BACKGROUND: The outcome of revision surgery in arthroplasty is based on a precise diagnosis. In addition, the treatment varies based on whether the prosthetic failure is caused by aseptic or septic loosening. Algorithms can help to identify periprosthetic joint infections (PJI) and standardize diagnostic steps, however, algorithms tend to oversimplify the treatment of complex cases. We conducted a process analysis during the implementation of a PJI algorithm to determine problems and deviations associated with the implementation of this algorithm...

Pseudoaneurysms are uncommon in patients with trauma, but can cause diagnostic difficulty and result in significant morbidity. Etiologies range from penetrating and nonpenetrating trauma to operative injury during fracture fixation, arthroscopy, total joint arthroplasty, and hardware loosening and removal. Pseudoaneurysms can conspicuously present as a pulsatile mass with an audible bruit, or as a subtly expanding hematoma. In either case, the complications can be serious if diagnosed late. The authors report a case of a pseudoaneurysm arising from the descending geniculate artery following a tibial plateau fracture...

BACKGROUND: The utilization of hip arthroscopy continues to increase in the United States. The purpose of this study was to examine trends in hip arthroscopy procedures and outcomes. METHODS: We performed a retrospective cohort study using Optum Labs Data Warehouse administrative claims data. The cohort comprised 10,042 privately insured enrollees aged 18-64 years who underwent a hip arthroscopy procedure between 2005 and 2013. Utilization trends were examined using age-specific, sex-specific, and calendar-year-specific hip arthroscopy rates...

BACKGROUND: Total hip arthroplasty (THA) is commonly elected following failed arthroscopic treatment of femoro-acetabular impingement (FAI). The purpose of this study was to evaluate post-operative outcomes of primary THA in patients who had previously undergone arthroscopic treatment for FAI. METHODS: A retrospective, matched case-control study was conducted. The case group included 39 patients who underwent THA after previous hip arthroscopy for FAI. Thirty-nine patients who had a primary THA without previous hip arthroscopy served as a control group and were matched for age, sex and body mass index...

BACKGROUND: The indications for hip preservation surgery have expanded to include treatment of hip pathology in older adults. While several studies have examined the efficacy of hip arthroscopy in the setting of osteoarthritis, there has been no review of outcomes in older adults. PURPOSE: To review the outcomes of hip arthroscopy in older adults and identify factors associated with treatment failures. STUDY DESIGN: Systematic review. METHODS: PubMed, EMBASE, and the Cochrane Library were searched through March 2016 for studies reporting outcomes of primary hip arthroscopy in patients older than 40 years...

INTRODUCTION: The diagnostic algorithm in cases of assumed low-grade infection after total knee arthroplasty is discussed controversial. The aim of this study was to evaluate the reliability of neosynovium biopsies via knee arthroscopies in predicting a periprosthetic knee joint infection (PJI). METHODS: From 2010 to 2015, 56 consecutive patients received a diagnostic arthroscopy of the knee joint by reason of an assumed PJI. In 34 cases, a revision arthroplasty was performed after the diagnostic arthroscopy...

INTRODUCTION: Stiffness and loss of motion following total knee arthroplasty (TKA) is a complex and multifactorial complication that may require manipulation under anesthesia (MUA). However, patient and surgical factors that potentially influence the development of knee stiffness following TKA are not fully understood. The purpose of this study was to identify patient and surgical factors that may influence range of motion loss following TKA by assessing a cohort of patients that underwent MUA and comparing them to a matched cohort of patients without complications...

Surgery of the temporomandibular joint (TMJ) is increasingly recognised as a subspecialist area of interest within our specialty and many procedures such as arthroscopy, arthroplasty, and replacement of the TMJ are becoming increasingly centralised and restricted to certain regions. We previously made a national survey of trainees and have sought to augment this with a survey of trainers to find out the nature of practice and patterns of referral nationally. We have also examined the consultants' expectations of competent final-year trainees...

PURPOSE: Due to the juvenility of research in the field of periprosthetic joint infection (PJI), approaches employed for diagnosis of PJI vary amongst surgeons in different geographic regions. The aim of this study was to determine common diagnostic approaches utilized by European knee arthroplasty surgeons for the diagnosis of PJI. METHODS: A task force was established for questionnaire development, consisting of surgeons and clinical researchers who each had a record of publishing in the field of PJI...

