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

Footwear and risk of knee OA: The search for meaning in moments

Although footwear may in fact play a role in the development of knee osteoarthritis and its clinical management, those relation­ships are turning out to be much more complicated than once thought.

Total ankle arthroplasty: defining its clinical niche

Research generally upholds total ankle arthroplasty as a viable alternative to the traditional first-line surgical treatment, ankle arthrodesis, for correctly selected patients with end-stage ankle arthritis. But complication rates associated with ankle arthroplasty remain an area of concern.

Obese children develop knee malalignment as they mature

Effect might increase future OA risk – As obese children undergo the rapid physical changes of puberty, they develop knee malalignment that could potentially contribute to development of knee osteoarthritis (OA), according to recent research from Nationwide Children’s Hospital in Columbus, OH.

Lumbar link? Ankle, spinal pathologies coexist in cadavers

Practitioners treating a patient with ankle osteoarthritis (OA) may want to ask if the patient has a history of back pain, according to a recent study that found an association between lumbar disc degeneration and ankle OA in cadavers.

Knee and hip OA significantly impact quality of life in younger adult patients

Adults aged between 20 and 55 years with hip or knee osteo­arthritis (OA) report significantly higher levels of distress and disability and poorer health-related quality of life than the general population for that age range, according to research from the University of Melbourne in Australia.

Hip disorders in children with Down syndrome

As hip arthritis becomes a growing concern in adults with Down syndrome, clinicians are also becoming more attuned to hip issues in children with DS, in hopes that early intervention in the pediatric population will help reduce the risk of disability later on.

Out on a limb: Rethinking pain

Pain doesn’t always behave the way we think it will. An intervention that relieves pain in the majority of patients might not provide relief for a significant minority. But that might mean we need to change the way we think about pain.
