Long-term outcomes of uncemented or cemented arthroplasty revision following metal-on-metal total hip arthroplasty failure: A retrospective observational study with a mean follow-up of 7 years

Abstract Background: A high rate of metal-on-metal total hip arthroplasty (MoM-THA) has been well-known. The aim of this study was to compare the long-term outcomes of patients who had undergone uncemented or cemented THA(UTHA or CTHA) following initial MoM-THA failure.Methods: Data from 234 patients (234 hips) who were treated with UTHA or CTHA following initial MoM-THA failure during 2007 - 2018 were retrospectively compared. Follow-up occurred 3 months, 6 months, 1 year, 2 years, and then every 1 year after conversion. The mean follow-up was 84.15 months (67 - 101 months). The primary endpoint was the Harris Hip Scores (HHS); secondary endpoint was the incidence of major orthopaedic complications.Results: The HHS demonstrated statistically greater differences in Group CTHA than in Group UTHA 12 months after conversion. From the 12th month after conversion to the final follow-up, CTHA yielded superior functional outcomes than UTHA. Between-group noteworthy differences were observed regarding the rates of re-revision, aseptic loosening, and periprosthetic fracture (10.3% for UTHA vs 2.5% for CTHA, p = 0.015; 16.3% for UTHA vs 5.9% for CTHA, p = 0.011; and 12.0% for UTHA vs 4.2% for CTHA, p = 0.045, respectively). Conclusion: In the setting of revision following initial MoM-THA failure, we found definite evidence of the superiority of CTHA over UTHA in regard to improving functional outcomes and decreasing the incidence of major orthopaedic complications.

Abstract Background A high rate of complications due to metal-on-metal (MoM) revisions has been relatively commonly documented. The purpose of this retrospective study was to compare the long-term outcomes of patients who had undergone uncemented or cemented total hip arthroplasty (THA) revision for prior primary MoM THA failure.Methods Data from 234 patients (234 hips) who underwent uncemented or cemented THA (UTHA or CTHA) for prior primary MoM THA failure during 2007 - 2018 were retrospectively analysed. Follow-up occurred 3 months, 6 months, 1 year, 2 years, and then every 1 year after conversion. The mean follow-up time was 84.15 months (range, 67 - 101 months). The primary endpoint was the modified Harris Hip Score (HHS). The secondary endpoint was the major orthopaedic complication rate.Results The HHS demonstrated statistically greater differences in the CTHA group than in the UTHA group 12 months after conversion. From the 12th month after conversion to the final follow-up, CTHA yielded better functional outcomes than UTHA. There were significant differences in the rates of re-revision, aseptic loosening, and periprosthetic fracture between the groups (10.3% for UTHA vs 2.5% for CTHA, p = 0.015; 16.3% for UTHA vs 5.9% for CTHA, p = 0.011; and 12.0% for UTHA vs 4.2% for CTHA, p = 0.045, respectively).Conclusion In the setting of revision for primary MoM THA failure, we found definite evidence of the superiority of CTHA over UTHA in terms of improving functional outcomes and decreasing the major orthopaedic complication rate.

Objective To retrospectively compare the mid-term outcomes of uncemented or cemented total hip arthroplasty (THA) revision for prior primary metal-on-metal (MoM) THA failure. Methods Data from 278 patients (278 hips) who underwent uncemented THA (UTHA) or cemented THA (CTHA) for prior primary MoM-THA failure from 2006 to 2016 were retrospectively analysed. Follow-up was performed 6 months, 1 year, 2 years, and then every 2 years after conversion. The mean follow-up time was 96 months (range, 64–128 months). The primary endpoint was the modified Harris hip score (HHS). The secondary endpoint was the major orthopaedic complication rate. Results The HHS showed significantly greater differences in the CTHA than UTHA group 12 months after conversion. From the 12th month after conversion to the final follow-up, CTHA yielded better functional outcomes than UTHA. There were significant differences between the UTHA and CTHA groups in the rates of re-revision (14.4% vs. 4.9%, respectively), aseptic loosening (17.3% vs. 6.8%, respectively), and periprosthetic fracture (11.5% vs. 3.9%, respectively). Conclusion CTHA has more advantages than UTHA in terms of improving functional outcomes and decreasing the major orthopaedic complication rate.

