3D PRINTING OF FOOT ORTHOSES: Clinical feasibility and cost-benefit analyses

Several technical issues currently limit the cost effectiveness of 3D-printing custom foot orthoses, but these will likely be addressed in the near future with the emergence of larger and faster 3D printers.

LER Pediatrics

Sports in the tiger-parenting era: It doesn’t surprise me that focusing on achievement in a single sport at a young age substantially raises the risk of overuse injuries and can lead to other physical and developmental issues.

But experts quoted in our current feature (See “Early athletic specialization: Misconceptions and hazards,” page 15) brought up some less intuitive points about the increasingly common practice of intense concentration on a single sport at a young age.

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.

Basketball shoe trends favor fashion over feet

Several confounding factors make it difficult to determine statistical associations between footwear and injuries in basketball, but attitudes toward shoes among National Basketball Association (NBA) players suggest both positive and negative trends with regard to potential injury risk.

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.
