Proprioception could be defined as the perception of limb position in the space. In last few decades, extensive research has been conducted, dedicated to the sensory role of anterior cruciate ligament and to the analysis of how its damage influences knee joint function. Even though knee proprioception is a widely studied topic, we still do not understand exactly the role of intact and injured anterior cruciate ligament in proprioception and what factors affect proprioceptive rehabilitation after anterior cruciate ligament reconstruction. The aim of this paper is to synthesize the theoretical framework of knee proprioception and the sensory role of anterior cruciate ligament. This study can be viewed as providing a theoretical foundation for a very complex research question
