The Correlation Between the Cumulative Illness Rating Scale and the Knee Injury and Osteoarthritis Outcome Score in Knee Osteoarthritis Patients

Objective: This research aimed to explore the correlation between Cumulative Illness Rating Scale (CIRS) and physical disability among individuals suffering from symptomatic knee osteoarthritis (OA). Materials and Methods:In this cross-sectional study, 89 individuals diagnosed with knee OA were enrolled.The severity of OA was assessed radiologically using the Kellgren-Lawrence staging method.The Knee Injury and OA Outcome Score was utilized to assess pain intensity, symptoms, daily functional capacity, engagement in sports/recreation, and knee-related quality of life (QoL).The CIRS scores for all participants were calculated by the same researcher.Throughout this process, both the Kellgren-Lawrence staging and CIRS calculations were overseen by the same researcher to maintain consistency.Results: Seventy patients (78.7%) were female.19 were male (21.3%).The mean age was 56.8 years.The mean body mass index was 30.1kg/m.Knee OA was bilateral in 81 patients (91.1%).The radiological severity of knee OA was stage II or III in 73 subjects (82.02 %).The mean Knee Injury and OA Outcome Score pain severity, symptoms, activities of daily living, sport/recreation, and knee-related QoL scores were 55. 4, 19.05, 59.8, 34.2, and 54.7, respectively.A significant correlation was observed between CIRS score, and KOOS Symptoms and KOOS QoL (p<0.05). Conclusion:In this study, there was a significant relationship between the number of comorbid diseases of the patients and their knee-related QoL.
