Comparative study of cemented and cementless hip prostheses in the same patient

Abstract

In 20 patients with bilateral total hip replacements a cementless prosthetic implantation on one side and a cemented arthroplasty on the other side were performed. The mean follow-up period was 6 years for the cementless and 7.5 years for the cemented hip. The only significant difference found was concerning pain, which was more frequent on the cementless side. Otherwise we were unable to ascertain a significant difference concerning mobility, walking capacity, complications, and patient assessment. A longer observation time will be required. Where pain relief is concerned, the cemented version will continue to be the gold standard.

“…15 Therefore the difference between these 2 procedures might wane, or even reverse. In our review, equivalence was reported from most of the studies; however, superiority of cemented THR could also be found from studies in all 4 categories in terms of pain, 23,44 thigh pain, 4,29,[53][54][55] and overall assessment. 4,53,55 The mean follow-up period for these studies ranged from 4 to 7.8 years.…”

“…Two years later, the cemented side was still superior in terms of pain. 23,44 No difference in HO formation was found between the 2 groups. 14,23 For the short-term clinical outcome, all but one study from non-matched pair 56 showed that cemented THR was superior to uncemented THR.…”

“…23,44 No difference in HO formation was found between the 2 groups. 14,23 For the short-term clinical outcome, all but one study from non-matched pair 56 showed that cemented THR was superior to uncemented THR. For the midterm clinical outcome, most of the studies suggested equivalence between cemented and uncemented THR; however, superiority of cemented THR could be found in some aspects from studies in all 4 categories.…”

“…16,34,41 The same finding also came from 2 matched pair comparisons 40,53 and 2 comparative studies in the same patient. 14,23 However, different findings were reported in 2 non-randomised comparisons. 26,30,54 Lieberman et al 26 found that the incidence of HO was greater after cemented (22%) compared with uncemented (9%) arthroplasty in patients with osteoarthrosis.…”

“…In addition, a matched pair subgroup was included in the 2 studies. Therefore, there were 12 publications in category N, 4,6,15,19,22,26,29,30,31,51,54,56 10 in category R, 11,16,24,33,34,36,41,45,46,55 5 in category M, 4,10,29,40,53 and 4 in category S. 14,21,23,44 The mean postoperative follow-up period ranged from one year to 9.3 years. Among all these studies, one was designed to compare cemented, porous-coated, and hydroxyapatite-coated THR 16 ; one was to compare cemented, uncemented, and hybrid THR.…”
