Osteoarthritis adalah penyakit musculoskeletal kronis progresif dan degenratif, untuk mendiagnosis oa diperlukan modalitas foto rontgent genu dengan posisi berdiri. mechanical axis angle merupakan salah satu pengukuran untuk menilai keselarasan ekstermitas bawah pada pasien. tatalaksana non bedah pada oa adalah nsaid yang jika digunakan secara terus menerus pada pasien khususnya lansia, maka akan memperburuk kualitas hidup mereka. terapi pembedahan pada oa yaitu total knee replacement yang dilaporkan tingkat kesuksesan mencapai 90%. penelitian ini bertujuan untuk menilai apakah ada hubungan antara perubahan maa terhadap quality of life pada pasien oa yang telah menjalani operasi tkr di rsud dr. zainoel abidin. jenis penelitian ini adalah analitik observasional dengan metode cross-sectional. teknik sampling pada penelitian ini adalah total sampling. sampel penelitian ini adalah pasien yang terdiagnosis oa yang telah menjalani operasi tkr di rsudza tahun 2021-2022. data yang diambil meliputi data demografi dan hasil pemeriksaan imaging, lalu disajikan dalam bentuk tabel distribusi frekuensi. hasil penelitian terdapat 30 subjek, dengan jenis kelamin terbanyak ialah perempuan (66,7%), dengan usia terbanyak yaitu lansia akhir (>56 tahun) yaitu sebanyak (76,67%). berdasarkan pengukuran mechanical axis angle, genu varus lebih dominan (53,33%) dibandingkan genu valgus (26,67%). dari uji spearman’s rho menunjukkan nilai p-value sebesar 0,045 dengan koefisien korelasi sebesar 0,368 maka dapat disimpulkan bahwa hubungan antara perubahan gambaran radiologi mechanical axis angle dan quality of life pasien tergolong dalam hubungan lemah. kata kunci : osteoarthritis, mechanical axis angle, quality of life, total knee replacement

Osteoarthritis is a chronic, progressive and degenerative musculoskeletal disease. To diagnose OA, genu x-rays are required in a standing position. Mechanical Axis Angle is one of the measurements to assess the alignment of the patient's lower extremities. Non-surgical treatment for OA is NSAIDs which, if used continuously in patients, especially the elderly, will worsen their quality of life. Surgical therapy for OA is Total Knee Replacement which has a reported success rate of up to 90%. This study aims to assess whether there is a relationship between changes in MAA and Quality of Life in OA patients who have undergone TKR surgery at RSUD Dr. Zainoel Abidin. This type of research is observational analytic with a cross-sectional method. The sampling technique in this research is Total Sampling. The sample for this study were patients diagnosed with OA who had undergone TKR surgery at RSUDZA in 2021-2022. The data taken includes demographic data and imaging examination results, then presented in the form of a frequency distribution table. The results of the research were 30 subjects, with the largest gender being female (66.7%), with the largest age being late elderly (> 56 years), namely (76.67%). Based on Mechanical Axis Angle measurements, genu Varus is more dominant (53.33%) than genu valgus (26.67%). The research results related to changes in MAA were 2 and 3 degrees (13.33%), based on the correlation coefficient value, it was found that the correlation coefficient was 0.368, meaning that the close relationship between changes in the Mechanical Axis Angle radiological image and the patient's Quality of Life was classified as a weak relationship.
