The subjects were divided into a group in which osteolysis occurred and a group in which osteolysis did not occur and retrospectively compared and analyzed. Knee Society Knee Score and Function Score, preoperative and postoperative range of motion (ROM), femoral and tibial implant positions, preoperative and postoperative femerotibial angles, posterior femoral condylar offset (PCO), level of joint line (JL), and posterior tibial slopes were measured and clinically and radiologically compared.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Osteolysis occurred in 28\u00a0knee joints (5.7 %). No significant difference was observed between the patient group without osteolysis, and the patient group with osteolysis was observed in preoperative and postoperative ROM, femoral and tibial implant positions, or preoperative and postoperative femerotibial angles. The means of preoperative and postoperative differences in PCO and level of JL were significantly larger in the patient group with osteolysis than in the patient group without osteolysis (<jats:italic>p<\/jats:italic> = 0.01, <jats:italic>p<\/jats:italic> = 0.007), and regression analyses showed that the means of preoperative and postoperative differences in these two variables were related with the occurrence of osteolysis (<jats:italic>p<\/jats:italic> = 0.021, <jats:italic>p<\/jats:italic> = 0.018).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The present study shows that biomechanical changes occurring after TKA are related with the occurrence of osteolysis. For clinical relevance, surgeons should pay great attention to restore normal anatomical structure as much as possible with careful preoperative plans, accurate surgical techniques, and selection of appropriate implants.<\/jats:p><\/jats:sec><jats:sec><jats:title>Level of evidence<\/jats:title><jats:p>Retrospective comparative study, Level III.<\/jats:p><\/jats:sec>","DOI":"10.1007\/s00167-014-3088-0","type":"journal-article","created":{"date-parts":[[2014,6,10]],"date-time":"2014-06-10T19:33:10Z","timestamp":1402428790000},"page":"1863-1869","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Factors affecting the osteolysis around the components after posterior\u2010stabilized total knee replacement arthroplasty"],"prefix":"10.1002","volume":"23","author":[{"given":"Chang Wan","family":"Kim","sequence":"first","affiliation":[{"name":"Department of Orthopedic Surgery Busan Paik Hospital College of Medicine Inje University 633\u2010166 Gaegeum\u2010dong, Busan Jin\u2010gu 614\u2010735 Busan South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Seung Suk","family":"Seo","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery Bumin Hospital 380\u20104 Deokcheon 1\u2010dong, Buk\u2010gu 616\u2010819 Busan South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jung Han","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery Busan Paik Hospital College of Medicine Inje University 633\u2010166 Gaegeum\u2010dong, Busan Jin\u2010gu 614\u2010735 Busan South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hyeong Joo","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery Busan Paik Hospital College of Medicine Inje University 633\u2010166 Gaegeum\u2010dong, Busan Jin\u2010gu 614\u2010735 Busan South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chang Rack","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery Busan Paik Hospital College of Medicine Inje University 633\u2010166 Gaegeum\u2010dong, Busan Jin\u2010gu 614\u2010735 Busan South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2014,6,11]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.knee.2009.11.001"},{"key":"e_1_2_6_3_1","first-page":"147","article-title":"New Jersy low contact stress knee replacement system.
