The Harris-Galante total hip arthroplasty - A minimum 8-year follow-up study

A total of 93 Harris-Galante Porous I (HGP-1) prostheses were analyzed with a mean follow-up of 10.2 years. Thigh pain (28 hips) correlated With unsta ble fixation (P<.005), female gender (P<.045), Young age (P<.05), poor dist al femoral fill (P<.002), subsidence (P<.0001), and osteolysis (P<.05). Thi rteen stems and 6 metallic shell cups were revised. Kaplan-Meier analysis s howed 13-year survival rates of 92.5% +/- 5.8% for the metallic shell cup, 79.7% +/- 13% for the HGP-I cup, and 76.3% +/- 14.0% for the stem. Five pol yethylene liners were changed because of wear >1 mm. Radiographic loosening occurred in 8 cups. Radiographic bone ingrowth was present in 54 stems, st able fibrous fixation Was present in 24 stems, and unstable fixation was pr esent in 15 stems. The mean polyethylene wear was 0.17 mm/y. Eleven hips (1 1.8%) had acetabular osteolysis, and 24 (25.8%) had femoral osteolysis, the latter being more frequent in unstable stems (P<.007). The HGP-I metallic cup shows better clinical and radiographic results than the stem, which fre quently is associated with pain, unstable fixation, and osteolysis. Excessi ve polyethylene wear is frequent.
