Abstract Introduction The cementless acetabular implants are commonly used in primary and revision hip arthroplasty. Reconstruction of acetabulum in case of bone defects can be challenging. The aims of this single center study are to review the mid-term outcomes of porous tantalum cups (TM) and evaluate complications. Methods The midterm outcome of a trabecular metal tantalum modular uncemented cup was evaluated in 59 hips in 58 patients. In our group, we had 23 males and 35 females. The mean age was 70.11 years (range, 30 to 87 years). Four patients were lost to follow-up and 13 died during the period without having further surgeries attributed to the hip arthroplasty. The remaining 41 patients (42 revision hip arthroplasties) had complete data available. Results The mean follow-up was 87 months, ranging from 24 to 144 months. Standard pelvic anteroposterior (AP) radiographs were used to assess and preoperatively classify acetabular defects as per Paprosky classification. The serial radiographs showed excellent stability, bone opposition and graft incorporation. Four patients had further surgeries. Two of these were due to infection (one superficial and one deep infection). One of the patients had washout and then removal of metal work, the other patient only had a washout and symptoms settled. One patient had vascular compromise and went for surgery to stem the bleeding. One patient had re-revision due to stem loosening and hence required surgery but the revision cup remained stable. We noted a 96% survival at an average of 7.2 years follow-up. Conclusion The mid-term results with the trabecular metal cementless cup appeared to be promising in both primary and revision hip arthroplasty, even in the presence of considerable bone loss which requires bone grafting and augments. Level of evidence IV.

Background. Two-stage revision hip arthroplasty is the gold standard for treatment of patients with chronic periprosthetic joint infection (PJI), but few studies have reported outcomes beyond short-term follow-up.Methods. A total of 155 patients who underwent two-stage revision arthroplasty for chronic PJI in 157 hips were retrospectively enrolled in this study between January 2001 and December 2010. The mean patient age was 57.5 years, the mean prosthetic age was 3.6 years, and the interim interval was 17.8 weeks. These patients were followed up for an average of 9.7 years.Results. At the latest follow-up, 91.7% of the patients were free of infection. The mean Harris hip score improved significantly from 28.3 points before operation to 85.7 points at the latest follow-up. Radiographically, there was aseptic loosening of the stem or acetabular components in 4 patients. In the multivariate survival analysis using a Cox regression model, repeated debridement before final reconstruction, an inadequate interim period, bacteriuria or pyuria, and cirrhosis were found to be the independent risk factors for treatment failure.Conclusion. Our data show that two-stage revision hip arthroplasty provides reliable eradication of infection and durable reconstruction of the joint in patients with PJI caused by a variety of pathogens.

Purpose: Revision hip arthroplasty is a very challenging procedure. Use of a modular distal fixation stem is one of the available options for revision arthroplasty in patients with proximal femoral bone deficiency. The purpose of this study was to evaluate mid- to long-term outcomes of cementless modular distal fixation femoral stem implantation in revision hip surgery. Methods: Clinical and radiological findings, complications, and stem survival rate were analyzed for 46 patients (48 hips) who underwent revision hip arthroplasty using a cementless modular distal fixation femoral stem. The mean patient age was 58.8 years (range 31–82 years) and the mean follow-up period was 95 months (72–122 months). The preoperative diagnoses were aseptic loosening (36 hips), infection (4 hips), ceramic fracture (4 hips), and femoral periprosthetic fracture (4 hips). Results: The mean Harris hip score improved from 56.6 preoperatively to 88.2 postoperatively at the last follow-up. All hips showed stable osteointegration and firm fixation. Complications involved four hips (8.3%); there was one case each of periprosthetic fracture, delayed union of osteotomy site, femoral perforation, and infection. One stem re-revision was performed for deep infection of the femoral side. The Kaplan–Meier survival rate was 97.6% at the final follow-up. Conclusion: Revision hip arthroplasty using a cementless modular distal fixation femoral stem showed satisfactory initial firm fixation and mid- to long-term survival rate. Complications can be minimized by careful surgical planning and meticulous procedure.

