The XXXX : a 19- to 25-year follow-up study.

@entity1 @entity691 @entity174 @entity281 @entity572 @entity2096
The goal of this study was to evaluate the long-term survivorship of primary @entity572 (THA) using Harris-Galante porous I acetabular and @entity2096 . From July 1985 to December 1991, we performed primary cementless THA on 76 hips (70 @entity1 ). Twenty-nine @entity1 (31 hips) died due to causes unrelated to the THA, and 6 @entity1 (7 hips) were lost to follow-up. Of 76 hips (70 @entity1 ) studied, 38 hips (35 @entity1 ) were available for follow-up at a mean 22.5 years (range, 19-25 years) postoperatively. Mean @entity1 age at index procedure was 51.2 years (range, 42-65 years). Average Harris Hip Score was 40.5 points preoperatively and 85.8 points at final follow-up. No @entity1 had an early or late postoperative deep @entity281 . Radiographically, the acetabular component fixation was stable in all 38 hips. The femoral component was bone-ingrown in 26 hips, stable-fibrous in 10, and unstable in 2. One unstable hip required revision of the femoral component. Dissociation of the @entity691 liner occurred in 3 hips without @entity174 of the metal locking tines and required revision of the @entity691 liner and the articular head. A total of 4 hips had documented revision, and 1 femoral component failed radiographically. The survival rate with the endpoint defined as revision surgery and radiographic loosening was 86.8% at 22.5 years of follow-up. Mean @entity691 wear was 0.085 mm/year (range, 0.031-0.15 mm). This study found that the Harris-Galante porous I acetabular and @entity2096 produce excellent long-term results.
