Abstract

Objectives: This study aims to perform an experimental examination of the patellar tendon grafts repaired using an interference screw and free tendon graft. Material and methods: Twelve knees of the lower limbs which were amputated due to circulatory disease were included in this study. The knees were removed from all soft tissues including patellar tendons. A tendon graft was fixed onto tuberositas tibia through the distal portion of the knee using an interference screw. The patellar tendon graft and tuberositas tibia complex were fixed at the lower and upper part of the testing machine. The distraction force of the bone- tendon-bone complex was recorded using the testing machine. Results: Both patellar and tibial ruptures were detected. The pullout force of the tendons was found to be 810 at maximum and 420 N at minimum. The mean pullout force was 600 N in men and 525 N in women with an overall mean of 575 N. Conclusion: Our study results showed that patellar tendon repair with grafting had a similar pullout force compared to other repair techniques. In case of a neglected rupture of the patellar tendon, in particular, grafting is recommended.

Özet

Amaç: Bu çalışmada patellar tendon yırtıklarının interferensvidası ve serbest tendon grefti kullanarak tamirlerinin biyo-mekaniğinin deneysel incelenmesi amaçlandı.Gereç ve yöntemler: Bu çalışmada dolaşım bozukluğu nedeniyle ampute edilmiş alt ekstremitelerden elde edilen 12 diz kullanıldı. Dizler patellar tendonu dahil bütün yumuşak dokulardan temizlendi. Tendon grefti dizin distal kısmı ile tuberositas tibiaya interferens vidası ile tespit edildi. Patellatendon grefti-tuberositas tibia kompleksi test makinasının alt ve üst çenesine tespit edildi. Kemik-tendon-kemik kompleksi distraksiyon kuvveti test makinası vasıtasıyla uygulanarak kayıt edildi. Bulgular: Kopmanın hem patellar hem tibial taraftan olduğu görüldü. Tendonların kopma kuvveti en yüksek 810 N, en düşük 420 N olarak bulundu. Tendonların kopma kuvveti erkeklerde ortalama 600 N, kadınlarda ortalama 525 N, genel ortalama ise 575 N idi. Sonuç: Çalışma bulgularımız, greftleme ile tamir edilen patellar tendonun diğer tamir yöntemleriyle mukayese edildiğinde benzer kopma kuvvetine sahip olduğunu göstermektedir. Özellikle patellar tendonun kaybedildiği durumlarda greftleme önerilmektedir.
