ÖZET
Amaç:
Unikondiler diz artroplastisinde (UDA) aseptik gevşeme başarısızlığın en önemli nedenlerinden biridir. Bu çalışmanın amacı, tasarımcı olmayan bir grup kohortunda çimentosuz ve çimentolu UDA’lar arasındaki erken fizyolojik ve patolojik radyolusent hatları (RLH) karşılaştırmaktı.
Yöntemler:
Bu çalışmada 2012-2018 yılları arasında 38 çimentolu UDA ve 47 çimentosuz UDA uygulanan iki hasta grubu retrospektif olarak karşılaştırıldı. Hastaların klinik sonuçlarının değerlendirilmesinde Oxford Diz Skoru, EQ-5D-3L, EQ-VAS ve KOOS skorlamaları kullanıldı. RLH’lerin varlığının değerlendirilmesinde, tibial ve femoral bileşen ara yüzleri bölgelere bölündü ve RLH’ler için değerlendirildi.
Bulgular:
Klinik sonuçlar açısından gruplar arasında istatistiksel olarak anlamlı fark yoktu (p>0,05). Hiçbir hastada femoral veya tibial bileşen ara yüzlerinde tam RLH gözlenmedi. Tibial bileşen ara yüzünde parsiyel radyolusent bölgeler çimentolu UDA’larda 32 (%11,3) ve çimentosuz UDA’larda 13 (%5,7) bölgede tespit edildi. Tibial bileşen arayüzünde kısmi RLH görülme sıklığı ve toplam radyolusent bölge sayısı çimentolu artroplastilerde daha yüksekti (p=0,040 ve p=0,025).
Sonuç:
Unikondiler diz artroplastisindegözlenen aşırı fizyolojik RLH’lerin hastaların klinik sonuçları üzerinde etkisi olmadığı tespit edildi. Fizyolojik RLH oranı çimentosuz UDA’da çimentolu UDA’ya göre önemli ölçüde daha düşüktü.
