This study aims to examine how physiotherapists determine stretching intensity during knee flexion exercises in post-operative rehabilitation. It will also explore professional and clinical factors influencing these decisions, with the goal of informing standardized rehabilitation protocols.

This study aims to comprehensively evaluate the approaches of physiotherapists actively involved in post-operative knee rehabilitation in determining stretching intensity during knee flexion exercises. It also seeks to identify the professional and clinical factors influencing these decisions. By revealing the variations between physiotherapists' perceptions and their actual clinical practices regarding stretching intensity, the study aims to contribute to the development of standardized clinical protocols and enhance the specificity of existing rehabilitation guidelines.
