Abstract

Amaç: Çalışmanın amacı, Oxford Faz 3 unikompartmantal diz protezi (UDP) yapılan obez hastaların orta dönemdeki protez sağ kalımlarını, lateral kompartmanda artroz gelişimini ve fonksiyonel sonuçlarını değerlendirmekti.

Çalışma planı: Ocak 2005 ile Aralık 2010 tarihleri arasında izole medial osteoartrit tanısı ile hareketli taşıyıcılı Oxford Faz 3 UDP uygulanan ve cerrahi öncesi vücut kitle indeksi 30’un üstünde olan 67 hasta çalışmaya alındı. Hastaların cerrahi öncesi ve sonrası eklem hareket açıklıkları (EHA), diz skorlamaları (Hospital for Special Surgery, HSS ve Oxford diz skoru) karşılaştırıldı. Ayrıca, son kontrollerinde protezleri Oxford radyolojik değerlendirme kriterlerine göre değerlendirildi.

Bulgular: Hastaların ortalama yaşı 61 idi. Hastalar ortalama 67.5 ay süreyle takip edildi. Üç hastada (%4.5) gelişen insert çıkığı dışında ek komplikasyon görülmedi. Cerrahi sonrası hastaların EHA, HSS ve Oxford diz skorlamalarında belirgin düzelme olduğu görüldü (p<0.05). Radyolojik değerlendirmelerde protezde yetmezlik veya lateral kompartmanda artrozda ilerleme gözlenmedi.

Çıkarımlar: Altmış yaş üstü ve obez hastalarda, hareketli taşıyıcılı Oxford Faz 3 UDP ile cerrahi tedavinin orta dönem sonuçları başarılıdır.

Mid-term results of Oxford Phase 3 unicompartmental knee arthroplasty in obese patients

Abstract

Objective: The aim of this study was to evaluate the mid-term outcomes of Oxford Phase 3 unicompartmental knee arthroplasty (UKA) in obese patients in terms of prosthesis survival, progression of lateral compartment arthrosis and functional outcomes.

Methods: The study included 67 patients, with a body mass index over 30, treated with mobile bearing Oxford Phase 3 UKA for isolated medial osteoarthritis between January 2005 and December 2010. Preoperative and postoperative knee range of motion (ROM) and knee scores (Hospital for Special Surgery, HSS and Oxford knee scores) were compared. Additionally, prostheses were evaluated using Oxford radiographic evaluation criteria at the final follow-up.

Results: Mean age was 61 years and mean follow-up was 67.5 months. Insert dislocation occurred in 3 patients (4.5%). Postoperative knee ROM, HSS and Oxford knee scores were significantly improved (p<0.05). There was no sign of prosthesis failure or lateral compartment arthrosis in radiographic evaluation at the final follow-up.

Conclusion: Oxford Phase 3 UKA with mobile bearing has good mid-term results in obese patients over 60 years of age.
