Patients with noncontact ACL injury presented a greater alpha angle when compared with the group without tear. There was no difference in the rotational mobility of the hip between groups, nor was there a correlation between the increase in the alpha angle and the decrease in the rotational mobility of the hip.

Resumo Objetivo Avaliar a força de resistência à tração de diferentes métodos de fixação tibial na reconstrução do ligamento anterolateral (LAL). Além disso, comparar os mecanismos de falha da fixação tibial dessa reconstrução em joelhos suínos. Métodos Foram usados 40 membros recém-congelados de suínos, divididos em quatro grupos de dez espécimes, conforme as técnicas de fixação tibial usadas. No grupo A, a fixação tibial do enxerto tendíneo foi feita por meio de uma âncora e seu fio transpassou o enxerto. No grupo B, a fixação tibial foi feita por meio de parafuso de interferência metálico em túnel ósseo único. No grupo C, a fixação tibial incluiu uma âncora associada à sutura de ponto sobre o tendão (sem a presença de fio que transpassasse o tendão) e, no grupo D, foram usados dois túneis ósseos confluentes associados a um parafuso de interferência em um dos túneis. Resultados A força média menos elevada (70,56 N) ocorreu no grupo A e a mais elevada (244,85 N), no grupo B; as médias dos outros dois grupos variaram entre 171,68N (grupo C) e 149,43 N (Grupo D). Considerando-se a margem de erro fixada (5%), foi observada diferença significativa entre os grupos (p < 0,001). Conclusão A fixação com parafuso de interferência em túnel ósseo único apresentou a maior força de resistência à tração dentre as técnicas avaliadas.

Total knee arthroplasty (TKA) is a very efficient surgical process in the treatment of degenerative knee changes. However, this procedure involves extensive tissue trauma, which contributes to the occurrence of severe postoperative pain. In this sense, pregabalin seems to be effective when administered before surgery with significant pain reduction and consequently the amount of opioid used postoperatively. Considering the importance of the subject and considering that there is no work in Alagoas and or Northeast Brazilian populations that justifies the advantages of using Pregabalin in the preoperative period of TKA, this study aims to gather information collected from patients operated at Santa Casa de Misericórdia de Maceió in a period of one year. Thirty-six patients were studied during the research, where four were excluded due to data collection failure. The main indications for TKA were 2 patients with rheumatoid arthritis, 16 with arthrosis and 13 with refractory pain. In this context, pregabalin has recognized side effects, but in the study, it was observed safety in the administration of this drug in the patient group 24 hours before the surgical procedure compared to the patient group 1 hour earlier as shown in Table 1. A greater reduction was observed. of pain according to VAS pain 24 and 48 hours after surgery, in the pregabalin group 24 hours before, in relation to the others. No decrease in postoperative opiod use was observed, as no study group achieved a VAS pain lower than 3 points over the length of stay. Therefore, a larger study with larger patient samples and case-controls is needed to obtain significant results.
