This left a total of 34 patients (37 hips) who underwent HRA and 38 (39 hips) who underwent THR. The mean follow-up was 59.4 months (52 to 70) in the HRA group and 60.6 months (50 to 72) in the THR group. There was no failure of the prosthesis in either group. Flexion of the hip was significantly better after HRA, but there was no difference in the mean post-operative Harris hip scores between the groups. The mean size of the acetabular component in the HRA group was significantly larger than in the THR group (49.5 mm vs 46.1 mm, p = 0.001). There was no difference in the mean abduction angle of the acetabular component between the two groups. <\/jats:p><jats:p> Although the patients in this series had risk factors for failure after HRA, such as low body weight, small femoral heads and dysplasia, the clinical results of resurfacing in those with Crowe type I or II hip dysplasia were satisfactory. Patients in the HRA group had a better range of movement, although neck-cup impingement was observed. However, more acetabular bone was sacrificed in HRA patients, and it is unclear whether this will have an adverse effect in the long term. <\/jats:p>","DOI":"10.1302\/0301-620x.94b6.28522","type":"journal-article","created":{"date-parts":[[2012,5,24]],"date-time":"2012-05-24T15:25:59Z","timestamp":1337873159000},"page":"768-773","source":"Crossref","is-referenced-by-count":13,"title":["Resurfacing arthroplasty for hip dysplasia"],"prefix":"10.1302","volume":"94-B","author":[{"given":"Q.","family":"Wang","sequence":"first","affiliation":[{"name":"Shanghai Jiao Tong University, Department\rof Orthopedics, Shanghai Sixth People\u2019s Hospital, 600\rYi Shang Road, Shanghai 200233, China."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"X.
