 Given the weakness of the literature on this subject Investigators opted for a trial randomization into 2 groups that will be made by the patient. The patient list will be balanced by randomly alternating blocks. the orthopedic ward staff and physiotherapists will not be informed of the first schedule to avoid a bias in the care of patients. An array of randomization will be created by an independent person in the study. This then randomly assign patients in both groups using Microsoft Excel.
