Objective This study was performed to assess the outcomes of Asian patients who underwent conversion from metal-on-metal total hip arthroplasty (MoM-THA) to cemented THA (CTHA). Methods One hundred and fifty-seven consecutive patients (157 hips) who underwent CTHA following primary MoM-THA from January 2005 to February 2015 were retrospectively analysed. The primary endpoints were the clinical outcomes. Follow-ups occurred at 3 months, 6 months, 1 year, 2 years, and then every 2 years following revision of MoM-THA. Results The mean follow-up after conversion was 10 years (range, 5–14 years). Statistically significant improvements in the mean Harris hip score were observed between the preoperative and final follow-up evaluations (62.71 ± 13.85 vs. 84.03 ± 16.21, respectively). The major orthopaedic complication rate was 16.5% (26/157). Six (3.8%) patients underwent revision at a mean of 3.5 ± 1.3 years after conversion, predominantly because of prosthesis loosening or recurrent dislocation. Nine (5.7%) patients developed prosthesis loosening at a mean of 2.6 ± 1.1 years following conversion, two of whom requested revision surgery. Eleven (7.0%) patients developed prosthesis dislocation, four of whom requested revision surgery. Conclusion CTHA may yield favourable functional outcomes and a reduced rate of major orthopaedic complications.

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.

Introduction: This study aimed to compare the clinical and radiographic results of 28-mm ceramic-on-ceramic (CoC) total hip arthroplasty (THA) to those of 32-mm CoC during a 5- to 15-year follow-up period. Methods: 107 joints (95 women and 6 men) underwent 28-mm CoC, and 60 (49 women and 7 men) underwent 32-mm CoC. The average patient age at the time of surgery was 56.1 and 55.7 years in the 28-mm and 32-mm CoC groups, respectively. Clinical and radiologic measurements of all patients were analysed. Results: The mean preoperative Harris hip score (HHS) was similar in the 2 groups (28-mm, 58.9; and 32-mm, 58.5). However, at final follow-up, the mean HHS of the 32-mm CoC (91.8) was significantly better than that of the 28-mm CoC (88.2) ( p = 0.003), as were the ranges of motion (ROM) for flexion (98.3 ± 13.5° vs. 87.3 ± 19.3°, p < 0.001) and abduction (27.8 ± 14.9° vs. 22.1 ± 19.3°, p = 0.007). The mean wear rate was 0.0044 mm/year for the 28-mm CoC and 0.0044 mm/year for the 32-mm CoC. No ceramic fractures were found in the 2 groups. One joint in the 28-mm CoC (0.9%) required revision owing to progressive osteolysis. Kaplan-Meier survival at 10 years, with implant loosening or revision THA as the endpoint, was 98.3% for 28-mm CoC and 100% for 32-mm CoC ( p = 0.465). Conclusion: There was no significant difference in ceramic-related complications between the 2 groups. Our study demonstrated that the 32-mm and 28-mm CoC are safe and are associated with good clinical outcomes.

Large-diameter head (LDH) metal-on-metal (MoM) total hip arthroplasty (THA) has lost popularity because of metal allergy or ALTRs (adverse local tissue reactions) in the past decade. Whether the surgical approach may influence the survival of LDH-MoM-THA has not been reported. From 2006 to 2009, we performed 96 LDH-MoM-THAs on 80 patients using an in situ head-neck assembly technique through a modified Watson-Jones approach. With a mean follow-up of 8.4 years (range, 6.3–10.1 years), the implant survival rate was 100%. All patients were satisfied with the results and the Harris Hip Score improved from 52 points to 98 points. No ALTRs were found, but 17.7% of the 96 hips (17 adverse events) experienced adverse events related to the cup, including 5 cases of outlier cup malposition, 11 cases of inadequate cup seating, and 1 acetabular fracture. The tissue tension that was improved by a muscle-sparing approach might lessen the chance of microseparation or edge-loading that is taken as the major risk for early implant failure. Further investigation of whether these LDH-MoM-THAs would fail or not would require a longer follow-up or even retrieval analysis in the future.

Purpose. To review cases of implantation of constraining acetabular components for unstable or recurrent dislocating total hip arthroplasty at the Department of Orthopaedics, Concord Hospital, Sydney. Methods. A retrospective analysis was performed on prospectively collected data of 13 consecutively enrolled patients. Results. From 1989 to 2000, 13 constraining acetabular components were implanted into 13 patients as a revision procedure. The surgical approach for the implantation of the constrained liner was posterolateral in 11 cases; a modified Hardinge approach was applied in 2 cases. The mean clinical follow-up duration was 43 months (range, 14–121 months) and the mean age at the time of surgery was 73 years (range, 52–84 years). No patients were lost to follow-up. Indications for using the constrained acetabular component were recurrent dislocation in revision hip replacements (n=8), and intra-operative instability (n=5). There were no episodes of dislocation of the constrained arthroplasty. In 7 cases, the constrained component was implanted into a previously well-fixed shell. Conclusion. We recommend the judicious use of the constrained component in cases of hip instability during or after total hip arthroplasty when other methods are not successful.

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.

