Knee Orthopedic Outcome Score- Patellofemoral, Patellofemoral Pain, Patient-reported Outcome Measures, Reliability Test of Malay Version


Introduction: The Knee Orthopaedic Outcome Score- Patellofemoral (KOOS-PF) has been established as a reliable and valid instrument for evaluating individuals suffering from patellofemoral discomfort. However, a Malay version of KOOS-PF is unavailable. Significant: To assess the reliability of the KOOS-PF Malay version. Methods: The English KOOS-PF was translated into Malay utilising a forward and backward translation technique. Findings: The Cronbach's alpha value is 0.917, indicating highly reliable tools for Malaysians with PFPS. Conclusion: The KOOS-PF Malay questionnaire was reliable, dependable, and simple for assessing stiffness, pain, and quality of life in Malaysia.
