Abstract Aim To compare foot joint kinetics and energetics in male paediatric boys with without blood‐induced ankle destruction to these of matched control groups. Methods A cross‐sectional study was conducted which 3D gait analysis data were collected from thirty‐five children (6‐21 years) severe or moderate haemophilia twenty‐six typically developing boys. Structural integrity the tarsal joints all haemophilic patients assessed using IPSG‐MRI scale. All participants walked barefoot while adopting a physiological pattern. Three subgroups created based on scores: group no involvement (HealthyHaemo), uni‐ bilaterally (PathoHaemo) only unilaterally (Haemo_Unilateral_Patho). Results The PathoHaemo presented significant lower Lisfranc peak dorsiflexion angular velocity (34.7°/s vs 71.4°/s, P = .000, Cohen d 1.31) significantly higher plantarflexion (−130.5°/s −51.8°/s, 0.98) compared group. Haemo_Unilateral_Patho side had Chopart Haemo_Unilateral_Healthy (41.7°/s 31.9°/s, .002, 1.16). Conclusion No evidence for mild deviations could be demonstrated. Internal moments, used as surrogate measure loading, quantified by multi‐segment model found similar within three subanalyses. We suggest that ongoing musculoskeletal development compensates structural damage joint.
