Hubungan antara Karakteristik Gambaran Radiologi Osteoartritis Lutut dengan Skor WOMAC di Rumah Sakit Siti Khodijah Sepanjang Sidoarjo

Latar Belakang: Osteoartritis lutut merupakan penyakit degenratif sendi yang sering menyebabkan nyeri, kekauan, dan keterbatasan fungsi, terutama pada populasi usia lanjut. Penyakit ini menjadi salah satu penyebab utama disabilitas yang berdampak pada penurunan kualitas hiudp serta peningkatan beban kesehatan masyarakat. Gambaran radiologis yang dapat ditemukan seperti penyempitan celah sendi, osteofit, sklerosis subkondral, dan subluksasi diduga berhubungan dengan kondisi klinis pasien. Namun, hubungan masing-masing temuan radiologis dengan skor WOMAC masih menunjukkan hasil yang bervariasi. Tujuan: Mengetahui hubungan antara karakteristik gambaran radiologi dengan skor WOMAC pada pasien osteoartritis lutut. Metode: Penelitian ini menggunakan metode analitik observasional dengan desain cross-sectional pada 43 responden dengan osteoartritis lutut yang dipilih menggunakan teknik purposive sampling. Data temuan radiologi diperoleh dari foto X-Ray lutut, sedangkan skor WOMAC diperoleh melalui pengisian kuesioner WOMAC. Analisis data dilakukan menggunakan uji korelasi Spearman. Hasil: Mayoritas responden berusia 60-69 tahun dan berjenis kelamin perempuan. Hasil analisa data menunjukkan terdapat hubungan signifikan antara penyempitan celah sendi (r=0,582; p<0,001), osteofit (r=0,328; p=0,032), dan subluksasi (r=0,323; p-0,035) dengan skor WOMAC. Sementara itu, sklerosis subkondral secara statistik tidak menunjukkan hubungan yang bermakna (r=0,233; p=0,132). Kesimpulan: Penyempitan celah sendi, osteofit, dan subluksasi berhubungan dengan skor WOMAC pada osteoartritis lutut, sedangkan sklerosis subkondral tidak menunjukkan hubungan yang bermakna.

Background: Knee osteoarthritis is a degenerative joint disease that commonly causes pain, stiffness, and functional limitation, particularly among adults. It is recognized as one of the leading causes of disability among older adults, contributing substantially to impaired quality of life and increased healthcare utilization. Radiographic features of knee osteoarthritis, including joint space narrowing, osteophytes, subchondral sclerosis, and subluxation are thought to be associated with clinical condition. However, the relationship between individual radiographic features and WOMAC scores remains inconsistent across previous studies. Objective: To determine the association between radiographic characteristics and WOMAC scores in patient with knee osteoarthritis. Methods: This analytical observational study used a cross-sectional design involving 43 patients with knee osteoarthritis selected through purposive sampling. Radiographic characteristic were assessed using knee X-Ray imaging while WOMAC scores were obtained through the WOMAC questionnaire. Data were analyzed using Spearman correlation test. Result: Most participant were female and aged 60-69 years. Significant correlation were found between joint space narrowing (r=0.582; p<0.001), osteophytes (r=0.328; p=0.032), and subluxation (r=0.323; p=0.035) with WOMAC scores. In contrast, subchondral sclerosis was not statistically significant correlation with WOMAC scores (r=0.233; p=0.132). Conclusion: Joint space narrowing, osteophytes, and subluxation were associated with WOMAC scores in patient with knee osteoarthritis, whereas subchondral sclerosis showed no statistically significant association.
