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

High heels: Elevating the discussion

The biomechanical implications of high-heeled shoes are well known, and now dramatic weight-bearing images and new study findings are taking practitioner and patient awareness to the next level. But many women are still sacrificing their feet for fashion.

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.

Functional contributors to outcomes after TKA

The increasing utilization of total knee arthroplasty has led to increased efforts to identify variables that can be modified to help improve postoperative functional outcomes. These risk factors include patient weight, smoking, diabetes, infection, and joint range of motion.

Vibration intervention helps counteract induced arthrogenic muscle inhibition

Both direct local muscle vibration (LMV) and whole body vibration (WBV) improve quadriceps arthrogenic muscle inhibition (AMI), according to a study from neuromuscular researchers at the University of North Carolina at Chapel Hill. The findings suggest vibratory stimuli can enhance …

Internal vs external focus: Effects on motor learning

A growing body of research is demonstrating that the focus of actions or movements is critical to how well athletes and patients respond to feedback from instructors or clinicians, and one of the central issues is the distinction between internal focus and external focus.

Knee OA, BMI, and pain: A complex relationship

Excess body weight is considered by many experts to be the primary modifiable etiological factor in knee osteo­arthritis (OA) development. However, the relationship among body mass index (BMI), the anatomical manifestations of knee OA, and knee pain is not clear-cut.

Incline walking: An offloading option for patients with knee OA

Incline walking on a treadmill results in less frontal plane knee loading and more gluteus, hamstrings, quadriceps, and triceps surae muscle activation than level walking, and therefore may benefit patients with knee osteoarthritis or those who have undergone knee replacement.

Flexible flatfoot: Foot orthoses and outcomes

Many studies have shown an effect of foot orthoses on biomechanical function in patients with flexible flatfoot, but few studies have focused on patient-centered outcomes. There is a need to investigate the effect of foot orthoses on pain and fatigue in these individuals over time.

Outcome studies continue to support Ponseti method

Clubfoot researchers have begun to report long-term data that continue to solidify the superiority of the conservative method over surgical intervention in most cases. But variations to the traditional Ponseti method are arising, particularly in developing countries, and may alter outcomes.
