Penelitian ini bertujuan untuk melihat adakah perbedaan intensitas nyeri, kekuatan otot, dan kemampuan fungsional lutut antara penderita obesitas dan tanpa obesitas dengan osteoartritis genu (OA genu). Dilakukan studi potong lintang pada 50 orang perempuan dewasa, terdiri dari 25 orang penderita obesitas dengan OA genu, dan 25 orang tanpa obesitas dengan OA genu yang datang ke poli unggulan Obesitas dan poliklinik muskuloskeletal Departemen Rehabilitasi Medik RSCM. Intensitas nyeri dinilai menggunakan metode Visual Analogue Scale (VAS), kekuatan otot kuadrisep diukur menggunakan dinamometer jinjing, sedangkan kemampuan fungsional lutut dievaluasi menggunakan indeks Laquesne. Hasil penelitian menunjukkan adanya perbedaan intensitas nyeri dan kekuatan otot kuadrisep, terutama antara obesitas derajat II dengan subjek yang memiliki berat badan normal, berat badan lebih maupun obesitas derajat I. Tidak terdapat perbedaan kemampuan fungsional lutut yang bermakna secara statistik antara penderita obesitas dan tanpa obesitas dengan OA genu.

The aim of the study was to find wheather there were any differences pain intensity, quadriceps muscle strength, and knee functional abilities between obese and non-obese patient with genu osteoarthritis (OA genu). We conducted a cross-sectional study in 50 adult women outward patient in Obesity Vlinic and Musculoskeletal Division of Physical Medicine and Rehabilitation Departement at Cipto Mangunkusumo Hospital, consisted of 25 obese people with osteoarthritis genu, and 25 non-obese people with osteoarthritis genu. The intensity of pain was assessed using the Visual Analogue Scale method (VAS), quadriceps strength was measured using a hand-held dynamometer, while functional ability was evaluated using the index Lequesne.

The study results showed that there were significant differences in pain intensity and quadriceps muscle strength, particularly between obese grade II and subjects with normal weight, overweight or obese first degree. There were no statistically significant difference in functional abilities knee between obese and non-obese patients with osteoarthritis genu.
