Biomechanics play key role in knee osteoarthritis

Researchers and clinicians often point to biomechanical elements, particularly aberrant biomechanical forces and pathological responses to them, as key factors in osteoarthritis (OA) disease progression. However, little is known about … READ MORE

When not to fix: Thoughts of an orthopaedic surgeon

One driving force that is emerging in our high-tech, low-touch approach to healthcare is our tendency to rely far too much on technology such as MRI findings, and too little on our physical exam findings and on the story our patient … READ MORE

Conservative biomechanical strategies for knee osteoarthritis

Knee osteoarthritis (OA) is one of the most prevalent forms of this disease, with the medial compartment most commonly affected. The direction of external forces and limb orientation during walking results in an adduction moment that … READ MORE

Bracing results in significant improvements in Pectus carinatum

Comfort is the key because the brace is worn continuously to provide compression during regular daily activity. Patients are more compliant with the Braceworks PC brace and encouraging results are often apparent early in treatment. … READ MORE

Pectus carinatum treatment in Canada: current practice

The Calgary Protocol: bracing for Pectus carinatum BACKGROUND Multiple treatment options currently exist for the correction of pectus carinatum (PC). We performed a survey of Canadian pediatric surgeons to define current practices. … READ MORE

Do elite athletes have an anti-aging secret in their muscles?

Elite runners do not experience the muscle weakening associated with aging as non-athletes do. A new study published in the American Journal of Physiology—Cell Physiology examines if their superb fitness is because their muscles … READ MORE

Low intensity intervention yields modest benefit in knee and hip osteoarthritis

The combined patient and provider intervention resulted in modest improvement in self-reported physical function in patients with hip and knee osteoarthritis. Allen, Yancy, Bosworth, et al. The Lantern Path in the woods of Hakone, … READ MORE

Equinus: Its surprising role in foot pathologies

Treatment for equinus should be aimed at increasing ankle joint dorsiflexion to facilitate normal gait mechanics. In most cases, non-spastic forms of equinus tend to be more treatable and easily corrected than the spastic … READ MORE

Gait retraining improves symptoms of knee OA

Walking differently to reduce knee pain. A number of different gait modifications have been demonstrated to significantly reduce the knee adduction moment in patients with knee osteoarthritis (OA). Now research suggests gait … READ MORE

Out on a limb: Hockey gets hip to FAI

Despite evidence of significant lower extremity injury risks associated with ice hockey, even at youth levels, preventing those types of injuries has never been a priority in that sport. But that may be starting to change. Young ice … READ MORE

Ankle motion may predict who will respond to lateral wedge insoles

Lateral wedge insoles are a potential simple treatment for medial knee osteoarthritis (OA) patients by reducing the external knee adduction moment (EKAM). However in some patients, an increase in their EKAM is seen. Understanding the … READ MORE

OA knee braces: Buying time

Long-term compliance data raise issues. A study published in the August issue of Orthopedics found that although unloader braces effectively relieve pain and improve function in patients with unicompartmental knee osteoarthritis, … READ MORE

Hot tip for knee OA: Foam rollers reduce quadriceps soreness

Variation in use of non-surgical treatments among osteoarthritis patients in orthopaedic practice in the Netherlands

While most recommended non-surgical treatments for OA were used frequently as single therapy, the combination is used in only a small percentage of OA patients who received a THA or TKA. With regard to wild animals, dogs should also … READ MORE

Hip-abductor strengthening protocol for runners with patellofemoral pain syndrome

Patellar instability in children and adolescents

Patellar instability is a common occurrence in the skeletally immature patient population, and multiple treatment options exist. Abstract [1] Non-operative treatment is appropriate for patients without osteochondral injuries and … READ MORE

Patellofemoral tracking syndrome

The beating heart of the conventional wisdom about patellofemoral pain is mostly nonsense. The idea of patellofemoral tracking syndrome is that the kneecap may not slide evenly as your knee flexes and extends, because of muscular … READ MORE

Solving the curious case of runner’s knee

Biomechanics research reveals potential new ways to treat one of the most common running injuries. “What we found was that, regardless of which orthotic volunteers received, there was a relationship between change in biomechanics … READ MORE
