Activity level may predict orthopedic outcomes

23.07.2014

According to a literature review in the July issue of the Journal of the American Academy of Orthopaedic Surgeons (JAAOS), patients' activity level is a strong predictor for how well they will do with certain treatments and how well they recover from injuries after treatment.

Patients are encouraged to ask their orthopaedic surgeon if activity level is an important factor in their treatment decision. For example, more active patients are at a higher risk of re-injury after an anterior cruciate ligament (ACL) reconstruction, and activity level should be considered when deciding which graft to use in the ACL repair.

Easily administered, standardized scales for the shoulder, hip, knee and ankle are commonly used in orthopaedics to quantify a patient's activity level. But, the measures of how often, rather than how well, a task is performed do not account for symptoms, functional disabilities, age, weight, overall health and other factors which also may impact prognostic and outcome variables.

"In orthopaedics, we want to restore function to take away pain and to help patients return to activity," said orthopaedic surgeon and lead study author Robert H. Brophy, MD. "We're still learning about how to best use, quantify and measure activity levels to optimize prognostics and outcomes."

Other literature review highlights:

Shoulder

  • The strongest predictors for failure in rotator cuff tears were patient expectations on the efficacy of physical therapy and baseline activity level.

     

  • After a rotator cuff tear, patients who were active were less likely to respond to nonsurgical treatment.

Hip

  • Preoperative activity levels, age, male gender and lower body mass index (BMI) were predictors of higher activity level at one and five years following total hip replacement surgery.

     

  • Physical activity—including occupational lifting and standing—may accelerate the development and increased risk of osteoarthritis (OA).

Knee

  • Higher baseline activity, lower baseline BMI and higher level of athletic competition were associated with higher activity levels two years after ACL reconstruction.

     

  • Female gender, smoking in the 6-month period before surgery, and revision ACL reconstruction were associated with lower activity level.

     

  • Following ACL reconstruction, patients were significantly less satisfied if they had a lower post-surgical activity level.

     

  • Increased incidences of knee injury and trauma in the athletic population, rather than participation in physical activity, may cause an increased risk of knee OA.

     

"There's not just one activity level variable" in these measurements, said Dr. Brophy. "It depends on the population, the injury you're studying, etc. We're making progress, and the progress varies depending on what you're looking at."

Im Focus: Basel Physicists Develop Efficient Method of Signal Transmission from Nanocomponents

Physicists have developed an innovative method that could enable the efficient use of nanocomponents in electronic circuits. To achieve this, they have developed a layout in which a nanocomponent is connected to two electrical conductors, which uncouple the electrical signal in a highly efficient manner. The scientists at the Department of Physics and the Swiss Nanoscience Institute at the University of Basel have published their results in the scientific journal “Nature Communications” together with their colleagues from ETH Zurich.

Electronic components are becoming smaller and smaller. Components measuring just a few nanometers – the size of around ten atoms – are already being produced...

Im Focus: Into the ice – RV Polarstern opens the arctic season by setting course for Spitsbergen

On Tuesday, 19 May 2015 the research icebreaker Polarstern will leave its home port in Bremerhaven, setting a course for the Arctic. Led by Dr Ilka Peeken from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) a team of 53 researchers from 11 countries will investigate the effects of climate change in the Arctic, from the surface ice floes down to the seafloor.

RV Polarstern will enter the sea-ice zone north of Spitsbergen. Covering two shallow regions on their way to deeper waters, the scientists on board will focus...
