INTRODUCTION: Severe post-traumatic ankle arthritis poses a reconstructive challenge in young and active patients. Although technically demanding and despite unsolved immunological issues, bipolar fresh total osteochondral allograft (BFTOA) represent an intriguing option to arthrodesis and prosthetic replacement. The purpose of this paper is to evaluate the outcomes of a series of 48 ankle BFTOA at 10 years follow up and to investigate the rate of survival long term. METHODS: 58 patients underwent BFTOA, of these 48 were available for follow up...

BACKGROUND: Osteotomy is a rational approach to slowing knee osteoarthritis progression by modifying loads, thereby avoiding joint replacement in younger individuals. Varus femoral osteotomy is recommended only in patients with more than 10° of valgus. The objective here was to assess outcomes of tibialvarus osteotomy in patients with lateral compartment tibio-femoral osteoarthritis and less than 10° of valgus. MATERIAL AND METHODS: A single-centre retrospective study was conducted in 19 consecutive patients managed by high tibialvarus osteotomy between January 2005 and May 2012...

BACKGROUND: With observed success and increased popularity of growth modulation techniques, there has been a trend toward use in progressively younger patients. Younger age at growth modulation increases the likelihood of complete deformity correction and need for implant removal before skeletal maturity introducing the risk of rebound deformity. The purpose of this study was to quantify magnitude and identify risk factors for rebound deformity after growth modulation. METHODS: We performed a retrospective review of all patients undergoing growth modulation with a tension band plate for coronal plane deformity about the knee with subsequent implant removal...

BACKGROUND: The surgical treatment of end-stage tibiotalar arthritis continues to be a controversial topic. Advances in surgical technique and implant design have lead to improved outcomes after both ankle arthrodesis (AA) and total ankle arthroplasty (TAA), yet a clear consensus regarding the most ideal form of treatment is lacking. In this study, the outcomes and complications following AA and TAA are compared in order to improve our understanding and decision-making for care and treatment of symptomatic tibiotalar arthritis...

Background: Whether antenatal and neonatal vitamin D status have clinical relevance in fracture prevention has not been examined extensively, although observational studies indicate that fetal life may be a sensitive period in relation to bone growth and mineralization during childhood.Objective: We examined whether 25-hydroxyvitamin D3 [25(OH)D3] concentrations in stored neonatal dried blood spot (DBS) samples are associated with pediatric fracture risk. We hypothesized that in particular, low neonatal vitamin D status may be a risk factor for fracture incidence among children...

Jyoshid R Balan
BACKGROUND: The defects over the leg, foot and ankle are best covered with a thin pliable flap. The use of muscle flap for the reconstruction of these defects leaves a grafted, aesthetically inferior result. The medial sural artery perforator (MSAP) free flap gives a thin pliable tissue for the reconstruction with better aesthesis. METHODS: The study design was retrospective case analysis over a period of 2 years. All the patients who underwent flap for leg, foot and ankle defect reconstruction in the form of MSAP free flap were included in the study...

James A Nunley, Kamran S Hamid
BACKGROUND: Osteonecrosis of the talar body represents a complex clinical challenge with treatment options currently limited to core decompression, vascularized and nonvascularized bone-grafting, total talar replacement, and hindfoot arthrodesis. Vascularized pedicle bone-grafting from the cuboid to the talus is a potential alternative to contemporary operative options for replacement of necrotic talar tissue with viable bone. We aimed to analyze functional and radiographic outcomes of vascularized pedicle bone-grafting from the cuboid for the treatment of talar osteonecrosis in a consecutive series of patients spanning a 12-year period...

REVIEW
Federico Giuseppe Usuelli, Camilla Maccario
The role of the surgeon learning curve in total ankle replacement (TAR) has produced contradictory results. It is important for a new surgeon to know what clinical and radiological parameters are considered reliable and ideal. It is clear that exposure to a high-volume center will increase the reliability of a new surgeon approaching TAR. Implant choice may be influenced by surgeon training, and the debate of mobile versus fix-bearing prosthesis is still open. Anterior versus lateral approach is still an open debate, with any hypothetical advantages given by the direct vision on the center of rotation to be proven...

REVIEW
Dawson Muir
National joint registries (NJRs) have been established in Northern Europe for over 20 years. Since then, many other countries have begun collecting and reporting national data for total ankle arthroplasty (TAA). With relatively small numbers implanted, a large variety of available designs, and with any long-term reports dominated by designer groups, TAA is ideally placed to benefit from large national or even pooled national registries. This article reviews the existing registry-based literature with respect to what is already known...

Optimal placement of correctly sized total ankle replacement (TAR) implants is elemental to prolonging the working life. The negative mechanical effects of implant malalignment are well characterized. There is one FDA-approved navigated TAR system with limited but encouraging outcomes data. Therefore, its value can be estimated only based on benefits other than a proven clinical outcomes improvement over conventional systems. These include unique preoperative planning through 3-dimensional templating and virtual surgery and the patient-specific cut guides, which also reduce overall instrumentation needed for the case...

In patients with a stiff ankle replacement, appropriate resection of scarred capsular structures, hypertrophic bone debridement, and careful release of tendons should be performed to achieve good outcomes. Appropriately sized and correctly implanted components are required to restore ankle function to as normal as possible. Although not proven, the better a total ankle replacement is balanced, the less likely scar and heterotopic bone formation will occur. In patients with a stiff and painful ankle replacement, a preoperative diagnostic workup is mandatory to understand the underlying pathologic process and plan appropriate treatment...

Periprosthetic infection after total ankle arthroplasty (TAA) is a serious complication, often requiring revision surgery, including revision arthroplasty, conversion to ankle arthrodesis, or even amputation. Risk factors for periprosthetic ankle infection include prior surgery at the site of infection, low functional preoperative score, diabetes, and wound healing problems. The clinical presentation of patients with periprosthetic ankle joint infection can be variable and dependent on infection manifestation: acute versus chronic...

Wound complications following total ankle replacement are common. A team approach, including plastic surgeons, should be utilized to manage these wound issues. The handling of the wound, from the index procedure, to a variety of flaps, can be utilized to provide a successful outcome following an ankle replacement.

REVIEW
Shu-Yuan Li, Mark S Myerson
Component subsidence has been found to be the top complication that leads to failure of the total ankle arthroplasty (TAA). The cause of subsidence formation is unclear, and is multifactorial. Talar subsidence is more frequently met than tibial subsidence, and the subsequent big bone loss is demanding to handle. As a revision treatment option, neither a revision TAA nor a salvage ankle and/or hindfoot arthrodesis procedure is easy to perform or can obtain a definite outcome. The Salto XT can be used to treat most of the TAA systems available for use in the United States with acceptable short-term outcomes...
