The above article, published online on 2 March 2015 in Wiley Online Library (wileyonlinelibrary.com), has been retracted by agreement between the journal Editor-in-Chief, Edward M. Schwarz; the Orthopaedic Research Society; and Wiley Periodicals LLC. The retraction has been agreed due to concerns raised by third parties. Specifically, a duplication has been identified within Figure 3, and image elements in Figures 3 and 4A were found to have been previously published by the author group in different scientific contexts. The clarification provided by the authors was found to be insufficient to address the concerns. Furthermore, additional scientific inconsistencies have been identified. Accordingly, the article has been retracted as the editors consider its results and conclusions to be invalid. The authors have been informed of the retraction decision. The corresponding author, Lei Wei, stated that the concerns had been partially addressed. However, due to the unavailability of the co-author responsible for the experiments affected by the unresolved issues, the experiments could not be readily repeated. Co-author Qian Chen agreed with the decision to retract the article, noting that their contribution was limited to providing reagents and therefore did not meet the criteria for authorship. No response was received from the remaining co-authors.
