The length of stay depends not only on factors such as early mobilization, pain management, major or minor complications and logistical or organizational problems (1) (2). It also depends on the availability of adequate services when the patient needs to be transferred to an appropriate facility. Each of these steps can be further developed in order to improve the quality of care for patients, reduce hospital costs and increase the availability of beds (3). As a result, the reduction in average length of stay would not only result in a reduction in cost but also a greater turnover in the number of patients. Several studies show that the application of a post-operative fast-track strategy may reduce the length of stay in a very significant manner with benefit for patients and hospitals (3).Thus, if their condition allows, patients would have rapid post-operative rehabilitation, with early joint mobilization at D0 (operative day) and walking from D1 (the first post-operative day).
