Objective: The present study aimed to retrospectively evaluate musculoskeletal injuries in elite Brazilian wrestlers. Methods: Ninety-five wrestlers completed a structured questionnaire to assess wrestling injury history and clinical and demographic data. Results: Eighty one athletes (85,3%) informed 145 lesions. The most commonly injured body regions were knee (25,5%), shoulder (20%), thigh (15,2%) and ankle (14,5%). Sprains (34,5%) and muscle lesions (30,4%) were the most common injuries. Surgical treatment was performed in 9% of the lesions and the majority of these lesions (61,5%) were located in the lower limbs. Conclusions: Musculoskeletal lesions are common in wrestling athletes and the lower limbs are the most frequently injured site.

The aim of this study was to alert doctors to the existence of Turco's injury and discus the existing treatments that have been described in the worldwide literature. A bibliographic survey of Lisfranc's injury and Turco's injury covering from 1985 to 2013 was conducted in the SciELO and PubMed databases. Among the 193 articles, those relating to bone-ligament injuries of the Lisfranc joint and high-energy trauma were excluded, as were the case reports. The patients selected were professional or amateur athletes who solely presented a ligament injury to the Lisfranc joint (Turco's injury), which was diagnosed from the history, physical examination, radiographs and magnetic resonance images. Non-athletic patients and those with associated bone injuries were excluded (10). According to the injury classification, the patients were treated by means of either an open or a closed procedure and then a standard rehabilitation protocol. Out of the 10 patients, five underwent conservative treatment and five underwent surgical treatment using different techniques and synthesis materials. We obtained two poor results, one satisfactory, five good and two excellent. We conclude that the correct diagnosis has a direct influence on the treatment and on the final result obtained, and that lack of knowledge of this injury is the main factor responsible for underdiagnosing Turco's injury. There is a need for randomized prospective studies comparing the types of synthesis and evolution of treated cases, in order to define the best treatment for this injury.

Objective: To demonstrate the safety of soccer for adolescents in terms of chronic lesions of the lumbar spine, particularly spondylolysis. Methods: 54 young players underwent a pre-season assessment. The athletes were submitted to radiography of the lumbosacral spine. Players complaining of chronic low back pain were later submitted to more specific tests. Results: only 1 athlete (1.85 % of our sample) had complaints of chronic low back pain. In this case, the radiograph showed olisthesis grade I spondylolysis at the L5 level. Conclusion: Soccer proved to be a very safe sport in terms of the risk of developing chronic lesions of the lumbosacral spine. However, the actual incidence of spondylolysis in these athletes was not determined because only plain radiographs were used in this study.Keywords: Low back pain; Athletes; Soccer; Spondylolysis.

RESUMOEsta revisão sistemática da literatura teve como objetivo analisar as variáveis envolvidas no retorno às atividades esportivas em pacientes submetidos à artroplastia total do joelho (ATJ), verificar o tipo de esporte recomendado, o tempo de retorno ao esporte, a satisfação do paciente e o nível de atividade física após a cirurgia. Os estudos relacionados com a prática de atividade física e desportiva depois da ATJ foram selecionados por dois revisores independentes. Foram incluídos 11 estudos (10 transversais retrospectivos e um caso-controle). A maioria dos pacientes que participou de alguma atividade física regular antes da ATJ retornou à prática esportiva após a cirurgia, sendo mais comuns os esportes de baixo impacto como caminhada, esportes aquáticos, golfe, bicicleta estacionária, entre outros. Foi possível observar que o nível de atividade física não depende da dor e dos sintomas pós-operatórios, mas da satisfação com a cirurgia, motivação e capacidade funcional dos indivíduos. O tempo de retorno ao esporte variou de seis a 18 meses depois da ATJ. Apesar de alguns estudos mostrarem que os cirurgiões não recomendam a prática de esportes de alto impacto após a cirurgia, alguns estudos mostraram bons resultados, desde que o nível de atividade prévio à cirurgia, a população adequada e a expectativa do paciente no pós-operatório sejam considerados. Assim, conclui-se que o retorno ao esporte após ATJ não só é possível, como é recomendado em níveis recreativos, e um paciente colaborativo, instruído e com preparo adequado de condicionamento físico pode melhorar tanto no nível funcional e cardiovascular quanto no psicológico, com aumento da autoestima e da qualidade de vida. Há ainda a necessidade de estudos futuros, de boa qualidade metodológica como os ensaios clínicos randomizados, sobre os efeitos (benefícios e prejuízos) dos esportes de alto impacto para os pacientes submetidos à ATJ.Descritores: artroplastia do joelho; exercício; esportes.
