Functional Outcome of Lateral Extraarticular Tenodesis (LET) Procedure in Addition to Anterior Cruciate Ligament Reconstruction: A Metaanalysis / Resultado funcional do procedimento de tenodese extra-articular lateral (TEL) como complemento à reconstrução do ligamento cruzado anterior: Uma metanálise

Abstract Objectives The aim of the present study is to systematically review and analyze the functional outcome of lateral extraarticular tenodesis (LET) procedure in addition to anterior cruciate ligament reconstruction (ACLR) in studies with a high level of evidence. Methods We performed a literature search for clinical studies comparing the LET method as an augmentation to ACL reconstruction with ACL reconstruction alone. The primary outcomes were the International Knee Documentation Committee (IKDC) score, the Lysholm score, and graft failures. Continuous variables were reported as means and 95% confidence intervals (CIs). Results Six clinical studies with 1,049 patients were included in the metaanalysis. The follow-up period was, in average, 24 months (range, 6-63 months). The addition of the LET procedure to ACLR results in better functional outcome based on the IKDC score (p< 0.05). Graft failure was found to be lower in the ACLR plus LET group (16 of 342 patients) compared with the ACLR-only group (46 of 341 patients) (p< 0.05). Conclusion There is high-level evidence that LET procedure in addition to ACLR is preferable in terms of functional outcome and graft failure.

Resumo Objetivos O objetivo deste estudo é revisar e analisar sistematicamente o desfecho funcional do procedimento de tenodese extra-articular lateral (TEL) em complemento à reconstrução do ligamento cruzado anterior (RLCA) em de estudos com alto nível de evidências. Métodos Realizamos a pesquisa bibliográfica para estudos clínicos comparando o método TEL como complemento à RCLA com a RLCA isolada. Os resultados principais foram a pontuação no Comitê Internacional de Documentação de Joelho (IKDC, na sigla em inglês), pontuação de Lysholm, e falhas no enxerto. Variáveis contínuas foram relatadas, como médias e intervalos de confiança (ICs) de 95%. Resultados Seis estudos clínicos com 1,049 pacientes foram incluídos na metanálise. O período de seguimento foi de, em média, 24 meses (intervalo de 6-63 meses). A adição do procedimento TEL à reconstrução do LCA resultou em melhor resultado funcional com base no escore IKDC (p< 0,05). A falha do enxerto foi menor no grupo RLCA mais TEL (16 dos 342 pacientes) em comparação com o grupo apenas RLCA (46 dos 341 pacientes) (p< 0,05). Conclusão Há evidências de alto nível de que o procedimento TEL como complemento à RLCA é preferível em termos de resultado funcional e falha do enxerto.

Comparison of mortality rate between bipolar hemiarthroplasty and proximal femoral nail anti-rotation for intertrochanteric fractures in Sanglah hospital, Bali

Introduction: Intertrochanteric fractures occur in about 50% of all hip fracture events, with a mortality rate within 1 year after fracture reaching 15 to 20%. The most common treatment nowadays is either the bipolar hemiarthroplasty procedure or proximal femoral nail anti-rotation (PFNA), although there is still no consensus regarding which is better from the two, especially on patient mortality.Method: This study was an observational study using a retrospective cohort design. A total of 102 study subjects who met the inclusion requirements were grouped into 2 groups, one with bipolar hemiarthroplasty fixation treatment and another with PFNA fixation treatment. Mortality rate was recorded by survey 2 years after surgery.Result: Chi-square test showed that 2-year mortality rate after intertrochanteric fracture treated with bipolar hemiarthroplasty (21.4%) was significantly higher than the PFNA group (10.3%) (p=0.028). Bipolar hemiarthroplasty group also had longer length of stay (LoS) (50%) than the PFNA group (32.4%), albeit statistically insignificant (p=0.13). There was no significant difference between the 2-year mortality rate and LoS (p=0.976).Conclusion: Patients with intertrochanteric fractures who underwent bipolar hemiarthroplasty have significantly higher 2-year mortality rate than similar patients underwent fixation with PFNA, while they did not experience higher LoS than the PFNA group. Future prospective, multi-center study with larger sample size will be likely to validate similar fixation choice needed to decrease the mortality rate in intertrochanteric fractures.
