Abstract

Objective: Since, there is no standardized technique for the treatment of focal cartilage defects that can recreate original cartilage tissue; researchers continue to explore and evaluate various treatment modalities. This study compared post-operative healing of cartilage defects after treatment with small-diameter-hole microfracture (SDHM) technique with that of traditional microfracture technique. The effects of the hole density and augmentation with hyaluronic acid-based acellular matrix (HA-based AM) on cartilage healing were also investigated.Methods: Articular cartilage defects measuring 5 mm in diameter and 3 mm in depth were created in each femoral trochlear groove of 21 New Zealand rabbits. Rabbits were assigned to seven groups comprising six knees each. The rabbits were sacrificed 12 weeks later, and the regenerated cartilage was harvested for histological evaluation using the Wakitani scoring system.Results: All defects were filled with regenerated tissue macroscopically. Group I (14; range 10-14 points) had significantly higher Wakitani score than in groups VI (6; range 1-11 points) and VII (5; range 3-10 points) (p=0.043 and p=0.016, respectively). No significant differences were observed among the other groups. Augmentation with HA-based AM did not contribute to cartilage healing.Conclusion: Improved cartilage healing was observed with increasing SDHM density than with traditional microfracture technique. SDHM combined with HA-based AM implantation did not improve the quality of the regenerated cartilage.

Özet

Amaç: Fokal kıkırdak defektlerinin tedavisinde hala orijinalkıkırdak dokusu sağlayan mükemmel bir yöntem yoktur, bunedenle en iyi tedavi seçeneklerini bulmak için araştırmalar devametmektedir. Bu çalışmada amaç, kıkırdak defektlerinde küçük çaplıdelik (SDHM) ve geleneksel mikro kırık tedavilerinin iyileştirmekalitesini karşılaşmaktır. Bununla beraber delik yoğunluğununve defekti hyalüronik asit bazlı aselüler matriks (HA bazlı AM)ile desteklemenin kıkırdak iyileşmesi üzerindeki etkileri deincelenmiştir. Yöntemler: Yirmi bir Yeni Zelanda tavşanının her iki femurtrochlear oluğunda 5 mm çapında ve 3 mm derinliğinde artikülerkıkırdak defekti oluşturuldu. Her biri 6 dizden oluşan yedi grupoluşturuldu. Tavşanlar 12 hafta sonra sakrifiye edildi ve rejenerekıkırdak Wakitani skorlama sistemi kullanılarak histolojikdeğerlendirme için toplandı. Bulgular: Tüm defektler rejenere doku ile makroskopik olarakdolduruldu. 1. Grup [14 (10-14) puan], VI [6 (1-11) puan] ve VII.[5 (3-10) puan] gruplara göre anlamlı derecede yüksek Wakitani skoruna sahipti (p=0.043 ve p=0.016 ). Diğer gruplar arasındaanlamlı bir fark gözlenmedi. Hyaluronik asit bazlı aselüler matriksile destekleme, kıkırdak iyileşmesine katkıda bulunmadı. Sonuç: SDHM yoğunluğunun artırılması, geleneksel mikro kırıkile karşılaştırıldığında kıkırdak iyileşmesini artırır. Hyalüronik asitbazlı aselüler matriks implantasyonu ile desteklenen SDHM’ninartırılması ise rejenere kıkırdak kalitesini artırmadı.
