“…Because patients with bilateral disease cannot protect the other side, the probability of progression of degenerative arthritis may be greater, and thus the choice of therapy has been difficult in such patients [11]. Kawate et al [13] reported, at the 25-year followup of patients who had valgus osteotomy for arthritic hips, the mean score of patients with unilateral hip involvement was higher than that of patients with bilateral involvement. Hisatome et al [11] reported a 10-year survivorship rate of 86.9% in 61 bilaterally affected cases subjected to unilateral rotational acetabular osteotomy in which symptoms on the unoperated side were mild and in which the end point was radiographic evidence of osteoarthritis progression.…”

Pelvic osteotomy for middle-aged patients with hip dysplasia remains controversial. We asked whether pelvic osteotomy would yield lower Harris hip scores and survivorship in older patients than in younger patients. We compared patients younger than 50 years (n = 123) with patients 50 years or older (n = 41). At last followup, the mean Harris hip scores improved similarly in both groups: from 60 to 89 points in the older group and from 63 to 92

Purpose The purpose of this study was to examine retrospectively the effectiveness of Sugioka's transtrochanteric valgus osteotomy (TVO) combined with the shelf procedure for patients who had advanced osteoarthritis (OA) of the hip with severe acetabular dysplasia. Methods Sixty-two hips in 61 patients were reviewed retrospectively between April 1993 and March 2009. Of these hips, 25 hips with the pre-operative acetabular head index (AHI) ≥ 60 % (single group) underwent a TVO, whereas the other 37 with AHI < 60 % (combined group) underwent a TVO combined with the shelf procedure. Results Using conversion to total hip arthroplasty as the endpoint, the Kaplan-Meier survival rates at ten years were calculated to be 85.5 % for the single group and 100 % for the combined group; there was a significant difference between the two groups (p<0.05, log-rank test). Similarly, calculated using progressive OA as the endpoint, survival rates at ten years were 69.5 % and 89.3 % respectively; there was also a significant difference between the two groups (p < 0.05, log-rank test). In the single group, the latest radiographic evaluations of the patients with the pre-operative AHI ≥ 70 % were significantly better than those of the patients with the pre-operative AHI < 70 % (P<0.05). Conclusion More satisfactory ten year results of TVO were obtained in cases that had a pre-operative AHI of ≥70 %, or where the shelf procedure was added. It is desirable that acetabuloplasty be added for patients with pre-operative AHI < 70 %.

“…24 Mou et al compared two surgical methods and found that one was better than another in the coverage rate, indicating that the higher the coverage rate, the better. 25 Most previous studies agreed that a higher acetabular coverage rate would give lower revision, 26,27 although this topic is still to be further explored. There is little research reporting the relationship among the Trilogy, the coverage rates and revision rates.…”

Objective Collarless‐polished‐tapered (CPT) stems have been widely used in total hip replacement (THR). Given that various types of cups are combined with CPT in clinical practice, however, what cup type performs the best for use with CPT is still unclear. This study aimed to investigate the effects of three types of commonly used cups with CPT on revision and survival life using multi‐factor analysis. Methods This study is a cohort study using the data between October 1998 to September 2021. The data of THR patients with ZCA All‐poly Acetabular Cup, Continuum Acetabular System, and Trilogy Acetabular System with CPT were collected from several hospitals in the UK. The patients aged from 20 to 97 (n = 5981, 2345 male and 3636 female). Age, gender, body mass index, diagnosis, surgeon grade, cup material, cup size, surgical approach, survival life, complications, and Harris hip scores (HHS) were analyzed in relation to revision status. SPSS statistical software was used to analyze the relationship among various factors. The main statistical methods included chi‐square with cross tables, analysis of variance (ANOVA) and survival analysis. Results The results in relation to HHS shows that the continuum cup has the best outcome in the postoperative period of 1 and 5 years (1 year = 90.7, 5 years = 91.3; P < 0.001); the Trilogy cup was the second (1 year = 88.4, 5 years = 87.3; P < 0.001); and the ZCA cup was the third (1 year = 84.6, 5 years = 82.4; P < 0.001). However, the Trilogy cup performed the best regarding survival life on revision while the Continuum cup was the worst. Conclusion When the CPT stem is combined with different cups, the trilogy cup shows the best characteristics in terms of survival trends with revision ratios compared with the continuum and ZCA cups, and is therefore recommended by this study.
