Five-year follow-up – over half of all ACL reconstructions could be avoided

30.01.2013
In the summer of 2010, researchers from Lund University in Sweden reported that 60 per cent of all anterior cruciate ligament (ACL) reconstructions could be avoided in favour of rehabilitation.

The results made waves around the world, and were met with concerns that the results would not hold up in the long term.

Now the researchers have published a follow-up study that confirms the results from 2010 and also show that the risk of osteoarthritis and meniscal surgery is no higher for those treated with physiotherapy alone.

“We have continued with our study and for the first time are able to present a five-year follow-up on the need for and results of ACL surgery as compared with physiotherapy. The findings have been published in the British Medical Journal and are basically unchanged from 2010. This will no doubt surprise many people, as we have not seen any difference in the incidence of osteoarthritis”, says Richard Frobell, one of the researchers behind the study, who is an associate professor at Lund University and a clinician at the orthopaedic department, Helsingborg Hospital.

Richard Frobell explains that the research group’s results from 2010*, which were published in the New England Journal of Medicine, caused a stir and questions were raised as to whether it was possible to say that an operation would not be needed in the long term.

Half of the patients who were randomly assigned not to undergo reconstructive surgery have had an operation in the five years since, after experiencing symptoms of instability.

“In this study, there was no increased risk of osteoarthritis or meniscal surgery if the ACL injury was treated with physiotherapy alone compared with if it was treated with surgery. Neither was there any difference in patients’ experiences of function, activity level, quality of life, pain, symptoms or general health”, says Richard Frobell.

“The new report shows that there was no difference in any outcome between those who were operated on straight away, those who were operated on later and those who did not have an operation at all. The message to the medical experts who are treating young, active patients with ACL injuries is that it may be better to start by considering rehabilitation rather than operating straight away.”
In Sweden, over 5 000 people every year suffer an anterior cruciate ligament injury – mainly young people involved in sport. There are different schools of treatment and Sweden stands out with treatment that is in line with the results of the study.

“On an international front, almost all of those with ACL injuries are operated on. In Sweden, just over half are operated on, but in southern Sweden we have been working for many years to use advanced rehabilitation training as the first method of treatment. Our research so far has confirmed that we are right in not choosing to operate on these injuries immediately. Longer-term follow-up is important, however, if we are to look more closely at the development of osteoarthritis in particular”, says Richard Frobell.

The research group, whose study is called KANON, Knee ACL NON-operative versus operative treatment, is now moving on to the next stage. This year, the third part of the study will begin, following up the patients ten years after anterior cruciate ligament injury.

Richard Frobell has also entered into a collaboration with researchers at the School of Economics and Management at Lund University to evaluate the health economics aspects of different treatment methods for ACL injury.

Im Focus: Electron highway inside crystal

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.

Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...

Im Focus: Significantly more productivity in USP lasers

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:...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

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...

Im Focus: Quantum Particles Form Droplets

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...
