“…Concerning the choice of femoral head, few data are available, with only small series and at short follow-up intervals 41 , 42 and no long-term follow-up RCTs directly comparing metal versus ceramic heads coupled with XLPE. 16 In a recent study by Cafri et al, 37 based on a systematic analysis of registry data, an overall equal long-term performance was found between metal and ceramic heads.…”

Total hip arthroplasty (THA) is widely considered one of the most successful surgical procedures in orthopaedics. It is associated with high satisfaction rates and significant improvements in quality of life following surgery. On the other hand, the main cause of late revision is osteolysis and wear, often a result of failure of bearing surfaces.Currently, several options are available to the surgeon when choosing the bearing surface in THA (ceramic-on-ceramic (CoC), ceramic-on-polyethylene (CoPE), metal-on-polyethylene (MoPE)), each with advantages and drawbacks.Very few studies have directly compared the various combinations of bearings at long-term follow-up. Randomized controlled trials show similar short- to mid-term survivorship among the best performing bearing surfaces (CoC, CoXLPE and MoXLPE). Selection of the bearing surface is often ‘experience-based’ rather than ‘evidence-based’.The aim of this paper is therefore to evaluate the main advantages and drawbacks of various types of tribology in THA, while providing practical suggestions for the surgeon on the most suitable bearing surface option for each patient.Cite this article: EFORT Open Rev 2018;3 DOI: 10.1302/2058-5241.3.180300.

“…In their retrospective review, Li et al 1 have described the medium-term clinical and radiological results of Zweymüller-Plus total hip arthroplasty (THA) in 185 Chinese patients (207 hips). The articulation size was 28 mm, with conventional ultra-highmolecular-weight polyethylene (UHMWPE) over the acetabular side and third-generation alumina ceramics on the femoral side.…”

Purpose: Here, we report the complications of endoprosthesis with threaded cups according to our application in cases of complicated acetabulum (hip revisions and femoroacetabular impingement (FAI)). Methods: A total of 504 patients was analyzed, including 189 men and 315 women. For re-implanted patients (n = 49), the mean time to re-implantation was 6.3 years and the average age at re-implantation was 54.7 years. For censored patients (n = 455), the mean time to censoring was 5.5 years and the average age of the implant was 55.7 years. Among the patients that were censored, 77 died and 378 patients did not experience an event necessitating re-implantation. Results: For the total study population, the Kaplan-Meier estimate of 5 year survival is 0.94 and of 10 year survival is 0.85. 90% of the implants survived 7 years, 80% of the implants survived almost 12 years and 70% of implants survived almost 15 years. Kaplan-Meier survival analysis suggests that men have higher survival than women. Age of the patient at the time of implant was not a statistically signifi cant factor for re-implantation (p value = 0.21) but sex was (p value = 0.02). Women had 2.25 times more risk of being re-implanted than men. Conclusions: In our case series, the failure rate, as a result of aseptic loosening, was 7.4% (n = 51). More than half the failure cases (56%) required re-implantation. Over one-third (37%) of the primary arthrosis cases, were found to be FAI, lessening the frequency of diagnosis of the former. In our clinic, the threaded cup seems to be indispensable in hip revision surgery and in treating FAI.
