Introduction: Question of femoroacetabular impingement is very actual. This young concept brings mechanism which leads to early degenerative changes of the hip joint of young and active individuals (athletes). Objectives: To review influence of sport activity on condition of the hip joint of young athletes (players of table tennis) and to determine incidence of femoroacetabular impingement and its clinical significance. Methods: We performed ultrasound and clinical examination and questionnaire with 22 individuals from 2 training groups. Groups vary in age, height, weight, volume of sport activity and how long they do sports. We found out incidence of cam-type impingement and evaluated pain of anterior impingement test, ranges of motions of the hip joint and deep squat. Results: Cam impingement was found in 27 hip joints, 16 in older group, 11 in younger one. In older group there were 12 from 16 impingements painful during anterior impingement test, 4 from 11 in younger one. In older group there were 4 symptomatic individuals, none in younger one. Older group has lower ranges of motion of flexion and internal rotation. 4 individuals did not perform deep squat, all of them with bilateral cam-type impingement. Conclusion: Femoracetabular impingement is frequent among young athletes. It causes...

This systematic review investigates the biomechanical risk factors associated with femoroacetabular impingement (FAI) in female athletes. Using a particular methodology, the review synthesizes relevant sources to comprehensively analyze multi-factorial contributions to FAI, including load distribution, forces, strain, and sport-related mechanisms. By critically evaluating existing literature, this study aimed to provide a nuanced understanding of the intricate biomechanical aspects influencing the development of FAI in female athletes. A thorough examination of the literature encompassed articles spanning the years 2000 to 2024. Intentional sampling techniques were employed to guarantee the inclusion of female athletes across a diverse array of sports disciplines, including but not limited to soccer, ice hockey, running, and competitive dance. This approach aimed to provide a holistic view of biomechanical factors across different athletic activities. Data extraction systematically collected information from the selected studies, including study characteristics, participant profiles, methodology, and relevant outcomes pertaining to biomechanical factors linked to FAI in female athletes. A comprehensive literature review was performed, and articles that met the inclusion criteria were identified. The Downs and Black tool was subsequently used to evaluate the methodological quality of each study, recognizing the importance of considering factors such as reporting clarity, external validity, bias, confounding, and statistical power. Common themes were synthesized, and it was found that specific biomechanical factors, such as hip joint mechanics during dynamic movements and abnormal loading patterns, played significant roles in the development and progression of FAI in female athletes.
