Effects of Vitamin E-Stabilized Ultra High Molecular Weight Polyethylene on Oxidative Stress Response and Osteoimmunological Response in Human Osteoblast

Frontiers in Endocrinology, 2019
High Crosslink process was introduced in the development of joint prosthetic devices, in order to decrease the wear rate of ultrahigh molecular weight polyethylene (UHMWPE), but it also triggers the formation of free radicals and oxidative stress, which ...

The Tendon‐to‐Bone Seam: A Transtendinous Approach to Rotator Cuff Repair

Arthroscopy Techniques, EarlyView.
Abstract This technique article describes the tendon‐to‐bone seam technique, a knotless, transtendinous approach to arthroscopic rotator cuff repair. The technique employs a single‐use deployment device preloaded with multiple PEEK anchors interconnected with a single polyethylene #2 suture, enabling the surgeon to create a continuous “seam” of ...

Transtibial Anterior Cruciate Ligament Reconstruction Using a Synthetic Graft Combined With Remnant Repair: A Hybrid Technique

Arthroscopy Techniques, EarlyView.
Abstract The purpose of this technical note is to describe a hybrid arthroscopic technique that combines anterior cruciate ligament reconstruction using a synthetic graft with concomitant remnant repair. Following diagnostic arthroscopy and assessment of remnant quality, tibial and femoral tunnels are created using a transtibial approach with attention

Arthroscopic All‐Inside/All‐Suture Repair of Complete Radial Tear of the Lateral Meniscus Using a Percutaneous Single‐Needle Technique

Arthroscopy Techniques, EarlyView.
Abstract Radial tears of the lateral meniscus have limited healing potential and unfavorable biomechanics, and current suture constructs that use capsular rip‐stop stitches may increase meniscal extrusion and constrain native motion. This technical note describes an all‐inside, crossed, meniscus‐based repair for complete or near‐complete radial tears ...

Nonthermal plasma approaches for combating implant‐associated infections: A compendious review

VIEW, EarlyView.
Implant‐associated infections pose serious clinical challenges. Non‐thermal plasma (NTP) modifications overcome this bottleneck in distinct ways relative to traditional sterilization methods. Gas‐phase plasmas generate highly energetic species, UV radiation and reactive oxygen/nitrogen species (RONS), which alter the implant surface properties.
