Prospective randomised controlled trial comparing PLLA and PLDLA/HA/β‐TCP interference screws in anterior cruciate ligament reconstruction: CT scans, MRI and clinical outcomes

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Modifying interference screw composition may ensure better osteoconductive properties in order to reduce tunnel enlargement after anterior cruciate ligament (ACL) reconstruction. The primary and secondary purposes were to evaluate tunnel and screw volume changes in poly‐L‐lactide acid (PLLA) and poly‐D‐lactic acid + hydroxyapatite + β ...

Shape‐Memory Collagen/Silk‐Fibroin Scaffold for Dura Sealing and Skull Base Regeneration

Small, EarlyView.
ABSTRACT When a skull base defect occurs, reconstruction is typically performed using a variety of autologous grafts, flaps, or synthetic materials. Failure to achieve appropriate management and closure can lead to serious consequences, such as cerebrospinal fluid (CSF) leakage and subsequent meningitis.

Bone Grafts: Everything You Need to Know

Journal of Periodontal Research, EarlyView.
This review classifies bone grafts (autograft, allograft, xenograft, synthetic) by source and osteogenic/inductive/conductive potential, linking material properties and mechanisms to clinical indications in periodontal and dental regeneration. Key challenges—limited osteoinduction, poor vascularisation, unbalanced resorption, handling difficulties, and

Soft‐Tissue Integration of Dental Implants: Formation, Maintenance, and Relevance for Peri‐Implant Health

Journal of Periodontal Research, EarlyView.
Sixty years after the introduction of dental implants, it is clear that soft‐tissue integration is as essential as osseointegration. This review outlines how peri‐implant soft tissues develop, protect, and sometimes fail, revealing key knowledge gaps and new opportunities to improve long‐term implant stability.
