RESUMO
Purpose: The study aimed to investigate whether morphometric variables of the knee can predict isolated meniscal bucket-handle tears and identify the risk factors. Methods: The study included 146 participants with a mean age of 36.547 ± 12.279 years. They included two groups of 73 patients each: one group with isolated meniscal bucket-handle tears and another with no knee injury (control group). Magnetic resonance imaging findings of the participants were retrospectively assessed. A few morphometric variables associated with distal femur, proximal tibia, and cruciate ligaments were measured. Results: Cruciate ligament tensity (CLT), medial femoral condylar height (MFCH), and lateral meniscal bone angle (LMBA) were found to be 12.7 ± 0.3, 30.1 ± 2.5 mm, and 21.2° ± 3.4°, respectively, in patients with meniscal bucket-handle tear, compared with 11.9 ± 0.2, 28.3 ± 2.7 mm, and 26.5° ± 3.7° in the control group, respectively. Based on multivariate Firth's logistic regression analysis, CLT (Odds ratio [OR]: 456.533; 95% confidence interval [CI]: 27.582 to > 999.999), MFCH (OR: 1.603; 95% CI: 1.023-2.513), and LMBA (OR: 0.780; 95% CI: 0.624-0.975) could distinguish between meniscal bucket-handle tears and knees without meniscus tears (p < 0.05). Based on the multicategorical multinominal regression model, CLT (OR: > 999.999; 95% CI: 49.937 to > 999.999) and MFCH (OR: 1.903; 95% CI: 1.005-3.606) were the determinant variables in differentiating medial meniscal bucket-handle tears from knees without meniscus tears (p < 0.05). Conclusion: Large CLT, high medial condyle, and small LMBA were revealed as the morphometric risk factors for meniscal bucket-handle tear.
RESUMO
OBJECTIVE: This study aimed to determine the effects of cam and pincer morphology on the hamstring injury rate, treatment duration, and recurrence number of elite young male football players. METHODS: Seventy-five elite young male football players were included in this study. Participants were evaluated physically and radiologically for femoroacetabular impingement during pre-season or pre-transfer routine health examinations. Athletes' injury and treatment data for 6 seasons were then collected prospectively and evaluated retrospectively. Athletes were divided into 2 groups: patients with cam and pincer morphology (group 1) and those without (group 2). Both groups were compared regarding the number of hamstring injuries, treatment duration, and recurrence numbers. RESULTS: The mean age was 20.35 ± 1.37 in group 1 (n = 23) and 18.92 ± 1.48 in group 2 (n = 52). There was a significant difference between the 2 groups regarding age and body weight. The rate of hamstring injuries in group 1 was higher than in group 2, and this difference was statistically significant. Although the recurrence rate (group 1-35.7%, group 2-27.8%) and treatment duration (group 1: 18.4 ± 10.1 days, group 2: 12.1 ± 6.2) in group 1 were higher than in group 2, there was no statistical significance between 2 groups. CONCLUSION: The present study has shown that hamstring injuries are more common in elite young male football players with cam and pincer morphology than those without. Therefore, further studies of musculoskeletal dysfunctions of femoroacetabular origin should be considered in the programs prepared to prevent and treat hamstring injuries. LEVEL OF EVIDENCE: Level III, Prognostic Study.

BACKGROUND AND OBJECTIVE: YouTube has become a digital visual library in almost all fields of life, including medicine. Healthcare professionals and students frequently use YouTube to gain new skills and knowledge; however, the content of these videos has not been scientifically evaluated. Therefore, this study aimed to determine the descriptive adequacy and quality of YouTube videos on lumbar spine manipulation techniques (LSMTs) prepared by different healthcare professionals. METHODS: The first 50 most relevant videos retrieved on searching YouTube for the keyword 'lumbar spinal manipulation techniques' were included in the study. The video metrics (total duration, number of views, time since upload, number of comments, number of likes, and number of dislikes) that could be accessed from video descriptions were recorded. However the videos were scored according to manipulation definition criteria proposed by the American Academy of Orthopedic Manual Physical Therapists (AAOMPT manipulation description score - AAOMPT-MDS) and benchmark criteria for quality of digital content by the Journal of American Medical Association's (JAMA). The video metrics, AAOMPT-MDS and JAMA scores of the videos prepared by medical doctors, chiropractors, osteopaths, and physiotherapists were compared. RESULTS: Video metrics of groups were similar. The mean AAOMPT-MDS of the videos was 2.40 ± 1.57 out of 6.00 (higher score was better), and the mean JAMA score was 2.14 ± 1.05 out of 4.00 (higher score was better). Videos created by all professional groups had statistically comparable AAOMPT-MDS and JAMA scores (p > 0.05). CONCLUSION: Although YouTube videos on LSMTs offer valuable information for professionals and students, creators should follow the proposed recommendations when producing these videos to ensure quality content and systematic presentation.

BACKGROUND: The Functional Movement Screen (FMS) is a clinical assessment tool used to determine musculoskeletal dysfunctions and asymmetries in athletes. OBJECTIVE: The aim of this study was to investigate whether FMS scores differed between elite youth male soccer players with low body fat percentage and those with normal body fat percentage and between those with and without a history of soccer injury. METHODS: Fifty-three elite youth male soccer players were included in the study. The participants' injury histories were recorded, followed by body composition assessment and FMS tests. The participants were grouped according to body fat percentage and injury history for data analysis. RESULTS: The mean age, weight and height of the participants were 17.11 ± 0.91 years, 68.78 ± 7.41 kg and 1.77 ± 0.57 meters, respectively. Comparisons of the groups according to body fat percentage and injury history revealed no differences in FMS scores (p> 0.05). CONCLUSION: Lower body fat percentage did not confer an advantage or disadvantage to elite youth male soccer players in terms of FMS scores FMS scores provide limited information to predict injuries in elite youth male players.

