“…The second issue is that among the surveyed studies there were differences in many important variables, such as patient age, patient weight, acetabular cup design, number of surgeons, implantation technique, and method of anchorage of the acetabular cup to the contiguous bone ( Table 3). The third issue is that although, in each of the surveyed studies, anteroposterior and/or lateral radiographs of the pelvis were taken, an assortment of methods were used to determine 2D linear wear rates, such as the computer-assisted edge-detection method introduced by Martell et that comparable wear rates were found when determinations were made using either two manual methods (PowerPoint versus Livermore; Longevity; 28 mm Co-Cr femoral head) [23] or two computer-assisted methods (Martell versus Livermore with Roman software; Crossfire; 28 mm Co-Cr femoral head; mean follow-up of 5.7 yr) [40]. The second limitation is that although in the majority of the reports of the surveyed studies, it was explicitly stated that the 2D linear rate was corrected for deformation without attendant wear (principally, creep) suffered during the bedding-in period, in other reports, this was not the case [3] [14] [23] [40] [45].…”

Furthermore, in cases in which it was explicitly stated that correction for bedding-in was done, there was variation in the duration considered as the length of the bedding-in period, examples being 2 months [13], 6 months [20], 1 year [5], and 2 years [19] post-implantation.…”

Clinical two-dimensional linear wear rate data for acetabular cup liners fabricated using approved brands of highly cross-linked ultra-high-molecular-weight polyethylene, as reported in 39 articles in the literature, were analyzed using a statistical technique called response surface methodology. The output was a series comprising16 acceptable combinations of femoral head diameter (HD), femoral head material (HM), and HXLPE brand (PB), each of which would yield the optimum wear rate (herein taken to be a wear rate of practically zero). An example of such a combination is 28-mm-diameter Oxinium ® femoral head articulated against an acetabular cup liner fabricated from Reflection TM HXLPE. The findings in this work may guide an orthopaedic surgeon's selection of the combination of HD, HM, and PB to use in a primary total hip joint replacement.

“…Femoral head penetration was assessed at day 1 and last follow-up using the Kang modification of the Dorr and Wan method 14,15 and the PowerPoint method, 16 which correlates with the 3-dimensional laser scanning methods of retrieved implants. 17 Similar to the Livermore method, 18 the PowerPoint method uses circles of different sizes to determine the centre of the acetabular shell in relation to the centre of the femoral head, and measure the distance of translation and the direction of wear (Fig.…”

Purpose. To evaluate the medium-term outcomes of total hip replacement (THR) using a thin highly cross-linked polyethylene (HXLPE) liner in an Asian population. Methods. Medical records of 20 men and 44 women aged 26 to 80 (mean, 59) years who underwent 80 THRs using a thin HXLPE liner by a single surgeon were reviewed. Indications for THR included dysplasia (n=26), avascular necrosis (n=26), osteoarthritis (n=22), rheumatoid arthritis (n=4), and ankylosing spondylitis (n=2). The surgical technique, implant used, and rehabilitation protocol were standardised. Radiographs were evaluated for cup migration and peri-implant radiolucency. Femoral head penetration was assessed at day 1 and last follow-up using the Kang modification of the Dorr and Wan method and the PowerPoint method. Results. After a mean follow-up of 7.5 (range, 5.0-11.9) years, no patient had undergone acetabular revision. Two hips were revised for the femoral stem. FemoralTotal hip replacement using a highly crosslinked polyethylene liner in Asians with small acetabulum head penetration did not correlate with sex, age at surgery, hip pathology, acetabular inclination angle, cup size, or liner thickness. The maximum femoral head penetration was 0.09 mm/year, which was below the osteolysis threshold of 0.1 mm/year. The mean±standard deviation femoral head penetration was 0.29±0.12 mm (or 0.04±0.02 mm/year) by the PowerPoint method and 0.17±0.22 mm (or 0.02±0.03 mm/year) by the Kang modification of the Dorr and Wan method. Femoral head penetration correlated with the number of years of follow-up (p=0.012). Conclusion. The use of a thin HXLPE liner in primary THR for patients with small acetabulum achieved good outcomes after a mean of 7.5 years.

“…In 2007–2008, the author received a research grant from the Korea Food and Drug Administration (KFDA) and conducted research focused on the issues of polyethylene wear and wear-related osteolysis26272829). The author noted that the Harris-Galante cups revealed clear lysis in the hip, which was observed in anteroposterior and both oblique radiographs, at an average of 8 years after surgery; the annual wear rate of conventional non-cross-linked UHMWPE was found to be 0.175 mm/yr.…”

In the 1960s, Sir John Charnley introduced to clinical practice his concept of low-friction total hip arthroplasty (THA). Although early designs were plagued by poor performance and even failure, there have been steady advances in implant designs, biomaterials, surgical techniques and an understanding of the biomechanical restoration of the hip; these advances have contributed to improvements in implant survival and clinical outcomes of THA in the past three decades. With improved wear resistance and mechanical reliability, a potential to last for at least 25 to 30 years are now available for THA. In this review, we focus on the evolution of THA and review current controversies and future directions of this procedure based on a single surgeon's 29-year of experience at a single institution.
