Biomechanics

In patients with unilateral hip osteoarthritis (OA)—where the risk of progressive symptomatic OA developing in contralateral knees is higher than in ipsilateral knees—loading and structural asymmetries appear early in the disease course, while the knees are still asymptomatic.

Patients who receive walking skills training after total hip arthroplasty for osteoarthritis show improved physical function.

Ankle injuries rank among the most common musculoskeletal complaints, often sending patients to an emergency department or primary care physician's office. Here you learn the most important causes and how to treat them.

Familiarity with metatarsalgia, an array of disorders that cause pain to the forefoot, enhances the clinician's ability to make the proper diagnosis.

Walking at a slow speed up a moderate incline is an alternative exercise strategy for obese adults that may reduce the risk of musculoskeletal injury and pathological disease associated with brisk, level walking and provide proper cardiovascular stimulus for weight management.

Quadriceps muscle strains occur frequently in athletes, and the rectus femoris is the most frequently injured quadriceps muscle. The mechanism of injury typically involves an eccentric contraction during kicking or sprinting. Quadriceps strains may occur at the proximal and distal musculotendinous junctions.

The first detailed comparison of thoracic vertebrae between humans and other primates shows that humans are set up by nature to have vertebral fractures.

The incidence of ankle fractures in the older patient population is rising. These fractures are characterized as fragility fractures associated with osteoporosis, but propensity for falls, increased weight, and polypharmacy may be bigger risk factors than poor bone quality.

Patients who follow a home exercise program after a hip fracture are more likely to remain active than those who receive usual care.

A multidisciplinary team at the UC Davis Health System is conducting experiments to confirm the relationship between osteoarthritis (OA) and Maf factors

Gait speed, known to be associated with survival in older adults, may be a simple and accessible indicator of health in these patients.

Greater levels of physical activity are significantly associated with higher functional performance objectively measured by gait speed in adults with confirmed radiographic knee osteoarthritis (OA). There is a consistent graded relationship between physical activity level and better performance in these patients.

Many overuse injuries associated with running, such as tendinitis, shin splints, and stress fractures, can be prevented.

The researchers used animal models with torn ACLs to test 3 types of fluids that could be injected into the joints to serve as a substitute for lost synovial fluid: human synoviocyte lubricin that was created in a culture and then purified to be

Physicians who treat athletes with traumatic foot and ankle injuries should know when to order special imaging studies, determine whether injuries can be managed in the office or require referral, and return the athlete to sports activity quickly. For simple ankle sprains, plain x-ray films usually are not indicated; functional rehabilitation is a first-line treatment.

Synovial inflammation in osteoarthritis (OA) is secondary to mechanical damage to the articular cartilage and bone. OA often is said to be a disease of weight-bearing joints, but it is more appropriate to consider them as load-bearing joints. OA is the failure of an organ, the synovial joint.

Hip injuries are common in dancers, runners, and soccer players. Knowledge of the mechanism of injury and the sport can help uncover the diagnosis. Muscular strength testing should be performed on the cardinal movements of the hip joint.

Martial arts fall training may reduce the risk of hip fractures in persons with osteoporosis. Training is safe if they wear hip protectors that could attenuate the maximum hip impact force by at least 65%, perform the fall exercises on a thick mattress, and avoid forward fall exercises from a standing position.

The risk of symptom progression for asymptomatic rotator cuff tears after a short-term follow-up interval is substantial.
