This article strictly defines the area of cup placement based on data from 185 healthy hip centers and Ranawat's triangle. Linear wear rate (LWR) was measured in 55 total hip arthroplasty (THA) cases and categorized as low or high. The relationships between these categories and cup size, inclination, anteversion, position, age, follow-up period, bone graft, cup osteolysis, and stem osteolysis were investigated.<\/jats:p>","DOI":"10.3928\/01477447-20080301-19","type":"journal-article","created":{"date-parts":[[2009,3,12]],"date-time":"2009-03-12T16:29:59Z","timestamp":1236875399000},"page":"1-7","source":"Crossref","is-referenced-by-count":6,"title":["Effect of Cup Placement on Polyethylene Wear Rate in Cementless Total Hip Arthroplasty"],"prefix":"10.3928","volume":"31","author":[{"given":"Masayuki","family":"Ito","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kunihiko","family":"Tokunaga","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Naoto","family":"Endo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuhichi","family":"Takano","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nobuhiro","family":"Yuasa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2308","reference":[{"issue":"72","key":"e_1_3_1_2_2","first-page":"7","article-title":"Total hip replacement by low-friction arthroplasty","author":"Charnley J","year":"1970","unstructured":"Charnley J.