Abstract Background The extraction of a femoral stem during the revision hip arthroplasty can be a daunting task and can lead to catastrophic complications for the patient. A sound technique employed intraoperatively helps in speedy recovery of the patient and reduces the risk of future surgical interventions. In this study, we present a medium-term outcome of our novel Lancaster Cortical Window technique which can be used for removal of cemented or uncemented femoral stems. Methodology The study was conducted at a specialist centre in the North-West of the UK from January 2014 to May 2019. This is a retrospective case series where patients were treated surgically using Lancaster Cortical Window technique for removal of femoral implant during a revision hip arthroplasty. Patient’s electronic notes and the radiographs were used to evaluate the functional and radiological outcome. Results In this study, 18 patients were managed surgically using Novel Lancaster Window technique. The mean age of the all the patients was 81.5 years and the male to female ratio was 10:8. Fifteen patients underwent revision surgery for aseptic loosening of the femoral and acetabular component. Rest of the three patients had revision surgery for a broken femoral stem, intraoperative femoral canal perforation while implanting a total hip replacement femoral stem and infection. Twelve femurs were replanted with uncemented long femoral stems and six with long cemented stems. The cortical window osteotomy united in all the patients in 4.2 months (mean). The mean follow up of these patients is 20.9 months, and none of them had any implant subsidence or loosening at the time of their last follow up. Conclusion We believe Lancaster cortical window technique can be safely used for removal of cemented stems during revision hip arthroplasty without the need for expensive equipment’s.

ABSTRACT BACKGROUND: Highly porous Trabecular Metal™ acetabular components are increasingly being used in revision hip arthroplasty as they facilitate ingrowth, provide a useful mechanism to deal with bone loss and may decrease the risk of infection. The purpose of this audit was to describe: 1) the total number of hip arthroplasty surgeries over Ave years, the ratio of revision to primary hip arthroplasty and indications for revision; 2) the short-term outcomes of revision hip arthroplasty with Trabecular Metal™ components and augments METHODS: A retrospective folder and radiograph review of all patients who had revision total hip arthroplasty (THA) at a tertiary level hospital from February 2012 to February 2017 was done RESULTS: There were 979 THAs performed over the period - 863 (87%) primary THAs, and 116 (12%) hip revision cases performed in 107 patients. Of the 116 (107 patients) hip revisions, there were seven (6%) re-revisions in Ave patients. The indications for revision were aseptic loosening 67 (59%), septic loosening 11 (10%), liner wear 18 (16%), periprosthetic fracture Ave (4%), other 15 (13%). Trabecular Metal™ was used for revision in 16 hips (14 patients), which is 14% of the total 116 revisions. There were ten females and four males with an average age of 61 years. The average duration of follow-up in this group was 18.5 months (1.5-39.2). In these 16 Trabecular Metal™ hips, there were three (19%) early failures of fixation due to technical errors CONCLUSION: In our institution, 12% of the arthroplasty is revision surgery. The indications for revision are similar to published literature. Trabecular Metal™ revisions had a 19% early failure rate due to technical error Level of evidence: Level 4 Keywords: Trabecular Metal™, augments, total hip arthroplasty, revision hip arthroplasty

Objective: This study aimed to report the short-term results of retrograde tibiotalocalcaneal (TTC) nailing in a selected series of patients with fragility ankle fractures. Methods: This study included 17 patients who underwent primary retrograde TTC nailing from January 2016 to April 2019. The Olerud-Molander ankle score (OMAS) was recorded preoperatively and at the final follow-up. Results: Mean patient age was 81.5 years (range, 67-91 years), and mean follow-up duration was 20.9 months (range, 8-50 months). No patient was lost to follow-up. Eleven patients had diabetes. Thirteen patients were able to walk with an assistive device, and 4 with help from another person. Two patients died at 8 and 9 months after treatment. Radiographic healing was observed in 100% of the fractures. No deep infection or scarring problems were recorded. Two patients were wheelchair bound after treatment, whereas 15 recovered their previous autonomy. The mean OMAS score changed from 64.1 (range, 55-75) preoperatively to 55.3 (range, 45-65) postoperatively. Conclusion: Our results suggest that primary retrograde TTC nailing is a valid option in selected patients with fragility ankle fractures, multiple comorbidities, poor soft tissue condition, and difficulty in walking before the fracture.

