Hip instability continues to be a challenge in hip preservation. Our understanding of the role of osseous anatomy, labral integrity and soft-tissue stabilizers has increased dramatically over the past several decades. Connective-tissue disorders such as Ehlers-Danlos syndrome pose a significant challenge to the management of instability in all joints but particularly in the hip. Ligamentum teres tears have been found to be more common than previously thought, although their significance is still not well understood. In patients with both Ehlers-Danlos syndrome and ligamentum teres tears, reconstruction and capsular plication result in moderate success, but not in all cases.
