Aquatic therapy soon after total knee arthroplasty improves outcomes

Opposite effect found after total hip arthroplasty in a new study in the Archives of Physical Medicine and Rehabilitation

Philadelphia, PA – Despite increased use of total hip arthroplasty (THA) and total knee arthroplasty (TKA), there is a notable lack of consensus about optimal postoperative treatment. Aquatic therapy has been shown to have a beneficial effect, and it is typically begun two weeks after surgery, after the wound has healed.

According to a new study published in the Archives of Physical Medicine and Rehabilitation, beginning aquatic therapy just 6 days after TKA may lead to improved results, while delaying its onset an additional week may be more appropriate after a THA.

"This multicenter study demonstrates that the timing of physiotherapy measures, such as aquatic therapy, has clinically relevant effects after TKA," says lead investigator Thoralf R. Liebs, MD, of the Department of Orthopaedic Surgery, University of Schleswig-Holstein Medical Center, Kiel, Germany. "Ours is one of the few studies that demonstrates a clinically important effect on the health-related quality of life after TKA by a factor that can be influenced by the healthcare professional. The intervention is simple to administer, and requires limited extra input from the health care professional."

THA and TKA patients were randomly assigned to receive aquatic therapy beginning either 6 days or 14 days after the procedure. In both groups, therapy lasted 30 minutes, three times a week, up to the fifth postoperative week. Physical function, pain, and stiffness were evaluated 3, 6, 12, and 24 months after the procedure.

After hip arthroplasty, all measurements at every follow-up period were better in the patients who began aquatic therapy after the wound had healed. In contrast, all mean outcomes were better in the group that began therapy 6 days after knee arthroplasty.

"THA has a high rate of patient satisfaction, and patients report an improved quality of life after the procedure. Additional interventions, such as early aquatic therapy, may not lead to much improvement," Dr. Liebs hypothesizes. "After TKA, patients are less satisfied, so the additional intervention has a greater effect. The hydrostatic force of water reduces effusion in the knee joint. Because the knee capsule is closed after TKA, reduced effusion leads to less pain. In THA, the joint capsule is not closed, so the effect of reduced effusion is less."

The article is "Multicenter Randomized Controlled Trial Comparing Early Versus Late Aquatic Therapy Following Total Hip or Knee Arthroplasty," by Thoralf R. Liebs, MD, Wolfgang Herzberg, MD, Wolfgang Rüther, MD, PhD, Jörg Haasters, MD, PhD, Martin Russlies, MD, PhD, Joachim Hassenpflug, MD, PhD, on behalf of the Multicenter Arthroplasty Aftercare Project, MAAP. It will appear in the Archives of Physical Medicine and Rehabilitation, Volume 93, Issue 2 (February 2012), published by Elsevier. doi:10.1016/j.apmr.2011.09.011.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
