We present the case of a preventive tibial plateau flexion osteotomy in an adolescent patient who had a reduced posterior slope of the tibial plateau. The patient was asymptomatic and without instability at the time. However, magnetic resonance imaging (MRI) showed a dysmorphic posterior cruciate ligament, which was interpreted as an indication for osteotomy. This article demonstrates the surgical technique and postoperative outcome. The postoperative MRI shows a reorganization of the posterior cruciate ligament into a physiological ligament appearance.

Injury burden is a composite measure of injury incidence and mean severity; this parameter has been reported as an output measure from injury surveillance studies in rugby for over 20 years. The benefits of reporting injury burden results have, more recently, been recognised in other sports. This wider use of injury burden as an output measure from injury surveillance studies has, however, highlighted misunderstandings about how to calculate, present and interpret injury burden data. The aim of this critical review is to explain why median severity and ordinal severity scales should not be used to calculate and report injury burden results in injury surveillance studies. Equations are presented to show how injury burden results should be calculated, and graphs and tables are presented to explain the errors that are introduced when median severity and ordinal scales of severity are used instead of mean severity. This critical review is intended to highlight the correct procedures for calculating, reporting and interpreting injury burden results in order to avoid incorrect results, conclusions and injury prevention recommendations being published.

Achieving anatomic reduction, securing fixation, and ensuring adequate compression are crucial steps in the internal fixation process for traumatic osteochondral defects. A variety of fixation methodologies have been in use, e.g., metal pins, bioabsorbable screws, and glue tissue adhesives, each of them yielding different outcomes. This study presents the outcomes of utilising the concept of suture bridge fixation for traumatic femoral osteochondral injury in a 34-year-old patient. Following a three-year follow-up, the patient demonstrated a return to normal activities with complete and pain-free knee mobility. In conclusion, it can be stated that suture bridges offer an alternative approach for the fixation of osteochondral fragments in the knee attributable to traumatic injuries.

Arthrogenic muscle inhibition (AMI) presents a persistent challenge in postoperative knee rehabilitation and is often resistant to standard care. This case series examines the efficacy of Motion-Activated Neuromuscular Electrical Stimulation (mNMES) in addressing AMI refractory to rehabilitation after ACL (revision) surgery, patellar dislocation, trochleoplasty, or conservative treatment of the patellofemoral pain syndrome. Eight patients who had undergone extensive unsuccessful rehabilitation received six weeks of a novel mNMES treatment regimen. Outcome assessments included patient-reported outcome measures (PROMs) and AMI classification. Results revealed significant improvements in pain reduction, knee function, and AMI reduction. Despite study limitations, mNMES demonstrated promising outcomes and could be used as an adjunct to standard rehabilitation, offering potential for enhancing postoperative outcomes in patients refractory to conventional therapy. Further research is required to validate these findings and optimise treatment protocols.

Intramuscular tendon injuries of the thigh muscles are a relatively common and significant problem in sports medicine, particularly in high-speed sports. MRI is a valuable tool for diagnosing and evaluating the severity of these injuries. Depending on the severity and chronicity of the injury, treatment options include conservative or surgical treatment. We present the typical MRI criteria for acute and chronic injuries to the intramuscular thigh tendons and provide a detailed description of the surgical treatment and technique. Both acute and chronic lesions can be successfully treated with surgery. In rehabilitation, MRI remains a valuable tool for monitoring, but functional tests such as EMG, force plate measurements and isokinetic testing should also be included. A return to competitive sport is typically possible within approximately four months.

The trend sports kitesurfing and wakeboarding are increasingly gaining popularity. Tricks and high jumps - both in the air and over obstacles - are performed with increasing difficulty. Repeated high loads on the body, particularly when landing after a jump, can lead to overuse and acute injuries directly related to peak forces, particularly in the lower extremities.There is a lack of detailed analyses of these forces resulting from wakeboarding or kitesurfing, although such data would be relevant for the analysis of injury mechanisms and the subsequent development of prevention strategies. This study is the first of its kind in which the loads on the lower extremity during wakeboarding and kitesurfing were subjected to in-vivo measurements during various maneuvers.Six wakeboarders and 12 kitesurfers (6 with loop bindings and 6 with fixed bindings) were investigated (mean age 33.1 ± 9.9 years). Jump height, hang time, acceleration, and the maximum vertical ground reaction force of both feet during takeoff and landing were recorded by means of sensor insoles (Moticon, Germany) on the feet of the athletes and simultaneously by a height and acceleration sensor (PIQ Sport Intelligence) on the board. A statistical analysis was performed.The data showed that wakeboarders were exposed to higher loads than kitesurfers, with significant differences occurring only between wakeboarders and kitesurfers with loop bindings and between kitesurfers with loop bindings and fixed bindings. High mean forces occurred during the landing of wakeboarders (rear foot 24.24 N/kg ± 8.82; front foot 20.33 N/kg ± 5.05) compared to kitesurfers with loop bindings (rear foot 12.09 N/kg ± 5.6; front foot 12.23 N/kg ± 4.92) as well as partially in kitesurfers with fixed shoe bindings (front foot 13.61 N/kg ± 5.92). Forces during lift-off were comparable in the rear foot (wakeboarders, kitesurfers with fixed bindings, kitesurfers with loop bindings 14.17 ± 6.37 vs. 16.39 ± 4.99 vs. 14.72 ± 5.13 N/kg). Similarly, despite the higher average acceleration force of the wakeboarders (4.16 g ± 1.02), there was no statistically significant difference (p = 0.166) compared to the kitesurfers.The in-vivo forces acting on the lower extremities during wakeboarding and kitesurfing are high (highest absolute values of 3012 N and relative values of 31.71 N/Kg). In addition, fixed boot bindings allow for the generation of higher forces than strap bindings. The results of our study have important implications on load control and preventive approaches in these two sports.

