Wear of a sequentially annealed polyethylene acetabular liner
BACKGROUND AND PURPOSE We previously reported on a randomized controlled trial (RCT) that examined the effect of adding tobramycin to bone cement after femoral stem migration. The present study examined femoral head penetration into both conventional and highly crosslinked polyethylene acetabular liners in the same group of RCT patients, with a minimum of 5 years of postoperative follow-up. P...
متن کاملIn Vivo Wear and Migration of High Cross Linked Poly Cups: a Rsa Study
Aseptic loosening attributed to wear debris mediated osteolyses is the major concern in hip arthroplasty. Modern highly cross linked polyethylene reduces wear by > 90% in vitro, seemingly without major disadvantages. It has however not yet been subjected to extensive in clinical testing with high accuracy methods. Since the in vivo wear situation is complex and lab results earlier have made inc...
متن کاملWear of moderately cross-linked polyethylene fixed bearing knee replacements
Cross-linked polyethylene has been explored as an alternative to conventional polyethylene in total joint replacement in order to reduce wear volume and decrease failure through polyethylene wear debris induced osteolysis [1]. Due to the demands of a total knee replacement, moderately cross-linked polyethylene is recommended to retain mechanical properties [2]. This study aims to investigate th...
متن کاملTotal Hip Arthroplasty Using Metal Head on a Highly Cross-linked Polyethylene Liner
PURPOSE This retrospective study was performed to evaluate the clinical results and measure polyethylene liner wear in total hip arthroplasty (THA) with highly cross-linked polyethylene. MATERIALS AND METHODS Except for patients who had died or were unable to have follow-up at least 2 years, 60 of 78 hips that underwent THA were included this study. The mean age was 64.5 years (range, 25-81 y...
متن کاملHighly Cross-linked Polyethylene Liner Dissociation from a Cement-less Modular Acetabular Shell: Two Case Reports
Liner dissociation of polyethylene from a cementless acetabular socket following total hip arthroplasty (THA) is a rare complication. Cross-linked polyethylene liner dissociation from AMS-HA shell (KYOCERA Med, Osaka, Japan) occurred in 2 out of the 4153 (0.04%) cases approximately 10 years after undergoing surgery at our institute. First case was an 80-year-old female who underwent right THA a...
