Arthroscopy is a surgical technique useful in the treatment of intra- and extra-articular hip pathologies, including femoroacetabular impingement (FAI). In the arthroscopic treatment of pincer-type FAI, tendon interposition of the reflected head of the rectus femoris frequently hinders acetabular edge resection in the anterior-superior region (acetabuloplasty) and labrum repositioning, even cau...

Fracture of the calcaneal tuberosity with a concomitant Achilles tendon rupture presents a difficult challenge for the treating surgeon. The ultimate goal of treatment is to restore function of both the gastrocnemius-soleus complex and the Achilles tendon. This particular subset of fractures occurs often in diabetics and elderly patients with osteoporosis making fixation of the displaced fragme...

Distal biceps tendon ruptures are a result of an eccentric load onto a flexed elbow and can lead to loss of flexion and supination strength. Surgical treatment is a well-accepted treatment that can improve flexion and supination strength, however, can be associated with a number of surgical complications. The case presented here describes a vascular injury sustained during a distal biceps tendo...

Achilles tendon rupture in the dog is a common traumatic lesion. An accurate evaluation of etiology, grade of the lesion with or without loss of tendon substance, and time elapsed from the trauma can guide the surgeon in choosing the best surgical technique. Moreover, the healing process after a tendon injury is usually difficult and uncertain because the prognosis is influenced by extent of tr...

Tendon healing is slow and usually results in inferior fibrotic tissue formation. Recently, application of tendon derived stem cells (TDSCs) improved tendon healing in animal studies. In a chicken model, local injection of antioxidants reduced tendon adhesion after tendon injury. An in vitro study demonstrated that supplementation of H2O2 reduced tenogenic marker expression in TDSCs. These find...

O w large body of evidence supports the fact that ubluxation and dislocation of the long head of the iceps tendon are relatively common findings associted with rotator cuff pathology. Dislocation of the ong head of the biceps is often linked to chronic egenerative changes seen with impingement synrome and tears in the rotator cuff, especially the ubscapularis tendon. One report states that medi...

Injured adult tendons do not exhibit optimal healing through a regenerative process, whereas fetal tendons can heal in a regenerative fashion without scar formation. Hence, we compared FFs (mouse fetal fibroblasts) and AFs (mouse adult fibroblasts) as seed cells for the fabrication of scaffold-free engineered tendons. Our results demonstrated that FFs had more potential for tendon tissue engine...

  Background: Peritendinous adhesions after repairing an injury to the digital flexor tendons are a major problem in hand surgery. Non-steroidal anti-inflammatory drug therapy may affect tendon healing and the development of peritendinous adhesions. The aim of this study was to evaluate ibuprofen effect in patients function after flexor tendon surgical repair.   Method: Thirty-five patients, wh...

INTRODUCTION Surgical repair of tendon, including rotator cuff injury, are common procedures, however structural failure of the surgical repair is a common complication of the surgery, and in some instances there is a need to replace injured tendon. There is therefore a recognized need to generate tissue engineered tendons for repair and replacement of damaged or diseased tendon (Derwin et al, ...

BACKGROUND The recent discovery of residing tendon stem/progenitor cells has triggered a growing interest in stem cells as a useful tool in tendon repair. Our knowledge of their involvement in naturally healing tendons is, however, sparse. The aim of this study was to identify and determine stem/progenitor cells in relation to different healing phases and regions in a rat model of Achilles tend...
