A multicenter retrospective review was performed analyzing 1081 primary total hip replacements in 944 @entity1 using the Harris Galante-I cementless acetabular component with screw fixation. All @entity1 were followed up for a minimum of 5 years with a mean followup of 81 months. Linear @entity691 wear averaged 0.11 mm/year (range, 0-0.86 mm/year). @entity530 was seen in 25 @entity1 (2.3%). Migration of the acetabular component was seen in four hips. A subgroup of @entity1 was reanalyzed at a minimum followup of 10 years. The mean linear @entity691 wear rate remained 0.11 mm/year. In this group, only one socket had migrated. There was an association between wear rate and age. On average, younger @entity1 had higher wear rates. The risk for having @entity530 develop and the need for revision surgery also was age-related. Twenty-two percent of hip replacements (15 hips) in @entity1 younger than 50 years of age at the time of their index operation had @entity530 develop. In contrast, for @entity1 older than 50 years of age at the time of surgery only 7.8% (eight hips) had @entity3061 of the pelvis develop. For @entity1 older than 70 years of age at the time of primary total hip replacement, none had @entity530 develop.
