Impact of end-stage knee osteoarthritis on perceived physical function and quality of life: A descriptive study from Jordan.

End-stage knee OA negatively impact the patients' perceived function and quality of life. Patients' KOOS scores were similar to those reported in other countries, with QoL being the domain most affected. Our findings demonstrate that the level of knee pain has a determinant effect on our patients' perceptions of functional abilities and QoL. As waiting-list patients, addressing knee pain with a targeted regimen prior to TKA, as well as increasing patient's awareness about knee pain management, may improve/ or minimize deterioration in perceived functional ability and QoL while awaiting TKA.
