Limitations
This study focused on early knee function in patients who underwent ACL reconstruction, and its long-term impact remains to be further investigated. Owing to the late opening of the browsing record collection function, the Mhealth platform's usage record is not yet complete, so further evaluation of the patients' usage will be considered in the next step. Mhealth intervention requires patients to learn to use smartphones and corresponding software, so promotion has certain limitations. Considering this factor, in the later stage, you can consider adding an education column for caregivers in the mHealth platform and implementing interventions by intervening with caregivers.
