This paper reviews the psychological responses to athletic injuries and their impact on rehabilitation outcomes. Athletes' mental states, influenced by stress, motivation, self-efficacy, and social support, are critical to recovery. Emotional responses such as anxiety, depression, and fears of reinjury are particularly common among competitive athletes and those experiencing long-term or recurrent injuries, highlighting the need for psychological support alongside physical care. Grounded in stress and coping, social cognitive, and self-determination theories, this review explores how resilience, adaptive coping strategies, and self-efficacy promote successful recovery. Social support from coaches, teammates, family, and healthcare professionals is emphasized as essential for managing stress and sustaining athlete engagement. Practical approaches, including goal-setting, relaxation techniques, and open communication, are identified as effective tools for addressing psychological challenges and improving adherence to rehabilitation protocols. Tailored interventions that consider individual needs ensure better recovery outcomes and long-term well-being. The findings underscore the importance of integrating psychological strategies into rehabilitation programs. Addressing both mental and physical aspects of recovery enables athletes to overcome emotional barriers, build resilience, and achieve a sustainable return to sport and daily life.
