This study provides the first insights into fast and slow muscle fiber transcriptome dynamics with lifelong endurance exercise. The fast fibers were more responsive to exercise with divergent transcriptome signatures among young exercisers (growth and metabolic), lifelong exercisers (metabolic), and old healthy nonexercisers (stress).
Investigators from Shaanxi Normal University in China studied the impact of increasing backpack load on the gait of adolescents during stair descent. Sixteen healthy male students (age = 12.9 ± 0.6 years) were required to descend the stairs in 4 loaded conditions. The kinematic, kinetic, and EMG data were collected synchronously and gait parameters, especially indicators of balance control, were analyzed.
Ankle osteoarthritis severely impacts patients’ mental and physical quality of life. Besides total ankle replacement and ankle arthrodesis, ankle distraction has been shown to be a promising alternative. The primary aim of this systematic literature review and meta-analysis was to determine the annual revision rates (ARRs) after ankle distraction.
Competitive athletes are always looking for an extra edge to help improve performance. According to a new study by Concordia researchers published in the journal Physical Activity and Nutrition, they can find one in the common cranberry.

Researchers from the Department of Orthopaedics at the Nemours Children’s Hospital Delaware (Wilmington, DE) wanted to understand the change in dynamic foot posture in children with cerebral palsy. They were able to track 33 children (54 limbs) who completed 16.9 evaluations from an initial age of 2.9 (±0.7) yrs to 18.6 (±1.7) yrs. They found that early valgus foot…
With the growing popularity of large language model (LLM) chatbots, a type of artificial intelligence (AI) used by ChatGPT, Google Bard ,and BingAI, it is important to outline the accuracy of musculoskeletal health information they provide. Three new studies presented at the 2024 Annual Meeting of the American Academy of Orthopaedic Surgeons ( AAOS ) analyzed the validity of the information chatbots gave…
As the use of robotic assistance in total knee arthroplasty (TKA) has grown, there has been limited research looking at whether it improved the risk of revision. New data showed that revision rates were similar in conventional and robotic-assisted cementless TKA at 2 years post-operatively. Presented at the 2024 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS), the study…
According to new data presented at the 2024 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS), sports injuries in seniors have increased significantly from 55,684 in 2012 to 93,221 in 2021 in the United States with significant differences in the types of activities and injuries.

In adolescent athletes who underwent anterior cruciate ligament reconstruction (ACLR), the younger the athlete at the time of primary ACLR and an earlier return to sport (RTS) were significantly associated with an increased rate of secondary ACL injuries, according to a new study presented at the 2024 Annual Meeting of the American Academy of Orthopaedic Surgeons…
Chronic conditions such as diabetes and peripheral vascular disease were the leading cause of amputation for more than 60% of patients treated at Indiana University Center for Limb Loss (CLL), a Level 1 Trauma Center, according to a new retrospective study. In looking at the electronic medical records of 218 amputee patients who…
The US Amputee Football Federation (USAFF) provides participants with an environment and opportunity to regain hope that may have been lost after amputation.
