Numerous studies have reported alterations in skeletal muscle properties and phenotypes in response to various stimuli such as exercise, unloading, and gene mutation. However, a shift in muscle fiber phenotype from fast twitch to slow twitch is not completely induced by stimuli. This limitation is hypothesized to result from the epigenetic differences between muscle types. The main purpose of t...

  Tears of the subscapularis tendon have been significantly recognized as a source of shoulder pain and dysfunction in the past decade, thanks to arthroscopic evaluation of the shoulder and biomechanical and anatomical studies of the tendon. Current classification of subscapularis tendon tear is based on insertion site of the tendon. Recently, a classification for non-insertional types of subsc...

Introduction: Since palmaris longus tendon is the first choice for grafting, its anatomical variation is important. This study was designed to find the anatomical variations of this tendon in Iranian population by performing a study on cadaver. Method: In this study, 150 forearms belonged to 75 cadavers were studied. After exploring the proximal end of tendon, tendon width was measured at its p...

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: A potential specific problem of patellar tendon graft in ACL reconstruction is the possibility of graft-tunnel mismatch which could be more problematic with anatomic ACL reconstruction where the femoral tunnel is placed low on the lateral wall of the lateral femoral condyle. The occasional occurrence of this mismatch raises the question that whether a correlation exists between pat...
