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

Offloading strategies for knee osteoarthritis

Altering joint alignment is associated with decreased pain and improved function. Researchers are working to explain the mechanisms underlying these effects, particularly with respect to bracing.

Somatosensory deficits following ACL surgery

Research suggests light touch sensation in the foot and ankle may be negatively affected several years after anterior cruciate ligament (ACL) reconstruction—a finding consistent with studies that have reported decreased somatosensation in patients with other lower extremity conditions.

Rocker-bottom footwear: effects on balance, gait

Footwear with rocker soles are best known for helping to redistribute plantar pressures during gait in patients with diabetes, but research suggests they also have clinically relevant effects on balance and gait that can be beneficial for some populations but potentially dangerous for others.

Chronic ankle instability and self-reported function

Using patient-reported outcome tools can give lower extremity clinicians insight into the disability experienced by patients with chronic ankle instability. A combination of instruments may be necessary, as different assessments may capture different aspects of the condition.

Foot posture, orthoses, and patellofemoral pain

Prescription of foot orthoses for runners with patellofemoral pain (PFP) is often based on the premise that individuals with excessive pronation are among those most likely to have a positive response. However, preliminary analyses indicate this may not be the case.

Putting prehab to the test highlights inconsistencies

The growing popularity of prehabilitation contrasts with mixed findings in the lower extremity literature: Specifically, the approach seems to be more effective in patients undergoing anterior cruciate ligament (ACL) reconstruction than those undergoing hip or knee replacement.

Knee OA in amputees: Biomechanical and technological considerations

The risk of knee osteoarthritis in the intact limb of longtime unilateral amputees is much higher than in non­amputees, and the range of potential contri­buting factors is even more complex. Optimizing prosthetic fit and function, in addition to more conventional OA interventions, can help address gait issues that contri­bute to knee joint degeneration.

Out on a limb: In search of symmetry

Researchers and clinicians who work with unilateral lower limb amputees are increasingly exploring the effects of prosthetic devices on gait asymmetries and joint loading. What’s less well known is that prostheses designed for use above the waist can also have positive effects on gait.
