Correlation of Self-Reported Questionnaire (KOOS) with Some Objective Measures in Primary OA Knee Patients

Abstract

Purpose. Objective of the present study was to see the correlation of subjectively measured KOOS questionnaire with objectively measured 6-minute walk test (6-MWT), age, height, weight, and BMI. Participants. 251 subjects with OA knee based on American College of Rheumatology criteria. Methods. After passing inclusion and exclusion criteria, the following parameters were recorded: age, height, weight, and BMI. Then subjects were asked to fill KOOS questionnaire; then all subjects were asked to do self-paced walk for 6 minutes. Analysis. Spearman rank test was done to see the correlation. Significant level was set at P < 0.05. Results. 6-MWT had a weak correlation with KOOS-ADL (rho 0.461) and strong correlation with KOOS-symptom, KOOS-pain, and KOOS-sports and very strong correlation with KOOS-QOL. BMI had a strong correlation with KOOS-pain, KOOS-symptom, KOOS-ADL, and KOOS-sports and very strong correlation with KOOS-QOL. Weight had a weak correlation with KOOS-symptom, KOOS-ADL, and KOOS-sports and strong correlation with KOOS-pain and KOOS-QOL. All the above values were significant with P < 0.001. Conclusion. KOOS is strongly positively correlated with 6-MWT and negatively correlated with BMI. Its correlation strength has decreased with weight.

Health-related quality of life in Egyptian patients with knee osteoarthritis: correlation with performance-related measures

“…Similar to the results of our study, Sivachidambaram et al [14] correlated self-reported questionnaire (KOOS) with some objective measures in primary OA knee patients and found that KOOS has almost no correlation with age.…”

“…Moreover, Sivachidambaram et al [14] correlated selfreported questionnaire (KOOS) with some objective measures in primary OA knee patients and found that all KOOS subtypes have a significant correlation with 6-MWT. 6-MWT had a weak correlation with KOOS-ADL (=0.461) and a strong correlation with KOOS symptom, KOOS-pain, and KOOSsports (=0.578, 0.619, and 0.536, respectively) and a very strong correlation with KOOS-quality of life (=0.733) [14].…”

Reliability, Validity, and Responsiveness of the Chinese Version of the Knee Injury and Osteoarthritis Outcome Score (KOOS) in Patients with Anterior Cruciate Ligament Reconstruction in Mainland China

“…Fortunately, many patient-reported measurement tools are available for evaluating knee-related disabilities and postoperation quality of life. One patient-reported outcome tool is the Knee injury and Osteoarthritis Outcome Score (KOOS) measurement tool that provides subjective information about the disease process without examiner bias [1,2].…”

Mid-term evaluation of clinical and functional outcomes after arthroscopic medial longitudinal and bucket-handle meniscus repair

“…Preoperative and final follow-up Lysholm Knee Score (LKS), International Knee Documentation Committee (IKDC) score, Tegner Activity Scale (TAS) score, and Knee Injury and Osteoarthritis Outcome Score (KOOS) were used for functional evaluation between longitudinal and bucket-handle tears.
