Objective: The study aimed to investigate the polymorphism of fibrillin-2 (FBN2) and elastin genes in patients with Achilles tendon rupture and to compare the results with a control group of participants who did not experience such an injury.
Methods: In this prospective study, 106 consecutive patients in whom traumatic Achilles tendon rupture was diagnosed and treated were included. The control group consisted of randomly selected 92 athletes (10 women and 82 men) 85 of whom had practiced sports in the past, aged 40-76 years, who during their sports career did not experience Achilles tendon ruptures. Material for genetic tests was obtained by the swab from the oral cavity epithelium of all the study population.
Results: 102 (96%) of patients with traumatic Achilles tendon ruptures were people with polymorphism B or heterozygotes for the elastin gene. 97 (92%) of patients with traumatic Achilles tendon ruptures were people with polymorphism B and heterozygotes for the FBN2 gene. Patients with homozygote A of the elastin gene and homozygote A of the FBN2 gene demonstrated a considerably lower incidence rate of sport-related Achilles tendon rupture. The type of sport that led to the Achilles tendon rupture and the amount of experience practicing it, as well as BMI and drug usage, did not contribute to a higher rate of incidence of any additional musculoskeletal problems or a longer time to return to their pre-injury sports activity. Polymorphisms of the fibrillin 2 (P=.0001) and elastin (P=.0009) genes impact the occurrence of traumatic injury to the Achilles tendon. However, it does not affect the length of full recovery time (P =.2251).
Conclusion: Minimally invasive and, above all, safe collection of genetic material from the epithelium of the oral cavity in order to assess the polymorphic state of the FBN and elastin genes may allow the identification of a group of players at risk of Achilles tendon rupture resulting in long-term injury, which will significantly affect their sports career in the future.

Minimum 24-Month Outcomes of Minimally Invasive Paratenon Protection Repair vs Open Giftbox Repair of Ruptured Achilles Tendon.

Background: The paratenon has been shown to promote Achilles tendon healing, but the evidence supporting the role of paratenon protection technique in Achilles tendon repair is sparse. We retrospectively assessed the results of a paratenon-sparing repair technique vs an open giftbox repair of Achilles tendon ruptures.
Methods: Patients with Achilles tendon rupture who underwent surgical treatment at our hospital between January 2015 and August 2021 were retrospectively reviewed.

Obesity is one of the most common chronic diseases seen in children and adolescents. This study aims to examine the impact of obesity on body composition, assessed by sonographic and anthropometric measurements, and health-related quality of life (HRQoL) in adolescents.Anthropometric measurements, sonographic measurements of subcutaneous fat, quadriceps muscle, Achilles tendon thickness, and HRQoL were performed in children between 12-18 years of age.

Achilles tendinopathy (AT) is the most common running-related pathology among masters runners. Previous evidence suggests there are no differences in submaximal running biomechanics between masters runners with and without AT. Evidence suggests lower extremity power deficits are common among ageing individuals and those with AT.

Lower limb biomechanics of chronic ankle instability (CAI) individuals has been widely investigated, but few have evaluated the internal foot mechanics in CAI. This study evaluated bone and soft tissue stress in CAI contrasted with copers and non-injured participants during a cutting task. Integrating scanned 3D foot shapes and free-form deformation, sixty-six personalized finite element foot models were developed.

Purpose: Achilles tendinopathy (AT) is associated with altered tendon's morphological and mechanical properties, yet it is unclear whether these properties are reversed upon mechanical loading to promote tendon healing. This study aims to determine the extent to which pathological tendon's morphological and mechanical properties adapt throughout a 12-week eccentric rehabilitation protocol.
Methods: Forty participants with midportion AT were recruited and participated in a 12-week eccentric rehabilitation program.
