Intramedullary nailing of tibial fractures and 1-year development in gait function. Gait asymmetry is common after the first 6 months post-operatively. Gait asymmetry becomes normalized between 6 and 12 months post-operatively. Weak associations between gait asymmetry and patient-reported HRQOL were observed. Regaining pre-injured gait function after a tibial fracture is a prolonged process.
