKGROUND Degenerative rotator cuff tears are a significant cause of shoulder pain in the aging population. Rotator cuff repair surgery may be more successful when growth factors are delivered to the repair site. This study was designed to determine the cellular processes involved in normal bone-to-tendon healing and the current approaches used for biologic augmentation of rotator cuff repair....

Rupture of tendons due to either high load or laceration is a common injury, especially for the hand. Tendon disorders are traditionally treated by reducing inflammation, restoring flexibility, and, if necessary, performing surgical repair. It has been estimated that hand surgeons repair nearly one-third of a million digital flexor tendon injuries per year in the United States. Despite the fact...

BACKGROUND Tendon adhesion is one of the most common causes of disability following tendon surgery. Therefore, prevention of peritendinous adhesion after surgical repair of tendon is a major challenge. The aim of this study was to explore the possible application of a collagen membrane for the prevention or attenuation of peritendinous adhesions. METHODS Sprague-Dawley (SD) rat Achilles tendo...

Background Following injury to the rotator cuff and anterior cruciate ligament, a direct enthesis is not regenerated, and healing occurs with biomechanically inferior fibrous tissue. Demineralized bone matrix (DBM) is a collagen scaffold that contains growth factors and is a promising biological material for tendon and ligament repair because it can regenerate a direct fibrocartilaginous insert...

Objective- The aim of this study was to investigate the PRP effects on the early time-period during tendon healing in rabbits DDF tendon. Design-Experimental study Animals- Twenty male New Zealand white rabbits Procedure-PRP samples were prepared using twice centrifugation method of modification of the Cuarsan...

Spontaneous flexor tendon ruptures are rare. Thirteen patients who had spontaneous intratendinous rupture of the flexor digitorum profundus tendon are described. Twelve of the ruptures occurred in zone III at the level of the lumbrical origin, and one occurred in zone II distal to the A2 pulley. All patients were involved in an activity that required flexion against resistance. Time from injury...

Flexor tendon injury has long been recognised as a difficult problem to tackle in hand surgery. Loss of active motion in the digits results in significant morbidity. The increased understanding in tendon healing, role of the tendon sheath, and the development of mobilisation and repair techniques have drastically improved results of flexor tendon injuries over the last 50 years. The treatment o...

BACKGROUND Chronic noninsertional Achilles tendinosis can result in an acute Achilles tendon rupture with a short distal stump. In such tendon ruptures, there is a limited amount of adequate tissue that can hold suture, thus presenting a challenge for surgeons who elect to treat the rupture operatively. HYPOTHESIS Adding suture anchors to the repair construct may result in biomechanically str...
