Ankle arthroplasty complication

BACKGROUND: According to the conventional postoperative procedure after total ankle arthroplasty (TAA) against end-stage osteoarthritis (OA) and rheumatoid arthritis (RA), mobilization and weight-bearing is currently started after completion of wound healing. Recently, early mobilization for dorsiflexion after TAA with modified antero-lateral approach was reported to be feasible and safe. To investigate the further possibility of expediting rehabilitation, this study evaluated the feasibility and safety of early full weight-bearing and gait exercise after cemented TAA utilizing a modified antero-lateral approach...

BACKGROUND: The aim of this study was to compare the efficacy and safety of patient-specific instrumentation (PSI) and conventional instrumentation (CI) for unicompartmental knee arthroplasty. Our hypothesis was that the PSI would be superior to CI in improving implant positioning and clinical function. METHODS: We searched electronic databases (PubMed, Web of Science, Embase, and Cochrane) to identify relevant studies published before July 1, 2023 that met our inclusion criteria...

INTRODUCTION: Ligament balancing is essential to the functional outcome of total knee arthroplasty (TKA). The optimal method of alignment remains a controversial issue. The primary objective was to compare the clinical outcomes of TKA between functional and adjusted mechanical alignment techniques. The secondary objectives were to compare bone resection, robotic alignment, and radiological assessment. MATERIALS AND METHODS: This was a retrospective case-control series comparing TKA performed with functional alignment (FA) and adjusted mechanical alignment (aMA)...

BACKGROUND: Prosthetic substitution of the talus presents a significant challenge to the foot and ankle surgeon. The shear and compressive forces on the talus and its tenuous blood supply lead to high rates of avascular necrosis and eventual talar collapse. The purpose of this systematic review is to evaluate whether total ankle total talus replacement (TATTR) leads to improved clinical and radiographic outcomes with appropriate safety metrics in patients with a history of avascular necrosis or significant trauma...

BACKGROUND: Total ankle arthroplasty (TAA) has higher complication and failure rates compared to other surgical joint replacement procedures despite technological advances. This study aimed to find the long-term survivability of the TAA procedure and identify the patient risk factors for failure with one of the largest cohorts of patients in the literature. METHODS: This retrospective cohort study involving cases between 2007 and 2018 analyzed patients who received an index primary TAA procedure in Korea...

Total ankle arthroplasty continues to gain popularity amongst surgeons and patients as an alternative to arthrodesis. Historically the designs of early implants were plagued with complications and frequently abandoned. Since that time the procedure and materials have undergone significant advancements in both surgical approach as well as design and function of the available implants.  In this study, 40 consecutive patients who received a semi-constrained prosthesis with a unique fixed bearing polyethylene insert were identified...

BACKGROUND: The INFINITY total ankle implant is a widely and successfully used option for total ankle arthroplasty. The purpose of this study is to assess the 2-year survivorship, complication rates, patient-reported outcomes, and radiologic findings of prospectively enrolled patients undergoing a fixed-bearing total ankle arthroplasty (TAA). This study sought to determine if factors such as traditional vs patient-specific instrumentation, preoperative degree of arthritis, deformity, or etiology of arthritis impact surgical or clinical outcomes...

Purpose : Cardiovascular disease (CVD) is a major risk factor for mortality in patients with osteoarthritis, and such comorbidities increase the risk of postoperative complications following total knee arthroplasty (TKA). Arteriosclerosis plays a major role in hemodynamic dysfunction and CVD; however, the postoperative changes in arteriosclerosis following TKA have not been evaluated. Therefore, we assessed the postoperative changes in arteriosclerosis using the cardio-ankle vascular index (CAVI) in patients undergoing TKA, and its relationships with preoperative patient characteristics...

Periprosthetic infection (PJI) after TAR is a serious complication, often requiring further surgery, including revision arthroplasty, conversion to ankle arthrodesis, or even amputation. This systematic review aims to summarize the current evidence on the management of TAR PJI and provide a comprehensive overview of this topic, especially from an epidemiologic point of view. Three different databases (PubMed, Scopus, and Web of Science) were searched for relevant articles, and further references were obtained by cross-referencing...

INTRODUCTION: While the efficacy of closed suction drains has been extensively studied in hip, knee, and shoulder surgery, it lacks scientific evidence in the foot and ankle domain, especially after total ankle arthroplasty (TAA). Thus, this study aims to compare the incidence of postoperative complications with and without the application of a closed suction drain following TAA. MATERIALS AND METHODS: A retrospective monocentric chart review of all patients who had undergone TAA with an anterior approach from January 2020 to March 2023 was performed...

BACKGROUND: Total ankle arthroplasty (TAA) is an effective treatment for various ankle pathologies, but some concern remains for the high associated complication and failure rates relative to major joint arthroplasty of the hip and knee. Patient body mass index (BMI) is a modifiable and potentially important preoperative variable when evaluating postoperative complications. The purpose of this study is to evaluate the effect of BMI, age and sex on the acute postoperative complication rate after TAA...

INTRODUCTION: There is still a lack of information on the role of Tranexamic acid (TXA) in total ankle arthroplasty (TAA). The purpose of this study is to comprehensively review, consolidate, and analyze findings from existing research on the effectiveness and safety of TXA in TAA. MATERIALS AND METHODS: The comprehensive literature review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) using PubMed, Embase, Web of Science, and Cochrane databases, for original, English-language studies investigating the efficacy and safety of TXA in TAA, through February 2023...

INTRODUCTION: Ankle osteoarthritis is more commonly posttraumatic. Consequently, dealing with hardware removal is quite frequent when performing a total ankle arthroplasty (TAA). The purpose of this study is to compare outcomes regarding either a staged or concurrent hardware removal when performing TAA. MATERIALS AND METHODS: 275 consecutive patients with TAA previously treated with internal fixation were retrospectively reviewed. Finally, 57 patients were enrolled based on exclusion criteria, and were differentiated into two groups considering the timing of hardware removal (staged-group A vs concurrent-group B) to compare: neurovascular and wound complications, time to recover full weight bearing, scar-tissue esthetic, and surgical time...
