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...

Complex regional pain syndrome (CRPS) is a painful and disabling disorder that usually affects the extremities. This complication may affect the knee joint after total knee arthroplasty (TKA). We report a unique case of CRPS of the foot and ankle, which was an unusual involvement site for CRPS after TKA.

PURPOSE: Total ankle arthroplasty (TAA) and ankle arthrodesis (AA) are the main surgical treatment options for end-stage ankle arthritis. Although the superiority of each modality remains debated, there remains a lack of high-quality evidence-based studies, such as randomized controlled clinical trials, and meta-analyses of comparative studies. We performed a meta-analysis of comparative studies to determine whether there is a significant difference between these two procedures in terms of (i) clinical scores and patient satisfaction, (ii) re-operations, and (iii) complications...

BACKGROUND: Functional recovery following total ankle arthroplasty (TAA) is assessed with patient-reported metrics, but physical performance tests may allow for a more accurate assessment of patient function. We quantified correlations between patient-reported measures and physical performance tests in patients after TAA to determine the usefulness of physical performance tests in post-TAA assessment. METHODS: In total, 140 patients with end-stage ankle osteoarthritis were assessed prior to TAA and again at 12 and 24 months postoperatively...

BACKGROUND: Modern knee designs do not fully restore the anatomy and kinematics of the natural knee. This study evaluates the kinematic and kinetic changes of well-functioning patients with total knee arthroplasty (TKA) in comparison to a healthy age-matched control group while descending stairs and level walking. The aim was to have a baseline for further investigations of TKA patients with problems. METHODS: Fifteen patients satisfied with TKA (8♀/7♂; 66.8 ± 7...

: First metatarsophalangeal joint arthritis can stem from a biomechanical imbalance as in hallux abducto valgus, metabolic arthritidies such as rheumatoid or gout, and even in posttraumatic cases. Advanced arthritis in the foot and ankle can often become debilitating. Surgical intervention is often necessary. Revision of failed first metatarsophalangeal joint arthroplasty is often in the setting of bony erosion and lysis, cystic changes, and loss of bone stock. In this article, we describe first metatarsophalangeal distraction arthrodesis technique using tricortical calcaneus autograft with the aim of simplifying donor site graft harvesting and decreasing donor site morbidity while attaining successful osseous union...

: Background Impingement may be an underreported problem following modern total ankle replacements (TARs). The etiology of impingement is unclear and likely multifactorial. Because of the lack of conservative treatment options for symptomatic impingement after TAR, surgery is often necessary. Methods We retrospectively identified a consecutive series of 1001 primary TARs performed between January 1998 and December 2014. We identified patients who required a secondary surgery to treat soft-tissue and bony impingement by either an open or arthroscopic procedure...

BACKGROUND: Ankle replacement surgery is an established and accepted way to treat end stage ankle arthritis. Though there are multiple publications looking at results with various ankle replacement systems, most of them are single implant longitudinal studies from a single institution. There are, however, no prospective randomized studies evaluating the outcomes of different total ankle arthroplasty (TAA) systems; in fact, there are no comparative studies at all. METHODS: The comparative results of 3 different total ankle systems (INBONE, STAR, and Salto Talaris) were evaluated...

OBJECTIVES: The purpose of this study was to compare the intra-operative benefits and the clinical outcomes from kinematic or mechanical alignment for total knee arthroplasty (TKA) in patients undergoing revision of failed unicompartmental kneel arthroplasty (UKA) to TKA. METHODS: Ten revisions were performed with a kinematic alignment technique and 11 with a mechanical alignment. Measurements of the hip-knee-ankle angle (HKA), the lateral distal femoral angle (LDFA), and the medial proximal tibial angle (MPTA) were performed using long-leg radiographs...

OBJECTIVES: Modern three-component total ankle arthroplasty (TAA) has favorable clinical results and survival rates. However, radiographic deterioration and worsening of clinical symptoms may occur in patients with rheumatoid arthritis (RA) or non-inflammatory arthritis (NA). The associations between outcomes and clinical and radiological factors are not clear. We compared midterm clinical and radiographic outcomes after TAA between patients with RA and those with NA. METHODS: Twenty-six TAAs were performed using a three-component prosthesis, the FINE Total Ankle System during the study period...

BACKGROUND: Total ankle arthroplasty is an accepted alternative to arthrodesis of the ankle. However, complication and failure rates remain high. Long-term results of the Scandinavian Total Ankle Replacement (STAR) are limited, with variable complication and failure rates observed. This prospective study presents the long-term survivorship and postoperative complications of the STAR prosthesis. METHODS: Between May 1999 and June 2008, 134 primary total ankle arthroplasties were performed using the STAR prosthesis in 124 patients...

BACKGROUND: Increased surgeon volume may be associated with improved outcomes following operative procedures. However, there is a lack of information on the effect of surgeon volume on inpatient adverse events and resource utilization following total ankle arthroplasty (TAA). METHODS: A retrospective cohort study of TAA patients was performed using the Nationwide Inpatient Sample (NIS) from 2003 to 2009. High-volume surgeons were considered as those with volume ≥90th percentile of surgeons performing TAA...

BACKGROUND: Patients' perception of outcomes is not always defined by the absence of limitations/symptoms (resolution), but can also be characterized by behavioral adaptation and cognitive coping arising in cases with residual deficits. Patient-reported outcome measures (PROs) are designed to measure levels of function or symptoms, largely missing whether patients are coping with ongoing limitations. This study aimed to broaden the conventional definition of a "satisfactory" outcome following ankle reconstruction by comparing patient-reported outcomes of patients with and without residual symptoms and limitations...

Few reports in the literature have described the conversion of a surgically fused ankle to a total ankle replacement. The takedown of an autofusion and conversion to a prosthesis has not been described. We report the case of a patient with severe rheumatoid arthritis with an ankle autofusion fixed in equinus and severe talonavicular arthritis that was converted to ankle replacement using the Salto XT revision system. We describe the reasons why the decision was made to perform total ankle arthroplasty while concomitantly fusing the talonavicular joint, and discuss the rationale of the various surgical treatment options considered...
