The most favorable mechanical environment for the hip is one that is free of both instability and impingement, creating a concentric articulation with optimum femoral head coverage by the acetabulum. Anatomic variations such as acetabular dysplasia with associated instability, and femoroacetabular impingement with abnormal constraint, will lead to abnormal joint mechanics, articular damage, and osteoarthritis. Surgical techniques such as periacetabular osteotomies, and femoral and acetabular osteoplasties enable correction of anatomic variations that cause mechanical damage to the hip joint, thereby potentially preventing or delaying development of osteoarthritis and subsequent need for joint replacement.
髋关节最理想的力学环境是既没有不稳定也没有撞击，同时实现股骨头与髋臼的同心覆盖，达到最佳的关节吻合。髋臼发育不良伴相关不稳定和股骨髋臼撞击伴异常约束等解剖变异会导致关节力学异常、关节损伤和骨关节炎。髋臼周围截骨术、股骨和髋臼骨成形术等手术技术可以纠正导致髋关节力学损伤的解剖变异，从而有可能预防或延迟骨关节炎的发展和随后对关节置换的需求。
