The aim of this master's thesis was to examine the entire rehabilitation process, analyze the postoperative consequences, and develop an evidence-based exercise protocol aimed at restoring motor function and mitigating the negative sequelae following complex surgical hip dislocation (SHD). Due to the intricacy of post-SHD rehabilitation and the absence of standardized guidelines, the study aimed to assess the impact of a structured rehabilitation program on hip muscle strength, joint mobility, postural stability, and gait pattern of the subject following SHD. The research is based on a case study of a 17-year-old female subject who participated in an eight-week exercise program six months after undergoing KDKS. The program was carried out three times per week and was structured based on comprehensive assessments, including isometric strength testing of the hip, trunk, and knee muscles; passive and active hip range of motion (ROM); static and dynamic balance assessments; gait analysis; and subjective outcome measures. Evaluations were conducted at baseline, at four weeks, and upon completion of the rehabilitation program. It was found that the exercise protocol increased hip strength in all measured movements compared to the baseline, most notably in hip adduction of the operated leg (+79.1%) and hip extension of the operated leg (+77.23%). Progress in both passive and active mobility was also evident in almost all movements, especially in passive internal rotation while lying on the back (+142.81%), passive hip abduction (+43.34%), and active internal rotation while lying on the back (+114.29%) of the operated leg. Postural control demonstrated greater improvements in dynamic compared to static balance, with the operated limb showing increased reach distances in the Y-balance test in the anterior (+27,94 %) and posterolateral (+16,48 %) directions. Gait analysis revealed enhanced step length symmetry and a 31,63 % reduction in Trendelenburg's sign, although residual deficits persisted. Video analysis of joint angles during single-leg landing revealed fewer compensatory patterns when regaining balance at the final measurement, with pelvic drop reduced by 47.54% and shoulder tilt reduced by 54.89%. The subjective perception of progress in performing daily tasks, assessed using the iHOT-33 questionnaire, was consistent with the objective improvements, particularly in symptoms and functional limitations (+7 points), and sports and recreational activities (+8 points). However, negative trends were observed in the work-related (-7 points) and psychosocial domains (-5 points). These findings underscore the effectiveness of a structured, progressive rehabilitation approach in enhancing muscle function, joint mobility, and neuromuscular control following SHD. Nonetheless, some functional limitations persist even after the program ends, indicating the need for a longer duration of training or earlier inclusion of the subject in the exercise program. Future studies should investigate the long-term outcomes of structured exercise interventions in a larger cohort to refine rehabilitation guidelines for this patient population.