Background: Gunshot injury of the hip joint was reported to constitute 2–17% of all extremity firearm injuries. However, there are few studies in the literature related to gunshot injuries of the hip joint. The aim of the current study was to present the results of 10 cases treated with arthroplasty following a gunshot injury to the hip joint together with the recommended treatment algorithm. Methods: Patients with a previous medical history of hip joint region gunshot injury who underwent total hip arthroplasty were retrospectively evaluated. Those with incomplete medical records or who were lost to follow-up were excluded. Patients were classified according to the severity of the previous gunshot injury to the hip joint region. Harris hip score (HHS) and Short Form-12 quality of life score were the main outcome measurements. Postoperative complications encountered during follow-up were recorded. Results: The mean age of the patients at the time of surgery was 29.9 years. The mean preoperative HHS was 25.2 points and it was 65.8 at the final follow-up. Patients with bullet fragments in the hip joint, classified as group 1, had better HHS, whereas those with contaminated hip joint with intestinal flora, classified as group 3, had worst HHS. Conclusion: Hip arthroplasty after hip joint gunshot injury is a good treatment choice in young patients to reduce pain and regain functions. However, very high infection rates can be seen in patients with accompanying intestinal injury.

The aim of this study is to present our experience with two-stage reimplantation in the management of the infected hip arthroplasty. Between January 1993 and December 2001 the replacement of the total hip arthroplasty in two stages was performed in 18 patients. There were 7 male and 11 female patients and the average age was 62 years. The mean follow-up after revision was 3.5 years. The mean postoperative Harris Hip Score averaged 78 (50–96) points. None of 18 patients had a recurrence of the infection. Two-stage reconstruction of the infected hip is preferred to one-stage exchange arthroplasty at our department because of higher rate of eradication of the infection.

This study aimed to report the outcome of total hip arthroplasty (THA) with an extensive hydroxyapatite (HA) coating for the fixation of a tapered femoral stem (Corail) in patients aged 60 or younger than sixty years with stage IV, V và VI osteonecrosis of femoral head. Subject and method: Descriptive prospective research of ninety osteonecrotic hips in ninety patients were available for clinical and radiographic analyses at minimum follow-up of 5 years. Results and Conclusion: The mean Harris hip score improved from 43.74 ± 9,25points preoperatively to 96.67 ± 3.82points at final follow-up. Seventy-four (100%) hips demonstrated stable bone ingrowth. No hips showed acetabular or femoral osteolysis radiolucency and loosening, or required revision for aseptic loosening. We believe that cementless THA with a Corail stem is a promising procedure for patients with osteonecrosis of the femoral head.

Introduction: Complex and revision Total Hip Arthroplasty (THA) is a challenging prospect in patients with acetabular bone deficiencies. Augmentation using allograft and trabecular metal (TM) are among some of the options in these situations. This study report the outcomes of 14 cases of complex and revision THA using acetabular augments performed in our institution between 2015 and 2018 Materials and Methods: In this retrospective study, data included demographic features, indication for THA, type of augments and clinical outcomes using the Harris hip score were collected for the to determine early results following THA. Results: The mean cohort age was 51.3 years. Gender distribution was equal with 7 male and female patients each. 7 THAs were augmented with allograft and 7 cases with TM augments. The average duration of follow-up was 16.9 months. Most patients (11 of 14) required complex primary THA following prior traumatic hip dislocations and its subsequent complications. The mean post-operative Harris hip score for functionality was 80.84 in our cohort at final follow-up (from an average of 33.8 pre-operatively). At present, there have been no reports of wound complications, infections or dislocations in this early cohort. Discussions: Complex/revision THA using allografts for acetabular augmentation have been used for decades with good and replicable results as shown in our series. TM is relatively new but current literatures show encouraging results. Both options have resulted in good outcomes in our cohort and further long term studies would be necessary before TM augments were to replace the need for allograft. Conclusions: Both allografts and TM acetabular augments showed good early results post-operatively in our cohort. With the improved flexibility of component selection and the lower risk of allograft infection, TM augments is currently our choice of acetabular augmentation and the early results are promising.

Aims Second-generation metal-on-metal (MoM) articulations in total hip arthroplasty (THA) were introduced in order to reduce wear-related complications. The current study reports on the serum cobalt levels and the clinical outcome at a minimum of 20 years following THA with a MoM (Metasul) or a ceramic-on-polyethylene (CoP) bearing. Methods The present study provides an update of a previously published prospective randomized controlled study, evaluating the serum cobalt levels of a consecutive cohort of 100 patients following THA with a MoM or a CoP articulation. A total of 31 patients were available for clinical and radiological follow-up examination. After exclusion of 11 patients because of other cobalt-containing implants, 20 patients (MoM (n = 11); CoP (n = 9)) with a mean age of 69 years (42 to 97) were analyzed. Serum cobalt levels were compared to serum cobalt levels five years out of surgery. Results The median cobalt concentration in the MoM group was 1.04 μg/l (interquartile range (IQR) 0.64 to 1.70) at a mean of 21 years (20 to 24) postoperatively and these values were similar (p = 0.799) to cobalt levels at five years. In the CoP control group, the median cobalt levels were below the detection limit (< 0.3 μg/l; median 0.15 μg/l, IQR 0.15 to 0.75) at 20 years. The mean Harris Hip Score was 91.4 points (61 to 100) in the MoM group and 92.8 points (63 to 100) in the CoP group. Conclusion This study represents the longest follow-up series evaluating the serum cobalt levels after 28 mm head MoM bearing THA and shows that serum cobalt concentrations remain at low levels at a mean of 21 years (20 to 24) after implantation.
