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

Biomarkers suggest link between OA, stiff landing after ACL reconstruction

Knee stiffness during landing in patients who have had anterior cruciate ligament (ACL) reconstruction is associated with biomarkers for cartilage degeneration, suggesting that a stiff landing technique may increase the risk of knee osteoarthritis…

Cost-benefit data support reconstruction of ACL tears

In both the short term and the long term, anterior cruciate ligament reconstruction produced greater quality of life improvements at a lower cost compared with rehabilitation only, suggesting that limiting access to ACL reconstruction may be harmful to patients and costly to society.

Effects of targeted exercise on chronic ankle instability

Clinicians and researchers are increasingly utilizing exercise protocols focused on improving proprioception, range of motion, and strength to influence the more active and functional deficits that have been associated with chronic ankle instability in the literature.

Cell games: Clinical use of stem cell therapy is starting to outpace the evidence

Stem cell therapy is rapidly gaining momentum as a clinical option for indi­ca­tions including meniscal injury, wound healing, and osteoarthritis. But high-level research on the tech­nol­ogy’s efficacy and long-term safe­ty is hard to come by.

Vitamin D and knee OA: Many theories, few answers

Several patient populations with an increased risk of knee osteoarthritis also are at increased risk for vitamin D deficiency, and research suggests vitamin D levels may be related to knee OA symptoms. The exact nature of the relationship, however, remains perplexing.

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.
