The mean follow-up period was 3.25 years (3.1 to 3.5). The aspect ratios of the standard and gender-specific prostheses were compared with that of the distal femur. <\/jats:p><jats:p> The mean post-operative Knee Society knee scores were 94 (70 to 100) and 93 (70 to 100) points and the function scores were 83 (60 to 100) and 84 (60 to 100) points for the standard implants and the gender-specific designs, respectively. The mean post-operative Western Ontario and McMaster Universities score was 26.4 points (0 to 76). Patient satisfaction, the radiological results and the complication rates were similar in the two groups. In those with a standard prosthesis, the femoral component was closely matched in 80 knees (58.0%), overhung in 14 (10.1%) and undercovered the bone in 44 (31.9%). In those with a gender-specific prosthesis, it was closely matched in 15 knees (10.9%) and undercovered the bone in 123 (89.1%). <\/jats:p><jats:p> Since we found no significant differences between the two groups with regard to the clinical and radiological results, patient satisfaction or complication rate, the goal of the design of the gender-specific CR-flex prosthesis to improve the outcome was not achieved in our patients. <\/jats:p>","DOI":"10.1302\/0301-620x.92b5.24129","type":"journal-article","created":{"date-parts":[[2010,4,30]],"date-time":"2010-04-30T23:25:18Z","timestamp":1272669918000},"page":"639-645","source":"Crossref","is-referenced-by-count":49,"title":["Comparison of standard and gender-specific posterior-cruciate-retaining high-flexion total knee replacements"],"prefix":"10.1302","volume":"92-B","author":[{"given":"Y.-H.","family":"Kim","sequence":"first","affiliation":[{"name":"The Joint Replacement Centre of Korea, Ewha Womans University, School of Medicine, MokDong Hospital, 911-1 MokDong, YangChun-Gu, Seoul 158-710, Korea."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Y.","family":"Choi","sequence":"additional","affiliation":[{"name":"The Joint Replacement Centre of Korea, Ewha Womans University, School of Medicine, MokDong Hospital, 911-1 MokDong, YangChun-Gu, Seoul 158-710, Korea."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.-S.","family":"Kim","sequence":"additional","affiliation":[{"name":"The Joint Replacement Centre of Korea, Ewha Womans University, School of Medicine, MokDong Hospital, 911-1 MokDong, YangChun-Gu, Seoul 158-710, Korea."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"42","reference":[{"key":"R1","doi-asserted-by":"crossref","unstructured":"Hitt K, Shurman JR 2nd, Greene K, et al.
