Protecting hip implants: Gait patterns help predict wear rates

Patient-specific implant wear rates following total hip arthroplasty (THA) are more strongly associated with gait patterns than component positioning, according to research from Chicago that suggests implant wear could be reduced with the use of predictive wear models.

From prints to prison: Forensic podiatry and gait analysis gain ground

Increasingly, lower extremity experts are being called on to assist with crime scene investigations by analyzing footprints, shoe prints, and the gait patterns of shadowy figures on security videos. For members of this fledgling field, as Sherlock Holmes famously said, the game is afoot.

Rocker-bottom footwear: effects on balance, gait

Footwear with rocker soles are best known for helping to redistribute plantar pressures during gait in patients with diabetes, but research suggests they also have clinically relevant effects on balance and gait that can be beneficial for some populations but potentially dangerous for others.

Knee OA in amputees: Biomechanical and technological considerations

The risk of knee osteoarthritis in the intact limb of longtime unilateral amputees is much higher than in non­amputees, and the range of potential contri­buting factors is even more complex. Optimizing prosthetic fit and function, in addition to more conventional OA interventions, can help address gait issues that contri­bute to knee joint degeneration.

Does history of running protect against knee OA?

Running may increase the risk of knee osteoarthritis (OA) onset or progression for some people, but in many others the knees will be safe during running; in such individuals, the benefits of physical activity can positively affect weight management and other means of reducing OA risk.

Managing O&P patients who are hard on devices

Even patients who obediently wear their O&P devices can pose a clinical challenge if they wear their devices past the point of breakdown. Experts offer suggestions for dealing with patients who are hard on devices—including those who are very large, very active, or very frugal.

Jump mechanics and risk of patellar tendinopathy

To understand the association between jumping biomechanics and transmission of forces through the patellar tendon, practitioners must have a working knowledge of the anatomy of the knee, as well as the biomechanical factors that determine force transmission through the knee.

Stiffer shoes improve running energetics as long as first MTP flexion is preserved

Increasing running shoe bending stiffness helps improve running energetics up to the point at which it impairs metatarsophalangeal (MTP) joint flexion—a threshold that varies between individuals—according to research from the Republic of Korea.

Patellofemoral pain subgroups: A critical first step toward personalized clinical intervention

Researchers from the UK have identified three subgroups of individuals with patellofemoral pain (PFP) that can be determined using simple evidence-based clinical tests—a key first step toward developing targeted treatment strategies as part of the ongoing effort to improve PFP outcomes.

Influence of mental health on diabetic foot outcomes

As evidence accumulates suggesting negative effects of depression, dementia, and other mental health issues on gait and foot-related outcomes in people with diabetes, researchers are looking at ways to screen for risk factors and psychosocial issues earlier in the continuum of care.

The role of hip extensor strength during cutting

Although most clinicians tend to emphasize hip abductor and external rotator muscle  strengthening in injury prevention and rehabilitation, recent research suggests exercises to increase explosive hip extensor strength may be critical for controlling frontal plane motion during cutting tasks.

Soccer gets safer: Injury trends suggest prevention payoff

Collegiate soccer injuries, particularly those at the knee and in women, decreased significantly from the early 1990s to the late 2000s, according to research from George Washington University in Washington, DC. The positive trends may reflect an increase in resources being allocated toward injury prevention along with…

Focused young company grows closer to becoming internationally recognized footwear brand

Ten years ago, the U.S. orthopedic medical community had never heard of Vionic shoes. That’s no surprise, as Vionic’s fashion-forward line of orthotic footwear marched into the market in 2007. Since then, the groundbreaking shoes for men and women have taken the orthotic and comfort shoe markets by storm. Continue reading

Peroneal tendinopathy management in tennis

Although not as common as Achilles tendinitis, peroneal tendinitis is seen in a certain group of patients with chronic ankle instability or with a cavovarus foot.1 Peroneal tendinitis presents as lateral foot pain and may also be of unknown etiology or associated with an acute inversion injury.

AFO stiffness can help optimize patient function

Decisions related to the stiffness of an ankle foot orthosis (AFO)—whether they involve device design or the materials from which it’s fabricated—can help lower extremity clinicians customize stability, biomechanics, and muscle function to meet individual patients’ needs.

Adjacent-joint arthritis after ankle arthrodesis

Altered biomechanics after ankle arthro­desis often increase stress on the adjacent joints in the foot, which can cause or exacerbate osteoarthritic degeneration in those joints. Clinicians and researchers are working to better understand this process and how to minimize patients’ risk.

ITBS intrigue: Fatigue leads to decreased hip adduction

Women with iliotibial band syndrome (ITBS) independently modify their running gait when fatigued to decrease hip adduction, potentially as a result of pain, according to research from Rutgers University in Newark, NJ, that may have implications for gait retraining.
