🎯
Objective & Hypothesis:Objectives: This study aims to investigate the long-termclinical outcomes, complications and survival rates of cementedOxford medial unicompartmental knee arthroplasty (UKA) andto compare the findings with the reported outcomes of UKA andtotal knee arthroplasty (TKA) in the literature.Patients and methods: In the study, 133 knees of 115patients (16 males, 99 females; mean age 65.5±8.3 years; range,50 to 88 years) who underwent Oxford medial UKA betweenMay 2007 and August 2013 were followed-up for an averageof 126 months.
📊
Key Findings & Data:While Kaplan-Meier method was used to evaluateimplant survival, Knee Society, Functional Knee Society andvisual analog scale scores were used for determining finalfunctional outcomes.Results: Totally 29 prosthetic complications (21.6% of totalpatients) were observed and the most common one was insertdislocation observed in 17 knees (12.6%).

Abstract

Objectives: This study aims to investigate the long-termclinical outcomes, complications and survival rates of cementedOxford medial unicompartmental knee arthroplasty (UKA) andto compare the findings with the reported outcomes of UKA andtotal knee arthroplasty (TKA) in the literature.Patients and methods: In the study, 133 knees of 115patients (16 males, 99 females; mean age 65.5±8.3 years; range,50 to 88 years) who underwent Oxford medial UKA betweenMay 2007 and August 2013 were followed-up for an averageof 126 months. Prosthetic complications and revisions wereevaluated. While Kaplan-Meier method was used to evaluateimplant survival, Knee Society, Functional Knee Society andvisual analog scale scores were used for determining finalfunctional outcomes.Results: Totally 29 prosthetic complications (21.6% of totalpatients) were observed and the most common one was insertdislocation observed in 17 knees (12.6%). Revision surgeries wereperformed for all of these patients. Among the 17 patients whounderwent insert replacement surgeries, the inserts were stable ineight during the follow-up while insert dislocation reoccurred innine. Revision surgeries were performed in a total of 21 patients(15.6%). There were statistically significant improvements in finalfollow-up functional knee scores of patients without complicationscompared to preoperative scores.Conclusion: According to our findings, while reoperationand early aseptic revision rates of Oxford medial UKA arehigh compared to the TKA results reported in the literature,functional results are satisfactory for patients with norevision.

Özet

Amaç: Bu çalışmada çimentolu Oxford medial unikompartmental diz artroplastisi (UDA)’nin uzun dönem klinik sonuçları, komplikasyonları ve sağkalım oranları araştırıldı ve bulgular UDA ve total diz artroplastisi (TDA)’nin literatürde bildirilen sonuçları ile karşılaştırıldı. Hastalar ve yöntemler: Çalışmada Mayıs 2007-Ağustos 2013 tarihleri arasında Oxford medial UDA uygulanan 115 hastanın (16 erkek, 99 kadın; ort. yaş 65.5±8.3 yıl; dağılım, 50-88 yıl) 133 dizi ortalama 126 ay takip edildi. Protez komplikasyonları ve revizyonları değerlendirildi. İmplant sağkalımını değerlendirmek için Kaplan-Meier yöntemi kullanılırken son fonksiyonel sonuçları belirlemek için Diz Derneği, Fonksiyonel Diz Derneği ve görsel analog ölçeği skorları kullanıldı. Bulgular: Toplam 29 protez komplikasyonu (toplam hastaların %21.6'sı) gözlendi ve en yaygın olanı 17 dizde (%12.6) görülen insert çıkığıydı. Tüm bu hastalara revizyon cerrahisi yapıldı. Insert replasman cerrahisi uygulanan 17 hastadan sekizinde t akipte i nsert stabil i ken, dokuzunda tekrar insert çıkığı gelişti. Toplamda 21 hastaya (%15.6) revizyon cerrahisi yapıldı. Komplikasyon olmayan hastaların son takip fonksiyonel diz skorlarında ameliyat öncesi skorlara göre istatistiksel olarak anlamlı iyileşme vardı. Sonuç: Bulgularımıza göre, Oxford medial UDA'nın literatürde bildirilen TDA sonuçlarına göre yeniden ameliyat ve erken aseptik revizyon oranları yüksek olmakla beraber fonksiyonel sonuçlar revizyonu olmayan hastalar için tatmin edici idi.
