Bone bruises and risk of knee osteoarthritis

Bone bruises are commonly associated with anterior cruciate ligament (ACL) tears, but researchers are only beginning to understand the potential clinical significance of these chondral lesions with regard to knee osteoarthritis (OA) and preventing ACL injury recurrence.

The role of varus thrust in knee osteoarthritis

Varus thrust is a characteristic of dynamic alignment that has been shown to be predictive of medial tibiofemoral structural progression. Treatments aimed at minimizing varus thrust may reduce structural progression and symptoms related to knee osteoarthritis.

Whole body vibration for knee osteoarthritis

Whole body vibration may help improve strength and function in patients with knee osteoarthritis and may even slow disease progression. But contradictory findings, a lack of consensus on optimal parameters, and safety issues have even WBV advocates proceeding with caution.

Hip strength deficits characterize both patellofemoral pain and osteoarthritis

Patellofemoral osteoarthritis (PFOA) is associated with deficits in hip abduction strength, a similarity to patellofemoral pain syndrome (PFPS) that appears to support the theory that the two conditions lie on the same continuum, according to research from the University of Calgary presented in late May at the ACSM meeting.

Connecting instability and ankle osteoarthritis

Not all patients with chronic ankle in­stability develop ankle osteoarthritis, but evidence suggests the two con­ditions are related, which in turn sug­gests that ankle sprain prevention and management could help reduce ankle replacement rates.

FUTURE SHOCK: Youth sports and osteoarthritis risk

There’s no question that exercise is good for kids. But the trauma asso­ciated with some youth sports can dramatically increase the risk that those kids will develop knee or ankle oste­oarthritis by the time they reach adult­hood. The key next step is to determine what can be done about it.

Plantar loads influence knee osteoarthritis risk

Research suggests that redirecting ground reaction forces relative to the knee joint’s rotational center can be achieved by repositioning the foot through a number of different mechanisms.

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

Eponymous brace remains mainstay of evolving company

In 1996, after 15 years of sports podiatry practice, Douglas Richie, DPM, was frustrated by the ongoing challenge of fitting sport ankle braces to patients who also wore custom foot orthoses. The two products should have worked naturally together, but, because neither was made with the other in mind, the result was often ungainly and uncomfortable. Continue reading

Brace demand grows while market for knee arthroplasty remains static

With only 10.5% of US patients with knee osteoarthritis opting for surgery in 2013, a percentage that has not increased in 10 years, medical device manufacturers are working to meet the clear demand for solutions that delay unwanted surgery, according to a November report from London, UK-based GlobalData.

Sensory-targeted ankle rehabilitation strategies

Current treatments for chronic ankle instability (CAI) may be ineffective in reducing its development and recurrence. To help address this issue, the authors have proposed a new treatment paradigm based on …

Effects of unstable shoes: Many questions remain

Current research suggests that relatively small but statistically significant changes are associated in the short term with the use of unstable shoes. However, it is unclear if those changes are clinically meaningful, or whether long-term use would yield greater or diminished results.

Offloading the diabetic foot: Effects of obesity

Increasing body mass index is associated with significantly increased peak plantar pressures regardless of the type of off­loading device used. However, it is possible to decrease plantar pressures in some regions of the foot with the use of offloading devices.
