Knee injury prevention: Hip and ankle strategies

Many knee injury prevention programs do not focus on ankle dorsiflexion range of motion and hip adductor activation, but research suggests both distal and proximal variables contribute to alterations in frontal plane knee biomechanics and could affect injury risk.

Painful hip impingement: Functional implications

Physical impairments associated with femoroacetabular impingement include limited range of motion, muscle weakness, and altered biomechanics. Attention to these areas during rehabilitation can improve surgical outcomes and may even reduce the risk of osteoarthritis.

A proximal perspective on patellofemoral pain

Hip strengthening can improve short-term outcomes related to patel­lo­­femoral pain syndrome, but further research is needed to determine the underlying mechanism and whether the same approach will also prove effective in managing patello­femoral osteoarthritis.

Prepare for landing: Bladed cleats may put fifth met at risk

Bladed soccer cleats were associated with increased forefoot loading during a jump-landing task, which may lead to a higher risk of fifth metatarsal stress fractures, according to a study published in the September-October issue of the Journal of Athletic Training.

Energetics of landing: Effects of ankle instability

A diminished capability for energy dissipation at the knee after ground impact during landing in patients with chronic ankle instability may result in greater demands on the ankle joint. Modifying landing strategies could potentially reduce the risk of musculoskeletal injury.

Conference coverage: 3rd PFP research retreat

The third International Patellofemoral Pain Research Retreat picked up where previous retreats had left off in examining proximal and distal factors related to PFP and subgroups of patients who might respond to targeted interventions. But this retreat broke some new ground as well.

Plantar plate repair: New approach to metatarsalgia

Plantar plate pathology in conjunction with metatarsalgia occurs more often than is commonly appreciated, but can be addressed using a combined procedure that involves a dorsal approach to anatomic plantar plate repair and metatarsal realignment.

Achilles tendon rupture: The influence of gender

The literature suggests that women are less likely than men to experience an Achilles tendon rupture. This may be because women are less capable of generating the large eccentric contractions necessary for rupturing the tendon. Estrogen may also play a protective role.

Limited hip flexibility: Mutability and mobility

Myofascial or joint-focused stretches can increase passive hip range of motion in young adult men with limited hip flexibility, but this will not necessarily result in more hip motion actually being utilized during functional activity unless old movement patterns can be unlearned.

Debating the complexities of partial foot amputation

Partial foot amputations may not offer a biomechanical advantage over transtibial amputations if the metatarsal heads cannot be retained, and some experts suggest amputation level should be selected based on probability of wound healing instead. But others disagree.

Platelet-rich plasma: An option for tendinopathy

Patients with chronic refractory lower extremity tendinopathies often continue to have symptoms after exhausting most of their therapeutic options. Preliminary evidence supports the use of platelet-rich plasma in these patients, though higher-level research is needed.