PURPOSE: To (1) report clinical outcomes, complication rates, and total hip arthroplasty (THA) conversion rates for patients age 40 or older who underwent hip arthroscopy, and (2) report any age-related predictors of outcome identified in the literature. METHODS: MEDLINE, EMBASE, and PubMed were searched for relevant studies and pertinent data were abstracted from eligible studies. No meta-analysis was performed because of heterogeneity amongst studies. RESULTS: Seventeen studies were included in this review comprising 16,327 patients, including 9,954 patients age 40 or older...

Successful hip arthroscopy depends on proper patient selection and reasonable patient expectations. The purpose of this study is to report the results of hip arthroscopy in orthopaedic surgeons who represent the most informed cohort. This report is based on a retrospective review of prospectively collected data among 24 orthopaedic surgeons (1 bilateral). Follow-up averaged 48 months (range 12-120 months). They were all males with an average age of 45 years (range 30-64 years). All improved with an average of 18 points (preoperative 75; post-operative 93); although one underwent repeat arthroscopy and one was converted to total hip arthroplasty at 54 months...

INTRODUCTION: There are currently no guidelines supporting the use of routine chemoprophylaxis to prevent deep vein thrombosis (DVT) in arthroscopic surgery. Studies and meta-analysis show opposing views on its routine use in arthroscopy. This study aimed to examine the incidence of DVT in a prospective cohort of knee arthroscopy and knee arthroplasty patients, and to analyse the risk factors contributing to DVT. METHODS: All patients scheduled to undergo knee arthroscopy or arthroplasty over a two-year period were included...

Osteoarthritis is a ubiquitous condition, affecting 26 million Americans each year, with up to 17% of adults over age 75 suffering from one variation of arthritis. The hip is one of the most commonly affected joints and while there are conservative options for treatment, as symptoms progress, many patients eventually turn to surgery to manage their pain and dysfunction. Early surgical options such as osteotomy or arthroscopy are reserved for younger, more active patients with less severe disease and symptoms...

BACKGROUND: Patients often ask their doctors when they can safely return to driving after orthopaedic injuries and procedures, but the data regarding this topic are diverse and sometimes conflicting. Some studies provide observer-reported outcome measures, such as brake response time or simulators, to estimate when patients can safely resume driving after surgery, and patient survey data describing when patients report a return to driving, but they do not all agree. We performed a systematic review and quality appraisal for available data regarding when patients are safe to resume driving after common orthopaedic surgeries and injuries affecting the ability to drive...

Venous thromboembolism is uncommon after knee arthroscopy, and there are no guidelines for thromboprophylaxis in elective routine knee arthroscopy. Preoperative evaluation of common thrombophilias should provide guidance for postarthroscopy thromboprophylaxis in otherwise healthy patients who are at high risk for venous thromboembolism. This study assessed 10 patients with venous thromboembolism after total hip or knee arthroplasty. Patients were assessed if venous thromboembolism occurred within 6 months after knee arthroscopy (n=10) or total hip or knee arthroplasty (n=21)...

Several orthopedic registries have described the incidence of total knee arthroplasty (TKA) in patients who have undergone knee arthroscopy. Patient risk factors may play a role in the conversion rate from knee arthroscopy to TKA. This study quantifies the incidence of conversion of knee arthroscopy to TKA from a US mixed-payer database and describes some common patient risk factors for conversion. The medical records of more than 50 million patients who were treated between 1998 and 2014 were mined with a commercially available software platform...

BACKGROUND: Symptomatic global retroversion of the acetabulum, as diagnosed on plain radiographs of the pelvis, has traditionally been treated with reverse periacetabular osteotomy, which improves posterior undercoverage and eliminates the anterior pincer lesion. There is a paucity of literature on hip arthroscopy in this group, secondary to theoretical concern of iatrogenic dysplasia, subsequent instability, and arthritis. PURPOSE: To evaluate the outcomes of hip arthroscopy for patients with a radiographic diagnosis of acetabular retroversion, using patient-reported outcomes, visual analog scale (VAS), patient satisfaction, and pre- and postoperative Tönnis grades...
