Hip preservation surgery—Can we change the natural history of osteoarthritis?

Structural abnormalities of the hip including developmental dysplasia (DDH) and femoroacetabular impingement (FAI) are a predominant cause of primary osteoarthritis. While affected patients may have significant pain and functional limitations, many may remain asymptomatic and will likely incur intra-articular damage over time. The objective of this review is to explore the natural history of DDH, FAI, and the current outcomes of hip preservation surgery including peri-acetabular osteotomy, hip arthroscopy, and surgical hip dislocation.
