OBJECTIVE To determine whether the human Achilles tendon has higher material properties than other tendons and to test for strain rate sensitivity of the tendon. DESIGN Mechanical testing of excised tendons. BACKGROUND While the human Achilles tendon appears to experience higher in vivo stresses than other tendons, it is not known how the Achilles tendon's material properties compare with t...

BACKGROUND The purpose of this meta-analysis of randomized controlled trials (RCTs) and non-RCTs was to compare the clinical outcomes of autograft versus allograft tendons in patients who underwent posterior cruciate ligament (PCL) reconstruction. METHODS We conducted a search of PubMed, EMBASE, The Cochrane Library, and Web of Science databases for RCTs and non-RCTs comparing autograft and a...

Metabolic diseases such as diabetes mellitus type-II (DM-II) may increase the risk of suffering painful connective tissue disorders and tendon ruptures. The pathomechanisms, however, by which diabetes adversely affects connective tissue matrix metabolism and regeneration, still need better definition. Our aim was to study the effect of DM-II on expressional changes of neuro- and angiotrophic me...

BACKGROUND Laceration of the hand extensor tendons is common in the upper extremities, causing soft tissue trauma. These tendons, because of their superficial location and lying adjacent to bones, have a greater tendency to be injured than flexor tendons. OBJECTIVES The aim of this study was to determine the results of primary repairs of lacerated extensor tendons of the fingers, with respect...

BACKGROUND To date, no studies document the effect of anabolic steroids on rotator cuff tendons. STUDY DESIGN Controlled laboratory study. HYPOTHESIS Anabolic steroids enhance remodeling and improve the biomechanical properties of bioartificially engineered human supraspinatus tendons. METHODS Bioartificial tendons were treated with either nandrolone decanoate (nonload, steroid, n = 18), ...

Vertebrate limb tendons are derived from connective cells of the lateral plate mesoderm. Some of the developmental steps leading to the formation of vertebrate limb tendons have been previously identified; however, the molecular mechanisms responsible for tendinous patterning and maintenance during embryogenesis are largely unknown. The eyes absent (eya) gene of Drosophila encodes a novel nucle...

BACKGROUND Palpation is an important clinical test for jumper's knee. OBJECTIVES To (a) test the reproducibility of palpation tenderness, (b) evaluate the sensitivity and specificity of palpation in subjects with clinical symptoms of jumper's knee, and (c) determine whether tenderness to palpation may serve as a useful screening test for patellar tendinopathy. The yardstick for diagnosis of p...

Tissue engineering of an anterior cruciate ligament (ACL) implant with ACL cells requires detailed analysis of the tissue characteristics that should be mimicked. Therefore, we studied the histological and biochemical properties of rabbit derived ACLs in comparison to other knee-associated tendons that are used as autografts in men. Rabbit derived ACLs and Musculus (M.) semimembranosus, M. semi...

In this paper, a prestressed precast reinforced concrete (PC) beam–column connection incorporating posttensioned debonded partial tendons is introduced for PC frame structure. Compared with the conventional cast-in-place frames and many previously proposed connections frames, has advantage of self-centering low damage in strong earthquakes. addition, can reduce posttensioning demand further sit...

A calf with congenital bilateral  exural deformity of the metacarpo-phalangeal joints was presented and subsequently diagnosed as contraction of super cial digital  exor tendons. It was treated with tenotomy of super cial digital  exor tendons.
