BACKGROUND: The most common reason for revision total hip arthroplasty remains polyethylene wear. Development dysplasia of the hip and revision situations requires a conscious compromise of implant position. The surgeon should know about the consequence on wear via a possible change in hip contact force. The objective of this study is to investigate whether annual wear is dependent on hip contact force. METHODS: Forty-five inserts (DuraLoc, DePuy) that were explanted in our department were included...

BACKGROUND: In revision total hip arthroplasty (THA), proximal femoral bone loss creates a challenge of achieving adequate stem fixation. The purpose of this study was to examine the outcomes of a monoblock, splined, tapered femoral stem in revision THA. METHODS: Outcomes of revision THA using a nonmodular, splined, tapered femoral stem from a single surgeon were reviewed. With a minimum of 2-year follow-up, there were 68 cases (67 patients). Paprosky classification was 3A or greater in 85% of the cases...

OBJECTIVE: It is unclear whether hydroxyapatite (HA) coating of uncemented cups used in primary total hip arthroplasty (THA) improves bone ingrowth and reduces the risk of aseptic loosening. We therefore investigated survival of different uncemented cups that were available with or without HA coating. METHOD: We investigated three different cup types used with or without HA coating registered in the Nordic Arthroplasty Register Association (NARA) database that were inserted due to osteoarthritis (n=28,605)...

BACKGROUND: Poliomyelitis is a viral, nervous system disease that affects both the upper and the lower extremities. The treatment of severe coxarthrosis in these patients with total hip arthroplasty (THA) has been widely questioned because of the high risk of subsequent complications. The aim of the present study was to describe both radiological and medium term clinical results in a series of patients with post polio residual paralysis that underwent THA. MATERIALS AND METHODS: We report a retrospective review of a series of 5 five patients diagnosed with severe coxarthrosis secondary to post polio residual paralysis who were operated between 2008 and 2012...

BACKGROUND: Failed total hip arthroplasty caused by mechanically assisted crevice corrosion (MACC) has serious consequences such as adverse local tissue reaction. Revision is currently indicated for significant hip pain, stiffness, and dysfunction; hip instability; progressive bone loss; and soft tissue destruction. Outcomes of this revision surgery are not yet completely understood. METHODS: We examined the surgical outcomes at a minimum of 6 months (average, 25; range, 7-68 months) in a cohort of 27 consecutive patients who underwent revision total hip arthroplasty for MACC associated with a single implant vendor and taper type...

BACKGROUND: Obesity, smoking, uncontrolled diabetes, and poor dental health are modifiable risk factors for revision total joint arthroplasty. To protect patients from revision surgery while also reducing cost, some joint arthroplasty practices use these conditions as contraindications until they are improved. However, this practice is variable among joint arthroplasty surgeons. We hypothesize that a relatively high rate of revision arthroplasty patients had modifiable risk factors at the time of primary surgery...

INTRODUCTION: 3rd generation ceramic bearings were introduced in total hip arthroplasty (THA) with the potential to have better mechanical strength and wear properties than their predecessors. At present, there are few studies looking at the long-term results of this latest generation of ceramic bearings.The purpose of our study was to investigate the long-term clinical and radiographic results of 3rd generation ceramic-on-ceramic THA and the incidence of ceramic specific complications such as squeaking and bearing surface fracture...

As the rate of hip and knee arthroplasty procedures increases, so will the rate of interprosthetic fractures. Several factors, including bone quality, bone quantity, and stability of the prosthetic components, play a role in determining the appropriate operative treatment. Patients with stable components should undergo reduction and internal fixation, while patients with loose components should undergo either revision arthroplasty, with or without additional fixation, or conversion to total femur replacement...

Background and purpose - The original Müller acetabular reinforcement ring (ARR) was developed to be used for acetabular revisions with small cavitary and/or segmental defects or poor acetabular bone quality. Long-term data for this device are scarce. We therefore investigated long-term survival and radiographic outcome for revision total hip arthroplasty using the ARR. Patients and methods - Between October 1984 and December 2005, 259 primary acetabular revisions using an ARR were performed in 245 patients (259 hips)...

INTRODUCTION: The outcomes of total hip arthroplasty (THA) for the treatment of posttraumatic arthritis after acetabular fractures were inferior to those after primary non-traumatic THA. METHODS: This study was performed in academic level I trauma center. From January 2011 to December 2014, a consecutive series of 21 patients (9 females), with average age of 56.7 years (range 29-75 years) who had posttraumatic hip joint arthritis after acetabular fractures, were included in our study...

BACKGROUND: In arthroplasty data, patients with staged bilateral total joint arthroplasty (TJA) pose a problem in statistical analysis. Subgroup analysis, in which patients with unilateral and bilateral TJA are studied separately, is sometimes considered an appropriate solution to the problem; we aim to show that this is not true because of immortal time bias. METHODS: We reviewed patients who underwent staged (at any time) bilateral TJA. The logical fallacy leading to immortal time bias is explained through a simple artificial data example...

The use of total hip arthroplasties (THA) has been continuously rising to meet the demands of the increasingly ageing population. To date, this procedure has been highly successful in relieving pain and restoring the functionality of patients' joints, and has significantly improved their quality of life. However, these implants are expected to eventually fail after 15-25 years in situ due to slow progressive inflammatory responses at the bone-implant interface. Such inflammatory responses are primarily mediated by immune cells such as macrophages, triggered by implant wear particles...

BACKGROUND: Medical complications and preexisting conditions frequently place the surgeon in the unenviable position of choosing between the serious and potentially life-threatening effects of thrombosis, or the issue of bleeding and surgical site complications. The aim of this research was to determine if health utility could be a consideration before choosing to therapeutically anticoagulate in the hip and knee arthroplasty patient. METHODS: The quantitative risks and effectiveness of treatment options for venous thromboembolism, atrial fibrillation, acute coronary syndromes, ischaemic stroke and mechanical heart valves were evaluated from previously published data...

BACKGROUND: Due to demographic change, more proximal femoral fractures can be expected in the future. However, accurate growth rates as well as follow-up research extending more than 1 year postsurgery are still lacking. MATERIALS AND METHODS: First, we defined inclusion and exclusion criteria for the retrospective cohort study. Based on these, we collected all surgical interventions conducted between 1 January 2006 and 31 December 2015. For a total of 2000 consecutive procedures, we retrieved and analysed a total of 12 variables influencing mortality...

BACKGROUND AND AIMS: An adverse reaction to metal debris is a known complication after large diameter head metal-on-metal total hip arthroplasty. However, the failure rate varies depending on the implant design. Therefore, we investigated the prevalence of adverse reaction to metal debris, as well as the symptoms and risk factors after undergoing a ReCap-M2a-Magnum large diameter head metal-on-metal total hip arthroplasty. MATERIALS AND METHODS: Between 2005 and 2012, 1188 patients (1329 hips) underwent ReCap-M2a-Magnum total hip arthroplasty at our institution...
