Pressure-based diabetic footwear modifications reduce plantar loads

Shoe modifications based on plantar pressure measurements in patients with diabetic neuropathy can substantially reduce regional elevated loading associated with ulceration risk, according to research from the Netherlands. Investigators from the University of Amsterdam analyzed dynamic plantar pressures in 23 … Continue reading

OA bracing: Spin class

Rotation may be key to pain relief
Research from the Hospital for Special Surgery  in New York City confirms that the kinetic effects of osteoarthritis knee bracing are in fact related to bracing’s effects on knee pain—but not in the way investigators had expected.

Dorsiflexed AFO alignment improves gait variables in post-stroke patients

An ankle foot orthosis that orients the ankle in slight dorsiflexion may help improve knee flexion during gait and reduce the risk of heel ulcers in post-stroke patients, according to research from Marquette University in Milwaukee. Investigators performed gait analysis … Continue reading

Forefoot plantar pressures respond to rocker bottom diabetic footwear

A Mayo Clinic study confirms previously reported offloading effects of a rocker bottom shoe design in patients with diabetic neuropathy and suggests that a plastazote insole may increase that benefit. Researchers analyzed dynamic plantar pressures in 15 subjects with diabetic … Continue reading

Strengthening for Achilles tendinosis affects medial but not lateral gastroc

Eccentric strength training of the plantar flexors in patients with Achilles tendinosis results in remodeling of the muscle architecture in the medial gastrocnemius not seen in the lateral gastrocnemius, according to a study from Columbus, OH. Researchers at the Orthopedic … Continue reading

Study of Charcot patients suggests BMD does not improve with time

Research from the University of Pittsburgh Medical Center suggests that, surprisingly, calcaneal bone mineral density does not improve with time following the onset of Charcot neuroarthropathy in patients with diabetes. Investigators analyzed BMD at a single time point in 10 … Continue reading

Pair walking boot with athletic shoe to decrease contralateral pressures

Pairing a walking boot with an athletic shoe effectively offsets the elevated contralateral peak plantar pressures that can result from the limb length discrepancy created by the boot, according to research from Midwestern University in Glendale, AZ. The investigators analyzed … Continue reading

Hip flexion-extension ratio findings have implications for design of RGOs

Optimization of reciprocating gait orthoses to maximize function should involve attention to hip flexion-extension ratios, which differ significantly between locked and free joint conditions, according to research from Taiwan presented in March at the annual meeting of the American Academy … Continue reading

Can hip IR predict FAI?

Physical exam could be used to screen
Physical exam findings including hip range of motion can be used to help screen athletes for femoroacteabular impingement even before symptoms occur, according to research presented in February at the annual meeting of the American Academy of Orthopaedic Surgeons.

Positives for Ponseti

Gait study compares clubfoot care
Children with clubfoot treated with the Ponseti casting method have less pain and better function five to 10 years later than those treated surgically, according to gait analysis research from Baltimore that provides evidence to help justify the growing popularity of conservative clubfoot care.

Meta-analysis underscores benefits of early motion after Achilles rupture

A Canadian meta-analysis presented at the AAOS meeting confirms that early mobilization after Achilles tendon rupture essentially negates the difference in re-rupture rate between operative and nonoperative treatments. Most meta-analyses of operative vs nonoperative management of Achilles rupture, including a … Continue reading

Limited ROM after ACL reconstruction linked to radiographic osteoarthritis

Radiographic evidence of osteoarthritis five years after anterior cruciate ligament reconstruction is significantly more likely in patients with limited range of motion—even by just a few degrees—in the operated knee, according to research presented at the AAOS meeting. Investigators from … Continue reading

Mortality data favor transmetatarsal amputation in patients with diabetes

Transmetatarsal amputations offer lower mortality rates and time to failure than other distal alternatives to transtibial amputation in patients with diabetes, according to research from the University of Rochester in New York. Investigators retrospectively reviewed records of 83 patients who … Continue reading
