INTRODUCTION: Permanent dislocation of the patella (PDP) is a rare condition. In cases of PDP with tibiofemoral arthritis, total knee arthroplasty may be performed through a medial parapatellar approach with patellar realignment. In this article we present two cases of PDP with tibiofemoral osteoarthritis successfully treated via lateral approach TKA without any additional realignment procedure. We performed two total knee arthroplasties for PDP with lateral tibiofemoral arthritis through a lateral approach without any realignment procedure...

BACKGROUND: Topical tranexamic acid (TA) has been reported to be effective in reducing postoperative bleeding and transfusions after TKA. The main objective of this study was to retrospectively assess the effectiveness and safety of topical TA administration in patients undergoing simultaneous bilateral TKA. METHODS: We conducted a retrospective chart review of consecutive cohorts of patients undergoing simultaneous bilateral TKA. We compared the patients who received TA with patients from a similar time frame who did not receive TA...

PURPOSE: To evaluate intraoperatively the effects of femoral offset and head size on stability of the hip joints in total hip arthroplasty (THA) via posterior approach. METHODS: Thirty cementless THAs were included in this study. After acetabular shell and femoral broach fixation, trial reduction was repeated using a femoral neck (5- to 8-mm higher or standard offset) and a head (26 mm or 32 mm). To evaluate joint stability, range of internal rotation (IR) in hip flexion prior to posterior subluxation and range of external rotation (ER) in hip extension were measured...

BACKGROUND: Angiosarcoma (AS) is a rare and malignant tumor which mainly arises in the skin and superficial soft tissue and less frequently in deep soft tissue and bones. Some cases of AS are described in association with vascular and orthopedic devices. Nonetheless, only a few cases of AS around THA are reported in the literature. MATERIALS AND METHODS: We describe five cases of AS arising around total hip arthroplasty who received surgery at our institution (Istituto Ortopedico Rizzoli, Bologna, Italy), and we report the cases described in literature...

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...

PURPOSE: Obstructive sleep apnea (OSA) has been linked to higher rates of perioperative complications. Practice guidelines recommend minimizing opioids in this cohort to reduce complications. However, a paucity of evidence exists relating different levels of opioid prescription to perioperative complications. Our aim was to investigate if different levels of opioid prescription are related to perioperative complication risk in patients with OSA. METHODS: A total of 107,610 OSA patients undergoing total knee or hip arthroplasty between 2006 and 2013 were identified in a nationwide database and divided into subgroups according to the amount of opioids prescribed...

BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA) is globally endemic and is a leading cause of surgical site infection (SSI). The purpose of this study was to evaluate the incidence of SSI in MRSA carriers undergoing elective hip or knee arthroplasty, who had confirmed eradication and to compare it with incidence of SSI in non-MRSA carriers. METHODS: This is a retrospective analysis of 6613 patients who underwent elective total hip arthroplasty (THA; n = 3347) and total knee arthroplasty (TKA; n = 3266) at our institution...

The purpose of this quality improvement project was to determine whether an outcomes manager-led interprofessional team could reduce length of stay and direct cost without increasing 30-day readmission rates in the total joint arthroplasty patient population. The goal was to promote interprofessional relationships combined with collaborative practice to promote coordinated care with improved outcomes. Results from this project showed that length of stay (total hip arthroplasty [THA] reduced by 0.4 days and total knee arthroplasty [TKA] reduced by 0...

Normal wound healing with avoidance of early wound complications is critical to the success of total knee arthroplasty. The severity of acute complications includes less morbid problems, such as quickly resolved drainage and small superficial eschars, to persistent drainage and full-thickness tissue necrosis, which may require advanced soft-tissue coverage. To achieve proper healing, surgeons must respond to persistent drainage by addressing modifiable patient risk factors, using meticulous surgical technique, and implementing an algorithmic approach to treatment...

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...

HYPOTHESIS AND BACKGROUND: Chronic opioid therapy is an increasingly used modality for the treatment of osteoarthritis-associated pain. We hypothesized that chronic opioid use would be associated with adverse outcomes in shoulder arthroplasty. METHODS: A retrospective analysis of patients undergoing elective anatomic total shoulder arthroplasty (TSA) and reverse total shoulder arthroplasty (rTSA) at a single institution from 2012-2015 was performed. Patients were stratified by preoperative opioid use (nonusers, short-acting opioid users, and long-acting opioid users), and their postoperative clinical outcomes were assessed...

BACKGROUND: Readmission rate has emerged as an important metric to measure quality, but varying definitions and timeframes are used. We aimed to evaluate the impact of different readmission definitions (postoperative vs postdischarge) and timeframes (30 vs 90-day) on capturing surgery-related readmissions after primary total joint arthroplasty. METHODS: Patients who underwent primary total hip or knee arthroplasty between January 1, 2013 and December 31, 2015 were included...

BACKGROUND: More than a million surgeries are performed annually in the United States for hip or knee arthroplasty or hip fracture stabilization. One-fifth of these patients have blood transfusions during their hospital stay. Increases in transfusion rates have caused concern about increased adverse events from unnecessary transfusions. METHODS: We systematically reviewed randomized trials examining the effect of restrictive vs liberal transfusion thresholds on patients having major orthopedic surgery...

BACKGROUND: The goal of patellofemoral arthroplasty (PFA) is to replace damaged cartilage and correct underlying deformities to reduce pain and prevent maltracking. We aimed to determine how PFA modifies patellar height, tilt, and tibial tuberosity-trochlear groove (TT-TG) distance. The hypothesis was that PFA would correct trochlear dysplasia or extensor mechanism malalignment. METHODS: The authors prospectively studied a series of 16 patients (13 women and 3 men) aged 64...

BACKGROUND: Total hip arthroplasty (THA) is one of the most common reoperations after hip arthroscopy. Although arthroscopy causes changes in the hip joint and the surrounding soft tissues that can make THA more challenging, previous reports on arthroscopy before THA have not demonstrated any significant effect on clinical outcomes. METHODS: Patients who underwent a THA following an ipsilateral hip arthroscopy were matched to a control group of THA patients with no history of ipsilateral hip surgery...
