The Porous-Coated Anatomic Total Knee Experience. Special Emphasis on Complications and Wear

Research output: Contribution to journalArticle


One hundred sixty knees in 141 patients with the Primary Porous-Coated Anatomic prosthesis (Howmedica, Rutherford, NJ) were evaluated after a follow-up period of 5.6 years (range, 1–10 years). One hundred six knees were in the latest follow-up evaluation, including clinical examination and a defined standing radiograph with a follow-up period of 6.3 years (range, 3–10 years). Survivorship analysis regarding the cumulative revision rate (including completion with a patellar component) was 0.88 at the 8-year and 0.84 at the 10-year follow-up examination. The clinical result was satisfying/good, with a mean Hospital for Special Surgery score of 83 (range, 39–97). Five percent had thinning greater than 30% of the tibial component. The wear was calculated to be 1.0 mm (range, 0–9 mm), including three revised tibial components with heavy wear. Excluding the revised cases, the wear was 0.7 mm.
