Barefoot running with nonrearfoot strike pattern may put Achilles at risk

Women who run barefoot with a midfoot or forefoot strike pattern have higher Achilles tendon (AT) loads—and, potentially, a higher risk of tendinopathy—than rearfoot strikers, according to research e-published May 3 in the Annals of Biomedical Engineering.

Study links concussion to increased incidence of lower extremity injury

College athletes who sustain a concussion are almost four times as likely as their counterparts who avoid the brain injury to subsequently injure lower extremity muscles, according to research presented at the 2013 American Medical Society for Sports Medicine conference held in April in San Diego.

Benefits of bracing: Studies find improvement in pain, gait

Studies presented at the 2013 World Congress on Osteoarthritis, held in April in Philadelphia, provide more evidence that knee bracing can improve pain and gait mechanics in patients with knee osteo­arthritis (OA)—improvements that are magnified with increased wear time.

Nonoperated knee remains vulnerable after unilateral total joint arthroplasty

Unilateral total knee arthroplasty (TKA) does not reduce loading in the nonoperated knee, and the resulting asymmetry may help explain why many patients end up undergoing TKA in the contralateral knee within 10 years of the initial procedure, according to an Israeli study presented at the 2013 World Congress on Osteoarthritis.

Medial meniscal damage corresponds to decreased proprioceptive accuracy

Severity of meniscal abnormality in patients with knee OA is significantly associated with severity of proprioceptive impairment, according to research from the Netherlands presented at the 2013 World Congress on Osteoarthritis.

Adding exercise to diet improves pain, function in overweight knee OA patients

Adding exercise to a dietary program does not significantly increase weight loss or reduce loading in overweight patients with knee osteoarthritis (OA) compared to diet alone, but the addition of exercise is associated with significant improvements in pain and function, according to preliminary results of a large 18-month trial presented in April at the 2013 World Congress on Osteoarthritis.

BMI and TKA: Obese patients do benefit from surgery

Reluctance to perform total knee arthroplasty (TKA) in obese patients may be unwarranted, at least when it comes to functional outcomes, according to multiple studies presented in March at the annual meeting of the American Academy of Orthopaedic Surgeons (AAOS).

Improvement in knee OA symptoms persists two years after PRP injection

Platelet rich plasma (PRP) injection in patients with mild to moderate knee osteoarthritis is associated with significant improvement in pain and function, according to research from Milan, Italy, presented in March at the AAOS meeting.

Postoperative femoral nerve blocks sap quadriceps strength, increase risk of falls

Femoral nerve blocks significantly impair quadriceps strength when used for postoperative analgesia after total knee arthroplasty (TKA) and anterior cruciate ligament (ACL) reconstruction, according to separate studies presented in March at the annual meeting of the American Academy of Orthopaedic Surgeons (AAOS).

Replacement revisited: Positive outcomes include younger patients

Total ankle replacement (TAR) is growing in popularity, as an increasing number of studies suggest that the procedure’s outcomes rival those of ankle fusion—perhaps even in patients previously thought to be poor candidates for TAR.

As in football, Achilles rupture means end of career for many NBA athletes

Fewer than half of National Basketball Association (NBA) players who suffer a complete Achilles tendon tear return to play for more than one season, and 39% never return to play at all, according to research presented in March at the AAOS meeting.

AFOs affect plantar flexion strength in some high-level volleyball players

Volleyball players without ankle instability who wear hinged stirrup ankle foot orthoses (AFOs) may experience decreased plantar flexion strength as a result, according to research from Loyola University in Maywood, IL.

Bad breaks: Fifth met fractures can curtail NFL careers

Jones and proximal diaphyseal fifth meta­tarsal fractures are common among football players and may shorten their athletic careers, according to a February study that found players with fractures were significantly more likely than players without the injuries to have played in fewer than 10 National Football League (NFL) games.

Even gradual transition to minimalist running leads to signs of stress in feet

Investigators at Brigham Young University in Provo, UT, reported that runners who transitioned from traditional running shoes to zero-drop shoes meant to mimic barefoot running had evidence of bone marrow edema, a marker for stress on the foot, after gradual transition from conventional to minimalist shoes.

Fear factors: ACL-reinjury concerns sideline athletes

A lack of confidence and fear of reinjury after anterior cruciate ligament (ACL) reconstruction is keeping some athletes from returning to play, according to several abstracts presented last month at the American Physical Therapy Association’s 2013 Combined Sections Meeting (CSM) in San Diego.

Study confirms neuromotor alterations in runners with Achilles tendinopathy

A recent study done at the University of Melbourne in Australia supports the theory that, in runners with Achilles tendinopathy (AT), altered neuromotor recruitment patterns of the triceps surae create differential intratendinous loads that lead to pathology.

Soccer simulation data show benefits of ankle supports change over time

Ankle bracing and taping have a limited ability to restrict ankle range of motion (ROM) and improve proprioceptive capability under soccer-specific conditions, according to a small study e-published by the Journal of Sport Rehabilitation in January.

Off balance: Instant total contact casts create instability

Instant total contact casts (iTCCs), which add length and weight to the involved leg, perturb balance in healthy individuals and could increase fall risks in the already–balanced challenged population of individuals with diabetic peripheral neuropathy.

Ulcer location influences healing times, from shortest at toes to longest at heel

A study e-published February 7 by Diabetes/Metabolism Research and Reviews found that time to diabetic foot ulcer healing was dependent on location, increasing progressively from toe to midfoot to heel, but did not differ between plantar and nonplantar ulcers.
