Does hydroxyapatite coating have no advantage over porous coating in primary total hip arthroplasty? A meta-analysis
There are some arguments between the use of hydroxyapatite and porous coating. Some studies have shown that there is no difference between these two coatings in total hip arthroplasty (THA), while several other studies have shown that hydroxyapatite has advantages over the porous one. We have collected the studies in Pubmed, MEDLINE, EMBASE, and the Cochrane library from the earliest possible y...
متن کاملHydroxyapatite coating does not improve uncemented stem survival after total hip arthroplasty!
BACKGROUND AND PURPOSE It is still being debated whether HA coating of uncemented stems used in total hip arthroplasty (THA) improves implant survival. We therefore investigated different uncemented stem brands, with and without HA coating, regarding early and long-term survival. PATIENTS AND METHODS We identified 152,410 THA procedures using uncemented stems that were performed between 1995 ...
متن کاملHydroxyapatite coating on porous zirconia
Since hydroxyapatite has excellent biocompatibility and bone bonding ability, porous hydroxyapatite ceramics have been intensively studied. However, porous hydroxyapatite bodies are mechanically weak and brittle, which makes shaping and implantation difficult. One way to solve this problem is to introduce a strong porous network onto which hydroxyapatite coating is applied. In this study, porou...
متن کاملHydroxyapatite coated femoral stems in primary total hip arthroplasty: a meta-analysis.
We conducted meta-analysis of clinical studies of HA coated femoral stems in hip arthroplasty. After an exhaustive literature search, we abstracted relevant data on the outcomes of stem survival from aseptic loosening and Harris Hip scores. The risk ratios and mean differences with 95% confidence intervals (CI) are reported. 9 studies met our inclusion criteria for the analysis. The cumulative ...
متن کاملHydroxyapatite Coating ~ to Porous-Coated Fixation
Fifteen patients had bilateral hip replacement with a porous-coated hip replacement in one hip and in the contralateral hip the same design. which had adjunctive hydroxyapatite coating on the porous coating. These patients were followed for an average of 6.5 years (range, 5-7.9 years). There was no difference in the clinical Harris Hip Scores between the two hips in these patients. The radiogra...
