BACKGROUND: We performed a retrospective cohort study to compare preoperative health-related quality of life (HRQoL) between patients with bilateral and those with unilateral end-stage ankle arthritis. We also compared midterm outcomes in a subgroup of patients who had undergone staged bilateral total ankle replacement (TAR) with the outcomes in the group treated with unilateral TAR. METHODS: The HRQoL before surgical treatment was compared between 53 patients with bilateral end-stage ankle arthritis identified from the Canadian Orthopaedic Foot and Ankle Society Prospective Ankle Reconstruction Database and 106 patients with unilateral arthritis selected from the same database...

BACKGROUND: Total ankle arthroplasty (TAA) is a rapidly growing treatment for end-stage ankle arthritis that is generally performed as an inpatient procedure. The feasibility of outpatient total ankle arthroplasty (OTAA) has not been reported in the literature. We sought to establish proof of concept for OTAA by comparing outpatient vs inpatient perioperative complications, postoperative emergency department (ED) visits, readmissions, patient satisfaction, and cost analysis. METHODS: From July 2010 to September 2015, a total of 36 patients underwent TAA...

BACKGROUND: The key to a successful knee replacement is restoring normal kinematics with a neutral alignment, thus a hip-knee-ankle (HKA) angle of 180° (within 3° limits). Conventional TKR is proven to have excellent results but relies in extensive visual referencing of bony landmarks. Customised cutting blocks provide accurate bone cuts, also lowering the risk of fat embolism, blood loss and operating time. METHOD: We share our experience comparing two different TKA techniques using patient specific instrumentation (PSI) with the Visionaire knee and conventional instrumentation (CVI) from the same system (Genesis II Smith&Nephew)...

Total ankle replacement (TAR) is an accepted treatment for end-stage ankle arthritis. When concurrent subtalar joint pathologic features exist, ipsilateral subtalar joint arthrodesis (STJA) can be performed either simultaneous with TAR or as a staged procedure. Limited data exist on the effect of talar component subsidence and prosthesis survivorship. The present study purpose was to evaluate the effect of STJA on talar component subsidence after primary TAR and its effect on TAR survivorship. All patients, a minimum of 18 years old, from a single institution with modern-generation TAR and 1-year minimum follow-up data available were evaluated...

The authors describe a novel suture fixation technique that combines a doubled suture with a sliding knot. The knot can be tied in both open and arthroscopic surgery to fix torn tendons/ligaments and fractured/osteotomized bones. The advantages of the doubled-suture Nice knot include strength, adjustability, simplicity, and versatility. This technique, which has proven useful in the authors' practice for the past 10 years, has replaced metallic wires and cables for bone fixation. The doubled-suture Nice knot can also be tied over a double-button and has been used for ankle syndesmosis, acromioclavicular joint separation repair, and coracoid bone block fixation...

During a routine dissection of an adult embalmed male cadaver for educational purpose in the department of anatomy at AIIMS, New Delhi, India, a rare unilateral variation of extensor digitorum longus (EDL) was found which is a muscle of anterior compartment of the leg. There was a split tendon of EDL muscle in the anterior compartment of left leg which became a common tendon in front of the ankle joint. This common tendon of EDL muscle again divided into four slips and were inserted in to the lateral four toes...

BACKGROUND: Several studies have examined the effect of insurance on the management of various orthopedic conditions. The purpose of our study was to assess the effect of insurance and other demographic factors on the operative management of tibiotalar osteoarthritis. METHODS: The National Inpatient Sample (NIS) database was used to identify patients who underwent a total ankle arthroplasty (TAA) or tibiotalar arthrodesis (TTA) for tibiotalar osteoarthritis. Insurance status was identified for each patient, and the proportions of each insurance type were computed for each operative modality...

BACKGROUND: Traditional intraoperative referencing for total ankle replacements (TARs) involves multiple steps and fluoroscopic guidance to determine mechanical alignment. Recent adoption of patient-specific instrumentation (PSI) allows for referencing to be determined preoperatively, resulting in less steps and potentially decreased operative time. We hypothesized that usage of PSI would result in decreased operating room time that would offset the additional cost of PSI compared with standard referencing (SR)...

INTRODUCTION AND OBJECTIVES: The purpose of this study was to determine whether some foot/ankle surgeries would benefit from routine use of low molecular weight heparin (LMWH) as postoperative DVT prophylaxis. METHODS: We conducted a formal cost-effectiveness analysis using a decision analytic tree to represent the risk of complications under a scenario of no prophylaxis and a scenario of routine LMWH prophylaxis for 4 weeks. The two scenarios were compared for five procedures: 1) Achilles tendon repair (ATR), 2) total ankle replacement (TAR), 3) hallux valgus surgery (HVS), 4) hindfoot arthrodesis (HA), and 5) ankle fracture surgery (AFS)...

#18
Elisa S Arch, Bretta L Fylstra
The large, late-stance energy generated by the ankle is believed to be critical during gait. However, the distal foot absorbs/dissipates a considerable amount of energy during the same phase. Thus, the energy generated by the combined ankle-foot system is more modest, which raises questions regarding the necessity of such a large ankle power and the interplay between foot and ankle energetics. This study aimed to evaluate our conservation of energy hypothesis, which predicted if distal foot energy absorption/dissipation was reduced, then less energy would be generated at the ankle and thus the same combined ankle-foot energetics would be achieved...

BACKGROUND AND AIMS: Circulating Angiotensin Converting Enzyme 2 (ACE2) activity in chronic kidney disease (CKD) patients without previous history of cardiovascular disease (CVD) has been associated with classical risk factors (older age, diabetes and male gender). Furthermore, silent atherosclerosis has been described as a pathological link between CKD and CVD. We analyzed baseline ACE2 activity in non-dialysis CKD stages 3-5 (CKD3-5) patients as a biomarker of renal progression, silent atherosclerosis and CV events after 2 years of follow-up...

BACKGROUND: This study provides an updated comparison of the reoperation rates following primary ankle arthrodesis and total ankle replacement on the basis of observational, population-based data from California. We previously reported data from 1995 to 2004, and our current study includes new data from 2005 to 2010. Our hypothesis was that total ankle replacement would demonstrate increasing utilization and lower complication rates given advances in implant design and growth in surgeon experience...
