Comparison of repair techniques in small and medium-sized rotator cuff tears in cadaveric sheep shoulders

Abstract

Objective: The aim of this study was to compare new knotless single-row and double-row suture anchor techniques with traditional transosseous suture techniques for different sized rotator cuff tears in an animal model. Methods: The study included 56 cadaveric sheep shoulders. Supraspinatus cuff tears of 1 cm repaired with new knotless single-row suture anchor technique and supraspinatus and infraspinatus rotator cuff tears of 3 cm repaired with double-row suture anchor technique were compared to traditional transosseous suture techniques and control groups. The repaired tendons were loaded with 5 mm/min static velocity with 2.5 kgN load cell in Instron 8874 machine until the repair failure. Results: The 1 cm transosseous group was statistically superior to 1 cm control group (p=0.021, p<0.05) and the 3 cm SpeedBridge group was statistically superior to the 1 cm SpeedFix group (p=0.012, p<0.05). The differences between the other groups were not statistically significant. Conclusion: No significant difference was found between the new knotless suture anchor techniques and traditional transosseous suture techniques

Kadavra koyun omuzlarında küçük ve orta boy rotator manşet yırtıklarında yırtık boyutu ile dikiş tekniğinin karşılaştırılması

Abstract

Amaç: Bu çalışmada farklı uzunluktaki rotator manşet yırtıklarında yeni düğümsüz tek sıralı ve çift sıralı dikiş ankor teknikleri ile geleneksel transosseöz dikiş teknikleri ile karşılaştırıldı. Çalışma planı: Elli altı kadavra koyun omuzunda, tek sıralı düğümsüz ankor tekniği ile onarılan 1 cm’lik supraspinatus manşet yırtıkları ve çift sıralı düğümsüz ankor tekniği ile onarılan 3 cm’lik supraspinatus ve infraspinatus rotator manşet yırtıkları geleneksel transosseöz dikiş teknikleri ve kontrol grupları ile karşılaştırıldı. Onarılan tendonlar, Instron 8874 cihazına bağlanarak 2.5 kgN yük hücresi kullanılarak 5mm/dk statik hız ile yapılan onarım kopana dek çekildi. Bulgular: İstatistiksel olarak karşılaştırıldığı zaman 1 cm’lik transosseöz grubunun 1 cm’lik kontrol grubuna göre (p=0.021, p<0.05), 3 cm’lik SpeedBridge grubunun 1 cm’lik SpeedFix grubuna göre anlamlı bir şekilde üstün olduğu (p=0.012, p<0.05) saptandı. Diğer gruplar arasında anlamlı bir farklılık görülmedi. Çıkarımlar: Yeni düğümsüz dikiş ankor teknikleri ile geleneksel transosseöz dikiş teknikleri arasında anlamlı bir farklılık gözükmemektedir.
