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.

OSTEOARTHRITIS: Knee braces and wedged insoles both alter gait in patients with knee OA

A Taiwanese study offers more evidence that offloading knee braces and wedged foot orthoses are both associated with significant biomechanical improvements in patients with knee osteoarthritis (OA).

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

Bariatric surgery: Effects on patient gait and function

Existing data suggest bariatric surgery-induced weight loss can lead to rapid improvements in gait and physical function. The surgery may also help to address factors associated with knee osteoarthritis, which itself can affect mobility and function in obese patients.

Ponseti method surpasses surgery for long-term clubfoot outcomes

But both groups fall short of controls - Children treated for clubfoot with the Ponseti method have less pain and fewer gait impairments as adults than those treated with surgery, according to research from Shriners Hospital for Children in Chicago.

TKA in obese patients: Weighing the risks vs the benefits

Total knee arthroplasty significantly improves functional outcomes in obese patients, but is also riskier than in normal-weight patients. As the number of obese patients with knee osteoarthritis continues to rise, clinicians are being challenged to find a balance between the risks and the benefits.

Exploring treatment options for intermittent claudication

Despite the documented benefits of supervised exercise in patients with claudication, its effect on actual clinical practice has been disappointing due to a lack of reimbursement. But practitioners and research­ers have been investigating other options, with encouraging preliminary results.

Knee injury prevention: Hip and ankle strategies

Many knee injury prevention programs do not focus on ankle dorsiflexion range of motion and hip adductor activation, but research suggests both distal and proximal variables contribute to alterations in frontal plane knee biomechanics and could affect injury risk.

Painful hip impingement: Functional implications

Physical impairments associated with femoroacetabular impingement include limited range of motion, muscle weakness, and altered biomechanics. Attention to these areas during rehabilitation can improve surgical outcomes and may even reduce the risk of osteoarthritis.

Richie Brace: 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.

Energetics of landing: Effects of ankle instability

A diminished capability for energy dissipation at the knee after ground impact during landing in patients with chronic ankle instability may result in greater demands on the ankle joint. Modifying landing strategies could potentially reduce the risk of musculoskeletal injury.
