Moreover, in this population, hip arthroscopy with labral repair results in greater risk of treatment failure than labral reconstruction. Subclinical degenerative changes to the labral tissue may be responsible for this finding. In my practice, however, labral reconstruction is generally reserved for scenarios such as a failed labral repair in the setting of poor tissue, labral hypoplasia/calcification in the primary setting ( less then 2 mm viable cuff of tissue), or complex irreparable tissue in the primary setting.One of the holy grails in orthopedics, and for medicine in general, is to have easy access to an immediately available and viable source of progenitor cells for use in tissue regeneration. The use of the term "mesenchymal stem cell" has been called into question, as it has historically represented a wide variety of tissue-specific cell types, only some of which can be categorized as true stem cells. More recent literature has better defined the characteristics of a stem cell, yet the landscape is still littered with unsubstantiated claims of cures for many human diseases, both within orthopaedic surgery as well as other fields of medicine. Although attention is needed to more carefully define the characteristics of the cells under investigation in any particular line of research, significantly more work will be involved to learn the biological mechanisms and signaling involved in coaxing these cells into in vivo tissue regeneration.Suture anchor technologies are constantly being innovated in the quest for improved stability, biological integration and clinical outcomes. However, the decision about the choice of suture-anchor materials remain elusive. There are some factors, including re
