Relevance . Autografts are nowadays the gold standard for soft tissue augmentation and gingival recession coverage. However, as this method has a number of significant disadvantages, xenografts various origins more frequently used in dental practice. The study aimed to conduct comparative morphological assessment crosslinked non-crosslinked xenogenous scaffold biointegration quality at differen...

We describe GaAs-based tunnel junctions that are compatible with photonic devices, including long-wavelength vertical-cavity surface-emitting lasers and multi-junction solar cells. Tunneling was enhanced with semimetallic ErAs nanoparticles, particularly when grown at reduced substrate temperatures. Additionally, we present the first direct measurement of the quality of III-V layers grown above...

We describe a surgical case of coronary-coronary bypass grafting using the saphenous vein for revascularization of the right coronary artery during concomitant graft replacement of the ascending aorta. This technique of coronary revascularization can be used as an alternative to avert the need for a prosthetic graft to coronary artery bypass grafting in cases with potential problems of anastomo...

Background It has been shown that the proper placement of ACL graft during the ACL reconstruction surgery significantly improves the clinical outcomes. This study investigated whether a change in the femoral tunnel position in both axial and coronal planes can significantly alter the postoperative functional and clinical outcomes of the patients. Methods This comparative, retrospective, singl...

PURPOSE To systematically review the current evidence for the effects of platelet concentrates on (1) graft maturation and (2) graft-bone interface healing in anterior cruciate ligament (ACL) reconstruction in human, controlled trials and for ensuing differences in clinical outcomes. METHODS A systematic search of PubMed, CINAHL (Cumulative Index to Nursing and Allied Health Literature), Emba...

There is little evidence examining the relationship between anatomical landmarks, radiological placement of the tunnels and long-term clinical outcomes following anterior cruciate ligament (ACL) reconstruction. The aim of this study was to investigate the reproducibility of intra-operative landmarks for placement of the tunnels in single-bundle reconstruction of the ACL using four-strand hamstr...

PURPOSE To perform a systematic review of the described anterolateral ligament (ALL) reconstruction techniques, biomechanical performance, and clinical outcomes of ALL reconstruction in the setting of concurrent anterior cruciate ligament (ACL) reconstruction. METHODS A systematic review was performed according to PRISMA guidelines using the Cochrane Database of Systematic Reviews, the Cochra...

Skin grafting is the easiest and the most reliable way to obtain proper wound coverage. However, the two major concerns of skin grafting are the poor color match in the recipient sites and donor site morbidity including pain, discomfort, and hypertrophic scarring. Major pigment mismatches are common in split-thickness grafts particularly in darker skinned patients including Asians (Fig. 1). Sev...

PURPOSE The purpose of this study was to compare four graft-tunnel angles (GTA), the femoral GTA formed by three different femoral tunneling techniques (the outside-in, a modified inside-out technique in the posterior sag position with knee hyperflexion, and the conventional inside-out technique) and the tibia GTA in 3-dimensional (3D) knee flexion models, as well as to examine the influence of...

PURPOSE To evaluate the insertion torque of a soft-tissue interference screw in relation to depth of insertion into the tibial tunnel when used for fixation of a quadrupled semitendinosus-gracilis autograft in anterior cruciate ligament reconstruction. TYPE OF STUDY Biomechanical cadaver study. METHODS Ten quadrupled semitendinosus-gracilis grafts were harvested from fresh-frozen cadaver kn...
