BACKGROUND Posterior Cruciate Ligament (PCL) ruptures are common sports injuries. One of the key controversies in PCL reconstruction is whether double-bundle reconstruction provides biomechanical and clinical outcomes superior to single-bundle reconstruction. METHODS We performed a comprehensive search in multiple databases to evaluate the advantages of single-bundle or double bundle reconstr...

BACKGROUND Single-incision anterior cruciate ligament reconstruction with a bone-patellar tendon-bone construct is commonly performed with 180 degrees rotation of the graft. It has been hypothesized that further rotation of the graft to 540 degrees can effectively shorten the graft to address graft length-tunnel mismatch. Initial biomechanical failure characteristics of rotated constructs have ...

BACKGROUND The majority of distal biceps tendon injuries can be repaired in a single procedure. In contrast, complete chronic tears with severe tendon substance deficiency and retraction often require tendon graft augmentation. In cases with extensive partial tears of the distal biceps, a human dermal allograft may be used as an alternative to restore tendon thickness and biomechanical integrit...

purpose : to investigate the correlation between corneal biomechanical properties and tomographic parameters of pentacam methods : corneal biomechanical properties and tomographic results of 36 normal subjects were measured by ocular response analyzer (ora) and pentacam and the correlation between these two measurements were analyzed with pearson correlation test with spss version16. results : ...

Hamstring autografts in anterior cruciate ligament reconstruction have an excellent clinical track record, but some patients have hamstring tendons that yield grafts of smaller diameter, which has been shown to be a significant risk factor for worse outcomes and graft failure. Some authors have advocated augmentation with allograft in these patients. Tripling the semitendinosus yields a complet...

Deep fascia is formed by a connective membrane that sheaths all muscles. It is devoid of fat, forms sheaths for the nerves and vessels, becomes specialized around the joints to form or strengthen ligaments, envelops various organs [1]. The fascia lata is the deep fascia of the thigh. It is often used as a graft material in a variety of orthopaedic procedures. Autologous nature of this graft eli...

BACKGROUND Acellular human dermal matrix grafts (Graftjacket; Wright Medical Technology, Arlington, TN, USA) are used clinically for rotator cuff augmentation without a detailed understanding of their biomechanical effects. The purpose of this study was to evaluate the effect of augmentation with dermal grafts on the biomechanical effects of rotator cuff repairs. METHODS Nine matched pairs of...

Graft remodeling following anterior cruciate ligament (ACL) reconstruction requires a long period of recovery in which vascular endothelial growth factor (VEGF) plays an important role. The short half-life of exogenous VEGF, however, restricts its use. The aim of this study was to investigate sodium hyaluronate (SH) as a delivery system for VEGF in graft revascularization. Non-cumulative releas...
