Background: Failure after rotator cuff repair is typically due to a loss of integrity of the bone-tendon interface. The BioWick anchor (Zimmer-Biomet) is an interpositional scaffold-anchor that was developed to improve tendon-bone healing. The purpose of this study was to determine the clinical efficacy of this novel anchor compared with a standard anchor with respect to retear rates and patient outcomes.

Bioresorbable scaffolds (BRS) were developed as an innovative solution to overcome the limitations of metallic stents. While polymeric BRS initially demonstrated comparable clinical outcomes to drug-eluting stent (DES) in clinical trials, subsequent large-scale studies revealed that patients implanted with polymeric BRS experienced higher rates of scaffold thrombosis (ScT) and target lesion failure compared to those with metallic stents. Resorbable magnesium scaffolds (RMS) have emerged as a promising alternative owing to magnesium's natural degradability and favorable mechanical properties.

Bone defects and fractures present significant clinical challenges, particularly in orthopedic and maxillofacial applications. While minor bone defects may be capable of healing naturally, those of a critical size necessitate intervention through the use of implants or grafts. The utilization of traditional methodologies, encompassing autografts and allografts, is constrained by several factors.

Biodegradable polymers and bioceramics give rise to composite structures that serve as scaffolds to promote tissue regeneration. The current research explores the preparation of biodegradable filaments for additive manufacturing. Bioresorbable segmented poly(ester urethanes) (SPEUs) are easily printable elastomers but lack bioactivity and present low elastic modulus, making them unsuitable for applications such as bone tissue engineering.

Article Synopsis
- This study aimed to explore new scaffold geometries for improving the mechanical performance of Poly-L-lactic Acid (PLLA) bioresorbable vascular scaffolds (BVS) using finite element analysis (FEA) and lab experiments.
- Four different scaffold designs were subjected to simulations and tests, focusing on various mechanical properties like crush resistance and radial strength.
- The results revealed that Design B outperformed others in key performance metrics, suggesting new PLLA scaffold geometries could enhance their use in cardiovascular applications.