Introduction: Reconstruction of acetabulum in case of bone defects can be challenging. The aim of this retrospective study was to investigate the 10-year survival of trabecular tantalum metal (TM) acetabulum component in revision hip arthroplasty operations and to evaluate complications. Methods: A total of 100 consecutive acetabulum revision hip arthroplasties (100 patients) were operated on between May 2004 and October 2006 at Kuopio University Hospital. The mean follow-up time was 9.4 years and the median was 11.5 years (SD 4.118; range 0.1–13.4 years). Kaplan-Meier survival analysis was performed to study the survival of patients to re-revision surgery. Intra- and postoperative complications and reasons for re-revision were evaluated. Results: The Kaplan-Meier analysis showed a cumulative proportion of revision hip survivorship of 66% at 13.4 years (SE 0.403, 95% CI, 10.886–12.466) based on the need for further re-revision surgery for any major reason. The Kaplan-Meier survival analysis of time to re-revision surgery due acetabular component loosening showed a cumulative proportion of survivorship of 98.9% at 13.4 years (SE 0.136; 95% CI, 12.998–13.529). There were a total of 41/100 complications and the most common complication was dislocation (24/100). Re-revision for any major reason was performed on 18/100 of the revision arthroplasties. The mean time to re-revision was 4.9 years (SD 5.247; range 0.1–13.2 years). Discussion: The trabecular TM acetabular component gives excellent outcomes regarding stability and fixation to the acetabulum in acetabulum revision hip arthroplasty at a minimum of ten years of follow-up. However, acetabular component malposition and the small head size (28 mm) are risk factors for dislocation.

Extensively coated long femoral stem revision hip arthroplasty is based on the principle of distal fixation at diaphyseal region, which can overcome the problem of proximal femoral bone stock deficiencies causing inadequate support and unstable fixation when using conventional length femoral stem. We performed a retrospective cohort analysis of 43 cases of revision hip arthroplasties using extensively hydroxyapatite-coated long femoral stem performed in our department from Jan 1998 to Dec 2005. Patients’ background demographic data, operative details and clinical outcome were analyzed. The mean age at revision surgery was 63.7 (32–84). The mean follow-up period was of 13.8 years (11–17.5 years). In the latest follow up, all patients reported either no or mild hip or thigh pain. 29.2% of patients were able to walk unaided, 25.0% were able to walk with stick, and 33.3% were able to walk with quadripod. The average Harris hip score measured in the latest follow up was 78.8 (55–100). 4.7% were complicated with implant loosening requiring re-revision and 4.7% were complicated with implant infection requiring implant removal. The survival rate was 89.9% at 17.5 years. The femoral stem without femoral fixation augmentation had better survivorship as compared with those with augmentation (p = 0.038). Extensively hydroxyapatite-coated long femoral stem is a good option for revision hip arthroplasty with good clinical outcome and high survival rate.

AimsThe advent of trabecular metal (TM) augments has revolutionized the management of severe bone defects during acetabular reconstruction. The purpose of this study was to evaluate patients undergoing revision total hip arthroplasty (THA) with the use of TM augments for reconstruction of Paprosky IIIA and IIIB defects.Patients and MethodsA retrospective study was conducted at four centres between August 2008 and January 2015. Patients treated with TM augments and TM shell for a Paprosky grade IIIA or IIIB defect, in the absence of pelvic discontinuity, and who underwent revision hip arthroplasty with the use of TM augments were included in the study. A total of 41 patients with minimum follow-up of two years were included and evaluated using intention-to-treat analysis.ResultsThere were 36 (87.8%) patients with a Paprosky IIIA defect and five (12.2%) patients with a Paprosky IIIB defect. The mean age was 56.7 years (28 to 94). There were 21 (51.2%) women and 20 (48.8%) men. The mean follow-up was 39.4 months (12 to 96). One (2%) patient died after eight years. No failures were noted in the series. The mean survivorship was 100% at the time of latest follow-up.ConclusionThe results of this multicentre study showed encouraging short- and mid-term results for the use of TM augments in the management of Paprosky grade IIIA and IIIB defects.
