Abstract :

Osteoarthritis is a condition that is often found in orthopedic cases. KOOS is a questionnaire to assess patient opinions about knee problems. 6–WMT is a simple clinical outcome measurement tool. This study aimed to discuss the relationship between subjective reference using KOOS questionnaire with objective reference using 6–WMT. This was a clinical trials study with cross–sectional design. The study was conducted at the Department of Surgery in the Division of Orthopedic Surgery at Haji Adam Malik Hospital in Medan and Pirngadi General Hospital in Medan. The sample of this study were all patients diagnosed with knee osteoarthritis from January to April 2019 who met the inclusion and exclusion criteria. The type of data collected in this study were primary data from questionnaires and secondary data obtained from medical records. Statistical analysis were carried out using the Pearson test using a significance level of 0.05 (α = 5%). A total of 53 samples were included in this study, consisted of 25 male patients (47.2%) and 28 female patients (52.8%). Age had a stronger correlation than the sports & recreation KOOS subscale (r = –0.475) and the weakest correlation with the KOOS subscales QoL (r = –0.384). While body weight and BMI had stronger correlation with the KOOS QoL subscale r = –0.499 and –0.419. In addition, body weight and BMI had the weakest correlation to ADL subscales, namely r = –0.371 and r = –0.281. For the 6–MWT parameter, a slightly higher positive correlation was seen in the sports & recreation KOOS subscale (r = 0.491); As for the pain subscale r = 0.382; symptoms of r = 0.402; ADL r = 0.432; and the last was the QoL subscale with r = 0.407. There was a negative relationship of the KOOS subscale on age, body weight, and body mass index. While the positive correlations were found on the KOOS subscale of the 6–MWT. While for the height, no correlation was found with the subscale of KOOS.
