Two separate new studies presented at a major medical meeting provide objective scientific evidence that the two most commonly performed cartilage repair techniques are effective at restoring patient mobility and reducing pain.
Patients in both studies, those that had a cartilage and bone grafts and those that had a procedure that encouraged new tissue growth, recovered more knee function and experienced less pain after the procedure. Prior to these results, surgeons had no evidence – apart from their own observations and experience – that these commonly practiced surgeries were effective. "The research conducted was a prospective analysis of randomly selected patients who sought treatment to repair cartilage damage. One study looked at patients who had osteochondral allograft, while the other followed-up with patients who had a microfracture procedure," said Riley Williams, MD, a co-author of the study and Director of the Hospital for Special Surgerys Institute for Cartilage Repair.
Dr. Williams added that the results of both studies will help doctors to more accurately predict outcomes for patients seeking relief from cartilage pain. Dr. Williams presented the research at American Academy of Orthopedic Surgeons (AAOS) annual meeting, February 23-26, 2005 in Washington, DC. The results of "The Microfracture Technique for Treatment of Articular Cartilage Lesions in the Knee: A Prospective Cohort Evaluation," were presented on Specialty Day, February 26th. "A Prospective Analysis of Knee Cartilage Defects Treated with Fresh Osteochondral Allografts," was on exhibit in a scientific poster throughout the event.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
