purpose: to compare intraocular pressure (iop) readings measured by the ocular response analyzer (ora) with those measured by the goldmann applanation tonometer (gat) in keratoconic eyes following penetrating keratoplasty (pkp) and to evaluate the influence of anatomical and biomechanical properties of the grafts on iop measurements. methods: this cross-sectional study was conducted on 45 kerat...

Osteochondral grafting for cartilage lesions is an attractive surgical procedure; however, the clinical results have not always been successful. Surgical recommendations differ with respect to donor site and graft placement technique. No clear biomechanical analysis of these surgical options has been reported. We hypothesized that differences in graft placement, graft biomechanical properties, ...

Graft necrosis following ACL reconstruction is often associated with the use of autologous grafts. Host cells rather than graft cells contribute to the repair of the tendon-bone interface and the remodeling of the autologous graft. The native tendon-bone interface is not recreated and the biomechanical properties are not restored back to native values. We examined the effects of introducing gap...

BACKGROUND Numerous surgical techniques have been described to address injuries to the coracoclavicular ligaments. PURPOSE To compare the biomechanical properties of tendon graft reconstructions with those of the native coracoclavicular ligaments and various other repair methods. STUDY DESIGN Controlled laboratory study. METHODS Eleven fresh-frozen human cadaveric shoulders were tensile t...

purpose: to investigate the biomechanical features of transplanted corneas after penetrating keratoplasty (pk), deep anterior lamellar keratoplasty (dalk), and descemet stripping automated endothelial keratoplasty (dsaek) and compare these measurements with those of a normal group. methods: forty-five eyes of 36 patients underwent pk, 23 eyes of 21 patients received dalk using anwar’s big bubbl...

Aneurysm of the aorta is currently treated by open surgical repair or endovascular repair. However, when the aneurysm occurs in regions between the aortic arch and proximal descending aorta, it can be a complex pathology to treat due to its intricate geometry. When complex aortic aneurysms are treated with the conventional procedures, some of the patients present with significant post-operative...

BACKGROUND The aim of this study was to determine if anterior cruciate ligament (ACL) reconstruction by remnant preservation promotes cell proliferation, vascularization, proprioception recovery, and improved biomechanical properties of the tendon grafts. MATERIAL AND METHODS 75 New Zealand rabbits were randomly assigned into the control group (group A), conventional ACL reconstruction group (g...

Introduction: Over 200,000 anterior cruciate ligament reconstructions (ACLR) are performed in the United States yearly, making it one of the most common orthopedic procedures. Graft choices for ACLR include both autograft and allograft tendons. The most popular autograft choices are the bone-patellar tendon-bone (BPTB) and hamstring (HS) tendons. While the BPTB has long been considered “the gol...
