Abstract

Objectives: The treatment of Achilles tendon disorders remains controversial. This study was designed to observe the local early and late term effects of intratendinous hylan G-F 20 injections on experimentally induced rat Achilles tendonitis. Materials and methods: After inducing Achilles degeneration with local corticosteroid injections in the Achilles tendons, 36 male Wistar rats were divided into two main groups for early (group 1) and late (group 2) term observations. The right Achilles tendons served as the hylan injection group, and the left Achilles tendons injected with saline as the control group. Injections were given at 5-day intervals until day 60 of the experiment. The tendons and paratenons were excised at the end of 60 and 75 days in group 1 and at the end of four and six months in group 2 for histopathologic and statistical evaluations.Results: Semiquantitative scoring of histopathological changes showed that histological appearances significantly differed between hylan and saline groups in the early term. Hylan-injected tendons and paratenons demonstrated significantly lower scores especially after 75 days. However, in the late period, the differences were mostly insignificant.Conclusion: Hylan G-F 20 appears to have a promising curative effect on degenerated tendon processes in the early acute and subacute periods. Further studies, either biomechanical or biochemical, will show how useful this chemical agent is in treating tendon disorders.

Özet

Amaç: Aşil tendon patolojilerinin tedavisi halen tartışmalıdır. Bu çalışmada, sıçanlarda deneysel olarak oluşturulmuş Aşil tendonitinde lokal intratendinöz hylan G-F 20 enjeksiyonlarının erken ve geç dönem etkileri araştırıldı. Gereç ve yöntem: Lokal intratendinöz kortikosteroid enjeksiyonları ile Aşil tendon dejenerasyonu oluşturulduktan sonra 36 erkek Wistar sıçanı erken (grup 1) ve geç (grup 2) dönem sonuçlar için iki gruba ayrıldı. Her sıçanın sağ Aşil tendonuna hylan, sol Aşil tendonuna serum fizyolojik enjeksiyonu (kontrol) uygulandı. Enjeksiyonlar 60. deney gününe kadar beşer gün arayla yapılacak şekilde sürdürüldü. Grup 1'deki sıçanların tendon ve paratenonları 60 ve 75. gün sonunda, grup 2'de ise dördüncü ve altıncı ay sonunda çıkartılarak histopatolojik ve istatistiksel olarak değerlendirildi.Bulgular: Histopatolojik değişikliklerin semikantitatif skorlaması, erken dönemde hylan ve serum fizyolojik grupları arasında istatistiksel anlamda önemli bir fark olduğunu gösterdi. Hylan enjekte edilen tendon ve paratenonlara ait skorlar özellikle 75. gün sonunda anlamlı derecede düşük bulundu. Geç dönemde ise gruplar arasında anlamlı fark görülmedi.Sonuç: Hylan G-F 20, akut ve subakut tendon dejenerasyonunda umut veren tedavi edici bir etki göstermiştir. Daha ileri biyomekanik veya biyokimyasal çalışmalar, bu kimyasal ajanın tendon patolojilerindeki yararını gösterecektir.
