Using single femoral and tibial tunnels, we describe a technique of anatomically recreating the anteromedial and posterolateral anterior cruciate ligament (ACL) bundles. Transtibial, flexible reamers are utilized to create a "Figure 8" notched tunnel thereby recreating the anatomic footprint of the femoral insertion of the ACL. Rotational control of the individual bundles is created via the notched tunnel and each bundle is tensioned to 80 N individually. Anatomic double bundle ACL reconstruction is created in a reproducible modified single-bundle technique without the inherent risks associated with drilling four tunnels.

PurposeTo compare the clinical and radiological results of two double-bundle (DB) anterior cruciate ligament reconstruction (ACLR) techniques. DB ACLR and anterolateral ligament reconstruction (ALLR) with internal brace (IB), and outside-in (OI) DB ACLR.HypothesisWe hypothesized that DB ACLR and ALLR with IB wound yield less femoral tunnel, especially femoral posterolateral bundle tunnel complications, than OI DB ACLR without ALLR because of better rotational control.

Purpose: To compare graft synovialization and tear rates between autograft and allograft anterior cruciate ligament (ACL) reconstruction based upon second-look arthroscopy (SLA), along with joint stability, subjective and objective clinical outcomes.
Methods: A systematic search of PubMed, Embase and the Cochrane Library was conducted on 7 March 2025, to identify studies reporting graft synovial coverage and tear rates on SLA following primary ACL reconstruction. Meta-analyses were conducted using a random-effects model with logit transformation.

Hydrogels are soft and wet materials which require enhanced mechanical properties and toughness. For this aim, double-network hydrogels were prepared from soft network of covalently crosslinked hydroxypropyl guar and hard self-assembled network of carboxymethylated cellulose nanocrystals (CNCs) reversibly crosslinked by calcium ions. The gels exhibited a dramatic enhancement of mechanical strength and toughness with increasing content of CNCs and demonstrated remarkable fatigue resistance.

Fascin-1, an actin-bundling protein, plays a crucial role in cancer cell motility, invasion, and epithelial-mesenchymal transition (EMT). While its significance has been demonstrated in several malignancies, its clinical relevance in thymic carcinoma remains unclear. We retrospectively analyzed 10 surgically resected thymic carcinoma cases treated at Kochi University Hospital from 2008 to 2024.

Cancer-associated fibroblasts (CAFs) restructure collagen hydrogels via actomyosin-driven fibril bundling and crosslinking, increasing polymer density to generate mechanical stress that accelerates tumor proliferation. Conventional hydrogel models lack spatial heterogeneity, thus obscuring how localized stiffness gradients regulate cell cycle progression. To address this, we developed a collagen hydrogel-based microtissue platform integrated with programmable microstrings (single/double tethering), enabling real-time quantification of gel densification mechanics and force transmission efficiency.