Postaxial hypoplasia of the lower extremity, formerly termed as fibular hemimelia, is characterized by lower limb length discrepancy and a broad spectrum of anomalies involving the ipsilateral limb. It is a rare skeletal abnormality with an incidence of 5.7-20 cases per 1 million births. Herein, we present a young man with postaxial hypoplasia of the lower extremity who admitted to the hospital for a reason other than musculoskeletal complaints. While his limb length discrepancy was rather mild, the accompanying tarsal coalition was of an extensive form involving talus, calcaneus, navicular, and cuboid. Such extensive fusions of the hindfoot are very rare, and they are commonly associated with congenital syndromes such as postaxial hypoplasia of the lower extremity and Alpert syndrome. Therefore, further investigation for accompanying abnormalities is needed in cases with extensive fusions of the hindfoot.
RESUMO
PURPOSE:: The aim of this study was to determine the prevalence of asymptomatic radiographic findings of femoroacetabular impingement (FAI) in paediatric football players in different age groups and to investigate aetiological factors. METHODS:: Paediatric male athletes between 10 and 17 years of age from 8 soccer teams were recruited. In addition to an annual control check-up, anteroposterior pelvis and frog-leg radiographs as well as the curriculum vitae of the athletes, their injuries, and real-time complaints were recorded. The alpha angle, lateral centre-edge angle, Tönnis angle, and collodiaphyseal angle were measured and morphological abnormalities were noted. RESULTS:: There were 214 male football players with a mean age of 13.4 ± 3.2 years included in the study. In the morphological analysis of hips, there was FAI in 30% of the athletes. In the analysis of FAI prevalence in 3 subgroups based on age (Group 1: 10-12 years [ n = 25], Group 2: 13-15 years [ n = 104], Group 3: 16-17 years [ n = 85]), there was 0% FAI in Group 1, 19.1% in Group 2 and 60% in Group 3. In the analysis of aetiological factors, there was no significant difference between the right and left hips of players regarding alpha angles and FAI prevalence. However, the prevalence of FAI was higher in players who had been playing football for 3 years or more and who had been training for 12.5 hours/week or more. CONCLUSION:: Training for 12.5 hours or more per week in paediatric football players doubled the risk development of FAI morphology.

To increase movement capacity and to reduce injury risk in young soccer players by implementing a special functional exercise program based on functional movement screen (FMS) and correctives. 67 young male athletes 14-19 years of age from a Super League Football Club Academy participated in the study. Functional movement patterns were evaluated with FMS assessment protocol. Deep squat, hurdle step, inline lunge, shoulder mobility, active straight leg raise, trunk stability push-up, and rotatory stability were examined in FMS. Considering the FMS scores the number of intervention and control groups were defined as 24 and 43, respectively. Intervention program was composed of 1 hr twice a week sessions in total of 12 weeks with 4 weeks of mobility, 4 weeks of stability, and 4 weeks of integration exercises. At the end of 12-week intervention and control groups were re-evaluated with FMS protocol. Contact and noncontact sports injuries recorded during one season. In intervention group there was statistically significant difference in increase in total FMS scores (P<0.01), deep squat (P≤0.001), hurdle step (P<0.05), inline lunge (P<0.01), and trunk stability push-up (P<0.01). In control group total FMS, deep squat, and trunk stability push-up scores increased with a statistical difference (P<0.01, P<0.05, P≤0.01, respectively). The incidence of noncontact injury in control group was higher than intervention group (P<0.05). Periodic movement screening and proper corrections with functional training is valuable in order to create better movement capacity to build better physical performance and more effective injury prevention.
RESUMO
In this study, we explained the effects of compression garment and electrostimulation on athletes' recovery period by evaluating blood lactate and isokinetic peak torque parameters. Twenty volunteers (15.55± 0.51 yr) were included to study. At recovery period, blood samples was taken for lactate values at 0th, 3rd, 5th, 15th, 30th min. The isokinetic strength test was performed on right ankle at 15th min and on the left ankle at 30th min. The same protocol was performed for compression garment on 2 weeks and for electrostimulation on third weeks and results were compared. There wasn't any significant difference on blood lactate levels within groups. At women; there was not any significant difference on isokinetic peak torques within two groups. but at electro-stimulation usage we found significant increases on right plantar flexion (P<0.1), right dorsal flexion (RDF) (P<0.1) and left plantar flexion (LPF) (P<0.1) values compared to control measurements. At men; with compression garment usage, there was significant increase on LPF values compared to control measurements. At electrostimulation usage, we found significant increases on RDF (P<0.1) and left dorsal flexion (P<0.1) values compared to control measurements. During recovery, there is not any beneficial effect seen on blood lactate level within two groups. When compared to passive rest, compression garments and electrostimulation interventions effects on force generation capacity at recovery are statically significant. Also in terms of force generation capacity; usage of electrostimulation during 15 min and compression garments during 30 min were statically more significant.
