Wear Analysis of Highly Cross-Linked Polyethylene in Young and Active Patients at Average Fourteen Years: A Concise Follow-Up of a Previous Report

Highly Crosslinked Polyethylene Can Reduce Wear Rate in THA for High-Demand Patients: A Matched-Paired Controlled Study

“…Furthermore, sport practice after THA is a source of satisfaction for patients. The literature shows significant increased clinical scores after THA in young and athletic patients, with HHS exceeding 90 points [15,33,38,39]. The present study results corroborate those findings, the mean postoperative clinical scores of the patients being greater than 90/100 for all studied parameters.…”

“…In their 15-year follow-up retrospective study, Rames et al found a HXLPE linear wear rate of 0.0297 mm/y among impact sports participants, with no significant difference when less active patients were involved [38]. Gaudiani et al found similar results, with a linear wear of 0.032 mm/y and a survivorship rate of 100% with a 14 year follow-up among a young and athletic patient cohort [39]. With a HXLPE linear wear of 0.03059 mm/year ±0.0084 mm/y without periprosthetic osteolysis, the results of this present study comparing two groups of patients implanted by the same surgeon with the same approach and using the same implants, only differing by the type of polyethylene are consistent with the literature.…”

The influence of contact stress on the wear of cross-linked polyethylene

“…Since wear of the UHMWPE cup/liner is the main reason for the failure and revision of MoP hips 6 , the need for more wear resistant materials has arisen. Cross-linked polyethylene (XLPE) is one of the alternatives that has been used in hip arthroplasty for the past 10 to 20 years and clinical studies show that cross-linking has improved the wear resistance of the material and XLPE has a superior wear resistance compared to UHMWPE 3,8,[16][17][18][19][20][21] .…”

Recent update on crosslinked polyethylene in total hip arthroplasty

“…Gaudiani et al [11] evaluated 57 consecutive hips with a mean follow-up of 14 years using annealed XLPE and found it to have excellent long-term behavior: a 0.032 mm/year wear rate, no observed osteolysis, no implant failure because of loosening on either the acetabular or femoral side. Conversely, Tsukamoto et al [12] warned of possible excessive wear for an annealed XLPE between 10 and 15 years.…”