The aim of this study was to compare elbow joint proprioception measurements between physically disabled individuals who are active in sports and those who are not. The study included 30 athletes, 30 sedentary individuals, 30 physically disabled athletes, and 30 physically disabled sedentary individuals as volunteers. Elbow joint proprioception measurements were conducted using a sensitive digital goniometer with a precision of 1 degree. The joint position sense test method was used to perform the active angle repetition technique. Target angles were determined to be 30°, 60°, and 120°. A significant difference was observed in the comparison of proprioception between the dominant and non-dominant elbow joints of athletes and physically disabled sedentary individuals (p<0.05). Elbow joint proprioception was found to be highest in physically disabled athletes at the target angles. Conversely, the lowest elbow joint proprioception levels were found in physically disabled sedentary patients compared with the other groups.

It is known that anthropometric data (weight, height, BMI, waist circumference and WHtR) and male gender are positively correlated with greater core strength, while age is negatively correlated. For competitive athletes with no significant differences in the anthropometric data stated above, there have hardly been any studies in which isometric core strength in a seated position is quantitatively compared among athletes in different sports. This study aimed to analyse different sports in well-trained athletes using military competitive sports as an example with regard to possible differences in core strength. For this purpose, Parachuting (n=28), Military Pentathlon (n=34) and Ski Platoon (n=38) groups were compared with regard to isokinetic core strength using dynamometry in seated position. In addition to the comparison of anthropometry and isokinetic results with descriptive statistics, ANOVA and Welch-ANOVA were used to compare the means of absolute and weight-adjusted core strength. It was shown that the Ski Platoon group had significantly higher flexion peak torque values than the Military Pentathlon and Parachuting groups. Even when adjusted for weight, the values were significantly higher than those measured in the Military Pentathlon group but not significantly higher than those in the Parachuting group. For extension peak torque, it was found that the Military Pentathlon group had significantly lower values than the Ski Platoon group and, in the weight-adjusted analysis, significantly lower values than the Parachuters. Using the example of competitive military sports, this study was able to show that there are significant differences in isokinetic core strength even among professional competitive athletes.This knowledge should be used to carry out detailed quantitative analyses of core strength, even in well-trained professional athletes, to find applications for prevention or to coordinate compensating exercises.

Football is a popular sport on a global scale, and injuries sustained by football players have become a significant concern for sports physicians and researchers. Among these injuries, knee injuries are a commonly encountered problem in football players with long-term effects. This paper aims to perform a visual mapping and a bibliometric analysis of research on knee injuries in football, examining the current state and research trends. For this purpose, all publications from the Social Sciences Citation Index (SSCI), Science Citation Index Expanded (SCIE), Emerging Sources Citation Index (ESCI), and Arts & Humanities Citation Index (AHCI) within the Web of Science database were analysed. VOSviewer 1.6.18 was utilised for visualising bibliometric data. A total of 2159 publications were included in the study. The analysis covers publication year, authors, citation counts, and distributions among publishing journals. Authors, institutions, and international relationships were investigated, and keyword analysis, bibliometric coupling, and co-citation network analyses were conducted. The findings reveal that the United States and Australia are the countries with the highest number of publications. From 2018, there has been a noticeable increase in the number of publications. Citation and publication counts reached their peak in 2021. Turkey takes the 28^th rank in terms of citation and centrality. The keywords "soccer," "football," "knee", and "anterior cruciate ligament" were found to be intensively used with high centrality. In conclusion, visual mapping through bibliometric analysis highlights the magnitude and diversity of research in the field of knee injuries in football. It emphasises the need for further studies in this area for future researchers, shedding light on important research areas. Moreover, it provides insights into the prevention of such injuries in football players and the development of effective treatment strategies by fostering more knowledge and understanding of knee injuries.

Greater levels of physical fitness have been linked to improved dance performance and decreased injury incidence. The aim was to review the efficacy of physical fitness training on dance injury. The electronic databases CINAHL, Cochrane Library, PubMed, Web of Science, MEDLINE, China National Knowledge Infrastructure were used to search peer-reviewed published articles in English or Chinese. Studies were scored using Strength of the Evidence for a Conclusion and a risk bias checklist. 10 studies met the inclusion criteria from an initial 2450 publications. These studies offered physical fitness training for professional (n = 3) and pre-professional dancers (n = 7), participant sample size ranged between 5 to 62, ages from 11 to 27 years, and most participants were females. Assessment scores were classified as Fair (n = 1), Limited (n = 7), and Expert Opinion Only (n = 2) and risk of bias scores ranged from 22.7-68.2 %. After physical fitness training, 80 % of studies reported significant benefits in injury rate, the time between injuries, pain intensity, pain severity, missed dance activities and injury count. This review suggests that physical fitness training could have a beneficial effect on injury incidence in dance. The evidence is limited by the current study methodologies.
