“…27 Harilainen et al's study of ACL reconstruction with hamstring tendons, the arthrometry results and IKDC scores of cross-pin versus metal interference screw femoral fixation were compared at 1 or 2 year follow-up examinations, and no statistically significant difference was found between both groups. 28 There is no consensus on femoral fixation of the hamstring tendon in anterior cruciate ligament reconstruction.…”

ÖZETAmaç: Hamstring tendonları kullanılarak yapılan ön çap-raz bağ (ÖÇB) rekonstrüksiyonlarında EndoButton ve cross-pin femoral tespit yöntemlerinin klinik sonuçlarının karşılaştırılması. Hastalar ve yöntem:Kliniğimizde Ocak 2006 -Aralık 2009 tarihleri arasında ÖÇB rüptürü nedeniyle opere edilen hastalar geriye dönük olarak incelendi. Hastaların 50 tanesine cross-pin, 50 tanesine ise EndoButton yöntemi kullanılarak, otojen hamstring tendon grefti ile artroskopik ön çapraz bağ rekonstrüksiyonu yapılmıştı. Her iki grupta hastaların ameliyat öncesi ve sonrası klinik değerlendir-mesi uluslararası diz dökümantasyon sistemi (IKDC) ve Lysholm II skorlama sistemine göre yapıldı. Sonuçlar:Ameliyat sonrası cross-pin grubunda IKDC skorlama sistemine göre hastaların, %52'sinde A, %40'ında B, %8'inde C skoru bulundu. EndoButton grubunda hastaların %48'inde A, %42'sinde B, %10'unda C skoru bulundu. Ameliyat sonrası cross-pin grubunda Lysholm II skorlama sistemine göre hastaların %48'inde mükemmel, %44'ünde iyi ve %8'inde orta sonuç bulundu. EndoButton grubunda hastaların %50'sinde mükemmel, %44'ünde iyi, %6'sında orta sonuç bulundu. Gruplar arasında ek hastalık, IKDC ve Lysholm II skorları ve komplikasyonlar açısından fark yoktu. EndoButton grubunda ortalama ameliyat süresi daha kısaydı. Sonuç:Her iki femoral tespit tekniğinin, klinik sonuçları arasında istatistiksel olarak anlamlı fark bulunmadı. Ameliyat süresinin daha kısa, öğrenme eğrisinin daha kolay oluşu ÖÇB rekonstrüksiyonunda EndoButton tekniğinin avantajlarıdır.Anahtar kelimeler: Ön çapraz bağ, hamstring tendon grefti, femoral tespit ABSTRACT Objectives: A comparison of the clinical outcomes of EndoButton and cross-pin femoral fixation techniques in anterior cruciate ligament (ACL) reconstruction using hamstring tendons. Materials and methods:In our clinic, between January 2006 and December 2009 patients who underwent surgery due to ACL rupture were retrospectively reviewed. Of the patients, 50 underwent arthroscopic anterior cruciate ligament reconstruction with an autogenous hamstring tendon graft using the cross-pin technique, and the remaining 50 patients underwent arthroscopic anterior cruciate ligament reconstruction with the EndoButton technique. Preoperative and postoperative clinical evaluation of the patients in both groups was performed according to the International Knee Documentation Committee (IKDC) and Lysholm II knee scoring systems. Results:In the cross-pin group, 52% of the patients had IKDC scores of A, 40% B and 8% C in the last control. In the EndoButton group, 48% of the patients had IKDC scores of A, 42% B and 10% C. Postoperatively, 48% of the patients in the cross-pin group had excellent, 44% good and 8% fair Lysholm scores. Fifty percent of the patients in the EndoButton group had excellent, 44% good and 6% fair Lysholm scores. There was no difference between the groups in additional diseases, IKDC and Lysholm scores and complications. The mean operative time was shorter in the EndoButton group. Conclusions

“…Para evitar que os dados de força versus deslocamento sejam poluídos, tentou-se ao máximo limitar as variáveis do sistema [8][9][10] . Sendo assim, foi necessário o desenvolvimento de um sistema de garras e simuladores de fixação com alta resistência, para que a falha ocorresse no tendão, evitando-se novas variáveis.…”

OBJETIVO: Avaliar a diferença do comportamento mecânico de tendões flexores solidarizados e não solidarizados para verificar se a solidarização tem função efetiva. MÉTODOS: Vinte e quatro tendões digitais bovinos frescos foram usados. Para determinar a área da secção transversal utilizou-se alginato. Dez tendões foram solidarizados seguindo as orientações do fabricante; outros 10 pares não. Foram desenvolvidas garras para fixação dos enxertos à máquina universal para simulação da fixação, sendo a superior bipartida e de passagem controlada dos pinos e a inferior com dentes alternados. RESULTADOS: A carga máxima dos corpos de prova não solidarizados foi de 849,4 N ± 386,8 a área 30,4 mm²± 7,7, tensão de 29 ± 17 Mpa. Os solidarizados obtiveram carga máxima de 871,8 N ± 484,9 área 35 mm²± 5,8, tensão de 24 ± 10 Mpa. Não houve diferença estatística entre os dois grupos (p>0,05). CONCLUSÃO: A distribuição de probabilidade mostra que para 400 N os tendões não solidarizados apresentam confiabilidade de 83,8% e os solidarizados de 78,5%%.

“…The most rapid healing time at the insertion sites found with this graft choice with 360 degree bone-to-bone (block-totunnel) union occurs within 4 to 6 weeks, similar to fracture healing 12,13 . Even though some of the biomechanical and clinical studies came up with comparable pullout strength for cross pins [14][15][16][17][18] , a limited number of studies showed increased slippage and inferior pull out strength 19 . Even though there are some studies to evaluate Rigidfix femoral fixation in hamstring tendon there are no clinical studies to show the functional outcome of cross pin femoral fixation in BTB autograft in literature.…”

SummaryBackground: Arthroscopic reconstruction of torn Anterior Cruciate Ligament (ACL) with bone patellar tendon bone autograft (BTB) has become the gold standard in treating ACL tear with high success rate. The purpose of this study was to prospectively evaluate the functional outcome after arthroscopic ACL reconstruction using BTB via Rigidfix femoral fixation. Materials and method: We evaluated the result of 21 knees that have been treated with arthroscopic ACL reconstruction using BTB autograft for femoral fixation and bioabsorbable interference screw for tibia from March 2014 to August 2015. The mean follow up period was 18 months. Results and conclusion: The Lysholm score postoperatively was 89.04. 23.8% of the 21 patients have good to excellent outcome, 66.7% patients have good to fair outcome and 9.5% patient have fair outcome. Level of Evidence: IV.
