Patellar tendon ruptures are rare but very invalidating lesions. We describe a case of re-rupture of a sutured patellar tendon. An autologous semitendinosus graft was used for tendon augmentation in the reconstruction procedure. This technique uses an easy-to-harvest graft which has low donor site morbidity. Additionally, the strength of the graft allows early rehabilitation, and no further sur...

BACKGROUND We previously developed a novel technique using an alternate soaking process that improves tendon-bone healing by hybridizing the tendon graft with calcium phosphate (CaP). However, the effects of the CaP-hybridized tendon graft on anatomic single-bundle anterior cruciate ligament (ACL) reconstruction remain unclear. PURPOSE To determine the effects of CaP-hybridized tendon grafts ...

OBJECTIVE To analyse the bone-ligament integration «ligamentization» of the tendon graft in the reconstruction of anterior cruciate ligament (ACL) performing tunnels of different diameter. MATERIAL AND METHODS We performed the same reconstruction procedure using an autologous tendon graft taken from the superficial tendon of the hoof in 41 adult sheep. In Group A the tibial and femoral tunnel...

BACKGROUND/AIMS This study investigated the effect of mechanical stress on tendon-bone healing in a rabbit anterior cruciate ligament (ACL) reconstruction model as well as cell proliferation and matrix formation in co-culture of bone-marrow mesenchymal stem cells (BMSCs) and tendon cells (TCs). METHODS The effect of continuous passive motion (CPM) therapy on tendon-bone healing in a rabbit AC...

INTRODUCTION The distal triceps tendon rupture is an uncommon injury. The acute treatment is well-defined, but when a delayed diagnosis is made or when a tendon retraction is present the alternatives or reconstruction are limited and sometimes complex. CASE PRESENTATION In this case, we report on a 28-year-old man who presented with a chronic disruption of the distal triceps tendon with a gap...

BACKGROUND Complete rupture of the distal biceps tendon from its osseous attachment is most often treated with operative intervention. Knowledge of the overall tendon morphology as well as the orientation of the collagenous fibers throughout the musculotendinous junction are key to intraoperative decision making and surgical technique in both the acute and chronic setting. Unfortunately, there ...

BACKGROUND The palmaris longus tendon is frequently used as a tendon graft or ligament replacement. In rare instances the median nerve has been inadvertently harvested instead of the palmaris longus for use as a tendon. METHODS Nineteen cases in which the median nerve had been mistakenly harvested instead of the palmaris longus tendon were collected from members of the American Society for Su...

PURPOSE To evaluate the mid-term outcome of anterior cruciate ligament (ACL) reconstruction using the medial third of the patellar tendon as the bone-patellar tendon-bone (BPTB) graft. METHODS 79 men (34 right knees and 45 left knees) aged 20 to 52 (mean, 28) years underwent ACL reconstruction using the medial third of the patellar tendon with bone plugs and were followed up for a minimum of ...

INTRODUCTION Acute concomitant rupture of both anterior cruciate ligament (ACL) and patellar tendon is a rare injury. The diagnosis of either of the injuries may be missed on clinical examination in the emergency room. A high index of suspicion is necessary when active extension is absent, and necessary investigations like ultrasound or magnetic resonance imaging (MRI) should be done to confirm...
