Hip resurfacing arthroplasty (HRA) is reconstructive surgery of the surfaces of the femur and acetabulum. It’s relatively new in the USA (approved by the FDA in 2006) but has been very successfully done in Europe and Australia for over a generation.
Talk to your surgeon about this alternative to hip replacement. If he does not know about it or does not perform it, seek a second opinion, especially if you are younger (under 60), active, and in otherwise excellent health. (TIP: If the surgeon is demanding that hip replacement is your only option, find another surgeon.)
Dr. Stephan Kreuzer demonstrates his method of the direct anterior approach to HRA, also known as Birmingham Hip Resurfacing, in this edited video (2009):
