- The incidence of anterior cruciate ligament (ACL) injury remains high in young athletes. Because female athletes have a much higher incidence of ACL injuries in sports such as basketball and team handball than male athletes, the IOC Medical Commission invited a multidisciplinary group of ACL expert clinicians and scientists to (1) review current evidence including data from the new Scandinavian ACL registries; (2) critically evaluate high-quality studies of injury mechanics; (3) consider the key elements of successful prevention programmes; (4) summarise clinical management including surgery and conservative management; and (5) identify areas for further research. Risk factors for female athletes suffering ACL injury include: (1) being in the preovulatory phase of the menstrual cycle compared with the postovulatory phase; (2) having decreased intercondylar notch width on plain radiography; and (3) developing increased knee abduction moment (a valgus intersegmental torque) during impact on landing. Well-designed injury prevention programmes reduce the risk of ACL for athletes, particularly women. These programmes attempt to alter dynamic loading of the tibiofemoral joint through neuromuscular and proprioceptive training. They emphasise proper landing and cutting techniques. This includes landing softly on the forefoot and rolling back to the rearfoot, engaging knee and hip flexion and, where possible, landing on two feet. Players are trained to avoid excessive dynamic valgus of the knee and to focus on the "knee over toe position'' when cutting.

- Standardized assessment of sports injuries provides important epidemiological information and also directions for injury prevention. Purpose To analyze the frequency, characteristics, and causes of injuries incurred during the Summer Olympic Games 2008. Study Design Descriptive epidemiology study. Methods The chief physicians and/or chief medical officers of the national teams were asked to report daily all injuries newly incurred during the Olympic Games on a standardized injury report form. In addition, injuries were reported daily by the physicians at the medical stations at the different Olympic venues and at the polyclinic in the Olympic Village. Results Physicians and/or therapists of 92 national teams covering 88% of the 10 977 registered athletes took part in the study. In total, 1055 injuries were reported, resulting in an incidence of 96.1 injuries per 1000 registered athletes. Half of the injuries (49.6%) were expected to prevent the athlete from participating in competition or training. The most prevalent diagnoses were ankle sprains and thigh strains. The majority (72.5%) of injuries were incurred in competition. One third of the injuries were caused by contact with another athlete, followed by overuse (22%) and noncontact incidences (20%). Injuries were reported from all sports, but their incidence and characteristics varied substantially. In relation to the number of registered athletes, the risk of incurring an injury was highest in soccer, taekwondo, hockey, handball, weightlifting, and boxing (all ≥15% of the athletes) and lowest for sailing, canoeing/kayaking, rowing, synchronized swimming, diving, fencing, and swimming. Conclusion The data indicate that the injury surveillance system covered almost all of the participating athletes, and the results highlight areas of high risk for sport injury such as the in-competition period, the ankle and thigh, and specific sports. The identification of these factors should stimulate future research and subsequent policy change to prevent injury in elite athletes.

Pronociceptive and antinociceptive neuromediators in patellar tendinopathy

- The occurrence of nerve ingrowth and its relation to chronic tendon pain (tendinopathy) are still largely unknown. In healthy tendons, the innervation is confined to the paratenon, whereas the tendon proper is devoid of nerve fibers. In this study on the pathogenesis of tendinopathy, the authors examined sensory and sympathetic nerve fiber occurrence in the patellar tendon. Hypothesis Nerve ingrowth and altered expression of sensory and sympathetic neuromediators play a major role in the pathophysiology of pain in patellar tendinopathy. Study Design Case control study; Level of evidence, 3. Methods Biopsies from the patellar tendon in patients with patellar tendinopathy (n = 10) were compared with biopsies from a control group (n = 10) without any previous or current knee symptoms compatible with patellar tendinopathy. The biopsies were stained immunohistochemically for sensory and autonomic nerve markers. The biopsies from the 2 groups were compared using subjective and semiquantitative methods. Results Chronic painful patellar tendons exhibited increased occurrence of sprouting nonvascular sensory, substance P–positive nerve fibers and a decreased occurrence of vascular sympathetic nerve fibers, positive to tyroxin hydroxylase, a marker for noradrenaline. Conclusion The altered sensory-sympathetic innervation suggests a role in the pathophysiology of tendinopathy. Ingrowth of sprouting substance P fibers presumably reflects a nociceptive and maybe a proliferative role, possibly as reactions to repeated microtraumata, whereas the decreased occurrence of tyroxin hydroxylase may represent a reduced antinociceptive role. These findings could be used to develop targeted pharmacotherapy for the specific treatment of tendinopathy.

- This qualitative study explores how 29 Swedish patients with Multiple Endocrine Neoplasia type 1 (MEN1) experience living with the condition, appraisal of the clinical follow-up program, and surveys their future expectations. The aim of this study is to build knowledge about this patient group in order to provide optimal care. The participants describe physical, psychological, and social limitations in their daily activities and how these limitations influence quality of life. Our findings indicate that a majority of patients have adjusted to their situation, describing themselves as being healthy despite physical symptoms and treatment. The participants received decent care in the clinical follow-up program, - however, greater effort should be put into patient information. These patients might benefit from genetic counseling. Health professionals involved should recognize their potential impact and influence on a patient’s ability to adjust to these circumstances. Antonovsky`s Sense of Coherence theory is used to discuss these findings.
