Cementless total hip arthroplasty: femoral remodeling and clinical experience

Cementless fixation of arthroplasty components has proved to be viable. The physiology of ingrowth is increasingly understood, and many of the factors influencing this phenomenon have been elucidated. The effect of ingrowth fixation on bone remodeling is less understood. The effects of varying ingrowth surfaces and the distribution of these surfaces influence remodeling and are critical to clinical success. Clinical studies with femoral components of different design show that while both yield good clinical results and exhibit similar remodeling patterns, the degree of remodeling may be influenced by design criteria.