Background: Adverse reactions to metal debris are significant complications after metal-on-metal total hip arthroplasty. Recently, late appearances of adverse reactions to metal debris and subsequent need for reoperations have been reported with small-diameter head metal-on-metal devices. We retrospectively investigated mid-term clinical outcomes of small-head metal-on-metal total hip arthroplasty. Methods: We reviewed 159 hips in 139 patients who had a small-head metal-on-metal total hip arthroplasty (M2a Taper; Biomet, Warsaw, IN) with a minimum 5-year follow-up and documented postoperative complications. Results: Focal osteolysis in either the femur or acetabulum was observed in 12 hips (7.5%, 44 months after surgery on average), with pseudotumor observed in 8 hips (5%, 120 months after surgery on average). Four hips (2.5%) had dislocations (84 months after surgery on average) and six hips (3.8%, 122 months after surgery on average) underwent reoperation. Conclusion: Small-head metal-on-metal total hip arthroplasty is associated with a high degree of complications at mid-term follow-up period. Considering this, we discourage the use of metal-on-metal total hip arthroplasty regardless of head size.

Abstract Purrpose Metal-on-metal (MoM) total hip arthroplasty (THA) has been a subject of recent discussion and concern due to the early failures caused by local and systemic adverse reactions related to specific designs. The aim of this study is to analyze the outcomes and survival rates of a single brand of MoM implants implanted in a consecutive series of patients at a single institution. Methods Between 2007 and 2012, 116 (118 hips) patients were evaluated at a mean follow-up of 6.6 years after primary THA. The diagnosis leading to surgery was osteoarthritis (80 patients) and proximal femoral fracture (36 patients). A single design of THA was implanted. All patients were evaluated before surgery and postoperatively at 1, 3, 6, and 12 months by clinical scores and radiographic studies. The data analysis was made using Student's t-test. Results The minimum follow-up was of 4 years, with a mean follow-up of 6.6 years. Two aseptic loosenings of the acetabular component were recorded (one per group), which were not associated with local or systemic complications related to metal ion release. Both were revised by an isolated acetabular cup substitution with metal-on-polyethylene couplings. Nonprogressive radiolucency lines < 2 mm in zone 2 were observed in other six patients around the acetabular component without clinical manifestation (four in the arthritis group and two in the fracture group). Postoperative Harris Hip Score and SF-36 (36-Item Short Form Survey) score improved in both groups. Conclusion Despite several MoM implants showing early complications and failures, a specific MoM design may be associated with good clinical results at a mid- to long-term follow-up. Level of Evidence This is a therapeutic case series, Level 4 study.

Abstract Background Given the unexpected high rate of failure following metal-on-metal total hip replacement (MoM-THR), it is expected that more MoM-THR patients will experience revision. The long-term outcomes regarding the primary MoM-THR revised to cemented THR (CTHR) remain controversial. The purpose of this retrospective review was to evaluate the long-term outcomes of patients who underwent conversion from MoM-THR to CTHR. Methods A total of 220 patients (220 hips) who underwent a conversion of primary MoM-THR to CTHR from March 2006 to October 2016 were retrospectively reviewed. The primary outcomes were the functional outcomes assessed using the Harris hip scores (HHS) and major radiographic outcomes. Follow-ups occurred at 3 months, 6 months, 1 year, 2 years, and then every two years after revision. Results Mean follow-up was 10.1 years (5–13 years). Distinct improvements were detected in the mean HHS between the preoperative and last follow-up analysis (62.35[±8.49] vs. 84.70[±14.68], respectively, p < 0.001). The key orthopaedic complication rate was 18.2% (27/148). Seven (4.7%) cases experienced a CTHR failure at a mean of 3.4 (±1.2) years after revision MoM-THR, mostly attributed to recurrent dislocation. Conclusion CTHR might yield an acceptable functional score and a low rate of the key orthopaedic complications.
