Natural Aging of Biomaterials in Ambient and Physiological Environments

Advanced NanoBiomed Research, EarlyView.
Biomaterials used in biomedical applications can change their physical properties over time, even under ambient and physiological conditions. This review highlights key studies on the natural aging of materials ranging from soft hydrogels to metals and ceramics, emphasizing how time‐dependent changes influence function and performance.

Persistent Biomechanical Alterations After ACL Reconstruction Are Associated With Early Cartilage Matrix Changes Detected by Quantitative MR. [PDF]

, 2016
BackgroundThe effectiveness of anterior cruciate ligament (ACL) reconstruction in preventing early osteoarthritis is debated. Restoring the original biomechanics may potentially prevent degeneration, but apparent pathomechanisms have yet to be described.

Multimaterial Triphasic Scaffold Replicates Enthesis Microenvironment to Modulate Early Cell Responses

Advanced NanoBiomed Research, EarlyView.
A bioinspired triphasic scaffold integrating 3D printed polycaprolactone and electrospun poly(lactic‐co‐glycolic acid) is developed to replicate the organization of the tendon‐to‐bone enthesis. Cyclic mechanical stimulation induces spatially defined cell morphology and lineage‐related gene expression in human mesenchymal stem cells, highlighting the ...

New sonographically-guided test for anterior knee instability – preliminary report

Journal of Ultrasonography, 2014
Aim of the study: Ultrasound examination is widely used in orthopedic diagnostics, however sonographic evaluation of traumatic anterior cruciate ligament insufficiency is still inadequate. Aim of this study is to evaluate diagnostic capability of a new

Long‐Term Outcomes Following Anatomic Double‐Bundle Versus Single‐Bundle Anterior Cruciate Ligament Reconstruction Using Hamstring Autograft: A Randomized Controlled Trial With an Average 14‐Year Follow‐Up

Arthroscopy, EarlyView.
Purpose To compare the clinical and radiographic outcomes—particularly the long‐term development of osteoarthritis—14 years after anterior cruciate ligament (ACL) reconstruction between anatomic double‐bundle (DB) and anatomic single‐bundle (SB) techniques.

Editorial Commentary: Evidence Remains Elusive Regarding the Causal Effect of Delayed Posterior Cruciate Ligament Reconstruction on Intra‐articular Injury Incidence Due to Persistent Knee Instability

Arthroscopy, EarlyView.
Abstract Determining the optimal surgical timing for isolated posterior cruciate ligament (PCL) reconstruction remains challenging, particularly regarding the relationship between persistent instability and secondary intra‐articular pathology. Establishing causality between delayed reconstruction and intra‐articular injury prevalence is difficult due ...

Editorial Commentary: Focus on Quadrupled Grafts With a Thick Anteromedial Bundle in Double‐Bundle Anterior Cruciate Ligament Reconstruction Using Hamstring Tendon Autografts to Improve Graft Survival: Could We Define a Target Graft Diameter?

Arthroscopy, EarlyView.
Abstract The aim of double‐bundle anterior cruciate ligament reconstructions (DB ACLRs) is the reconstruction of anteromedial and posterolateral bundles of the ACL in order to achieve better rotational stability and improved functional results compared with single‐bundle ACLR techniques. Several studies described a considerable failure rate of DB ACLRs.

Smaller Lateral‐to‐Medial Tibial Plateau Ratios Are Strongly Correlative With Anterior Cruciate Ligament Tears and Reconstruction Failures

Arthroscopy, EarlyView.
Purpose To compare the anterior–posterior distance ratio of the lateral‐to‐medial tibial plateau (LTP/MTP) among 3 patient groups: those with intact anterior cruciate ligaments (ACLi), primary ACL tears (ACLp), and failed ACL reconstructions (ACLf).

Editorial Commentary: Beyond the Number: Why Return to Sport After Hip Arthroscopy Can't Be One Size Fits All

Arthroscopy, EarlyView.
Abstract This editorial commentary reflects on the evolving field of hip arthroscopy in the elite athlete and the growing recognition that return‐to‐sport outcomes cannot be captured by a “one‐size‐fits‐all” percentage. The heterogeneity we see in return‐to‐sport rates is not a flaw, but an authentic reflection of the athletes who we treat.
