“…On the other hand, the main limitation of our study is that it is based on an implant especially prone to rapid wear and the initiation of OL. The overall 12-year survival for ABG I prostheses, found in our previous study, was 55% [10], which is in agreement with several studies [39][40][41][42] but contrasts with others [11,43,44]. The reasons for the disparity are still not clear, but this issue is discussed elsewhere [10].…”

We analysed data from 155 revisions of identical cementless hip prostheses to determine the influence of patient-, implant-and surgery-related factors on the polyethylene wear rate and size of periprosthetic osteolysis (OL). This was calculated by logistic regression analysis. Factors associated with an increased/decreased wear rate included position of the cup relative to Kohler's line, increase in abduction angle of the cup, traumatic and inflammatory arthritis as a primary diagnosis, and patient height. Severe acetabular bone defects were predicted by an increased wear rate (odds ratio, OR=5.782 for wear rate above 200 mm 3 /y), and increased height of the patient (OR= 0.905 per each centimetre). Predictors of severe bone defects in the femur were the increased wear rate (OR=3.479 for wear rate above 200 mm 3 /y) and placement of the cup outside of the true acetabulum (OR=3.292). Variables related to surgical technique were the most predictive of polyethylene wear rate.

“…Indeed, Oosterbos et al found signifi cantly better survival for ABG I prosthesis in patients with a mean age of 72 years when the youngest was 55 years old 15 . In contrast, others 17,21 used the same prosthesis in a wider spectrum of patients including those younger than 60 years and found much better survival than in the current study suggesting the reasons for observed diff erences might be more complex. Primary diagnosis is another factor that could infl uence the prosthetic survival (Tables 5a, b).…”

“…This signifi cantly compromised the survival of the prosthesis in spite of the fact that the vast majority of these cases were those of the Hartofi lakidis type I which should result in survivorship comparable to primary osteoarthritis 22 . Moreover, Castoldi et al used ABG I in 49 postdysplastic hips (31.2 %) and they did not report inferior results for that group of patients 17 . In addition, smaller cups were implanted more often in dysplastic cases (Table 1) resulting in the risk for revision being more than 4 times higher in cases with cups of 46 or 48 mm in size than in those with a larger cup.…”

“…On the one hand, this conclusion is close to studies reporting outcomes after a minimum of ten-year follow-up with the same implant 13,14 . On the other hand, other centres have provided signifi cantly better data [15][16][17] . Furthermore, when only aseptic loosening was included, the survivorship for ABG I prosthesis in this study was comparable with the best results published for ABG I especially at the site of the stem.…”

Background: Hydroxyapatite coated (HAC) hip implants have been used in clinical practice for more than two decades. However, the majority of studies have reported only intermediate term outcomes that are not reliable for predicting long-term behavior in all implants. The aim of this study was to determine the performance of HAC total hip arthroplasty in younger patients over a 10-year follow-up period. Methods and Results:This was an observational retrospective study of a 137 consecutive hips with the ABG I prosthesis. Of these, 128 were available for the last investigation. Median duration of follow-up was 10.9 years. The mean age at time of index surgery was 46±6.7 years. Probability of implant survival was estimated using the Kaplan-Meier method. The overall 12-year cumulative survival was 0.55 (95% CI, 0.443-0.659). Periprosthetic osteolysis (57 %) was the most frequent reason for failure followed by aseptic loosening (28 %). When only aseptic loosening was included in the analysis, the same fi gures for cup and stem were 0.873 (95% CI, 0.808-0.938) and 0.992 (95% CI, 0.976-1.0), respectively. Patients with a smaller cup size were those at high risk for revision due to wear-related complications (odds ratio, OR=4.3; 95% CI, 1.734-10.555).Conclusion: This study reports one of the poorest 12-year survivorship data for cementless acetabular component in the literature. The main reason for premature failure was osteolysis, strongly related to high wear rate of polyethylene.

“…The osteolytic effect of wear debris depends not only on particle size and shape but also mainly on the particle volume released into the surrounding tissue [14,24]. Numerous authors have reported, with standard 28-mm heads, linear wear rates greater than 0.2 mm per year always produce wear particle-induced osteolysis, whereas this mostly is absent at annual wear rates less than 0.05 to 0.1 mm per year [1,4,10,11,20,29,32,34,35]. Therefore, increasing wear resistance of the PE for acetabular cups has been a major target.…”

Wear particle-induced osteolysis is a major cause of aseptic loosening in THA. Increasing wear resistance of polyethylene (PE) occurs by increasing the crosslink density and early reports document low wear rates with such implants. To confirm longer-term reductions in wear we compared cross-linked polyethylene (irradiation in nitrogen, annealing) with historical polyethylene (irradiation in air) in a prospective, randomized clinical study involving 48 patients who underwent THAs with a minimum followup of 7 years (mean, 8 years; range, 7-9 years). The insert material was the only variable. The Harris hip score, radiographic signs of osteolysis, and polyethylene wear were recorded annually. Twenty-three historical and 17 moderately cross-linked polyethylene inserts were analyzed (five patients died, three were lost to followup). At 8 years, the wear rate was lower for crosslinked polyethylene (0.088 ± 0.03 mm/year) than for the historical polyethylene (0.142 ± 0.07 mm/year). This reduction (38%) did not diminish with time (33% at 5 years). Acetabular cyst formation was less frequent (39% versus 12%), affected fewer DeLee and Charnley zones (17% versus 4%), and was less severe for the cross-linked polyethylene. The only revision was for an aseptically loose cup in the historical polyethylene group. Moderately cross-linked polyethylene maintained its wear advantage with time and produced less osteolysis, showing no signs of aging at mid-term followup.
