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.

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.

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 Which device(uncemented or cemented total hip replacement[UTR or CTR]) is more conducive to the revision of metal-on-metal total hip replacement(MoM-TR) is inconclusive. The purpose of this study was to assess the long-term outcomes of individuals who had undertaken UTR versus CTR following initial MoM-TR. Methods Two hundred and thirty-four individuals(234 hips) had received UTR or CTR following initial MoM-TR during 2007-2018 were reviewed . Outcomes reported in this analysis involving Harris Hip Scores(HHS) as well as the major orthopaedic complications(MOC) were gathered 3 months, 6 months, 12 months, and then every one year after revision. Results From the 12th month after revision to final follow-up, CTR yielded superior HHS than UTR. The MOC rates were 47.4% and 16.1% in the UTR and CTR groups, respectively. Between-group noteworthy divergences were noted regarding the rates of re-revision, prosthesis loosening, and periprosthetic fracture(10.3% for UTR vs 2.5% for CTR, p =0.015; 16.3% for UTR vs 5.9% for CTR, p = 0.011; and 12.0% for UTR vs 4.2% for CTR, p =0.045, respectively). Conclusion The superiority of CTR over UTR in terms of improving HHS and decreasing the MOC rate.

Objective To compare the clinical outcomes of primary metal-on-metal total hip replacement (MoM-TR) converted to uncemented total hip replacement (UTR) or cemented total hip replacement (CTR) in patients with femoral neck fractures (AO/OTA: 31B/C). Methods Patient data of 234 UTR or CTR revisions after primary MoM-TR failure from March 2007 to January 2018 were retrospectively identified. Clinical outcomes, including the Harris hip score (HHS) and key orthopaedic complications, were collected at 3, 6, and 12 months following conversion and every 12 months thereafter. Results The mean follow-up was 84.12 (67–100) months for UTR and 84.23 (66–101) months for CTR. At the last follow-up, the HHS was better in the CTR- than UTR-treated patients. Noteworthy dissimilarities were correspondingly detected in the key orthopaedic complication rates (16.1% for CTR vs. 47.4% for UTR). Statistically significant differences in specific orthopaedic complications were also detected in the re-revision rate (10.3% for UTR vs. 2.5% for CTR), prosthesis loosening rate (16.3% for UTR vs. 5.9% for CTR), and periprosthetic fracture rate (12.0% for UTR vs. 4.2% for CTR). Conclusion In the setting of revision of failed primary MoM-TR, CTR may demonstrate advantages over UTR in improving functional outcomes and reducing key orthopaedic complications.

Abstract Objective The aim of this study was to assess the short-term clinical outcome in dogs following a hip hemi-arthroplasty for the treatment of primary pathological disorders of the hip and as a salvage procedure following failure of the cup component of a total hip replacement. Materials and Methods Medical records of dogs that had a unilateral hip hemi-arthroplasty performed between 2015 and 2020 were reviewed. Data collected included follow-up orthopaedic examinations performed at 0, 2, 8 and 52 weeks postoperatively, pelvic radiography at 0, 8 and 52 weeks postoperatively and an owner questionnaire (Helsinki chronic pain index [HCPI]). Results Eleven unilateral hip hemi-arthroplasty procedures were identified. The median age at time of surgery was 3.6 years (8 months–10 years) and the median follow-up time was 13 months (range: 2 months–3 years). The HCPI for all dogs at follow-up was median 8 ± 7.30 (range: 5–25). Total HCPI was < 12 for 7/10 dogs and ≥ 12 for 3 dogs. Pelvic radiographs at 1 year confirmed osteointergration of the femoral stem implant and no evidence of implant subsidence or progression of osteoarthritis. However, there was some evidence of mild lucency of the acetabular bed around the prosthetic femoral head and mild peri-acetabular sclerosis in four cases. Conclusion Hip hemi-arthroplasty provides a clinically acceptable treatment for disabling disease of the coxofemoral joint with 10/11 patients achieving acceptable short-term clinical function. Long-term assessment of the hip hemi-arthroplasty and comparison with total hip replacement is indicated.

Nationwide Register Study

Background: Few previous studies have analysed the possible teratogenic effect of maternal total hip replacement (THR) on congenital anomalies. The aim of this study was to estimate the risk of major congenital anomalies in the offspring of women with THR. Furthermore, we compared the risks based on type of implant (metal-on-metal [MoM]/non-MoM). Methods: The study population for this register-based cohort study was gathered from six Finnish national registers. All fertile-aged females who underwent THR from 1980 to 2007 and three reference females for each THR patient without THR were selected. THR operation day was the start of the follow-up for both groups. Information on pregnancies, induced abortions (IA) and congenital anomalies was gathered for the years 1987–2007 and the proportions of congenital anomalies were compared. Results: In the THR group, 2429 women had 256 pregnancies, 205 (80.1%) deliveries and 51 (19.9%) IAs. In the reference group, 7276 women had 1670 pregnancies, 1443 (86.4%) deliveries and 236 (13.6%) IAs. There was no difference in the incidence of major anomalies between the THR (3.5%, n = 9) and the reference group (3.6%, n = 60), p = 0.91. In the THR group, there was no difference in the risk of major anomalies between the patients with a MoM-THR (10.5%, 2/19) and those with a non-MoM (2.9%, 7/241) (OR 3.93, 95% confidence interval 0.76–20.2; p = 0.13). Conclusions: Reassuringly, maternal THR does not appear to increase the risk of major congenital anomalies or pregnancies ending due to suspected foetal anomalies. Studies with larger study populations are needed to further assess the risk of anomalies in the offspring of women having MoM-THR.
