Purpose: The aim of this study is to evaluate the impact of graft size and time between injury to surgery (TBIS) on static anterior tibial translation (SATT) and dynamic anterior tibial translation (DATT) after anterior cruciate ligament (ACL) reconstruction.
Methods: A consecutive series of patients treated with primary ACL reconstruction using hamstring autograft was reviewed. Preoperative SATT, DATT and posterior tibial slope (PTS) were measured with a previously validated technique by two independent reviewers on lateral weight-bearing knee radiographs. Regression analysis was performed to assess the relationship between postoperative-preoperative SATT difference (Δ SATT) and postoperative-preoperative DATT difference (Δ DATT) with graft size and TBIS.
Results: In total, 66 patients were included in this study. The mean preoperative SATT and DATT were 2.41 (standard deviation [SD] 2.98) and 9.09 (SD 3.19), respectively. The mean postoperative SATT and DATT were 2.14 (SD 2.47) and 5.28 (SD 2.55), respectively. The mean graft size was 8.4 mm (SD 8.4; range 7.75-10), and the median TBIS was 3 months (range 1-275). Linear regression analysis showed no correlation between graft size and Δ SATT ( = 0.060) and Δ DATT ( = 0.979) and no correlation between TBIS and Δ SATT ( = 0.817) and Δ DATT ( = 0.811).
Conclusion: Our results suggest that larger graft sizes or shorter times between injury and reconstruction do not impact the reduction of SATT or DATT following ACL reconstruction.
Level Of Evidence: Level IV, retrospective cohort study.

Background: Eden-Hybinette procedure can maximize the restoration of the glenoid defect by harvesting a proper size of iliac bone block. We developed an arthroscopic "double-inlay" Eden-Hybinette procedure to achieve better bone union of the graft. The aim of this study was to evaluate the clinical and radiological mid-term outcomes of the arthroscopic "double-inlay" Eden-Hybinette procedure for bone defects exceeding 20%.

Unexpected transmission of donor-derived diseases, including infections and malignancies, through organ transplantation are occasionally observed and reported. Subclinical, or otherwise undiagnosed, hematological malignancies in potential donors are rare events and typically not identifiable via standard donor evaluation or laboratory testing. Flow cytometric crossmatching (FCXM) is a specialized assay routinely performed in clinical histocompatibility laboratories for the evaluation of immunological compatibility between the recipients and the organ donors through the detection of donor-specific antibodies.

Objective: Bone grafts derived from natural hydroxyapatite (HA) are increasingly being explored because they are more economical in terms of production costs compared with commercial HA. HA can be obtained from local cattle slaughter waste in Aceh, Indonesia, which has not been widely studied for its potential for dental applications. This study examines the synthesis and characterization of bovine HA (BHA) derived from Aceh cattle femur through calcination for applications in dentistry.

Background: Bone defects, particularly in the mandible, pose significant clinical challenges due to the limited regenerative capacity. Effective bone tissue engineering requires biomaterials that promote both osteogenesis and angiogenesis. This study developed an optimized collagen-nano hydroxyapatite scaffold loaded with dexamethasone and stem cells to enhance bone regeneration.

To surmount the shortcomings of powder-based catalysts and small electrode sizes, the development of meter-scale integrated electrode materials is essential for practical electrocatalytic applications, which requires fine control over the effective surface grafting of catalytic active sites on large-size electrodes as well as addressing the challenge of balancing cost-effective and large-scale manufacturing with highly active and stable operation. Herein, we report a low-cost, facile, and scalable method for directly constructing meter-scale single-molecule-integrated catalytic electrodes using commercially available, flexible, and size-tailored conductive carbon textiles (e.g.
