RESUMEN

The posterolateral corner is critical to knee stability. Neglected injuries have a direct impact on the prognosis due to residual instability, chronic pain, deformities, and failure to repair other structures. Several techniques are used to reconstruct the posterolateral corner, often with autologous ischiotibial grafts or homologous grafts. An option little used for knee ligament reconstructions is the peroneus longus tendon graft. Although reported as a good alternative for anterior cruciate ligament reconstruction, we found no case using a peroneus longus tendon graft for posterolateral corner reconstruction. Here, we describe the case of a patient who underwent a non-anatomical reconstruction of the posterolateral corner using a peroneus longus tendon graft. The patient underwent surgical procedures for ligament reconstruction and correction of the deformity caused by a failed graft, but his knee remained unstable. During the preoperative planning, it was decided to reconstruct the posterolateral corner with an ipsilateral peroneus longus tendon graft. Studies have shown that the peroneus longus tendon graft does not increase ankle morbidity, and that its length and diameter favor ligament reconstruction. Thus, the present article highlights the importance of the proper diagnosis of ligament injuries in the acute phase, and describes a new technique for posterolateral corner reconstruction that must be included in the surgeon's body of knowledge, increasing the amount of technical options.

Resumo O canto posterolateral tem grande importância na estabilidade do joelho. Sua lesão pode ser negligenciada, o que tem um impacto direto no prognóstico e resulta em instabilidade residual, dor crônica, deformidades e falha do reparo de outras estruturas. Existem diversas técnicas de reconstrução do canto posterolateral e o uso de enxertos autólogos dos isquiotibiais ou homólogos são as mais comuns. Uma opção pouco utilizada para reconstruções ligamentares no joelho é o enxerto do tendão fibular longo. Apesar de descrito como boa opção na reconstrução do ligamento cruzado anterior, não foi encontrado nenhum caso de uso do enxerto do tendão fibular longo na reconstrução do canto posterolateral. Neste artigo, descrevemos o caso de um paciente submetido a reconstrução não anatômica do canto posterolateral com uso do enxerto do tendão fibular longo. O paciente foi submetido a procedimentos cirúrgicos para reconstrução ligamentar e correção de deformidade ocasionada pela falha do enxerto, mas manteve instabilidade ligamentar. No planejamento pré-operatório, optou-se pela reconstrução do canto posterolateral com enxerto do tendão fibular longo ipsilateral. Estudos evidenciaram que o enxerto do tendão fibular longo não provoca aumento de morbidadeem relação aotornozelo abordado, bem comoseapresenta com comprimento e diâmetro favoráveis à reconstrução ligamentar. Dessa forma, este artigo aponta para a importânciadodiagnóstico correto das lesões ligamentaresnafase aguda,e para uma nova técnica na reconstrução do canto posterolateral, que deve fazer parte do arsenal de conhecimentos do cirurgião, pois aumenta as opções de técnicas.

RESUMEN

BACKGROUND: Anterior cruciate ligament (ACL) reconstruction is usually performed with autologous bone-patellar tendon-bone (PT) or hamstring tendon (HT) graft. There has been only 1 randomized clinical trial examining ACL reconstruction with these grafts specifically in soccer players, and more studies comparing these graft types within a homogenous cohort such as soccer athletes may better highlight differences in outcomes. PURPOSE: To compare the results of ACL reconstruction with PT versus HT autograft in soccer players and to evaluate objective and subjective outcomes. STUDY DESIGN: Randomized controlled trial; Level of evidence, 1. METHODS: A total of 62 professional or semiprofessional soccer players (mean age, 25.1 years) with ACL injury were randomized to undergo reconstruction with PT or HT autograft by a single orthopaedic surgeon (n = 31 in each group). Outcome measures were recorded preoperatively and at 2 years postoperatively. The primary outcome was the modified Cincinnati Knee Rating System, and secondary outcomes were the objective and subjective International Knee Documentation Committee scores, Lachman test, pivot-shift test, anterior drawer test, and Lysholm score. The following variables were also evaluated postoperatively: return to soccer, level at return, graft rerupture, postoperative complications, anterior knee pain, patellar tendinitis, difficulty sprinting, and loss of kicking power. RESULTS: The PT and HT groups were homogenous in terms of age, sex distribution, injured side, and time from injury to surgery, and there was no difference between them on any preoperative outcome score. At 2 years postoperatively, there were no differences between the groups on any outcome score; however, there were significantly fewer patients with anterior knee pain in the HT group compared with the PT group (7 [22.6%] vs 15 [48.4%], respectively; P = .03). Two patients from each group (2/31; 6.5%) sustained rerupture. CONCLUSION: There were no differences between soccer players who underwent different types of ACL reconstruction with the exception of anterior knee pain, which was more frequent in players who underwent reconstruction with PT graft.Registration: NCT02642692 (ClinicalTrials.gov).

RESUMEN

In clinical practice, it is observed that the hamstring tendon graft, despite being first choice in knee ligament reconstruction, may not present adequate size. Therefore, it becomes necessary to search for other graft alternatives. In this context, the peroneus longus tendon arises as an option to replace or complement other grafts. The surgeon can opt to use the tendon in its totality or only its anterior half, presenting adequate length, diameter, and biomechanics, without major repercussions for the donor site. In this study, we report a case of an athlete in which the autologous hamstring tendon graft did not present the adequate diameter for anterior cruciate ligament reconstruction. It was, then, necessary to use the anterior half of the peroneus longus tendon.

RESUMEN

OBJECTIVE: To identify the risk factors correlated with the initial treatment performed. METHODS: This is a retrospective study involving a total of 272 patients diagnosed with femoral shaft fractures. Of the patients, 14% were kept at rest until the surgical treatment, 52% underwent external fixation, 10% received immediate definitive treatment, and 23% remained in skeletal traction (23%) until definitive treatment. RESULTS: There were six cases of fat embolism syndrome (FES), which showed that polytrauma is the main risk factor for its development and that initial therapy was not important. CONCLUSION: Polytrauma patients have a greater chance of developing FES and there was no influence from the initial treatment.

OBJETIVO: Identificar os fatores de risco e correlacioná-los com o tratamento inicial. MÉTODOS: Estudo retrospectivo que envolveu 272 pacientes com diagnóstico de fratura diafisária de fêmur; 14% permaneceram em repouso até o tratamento cirúrgico, 52% foram submetidos a fixação externa, 10% fizeram o tratamento definitivo imediato e 23% permaneceram com tração esquelética até o tratamento definitivo. RESULTADOS: Foram seis casos de síndrome da embolia gordurosa (SEG), nos quais se evidenciou que o politrauma é o principal fator de risco para seu desenvolvimento e que o tratamento inicial instituído não o influenciou. CONCLUSÃO: Pacientes politraumatizados apresentaram uma maior chance de desenvolver SEG e não houve influência do tratamento inicial instituído.
