Abstract:

THR has become one of the most widely performed operations in orthopaedic surgery.. In Germany, more than 180,000 THRs are currently done annually with increasing tendency. We use four different types of endoprostheses: (1) cemented, (2) cement-less, (3) hybrid (cement-free implanted socket and cemented stem), and (4) hemi-endoprosthesis (cemented stem without socket). A total number of 600 patients were included in a prospective follow-up study during 5 to 20 years, with a mean follow-up period of 10 years. The relevant question of whether to use a cemented, hybrid, or cement-free version of THR is, in our opinion, no longer a concern. All the methods have their advantages, disadvantages, indications, and contraindications. After the "Endler-era", significant differences are not noted between the groups of cemented, hybrid, and cement-less implants that impact on the clinical results and loosening rates.
