Objectives- The purpose of the study was to observe whether PRP, Mesenchymal Stem Cells (MSCs) and combining them could help make improvements the healing of Achilles tendons in rabbits. Design- Experimental study. Animals-Sixteen male, healthy and mature white New Zealand rabbits. Procedures- The animals were...

BACKGROUND Bicipital tendinitis is a common cause of anterior shoulder pain, but there is no evidence that acute inflammation of the extra-articular long head of the biceps (LHB) tendon is the root cause of this condition. We evaluated the histologic findings of the extra-articular portion of the LHB tendon and synovial sheath in order to compare those findings to known histologic changes seen ...

It is not known how extensively a localised flexor tendon injury affects the entire tendon. This study examined the extent of and relationship between histopathologic and gene expression changes in equine superficial digital flexor tendon after a surgical injury. One forelimb tendon was hemi-transected in six horses, and in three other horses, one tendon underwent a sham operation. After euthan...

PURPOSE Our purpose was to determine whether a bioresorbable interference screw coated with a hydroxyapatite-based mineral layer designed to release an engineered peptide growth factor (linkBMP-2 [where "BMP-2" indicates bone morphogenetic protein 2]) improved tendon-bone healing compared with a screw without coating. METHODS Tagged linkBMP-2 peptides were used to quantify binding efficiency ...

Nineteen consecutive patients undergoing anterior cruciate ligament reconstruction using the central third of the ipsilateral patellar tendon were included in the study. Serial magnetic resonance images revealed that the donor-site gap in the tendon decreased with time (mean follow-up, 26 months). The thickness was significantly increased compared with the intact contralateral patellar tendon, ...

BACKGROUND Tendon and synovial sheath disease is common. A method of monitoring the status of tendons and sheaths is important for both diagnosis of pathology and evaluation of the efficacy of treatments. For this study, an ultrasound scoring tool was developed and its reliability tested between raters. The tool is novel in that it scores tendons and sheaths separately, an important considerati...

PURPOSE Tibialis anterior tendon transfers (TATT) are commonly performed in young children following Ponseti casting for clubfeet. The classic TATT involves advancing the tendon through a hole drilled in the ossified cuneiform. The aim of this study was to determine if tendons transferred through unossified bones have untoward effects on subsequent bone development. METHOD Twenty-five piglets...

BACKGROUND The etiologic role of corticosteroid therapy in tendon rupture is controversial. This study compared the effects of injected versus iontophoretically delivered corticosteroid on the normal rabbit Achilles tendon. METHODS Rabbits were divided into three treatment groups: (1) corticosteroid injections, (2) iontophoretically delivered corticosteroid, and (3) no treatment. One tendon o...

OBJECTIVES Compare histologic and biomechanical differences of tendon-to-bone healing between autologous and allogeneic bone transplants. MATERIALS AND METHODS Adult, healthy, New Zealand white rabbits were used to establish the extra-articular tendon-to-bone healing model with the left hind limb transplanted with allogeneic bone and the right hind limb transplanted with autologous bone. Afte...

Newly emergent turkey arthritis reoviruses (TARVs) have been isolated from cases of lameness in male turkeys over 10 weeks of age. In a previous study, experimental inoculation of TARV in one-week-old turkey poults produced lymphocytic tenosynovitis at four weeks post inoculation but without causing clinical lameness. This study was undertaken to determine if TARV infection at an early age can ...
