Objectives The aim of this study was to assess the quality of life (QoL) in patients with primary knee osteoarthritis (OA). Background OA is the most common degenerative joint disorder and a major public health problem worldwide. OA of the knee is a major cause of mobility impairment, which has an unpredictable and negative impact on health and QoL. Patients and methods This was a cross-sectional analytical study involving 116 patients with primary knee OA, who were admitted to the outpatient clinic of rheumatology and orthopedics in Menoufia University Hospital during the period of the study. Patients were included if they had radiographic evidence of hip or knee OA. QoL in these patients was assessed using the OAKHQOL questionnaire, which includes 43 items and describes QoL in five domains: physical activities (16 items), mental health (13 items), pain (four items), social support (four items), social functioning (three items), and three independent items. Each item is scored on a scale from 0 to 10. Results This cross-sectional study was carried out on 116 of patients with primary knee OA; 74.1% of these patients were women and 25.9% were men. The mean age of the studied population was 51.37 ± 8.85 years. For the KHOAQOL score, a statistically significant correlation was reported with the duration of the disease. Age, sex, BMI, site of OA, and regular use of drug showed no statistically significant difference in their KHOAQOL score. This study found a significant positive correlation of BMI of patients and their physical activity parameter of KHOAQOL. Conclusion The perception of QoL is affected negatively by the duration of the disease, whereas age, sex, site if disease unilateral or bilateral, and socioeconomic status showed no significant correlation. The study also reported that performing daily physical activity is affected by the BMI of the patient.
