A well-known and long-term complication of developmental dysplasia of the hip (DDH) is improper gait pattern, early regressive joint disorder, and permanent pain. It can affect the family's psychological, social, and functional parts. This study planned to resolve foot posture and gait analysis across patients with developmental hip dysplasia and correlate it with the control group. Case-control studies determine the main results. We correlated the gait analysis results on the Zebris FDM platform. The case included candidates with DDH under conservative treatment with an abduction brace and a control group with healthy participants. This study was conducted at King Abdullah Specialized Children Hospital, Riyadh, in the Kingdom of Saudi Arabia. This research enclosed 445 outcomes with DDH and 168 for the control category. The Sign test presented a significant diversity in Zebris FDM outcomes between DDH and the control group, especially in left foot external rotation with a p-value of 0.01 (left hip mean of 4.53, n=445, SD 8.78). A significant variation was present in step width, stance phase on both legs, single support, load response, swing phase, pre-swing, and a double support p-value of 0.00 (p<0.05). W-sitting was preferred in 256 (n=445, 58%) of the DDH results and by 61 (n=168, 36%) from the control group. This study's outcomes presented a greater risk of pronation on the left foot and gait alteration on the right lower limb. The gait investigation presented a clear description of its patterns in paediatrics with DDH. Analyzing the gait among the DDH and the control group demonstrated a variation in each gait outcome from Zebris FDM platform software. DDH has a negative response on the gait pattern and foot posture, this is a great consequence presented in connection with Saudi applicants.
