Objectives- Hydroxyproline is a specific amino acid of collagen which is widely used to estimate the collagen content in biological specimens. The purpose of this study was to compare the effect of the Platelet Rich Plasma (PRP) on tendon gap healing using two different scaffold made from subcutaneous fascia and polypropylene tube. Design- Experimental study Animals - 16 young adult Guinea pigs...

BACKGROUND The patellar tendon has limited ability to heal after harvesting its central third. Platelet-rich plasma (PRP) could improve patellar tendon healing. HYPOTHESIS Adding PRP to the patellar tendon harvest site would improve donor site healing and improve clinical outcome at 6 months after anterior cruciate ligament (ACL) reconstruction with a patellar tendon graft. STUDY DESIGN Ran...

Achilles tendon tear is common and increasingly frequent. Magnetic resonance imaging (MRI) is the modality of choice for radiological evaluation. It is accurate to assess the status and integrity of the tendon with well documented features. In this article, the MR findings of a normal Achilles tendon as well as common diseases like insertional and noninsertional tendinosis, chronic tendinosis w...

The primary goal of this study was to evaluate a cross-linked acellular porcine dermal patch (APD), as well as platelet-rich plasma fibrin matrix (PRPFM), for repair of acute Achilles tendon rupture in a sheep model. The 2 surgically transected tendon ends were reapproximated in groups 1 and 2, whereas a gap was left between the tendon ends in group 3. APD was used to reinforce the repair in gr...

background tendon injuries are common and it takes a long time for an injured tendon to heal. adverse phenomena such as adhesion and rupture are associated with these injuries. finding a method to reduce the time required for healing whichimproves the final outcome, will lead to decreased frequency and intensity of adverse consequences. this study was designed to investigate the effects of basi...

BACKGROUND Ponseti management usually requires Achilles tenotomy during the final stage of serial casting. However, we lack a good understanding of the sequential tendon healing process after tenotomy in the Ponseti bracing protocol. The purpose of this study was to clarify the ultrasonographic process of tendon healing in the gap for up to two years after Ponseti-type Achilles tenotomy in pati...

BACKGROUND Clinical studies have demonstrated a high rate of incomplete healing of rotator cuff tendon repair. Since healing of such a repair is dependent on bone ingrowth into the repaired tendon, we hypothesized that osteoinductive growth factors would improve rotator cuff tendon-healing. METHODS Seventy-two skeletally mature sheep underwent detachment of the infraspinatus tendon followed b...

Platelet Rich Fibrin (PRF) is a new biological augmentation material which is remarkable with its rich cellular components and growth factors. The aim of this study was to evaluate the effect of PRF on tendon healing in a rat model. PRF and control groups included eight rats. PRF was obtained with centrifuging blood collected from the rats and applied on the tendon repair site in Achilles tendo...

Objectives- Tendons are integral parts of musculoskeletal system and are subjected to injury. Fibroblast is used in tendon healing, however, there is no proved and reported result regarding concurrent use of allogenic fibroblast with static magnetic field in tendon healing. In addition, there are some studies done on the effect of magnetic fields on tendon healing but the results are antithesis...

Background: Delayed tendon healing and tendon adhesions are still found to be among the complications that occur most often after tendon repair. Pistacia khinjuk is one of the three species of Pistacia growing in Iran. Objective: In this study, the role of local injection of ethanolic extract of P. khinjuk was evaluated in healing of the experimental Achilles tendon injury in rabbits. Metho...
