AIM To quantitatively assess rotatory and anterior-posterior instability in vivo after anterior cruciate ligament (ACL) reconstruction using bone-patellar tendon-bone (BTB) autografts, and to clarify the influence of tunnel positions on the knee stability. METHODS Single-bundle ACL reconstruction with BTB autograft was performed on 50 patients with a mean age of 28 years using the trans-tibia...

BACKGROUND Between 5 and 20% of patients undergoing ACL reconstruction fail and require revision. Animal studies have demonstrated slower incorporation of allograft tissue, which may affect the mechanism of graft failure. The purpose of this study is to determine the location of traumatic graft failure following ACL reconstruction and investigate differences in failure patterns between autograf...

INTRODUCTION The field of medicine as a formal discipline has been traced by many to Imhotep and his descriptions of ailments and treatments found written on papyrus and translated in the mid-1800s by Edwin Smith [1]. Among the medical descriptions included in Imhotep’s writings are cervical dislocations, skull fractures, and compound fractures [1]. Indeed, mummies found in Egyptian tombs have ...

Background Quadrupled (4-strand) hamstring tendon autografts are commonly used in anterior cruciate ligament (ACL) reconstruction, but there is significant variability in their diameter. The 5-strand hamstring autograft has been used as a means of increasing the graft diameter in patients with undersized hamstring grafts. Purpose To report the outcomes of primary ACL reconstruction using 5-st...

BACKGROUND Anterior cruciate ligament (ACL) reconstruction with hamstring autografts less than 8.5 mm in diameter is associated with worse patient-reported outcome scores and increased risk of revision surgery compared with reconstructions performed with larger grafts. One proposed solution to small autograft harvest is to create a hybrid graft by augmenting autografts with allograft tissue to ...

BACKGROUND There are advantages to using homografts and autografts as aortic valve replacements, particularly in patients with infective endocarditis. To better define these advantages, we reviewed our 13-year experience with the surgical management of infective endocarditis involving the aortic valve and root. METHODS From 1986 through 1998, 81 adults with aortic valve endocarditis underwent...

BACKGROUND Among various reconstruction methods after wide excision for osteosarcoma, pasteurized autograft is often preferred. While the whole area of the tumor can be assessed for chemotherapy-induced necrosis, one of the important prognostic factors, in other reconstructive techniques, only a portion removed from a wide-resection specimen is available when using pasteurized autograft method....

AIM To analyse data on bone augmentation at single-tooth implants with regard to the type of graft materials, the stability of grafts over time, reported time span towards implant placement, implant survival rates, implant marginal bone maintenance and possible complications. MATERIAL AND METHODS A literature review resulted in 585 titles after exclusion of duplicates. Analyses of article tit...

Biomineralization Article 2200976 by Luiz E. Bertassoni and co-workers presents injectable cell-laden bone-like tissue constructs that show promise as minimally invasive growth factor-free alternatives to bone autografts for repair regeneration of critical sized defects. By approximating the cellular, structural, chemical composition native bone, engineered microconstructs promote native-like m...
