A Comparative Study on Angular Compartment of Hip Flexion Before and After Training: A Case of 11 to 12-Year-old Soccer Players | Chapter 13 | Issues and Developments in Medicine and Medical Research Vol. 8

 An anterior cruciate ligament (ACL) injury is a common reason for athletes to take time off. This injury is most commonly sustained when participating in sports, and it occurs more frequently during competition than during training. ACL injuries are most often caused by biomechanical risk factors that increase ACL tension and do not require external impact. The increase of the hip flexion angle (HF) is one of them. Because the ACL relies on the collaboration of the periarticular musculature of the knee, muscle groups, hip stabilisers, and CORE muscles, tiredness produced by exercise would throw off the balance and jeopardise the ligament.

The goal of the study is to investigate the angular behaviour of HF in children aged 11 to 12 years old before and after a physical load (a standardised training).

A non-randomized clinical trial was conducted. A total of 50 soccer school children aged 11 to 12 years old were included in the study. Before and after a training session, the angular behaviour of HF was compared. The angular behaviour was assessed using data from inertial sensors and the Drop Jump test (DJ).

There was a considerable increase in HF after the workout. It was found that following training, the angular behaviour of HF increases markedly in both extremities, and that preventive measures for neuromuscular control of the hip must be taken.

Prevention Programs: Hip Angle Behaviour in Landing after Drop Jump in Children | Chapter 14 | Issues and Developments in Medicine and Medical Research Vol. 7

 Background: Although the anterior cruciate ligament (ACL) damage is uncommon, it accounts for a significant percentage of sports-related injuries needing more than 8 weeks of recuperation. Most ACL injuries are caused by biomechanical risk factors such as increased knee valgus angle (KV) and hip flexion (HF) and decreased knee flexion (KF). The ACL relies on muscular cooperation to resist the stress; however, as the musculature becomes fatigued, its protective capacity decreases.The study's goal is to examine the angular behaviour of children aged 14-15 years old before and after a physical load for HF.Hypothesis: A single training session's physical stress is sufficient to alter some biomechanical risk variables for ACL damage.The study was designed as an experiment.Evidence Level: 2b.The sample consisted of 50 students aged 14 to 15 years old from various soccer schools. Before and after a training session, we looked at the hip angular behaviour of hip flexion. The angles were measured using an inertial sensor as the students did a Drop Jump test from a 30 cm drawer.

Results: The differences between pre physical load HF / post-load HF (p = 0.00053), right prior physical load HF / right post-load HF (p = 0.0086), and left post-load (p = 0.0248206) were statistically significant.

Conclusions: After completing a physical load, the angular behaviour of HF increases significantly in both post-training limbs.

Clinical Importance: This study looked at the importance of implementing injury prevention programmes from the start, emphasising the eccentric role of hamstring, gluteus, and core movements.

Study on MRI Spectrum of ACL Tears in Pediatric Age Group: A Case Series | Chapter 12 | New Frontiers in Medicine and Medical Research Vol. 15

Anterior cruciate ligament (ACL) injuries are common among adolescents due to their high participation in outdoor activities. Knee ligament tears are almost always accompanied by other injuries. We demonstrated a variety of injuries seen in the paediatric teenage population. Routine radiography misses a variety of knee problems, such as meniscal rips and bone marrow oedema. In the creation of this spectrum, magnetic resonance imaging (MRI) is crucial.

Methods: Five male patients, ages 13 to 18 (average age 15), with diverse types of knee damage underwent knee MRI scans and were examined for a range of ACL rupture and associated symptoms. A specific injury could involve the ACL, the menisco-femoral link, or the medial collateral ligaments. Because of their undeveloped skeletons, children are also prone to bony avulsion fractures. The study plays an important part in management, according to the description of the individual injury. Patients with a history of knee injury or disease were not allowed to participate in the trial.

The bulk of the patients belonged to the paediatric teen age group (average age 15 years). The left knee was damaged 60% of the time, while the right knee was hurt 40% of the time. Meniscal tears were found in 20% of instances, but were seen in 40% of those who had a bone injury. The only way to detect these was through an MRI study, as the plain skiagram was normal. The posterior cruciate ligament (PCL) was implicated in 40% of the cases.

Conclusion: ACL tears and concomitant injuries in children and adolescents have a different spectrum and should not be diagnosed or treated the same way they are in adults. Because of the prevalence of epiphyseal nonunion in this age group, MRI evaluation is essential in the diagnosis of such severe injuries.
