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.

Ankle instability patients exhibit landing kinematics suggestive of ACL injury risk

Sagittal plane landing kinematics in patients with chronic ankle instability (CAI) mimic those associated with risk of anterior cruciate ligament (ACL) injury, sug­gest­ing that similar neuromuscular control deficits may be involved in both processes, according to research from the University of Toledo (OH) presented in late May at the ACSM meeting.

Toning shoe twist: Embattled footwear may still have benefit

The research on toning shoes presented early this month at the annual meeting of the American College of Sports Medicine in San Francisco didn’t add much support for controversial claims that the rocker-bottom footwear promotes muscle activa­tion and energy expenditure. But the presenters did point out more subtle benefits of toning shoes that manufac­turers might find are more acceptable to the Federal Trade Commission.

Balance control in occupational boots reflects shaft height more than mass

In workers wearing occupational footwear, the mass of a boot may be less important for maintaining balance than its shaft height, according to a study presented in late May at the annual ACSM meeting.

Injuries prevent runners from adapting to acute changes in midsole hardness

Injured runners do not make sagittal plane kinematic adaptations to changes in midsole hardness the way that healthy runners do, according to research from the University of Wisconsin-La Crosse (UW-L) presented in late May at the ACSM meeting.

Weight watching: Ten percent gain or loss affects symptoms

Education about weight loss—including why it’s important and how to achieve it—should be “front and center” of any clinical encounter involving patients with knee osteoarthritis (OA), said a researcher who recently published findings on the effects of weight change over time on OA-related pain and functional limitations.

Patellofemoral cartilage damage tends to be medial, even in most valgus knees

Medial cartilage damage, not lateral damage, is the more prevalent pattern of cartilage morphology in patellofemoral knee osteoarthritis in all but the most severely involved knees, according to research from Boston University School of Medicine.

ACL reconstruction delays increase risk of meniscal, chondral injuries

Research from the University of Hong Kong provides further evidence that delaying anterior cruciate ligament surgery increases the risk of meniscal injury and articular cartilage lesions, both of which are associated with increased long-term risk of knee osteoarthritis. Investigators analyzed…

Study finds no decrease in BMI after ankle surgery despite functional gains

Overweight and obese patients with end-stage ankle arthritis may think that having surgery will inspire them to lose weight, but research from the University of British Columbia suggests that in reality this doesn’t happen. Investigators retrospectively assessed 145 patients who…

Direction change: Backward running may reduce PF pain

Backward running involves lower patellofemoral joint compression forces than forward running and is a viable strategy for rehabilitation of patellofemoral pain syndrome in runners, allowing them to continue exercise without increasing these forces, according to UK research e-published in April in the Journal of Biomechanics.
