Abstract

Objectives: This study aims to investigate the potential use and histological effects of the local administration of platelet-derived growth factor (PDGF) in the repair of full-thickness osteochondral defects in articular cartilage in an animal model. Materials and methods: Twenty-four adolescent 18-week-old New Zealand White rabbits with an average weight of 2500 g (range, 1600 g to 3200 g) were used in the study. The rabbits were randomly divided into three groups (n=8) as the control group (group A) and two experimental groups (groups B and C). Defects of cylindrical full-thickness (3.5 mm wide, 4 mm deep) were created in the weight-bearing area of the right knee medial femoral condyles. In group A, the defect was left empty. In group B, the defect was filled with a collagen sponge. In group C, the defect was filled with a collagen sponge impregnated with PDGF. All rabbits were followed-up for 12 weeks. Right knee medial femoral condyles were used for macroscopic and histological analyses. Results: At macroscopic level, the repair tissue was similar to normal adjacent cartilage at 12 weeks in group C. The surface of the repair tissue in group C was smoother and more regular compared to groups A and B. The total histological score of defects in group C was statistically significantly superior compared to groups A and B (p

Özet

Amaç: Bu çalışmada lokal trombosit türevli büyüme faktörü (TTBF) uygulamasının tam kat eklem kıkırdağının osteokondral defektlerinin tamirinde potansiyel kullanımı ve histolojik etkileri bir hayvan modelinde araştırıldı. Gereç ve yöntemler: Çalışmada ortalama ağırlığı 2500 g (dağılım, 1600 g-3000 g) olan adölesan 18 haftalık 24 Yeni Zelanda Beyaz tavşanı kullanıldı. Tavşanlar kontrol grubu (grup A) ve iki deneysel grup (grup B ve C) olmak üzere randomize olarak üç gruba (n=8) ayrıldı. Sağ diz medial femoral kondillerin yük taşıyan alanında tam kat silindirik defektler (3.5 mm eninde, 4 mm derinliğinde) oluşturuldu. Grup A’da defekt boş bırakıldı. Grup B’de defekt kollajen süngerle dolduruldu. Grup C’de defekt TTBF emdirilmiş kollajen süngerle dolduruldu. Tüm tavşanlar 12 hafta takip edildi. Sağ diz medial femoral kondiller makroskopik ve histolojik analizler için kullanıldı. Bulgular: Grup C’de makroskopik düzeyde 12 haftada tamir dokusu bitişik normal kıkırdağa benzerdi. Grup C’de tamir dokusunun yüzeyi grup A ve B’ye göre daha düz ve düzenliydi. Grup C’de defektlerin toplam histolojik skoru grup A ve B’ye kıyasla istatistiksel olarak anlamlı şekilde daha iyiydi (p
