BACKGROUND: Ten percent of patients with a deep-vein thrombosis (DVT) will develop a fatal pulmonary embolism (PE), often initially asymptomatic. The risks and benefits of pharmacological thromboprophylaxis are well documented in respect of total joint arthroplasty and hip fractures, but little is understood about the incidence of venous thromboembolism (VTE) or the potential risks and benefits of chemoprophylaxis in foot and ankle surgery. OBJECTIVE: To determine whether prophylactic chemoprophylaxis had any impact on the prevention of VTE in a cohort of foot and ankle surgical patients requiring the combination of below-knee cast immobilisation and non-weightbearing for ≥4 weeks...

BACKGROUND: The optimal operative management of hallux rigidus is still a matter for debate among surgeons. Despite arthrodesis widely considered to be the gold standard treatment, many surgeons advocate arthroplasty as a suitable alternative. There are, however, few long-term or high-quality studies evaluating these modalities. We present the 15-year follow-up of a randomized controlled trial. METHODS: This data is the follow-up to the original study published in 2005...

The aim of this study was to investigate clinical and radiographic outcomes in patients 50 years and younger vs patients older than 50 years undergoing total ankle replacement. Seventy consecutive patients who underwent primary total ankle replacement were included in this retrospective study. Patients were assessed clinically and radiographically. There was a statistically significant difference between the 2 groups for the American Orthopaedic Foot & Ankle Society score at final follow-up. The younger group had significantly greater improvement compared with the older group...

Pedobarographic gait analysis is a useful tool for the determination of loading distributions and alterations on the lower extremity and their reflection on the foot sole after many orthopaedic surgical applications. To date, there have been no studies evaluating the relationship between component alignment and changes of pedobarographic gait analysis in total knee arthroplasty (TKA). We aimed to investigate the effects of TKA and prosthetic alignment on the distribution of pedobarographic parameters. Quantitative gait patterns of 47 patients were prospectively evaluated by using pedobarography 1 week before surgery and at the seventh month, on average, postoperatively...

BACKGROUND: Venous thromboembolism (VTE) is a relatively common and potentially life threatening complication after major hip surgery. There are two main types of prophylaxis: chemical and mechanical. Chemical prophylaxis is very effective but causes bleeding complications in surgical wounds and remote organs. On the other hand, mechanical methods are free of hemorrhagic complications but are less effective. We hypothesized that mechanical prophylaxis is effective enough for Asians in whom VTE occurs less frequently...

INTRODUCTION: End stage hallux rigidus can be treated surgically by arthrodesis, excisional arthroplasty and implant arthroplasty. Evaluation of these techniques has focused on clinical indicators such as radiographic, complications and subjective examination. Little attention has been given to health related quality of life and the use of patient reported outcome measures is still infrequent. METHOD: An evaluation was undertaken in a community based podiatric surgery service...

BACKGROUND: Ankle distraction arthroplasty is one option for the treatment of severe ankle arthritis in young patients. The outcomes and factors predicting success in distraction arthroplasty are poorly understood. METHODS: From January 2011 to May 2015, 16 patients who had undergone ankle distraction arthroplasty for ankle arthritis were operated, including six males and ten females. All patients were available for analysis. The main outcome measurements included joint space on weight bearing radiographs, AOFAS-AH scores (American Orthopaedic Foot & Ankle Society ankle-hindfoot score), VAS scores and SF-36 scores...

Slipped capital femoral epiphysis (SCFE) is an adolescent disease that leads to retroversion of the femoral neck and shaft, relative to the head. Observing that patients with SCFE must walk with an outward foot progression angle and externally rotate the leg in order to flex the hip, we have been performing a femoral shaft rotational osteotomy wherein we rotate the lower femur 45° inward, relative to the upper femur. By correcting retroversion, our goal is to improve functional hip and knee motion, thereby mitigating the effects of SCFE impingement...

BACKGROUND: Ankle arthrodesis has long been the traditional operative treatment for posttraumatic arthritis, rheumatoid arthritis, infection, neuromuscular conditions, and salvage of failed ankle arthroplasty. It remains the treatment of choice for patients in whom heavy and prolonged activity is anticipated. We present our short term followup study of functional outcome of patients who underwent transfibular ankle arthrodesis for arthritis of ankle due to various indications. MATERIALS AND METHODS: 29 transfibular ankle arthrodesis in 29 patients performed between April 2009 and April 2014 were included in this study...

BACKGROUND: The concept of free interposition arthroplasty proved successful for small joints of the hand, wrist, and foot, particularly after the use of implants coated with pyrocarbon, which enhanced their tribologic and elastic properties. The present study reports preliminary outcomes of a pyrocarbon-coated interposition shoulder arthroplasty (PISA) implant. METHODS: This was a prospective study of 67 consecutive patients who underwent shoulder PISA at 9 centers...

AIMS: A failed total ankle arthroplasty (TAA) is often associated with much bone loss. As an alternative to arthrodesis, the surgeon may consider a custom-made talar component to compensate for the bone loss. Our aim in this study was to assess the functional and radiological outcome after the use of such a component at mid- to long-term follow-up. PATIENTS AND METHODS: A total of 12 patients (five women and seven men, mean age 53 years; 36 to77) with a failed TAA and a large talar defect underwent a revision procedure using a custom-made talar component...

This is the case of an 84-year-old patient 18 years after total knee replacement. Regular follow-up examinations did not take place beyond 10 years of implantation, so that subsequent wear of the polyethylene insert was not detected. The patient presented because of knee pain, swelling of the calf, and a drop foot. Examination showed a large ganglion with pressure on the peroneal nerve, and a loose knee replacement with severe inlay wear and extensive osteolysis around the tibial and femoral implants. This rare case demonstrates the importance of regular clinical and radiological follow-up examinations after total joint replacements, particularly in the long term...

OBJECTIVE: Whilst a number of risk factors for poor patient reported outcome measures (PROMs) following knee arthroplasty (KA) have been identified, unexplained variability still remains. The role of pre-operative foot and ankle status on such outcomes has not been investigated. The aim of this study was therefore to determine the association of clinical foot and ankle assessments with patient reported outcomes 1 year following KA. DESIGN: One hundred and fifteen participants from the Clinical Outcomes in Arthroplasty Study (COASt), underwent detailed foot and ankle assessments at baseline, prior to KA (2012-2014) and were followed up for self-reported outcomes 1 year after surgery...

PURPOSE: We sought to determine and quantify which subspecialties of orthopedic surgeons are operating off hours in an urban, quaternary-care, level 1 trauma center. MATERIALS AND METHODS: We used our clinical registry to identify 43,211 orthopedic surgeries performed between January 2008 and December 2011. Our outcome measures were the number and proportion of off-hour surgeries performed as well as the number and proportion of off-hours per subspecialty. The denominators were the total number of surgeries and the total number of surgical hours worked per subspecialty...
