Abstract
- This study assessed the 15-year minimum outcomes of the RingLoc cup (Zimmer Biomet, Warsaw, Indiana), a second-generation cementless porous plasma-coated acetabular component. The study identified 2438 patients (2905 hips) who underwent total hip arthroplasty using the RingLoc acetabular component between 1992 and 2000. Fifteen-year minimum follow-up data were available on 431 consented patients (511 hips). Clinical outcomes included the Harris hip score. Follow-up radiographs, complications, and revisions were reviewed. Mean follow-up was 18.2 years (range, 15-24.7). Harris hip scores improved from 46.9 preoperatively to 79.3 postoperatively (p < .001). Reoperation for any reason was performed in 141 hips (27.6%). Isolated liner exchange was performed in 96 hips (18.8%) and acetabular revisions were performed in 44 hips (8.6%). Acetabular survivorship at 15 years was 93.5% for all causes and 94.3% for aseptic revision. This study demonstrated excellent acetabular survivorship of the porous plasma-sprayed RingLoc cup at a minimum 15-year follow-up. (Journal of Surgical Orthopaedic Advances 28(1):31-34, 2019).
