Total ankle arthroplasty (TAA) is an increasingly selected treatment for end-stage arthritis; however, failure and revision of the tibial talar components remains issue. Although multiple risk factors have been shown to contribute early component revision, no study has looked at combining such into a predictive model that could potentially decrease rates improve implant survival. This aimed develop TAA based on patient characteristics, patient-reported outcomes (PROs), immediate...

Background: Restoration of ankle alignment is important in total arthroplasty (TAA), but sagittal the talar component less studied than coronal sagittal. Little has been published on importance TAA. The radiographic inclination was hypothesized to be predictive TAA survival, subsidence, and functional outcomes. Methods: A retrospective review Vancouver End-Stage Ankle Arthritis Database performed all TAAs at a single center over 11 years utilizing 1 2 implants. Talar (TCI) angles were...

Background: Several benefits are published supporting patient-specific instrumentation (PSI) in total ankle arthroplasty (TAA). This study seeks to determine if TAA with PSI yields different radiographic outcomes vs standard (SI). Methods: Sixty-seven primary patients having surgery using or SI between 2013 and 2015 were retrospectively reviewed weightbearing radiographs at 6-12 weeks postsurgery. Radiographic parameters analyzed the medial distal tibia angle (MDTA), talar-tilt (TTA),...

Introduction: Patient-specific instrumentation (PSI) has been developed for total ankle arthroplasty (TAA), with proven benefits. One concern regarding PSI is the need more soft tissue dissection in order to accurately position guides, which theoretical disadvantage of increased osteolysis. The purpose our study compare incidence and magnitude osteolysis INFINITY Total Ankle System between standard referencing (SR) techniques. Methods: Sixty-seven patients who underwent primary TAA using...

The importance of the deltoid ligament in congruency and coupling tibiotalar joint is well known. current trend to repair it cases acute injuries context ankle fractures; however, there limited information on how should be reconstructed. objective this study was compare different types an fracture cadaveric model.Sixteen foot-ankle-distal tibia specimens were used. All samples prepared as a supination external rotation model. Axial load cyclic axial rotations applied every specimen using...

Category: Ankle Arthritis; Introduction/Purpose: Osteoarthritis (OA) of the tibiotalar joint is associated with a high degree morbidity, comparable to final stages renal and heart failure. The incidence OA in as 47.7 per 100,000 inhabitants, most whom will require surgical intervention improve their quality life. To date, there scarce literature on alignment Total Arthroplasty (TAA) its implications for patient-reported outcome measures (PROMs). Furthermore, no evidence has yet analyzed...

Category: Sports Introduction/Purpose: Achilles tenorrhaphy is one of the most common procedures performed in foot and ankle surgery, percutaneous techniques are safe achieve good outcomes. Over past 20 years, WALANT technique (Wide-awake local anesthesia no-tourniquet) has gained popularity due to its advantages: it does not depend on availability complex operating rooms or anesthetists, allows for intraoperative functional evaluation, presents lower costs, few complications have been...

Category: Ankle Arthritis Introduction/Purpose: Total ankle arthroplasty (TAA) and arthrodesis (AA) are standard treatment modalities for end-stage osteoarthritis. The total anatomical alignment is critical the longevity of components. Coronal sagittal malalignment results in altered joint mechanics reactive forces that result implant failure. Also, to our knowledge, tibial component sizing plane has been addressed knee literature, but not literature. Based on these parameters, we developed...

The purpose of this protocol was to adapt and validate the English version Short Musculoskeletal Function Assessment (SMFA) into Chilean Spanish according World Health Organisation guidelines. This is a cross-sectional study 897 surveys patients with non-traumatic surgical orthopaedic pathologies. We analysed internal consistency, validity, acceptability, including correlation short form 36 (SF-36) medical score. validation included 900 participants response rate 99,66%, excellent...

In end-stage ankle arthritis, little is known about the impact of concomitant knee pathology, including ipsilateral pain on total arthroplasty (TAA) outcomes. The aim this study was to determine prevalence preoperative in patients undergoing TAA and analyze its patient-reported functional outcome measures (PROMs). A retrospective review performed Vancouver End Stage Ankle Arthritis Database at a single institution. total, 114 were studied, with patient demographics collected preoperatively,...

Category: Ankle Arthritis Introduction/Purpose: Total ankle arthroplasty (TAA) and arthrodesis (AA) have been standard treatment modalities for end-stage osteoarthritis. Final implant position successful soft tissue balancing are key components to the longevity of total implants. Patient-specific instrumentation (PSI) has developed TAA, with proven cost effectiveness, accurate reproducible radiographic outcomes less operative time. However, one concern regarding PSI is need more dissection...

Category: Ankle Arthritis Introduction/Purpose: Axial alignment (rotation) in total ankle replacement has come to surgeons' attention recent publications. Unfortunately, most of the previously published data present information from non weight-bearing computed tomography (WBCT) scans or lack a correlation with patient-reported outcomes (PROs). To author's knowledge, axial is not completely understood its current form and relation PROs. Therefore, our objective propose standardization...

Methods: Cross-sectional where through 897 surveys patients with non-trauma surgical orthopaedic pathologies, internal consistency, validity acceptability were evaluated, including correlation short form 36 (SF-36) medical score. Results: preliminary...

Category: Midfoot/Forefoot; Bunion Introduction/Purpose: In Hallux Valgus (HV) surgery, the open technique has traditionally been used, which implies aggressive and extensive approaches, not without complications. The goal of surgical treatment HV is to correct anatomical deformity achieve a satisfactory long-term result, interrupting biomechanics weight-bearing function first metatarsophalangeal joint complex. recent years, use minimally invasive techniques (MIS) valid alternative due less...

The incidence OA as 47.7 per 100,000 habitants, whom most them will need surgical intervention to improve their quality life. Up date evidence supports use total ankle arthroplasty for its management. A great effort has been made elucidate factors failure prothesis, until now no attempt look...
