BACKGROUND: Over the past decade, total ankle arthroplasty (TAA) has become a mainstay in the treatment of end-stage ankle arthritis. Currently in its fourth generation, the Scandanavian Total Ankle Replacement (STAR) is the only 3-piece mobile bearing ankle prosthesis available in the United States. Our current study reports implant survivorship at 15 years and patient outcomes for a subset of these survivors available for study. METHODS: Eighty-four TAAs were performed between 1998 and 2000...

OBJECTIVES: Limb lengthening after total knee arthroplasty (TKA) has been reported in some cases, all of which were evaluated using 2-dimensional images. To our knowledge, no case has been evaluated using 3-dimensional (3D) images. We investigated 3D limb lengthening after TKA. METHODS: We simulated 100 varus knees using 3D templating software. Virtual TKA was performed to maintain the original joint line by conducting a measured-resection technique. We examined the relationships of 3D distance between the femoral head center and ankle center before and after TKA, degree of hip-knee-ankle angle (HKA) improvement, and degree of flexion contracture angle improvement...

If operative treatment is opted for grade 3 and 4 osteoarthritis of the first metatarsophalangeal joint, arthrodesis is considered the standard of care. However, if preservation of joint mobility is preferred, implant arthroplasty could be favored. Previous studies have suggested hemiarthroplasty might result in less pain, better function, and greater patient satisfaction compared with arthrodesis. However, these studies only evaluated short-term results (range 2.2 to 6.6 years). The aim of our study was to determine whether patients treated with hemiarthroplasty would show better postoperative outcomes compared with those treated with arthrodesis after ≥5 years after surgery...

BACKGROUND: Osteochondral allograft (OCA) transplantation is a useful alternative for treatment of posttraumatic ankle arthritis in young patients but has a relatively high failure rate and further procedures are often required. The purpose of this study was to evaluate outcomes of patients who underwent revision OCA transplantation of the ankle after failed primary OCA transplantation. METHODS: Twenty patients underwent revision OCA transplantation of the ankle between 1988 and 2015...

Post-traumatic arthritis (PTA) is characterized by the deterioration of articular cartilage temporally associated with an articular injury. With a paucity of literature comparing joint preservation techniques, we performed a systematic review of the literature intending to describe and summarize the results of ankle distraction arthroplasty as it compares with studies on tibio-talar microfracture, allograft, and autograft for ankle joint preservation in the post-traumatic population under 50 years of age. Research databases were searched and abstracts screened for relevance on our topic of interest...

BACKGROUND: The purpose of our study was to identify factors affecting posterior cruciate ligament (PCL) tightness during cruciate-retaining total knee arthroplasty. METHODS: A total of 225 varus osteoarthritic knees that underwent cruciate-retaining total knee arthroplasty were included in this study. When the flexion gap was tighter than the extension gap after all bone resection and the lift-off sign was positive during surgery, the PCL was released. The association between PCL release and potential risk factors, such as age, gender, body mass index, preoperative range of motion, anterior cruciate ligament status, preoperative hip-knee-ankle angle (HKA), decrease in posterior condylar offset, and also change in tibial posterior slope angle (TPSA) from preoperative to postoperative measurement, was evaluated by univariate and multivariate logistic regression analyses...

PURPOSE: This study aimed to assess radiological changes of the ankle joint, subtalar joint and foot following the correction of varus deformity of the knee with total knee arthroplasty (TKA). It was hypothesized that following the correction of varus deformity by TKA, compensatory reactions would occur at the subtalar joint in accordance with the extent of the correction. METHODS: For this prospective study, 375 knees of patients who underwent TKA between 2011 and 2012 were enrolled...

BACKGROUND: Few studies have outlined the outcomes and complications in Asians undergoing total ankle arthroplasty. This study reports the functional, radiological outcomes and satisfaction rates in our Asian population. METHODS: Patients who underwent primary total ankle arthroplasty from 2007 to 2013 were recruited. Outcomes evaluated were the AOFAS Ankle-Hindfoot Score (AHS), Visual Analogue Scale(VAS), and the Short Form 36 (SF-36)questionnaire. Outcome scores were collected prospectively up to 2 years...

