BACKGROUND: There exists a high risk of post-operative complications with primary and revision total ankle replacement surgery. Delayed wound healing of the anterior incision is common. The reason for this is multi-factorial and, to date, most of the research has focused on predisposing factors involving the patients themselves. Only recently have researchers begun to look at the post-operative dressing as a possible consideration when trying to prevent incision wound healing complications...

Total ankle arthroplasty is a viable surgical technique for the treatment of end-stage degenerative joint disease. With continued advancement in prosthetic design, refined surgical techniques, and improved outcomes, the indications for total ankle replacement have expanded to include cases of increasing complexity. With meticulous preoperative planning and exacting execution, many frontal plane deformities and cases of avascular necrosis can now be successfully addressed at the time of prosthesis implantation or in a staged procedure...

Christopher L Reeves, Amber M Shane, Ryan Vazales
Much of the current literature suggests that total ankle replacement (TAR) is no longer an inferior or fringe treatment for advanced ankle arthritis compared with ankle fusion, but rather a viable option for recalcitrant arthritic ankle pathology in the correct patient population. In this article, current concepts associated with successful outcomes for TAR are discussed with an emphasis on ankle joint anatomy and biomechanics, preoperative planning and patient selection, understanding pathomechanics and soft tissue balancing, as well as the surgeon's learning curve...

Arthroscopic ankle arthrodesis provides an alternative to open techniques. Advancements in arthroscopic techniques and instrumentation have made the procedure easier to perform. Arthroscopic ankle arthrodesis has demonstrated faster rates of union, fewer complications, reduced postoperative pain, and shorter hospital stays. Sound surgical techniques, particularly with regard to joint preparation, are critical for success. Comorbidities such as increased body mass index, history of smoking, malalignment, and posttraumatic arthritis should be considered when contemplating arthroscopic ankle arthrodesis...

Background and purpose - Total ankle replacement (TAR) is gaining popularity for treatment of end-stage ankle arthritis. Large patient-centered outcome studies are, however, few. Here, we report data from the Swedish Ankle Registry. Patients and methods - We examined outcomes after primary TAR in patients from the Swedish Ankle Registry using PROMs (Patient Reported Outcome Measures; generic: EQ-5D and SF-36, region specific: SEFAS (Self-Reported Foot and Ankle Score), and a question on satisfaction). We included 241 patients registered with primary TAR between 2008 and 2016 and who completed PROMs preoperatively and postoperatively up to 24 months...

BACKGROUND: Total ankle replacement is associated to a high revision rate. To improve implant survival, the potential advantage of prostheses with fixed bearing compared to mobile bearing is unclear. The objective of this study was to test the hypothesis that fixed and mobile bearing prostheses are associated with different biomechanical quantities typically associated to implant failure. METHODS: With a validated finite element model, we compared three cases: a prosthesis with a fixed bearing, a prosthesis with a mobile bearing in a centered position, and a prosthesis with mobile bearing in an eccentric position...

BACKGROUND: Aseptic component loosening is a leading cause of revision for total ankle replacement. Different operative approaches for resecting the tibia and talus impact the bony support for the prostheses due to variations in both bone density and resection area, and may therefore impact loosening performance. METHODS: Computed tomography data from 116 subjects were obtained, and solid models of the talus and tibia were generated. Bone density, resection area, and bony support were measured on a series of flat resections for each subject, at multiple resection depths...

Total ankle replacement continues to become a more common treatment of end-stage ankle arthritis. A lateral approach total ankle implant system is an innovative approach for this treatment. We performed a retrospective review of 16 patients treated with lateral approach total ankle replacement. The implant was successful and retained in all cases during a follow-up period of 769 ± 221.3 days (25.3 ± 7.3 months). Initial satisfactory alignment was achieved in all cases. For patients in whom a frontal plane incongruent deformity was present preoperatively, a statistically significant correction was obtained (p = ...

Dislocation of the talus is a serious and extremely rare injury, with 86 cases reported in the published data in 20 years. The reference standard for case management involves replacement of the dislocated talus to restore the height and function of the tibiotalar joint. The risk of avascular necrosis remains very high, and the standard treatment in such cases is tibiotalar arthrodesis. We report the case of total dislocation of the talus, which was treated with the insertion of a custom total talar prosthesis affixed directly to the tibial cartilage at 6 months after injury...

As imaging techniques are ever-evolving, this article aims to provide a brief overview of the various modalities including their limitations. The ability of imaging for evaluation of implant osseo-integration will be addressed and also the role of imaging in assessing septic and aseptic loosening, with a particular focus on adverse tissue reactions, will be discussed. Specific features when imaging the big joints such as shoulder, hip, knee and ankle joint will also be outlined.Overall, a lack of standardisation and validity was noted and despite the gross variety of imaging modalities, there is no technique covering all aspects required for evaluation of implant fixation and septic and aseptic loosening...
