BACKGROUND: Identifying preoperative risk factors that may portend poorer operative outcomes remains a topic of current interest. In hip and knee arthroplasty patients, the presence of patient-reported allergies (PRAs) has been associated with worse pain and function after joint replacement. However, these results have not been replicated across studies, including in shoulder arthroplasty cases. The impact of PRAs on foot and ankle outcomes has yet to be studied. The purpose of our study was to evaluate whether PRAs influence patient-reported outcome in foot and ankle surgery...

BACKGROUND: Single-stage bilateral knee arthroplasty, even when unicompartmental, remains controversial, chiefly due to the risk of peri-operative complications. The primary objective of this study was to compare the short-term complication rate and cost of single- vs. two-stage bilateral unicompartmental knee arthroplasty (UCA). The secondary objective was to compare total hospital stay lengths and motion-range recovery. HYPOTHESIS: Single-stage bilateral UCA is a cost-saving alternative that is not associated with higher complication rates compared to two-stage bilateral UCA...

PURPOSES: A fixed severe valgus knee is a surgical challenge. A safe post-operative Hip-Knee-Ankle angle (HKA) range of 180° ± 4 was recommended, but recent studies mentioned equal results from outliers of this range. Nevertheless, no distinction was made between varus and valgus knees, as well as over-corrected or under-corrected knees. Did post-operative nonaligned total knee replacements (TKR) from fixed severe valgus knees behave differently from the properly aligned population? Did over-corrected knees behave differently from under-corrected knees? METHODS: Through a multi-center retrospective cohort study, we provided 557 knees of at least 10° of minimal pre-operative valgus; in this population 75 presented a post-operative Hip-Knee-Ankle angle (HKA) outside of the 180° ± 4 range; 23 of them had at least 5° of varus; 52 of them had at least 5° of valgus...

INTRODUCTION: Extremely heterogeneous revision rates in total ankle arthroplasty (TAA) of the upper ankle joint are reported and result to heterogeneous collectives and to short follow-up times. The aim is to investigate revision rates and the underlying reasons, as well as treatment outcome and quality of life after TAA in post-traumatic cases with sufficient follow-up. METHODS: In 2008-2013, 74 patients with post-traumatic arthrosis were treated using TAA with a Tornier Salto prosthesis, and 60 (35 males and 25 females; mean age 56) were followed-up (mean: 59 months; range 24-91 months)...

BACKGROUND: In the last 2 decades, total ankle replacement has gained greater acceptance as a treatment option in patients with end-stage ankle osteoarthritis. However, there is a lack of literature on total ankle replacement using a lateral transfibular approach. Therefore, we sought to report early clinical and radiographic results for a patient cohort treated with total ankle replacement using a lateral transfibular approach, performed by a single surgeon. METHODS: From October 2012 to December 2014, 55 primary total ankle arthroplasties using the Zimmer Trabecular Metal Total Ankle implant were performed in 54 patients (29 male and 25 female; mean age, 67...

The bi-articular m. gastrocnemius and the mono-articular m. soleus have different and complementary functions during walking. Several groups are starting to use these biological functions as inspiration to design prostheses with bi-articular actuation components to replace the function of the m. gastrocnemius. Simulation studies indicate that a bi-articular configuration and spring that mimic the m. gastrocnemius could be beneficial for orthoses or exoskeletons. Our aim was to test the effect of a bi-articular and spring configuration that mimics the m...

BACKGROUND: People who are affected by end-stage ankle arthritis are as disabled as those suffering from arthritis in other main articulations of the lower extremity. Once these patients become unable to perform their job duties, they leave the workforce and require financial aid from government agencies, which represents a considerable economic burden. Regardless of whether arthrodesis or arthroplasty is performed, we hypothesized that patients younger than 55 years at the time of surgery should be able to return to work within 2 years and require less social assistance...

The most common reason for a revision total ankle replacement procedure is a painful, stiff ankle even after the initial surgery. Limited and conflicting data are available regarding the change in sagittal foot and ankle range of motion after revision total ankle replacement surgery. We sought to determine whether revision total ankle replacements would reduce compensatory midfoot range of motion. In determining this, a novel radiographic measurement system with stable osseous landmarks is used. A retrospective medical record review of patients who had undergone revision total ankle replacement from January 2009 to June 2016 was performed...

Understanding trends in reimbursement is critical to the financial sustainability of orthopedic practices. Little research has examined physician fee trends over time for orthopedic procedures. This study evaluated trends in Medicare reimbursements for orthopedic surgical procedures. The Medicare Physician Fee Schedule was examined for Current Procedural Terminology code values for the most common orthopedic and nonorthopedic procedures between 2000 and 2016. Prices were adjusted for inflation to 2016-dollar values...

BACKGROUND Clinical studies indicate that in total ankle arthroplasty, postoperative implant subsidence and medial tilt become two significant concerns of the ankle replacement system, and which are associated with the contact between the bones and the talar component. Up to now, little attention has focused on the contact between the bones and the talar component. MATERIAL AND METHODS In order to address implant subsidence and medial tilt, one three-dimensional finite element model of contact between the bone and the talar components was built with the material properties of the cancellous bone interpolated from the experimental data, which represents variation of material properties through the cancellous bones...

Total ankle replacement (TAR) is a valid option for the treatment of ankle osteoarthritis. The traditional surgical approach for TAR is the anterior approach. Recently, the lateral transfibular approach to the ankle has gained popularity since a new TAR implant was designed to be performed via this approach that results in an ideal visualization of the center of rotation of the ankle and curved resections that allow for sparing bone cuts. The aim of the present paper is to present our preoperative, operative, and postoperative protocols for the treatment of the osteoarthritis of the ankle with TAR via lateral approach...

BACKGROUND: Total ankle replacement (TAR) represents an alternative to fusion for the treatment of end-stage ankle osteoarthritis. The aim of the present study was to retrospectively assess the frequency of infections between TARs with anterior and lateral transfibular approach at 12-months follow-up. METHODS: 81 TARs through an anterior approach and 69 TARs through a lateral approach were performed between May 2011 and July 2015. We compared surgical time and tourniquet time, as well as superficial and deep infections frequency during the first 12 postoperative months...

BACKGROUND: To examine the safety and efficacy of Masquelet's technique as a surgical method for treating the first metatarsophalangeal joint in cases of gout accompanied by a massive bone defect. METHODS: From January 2010 to January 2016, eleven patients (7 males and 4 females; mean age 33.1 years; range, 23-43 years) received surgical treatment for a first metatarsophalangeal joint tophus which caused a serious bone defect. The first metatarsophalangeal bone defects ranged from 3-6cm, or nearly 50% of the length of normal bone...

BACKGROUND: Periprosthetic cystic osteolysis is a well-known complication of total ankle replacement. Several theories have been proposed for its aetiology, based on individual biomechanical, radiological, histopathology and outcome studies. METHODS: Studies that met predefined inclusion/exclusion criteria were analysed to identify literature describing the presence of peri-prosthetic ankle cystic osteolysis. Quantitative data from the selected articles were combined and statistically tested in order to analyse possible relations between ankle peri-prosthetic bone cysts and specific implant characteristics...
