Chronic knee pain: Is surgery the only solution?

13.12.2007
The results of a study published in the online open access journal, BMC Medicine indicate that sufferers of chronic patellofemoral syndrome (PFPS), a chronic pain in the front part of the knee, gain no extra benefit from surgery.

Furthermore, the authors suggest that giving these patients a therapeutic exercise regime rather than putting them through surgery could save money.

Patellofemoral pain syndrome is often treated with arthroscopic surgery, in which equipment inserted through small incisions in the knee is used to both diagnose the cause of the problem and attempt to fix it.

Jyrki Kettunen of The ORTON Research Institute, in Helsinki, Finland, and colleagues point out that whilst chronic knee pain is a common complaint, there is a lack of evidence that arthroscopic surgery has a better outcome than other forms of treatment including therapeutic exercise.

The team conducted a randomized controlled trial to study the efficacy of arthroscopy compared with exercise in 56 patients with chronic PFPS.

The patients were randomly divided into two groups; the first group was treated with knee arthroscopy and an eight-week home exercise program and the second group was treated with the exercise program only. The researchers assessed the patients after 9 months using the Kujala score for knee pain and mobility. They also estimated the direct healthcare costs per patient.

The researchers found that patients in both groups experienced reduced pain and showed marked improvement in knee mobility, with no significant difference in the average Kujala score between the two groups. Other tests also revealed that the improvements for patients treated with surgery and exercise were almost exactly the same as for the exercise-only patients. However, the average cost of treatment was €901 ($1,333.46) higher per patient who underwent both arthroscopy and exercise therapy.

The researchers also carried out a second follow up at two years and still found no differences in outcome between the two patient groups. They concluded that arthroscopy is not a cost effective treatment for chronic PFPS and that surgery should not be routinely used to treat the condition.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
