Commitment and Psychological issues Vinícius Ynoe Moraes, Federal University of São Paulo 25 March 2010 This is a very interesting paper regarding to post-operative issues after hip resurfacing. It is a fact that not only the surgical technique and surgeon's skills are isolated factors influencing rehabilitation outcomes. We would like to share our data with the authors and other readers. We have delevoped a cross-sectional study regarding to identify - on an orthopedic ward population - which are the patients that would be prone to develop anxiety or depression on the wards. We have found that the patients who were submitted arthroplasties (knee and Hip) were more prone to develop anxious status, as somewhat as pointed by this study, showing that the patients whose had more vigorous mental status were well suceeded on rehabilitation. Comparing this paper data, it is possible that promoting preventative out-of-hospital improvement of mental status, and as a quick intervention an in-ward psychological support would even make our outcomes even better. Warm regards, and once again congratulations for the research. Dr. Vinícius Ynoe de Moraes, M.D. References: de Moraes VY, Jorge MR, Faloppa F, Belloti JC.