INTRODUCTION: This study asked whether differences in coronal alignment after total knee arthroplasty (TKA) affect the load distribution on the tibial plateau. The aim of this study was to investigate the correlation between coronal alignment and the load distribution on the tibial plateau after TKA, using three-dimensional multi-detector-row-computed tomography (3D-MDCT). MATERIALS AND METHODS: In this study, we performed 84 cementless TKA with porous tantalum modular tibial component (PTMT) and divided into three groups based on post-operative hip-knee-ankle (HKA) angle: varus alignment group (n = 22), (176° ≧) neutral alignment group (n = 45), (180° ± 3°), and valgus alignment group (n = 17) (184° ≦)...

INTRODUCTION: To determine the effort required to provide a service, the United States Medicare uses Relative Value Units (RVUs). Consequently, higher RVUs are assigned to the procedures or services that require more effort, which ultimately means the physician will be properly compensated for the additional effort required. In total ankle arthroplasty (TAA), revision cases usually are more technically challenging and require more effort than primary TAA. Therefore, the purpose of this study was to compare the: 1) RVUs; 2) length-of-surgery; 3) RVU per unit of time between primary and revision total ankle arthroplasty; and 4) the individualized idealized surgeon annual cost difference analysis...

BACKGROUND: Sitting radiographs have been used as a pre-operative tool to plan patient-specific total hip arthroplasty (THA) component position that would improve hip stability. Previous work has demonstrated that spinal mobility may impact functional acetabular position when seated. We sought to determine whether patients who dislocate following THA have different sitting spinopelvic alignment or acetabular component orientation compared to patients who did not dislocate. METHODS: A consecutive series of 1000 patients underwent post-operative low-dose biplanar spine-to-ankle lateral radiographs in standing and sitting positions 1 year following THA...

Total ankle arthroplasty has become an increasingly used alternative to ankle arthrodesis for the treatment of end-stage ankle arthritis. However, despite progressive technological advances and the advent of multiple commercial implant systems, some concern remains for the relatively high complication and failure rates. The objective of the present investigation was to perform a systematic review of the incidence of complications in obese patients undergoing total ankle arthroplasty. We performed a review of electronic databases with the inclusion criteria of retrospective case series, retrospective clinical cohort analyses, and prospective clinical trials with ≥15 total participants, a mean follow-up period of ≥12 months, ≥1 defined cohort with a body mass index of ≥30 kg/m2, and a reported incidence rate of complications requiring revisional surgery at the final follow-up point...

Periprosthetic joint infection (PJI) after total ankle arthroplasty (TAA) is a devastating complication that often results in explantation to resolve the infection. The purpose of the present investigation was to determine the patient-related risk factors for PJI after TAA. A national insurance database was queried for patients undergoing TAA using the Current Procedural Terminology and International Classification of Diseases, ninth revision, procedure codes from 2005 to 2012. Patients undergoing TAA with concomitant fusion procedures or more complex forefoot procedures were excluded...

: Liver transplantation is one of the treatments for haemophilic patients having severe liver cirrhosis who are infected with the hepatitis C virus. Patients with haemophilia can develop arthroplasty requiring surgical intervention, and the surgical outcomes of patients undergoing such procedures after liver transplant has not been reported. Treatment for arthropathy is important for improving the quality of life for patients who survive after liver transplantation. We report the first case of ankle arthroscopic arthrodesis in a patient with haemophilia B after undergoing living donor liver transplantation...

Background: In total knee arthroplasty (TKA) for valgus knees, the decision to use a constrained implant is often made intraoperatively depending on the extent of soft tissue releases performed and residual soft tissue imbalance. The purpose of this study is to determine if preoperative radiographic criteria of valgus knees can predict the extent of soft tissue releases required and the level of constraint needed to balance the knee during TKA. Methods: A single surgeon's 807 consecutive TKA standing hip-knee-ankle radiographs from 2007-2012 were analyzed...

PURPOSE: The primary aim of the study was to examine stability and alignment after total knee arthroplasty (TKA) using patient-specific instrumentation (PSI) and conventional instrumentation (CI). The hypothesis was that stability and alignment would be better using PSI than CI, 12 months postoperatively. The secondary aim included the evaluation of clinical outcomes after TKA. METHODS: In this prospective randomized controlled trial, 42 patients with knee osteoarthritis received a Genesis II PS prosthesis with either PSI or CI...
