Abstract

The present study aimed to demonstrate the psychometric properties of the Turkish version of the Knee Society Score-Short Form in individuals before and after total knee arthroplasty. A prospective cross-sectional study was conducted with 112 participants (67 pre-operative, 45 post-operative). Participants were evaluated with Knee Society Score-Short Form, Visual Analog Scale (VAS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and Short Form-36 (SF-36) in the initial assessment. Forty-two participants refilled the Knee Society Score-Short Form one week later. Test-retest reliability and internal consistency of the Knee Society Score-Short Form (total score and items) were high (ICC: 0.84-0.96, α: 0.68-0.82). Knee Society Score-Short Form demonstrated a single factor in Exploratory Factor Analysis (EFA) (0.30-0.87). There was a high correlation between Knee Society Score-Short Form and WOMAC (r: -0.58, p<0.001). VAS (gait) and VAS (stairs or inclines) scores were moderately correlated with Knee Society Score-Short Form (r1: -0.39, r2: -0.49, p<0.001). Knee Society Score-Short Form was primarily associated (moderate to high) with social function (r: 0.57, p<0.001), physical function (r: -0.41, p<0.001), bodily pain (r: 0.45, p<0.001), general health (r: 0.43, p<0.001) and energy/vitality (r: 0.40, p<0.001) among the SF-36 subscores. Besides, ROC curve-based cut-off value, SEM and MDC of the Knee Society Score-Short Form were 52.5, 4.40 and 12.18, respectively. The Turkish version of the Knee Society Score-Short Form is a reliable and valid scale in older adults with total knee arthroplasty.

Özet

Bu çalışmanın amacı, total diz artroplastisi öncesi ve sonrası bireylerde Diz Cemiyeti-Kısa Form'un Türkçe versiyonunun psikometrik özelliklerini ortaya koymaktır. Prospektif kesitsel çalışma 112 katılımcı (67 ameliyat öncesi, 45 ameliyat sonrası) ile gerçekleştirilmiştir. Katılımcılar ilk değerlendirmede Diz Cemiyeti-Kısa Form, Görsel Analog Skala (GAS), Western Ontario ve McMaster Üniversiteleri Osteoartrit İndeksi (WOMAC) ve Kısa Form-36 (SF-36) ile değerlendirilmiştir. Kırk iki katılımcı bir hafta sonra Diz Cemiyeti-Kısa Formu tekrar doldurmuştur. Diz Cemiyeti-Kısa Formun (toplam puan ve maddeler) test-tekrar test güvenilirliği ve iç tutarlılığı yüksek bulunmuştur (ICC: 0,84-0,96, α: 0,68-0,82). Diz Cemiyeti-Kısa Form, Açıklayıcı Faktör Analizi'nde (AFA) tek bir faktör göstermiştir (0,30-0,87). Diz Cemiyeti-Kısa Form ile WOMAC arasında yüksek bir korelasyon vardı (r: -0,58, p<0,001). GAS (yürüme) ve GAS (merdiven veya eğim) skorları Diz Cemiyeti-Kısa Form ile orta düzeyde korelasyon göstermiştir (r1: -0,39, r2: -0,49, p<0,001). Diz Cemiyeti-Kısa Form, SF-36 alt skorlarından sosyal fonksiyon (r: 0,57, p<0,001), fiziksel fonksiyon (r: -0,41, p<0,001), bedensel ağrı (r: 0,45, p<0,001), genel sağlık (r: 0,43, p<0,001) ve enerji/canlılık (r: 0,40, p<0,001) ile öncelikli olarak ilişkiliydi (orta ila yüksek). Ayrıca, Diz Cemiyeti-Kısa Formun ROC eğrisine dayalı kesme değeri, SEM ve MDC sırasıyla 52,5, 4,40 ve 12,18 olarak bulunmuştur. Diz Cemiyeti-Kısa Form’un Türkçe versiyonu total diz artroplatisili yaşlı yetişkinlerde güvenilir ve geçerli bir ölçektir.
