BACKGROUND: In patients with painful ankle arthrodesis, the surgical treatment is challenging, and may include takedown of ankle arthrodesis and conversion to a total ankle replacement (TAR). This procedure is technically demanding given the altered anatomy after arthrodesis. Few studies have evaluated TAR in the setting of prior arthrodesis. QUESTIONS/PURPOSES: (1) What intraoperative and perioperative complications were observed in patients who underwent conversion of an ankle arthrodesis to a TAR? (2) Was durable fixation achieved at short term, and what was the alignment of the components? (3) What subsequent surgical procedures were performed, including revisions? (4) What improvements were observed in pain, tibiotalar range of motion (ROM), and quality of life? METHODS: Between January 2007 and December 2014, 18 patients with a painful ankle arthrodesis underwent conversion to TAR at our tertiary referral center...

Adhesive shoulder capsulitis, or arthrofibrosis, describes a pathological process in which the body forms excessive scar tissue or adhesions across the glenohumeral joint, leading to pain, stiffness and dysfunction. It is a debilitating condition that can occur spontaneously (primary or idiopathic adhesive capsulitis) or following shoulder surgery or trauma (secondary adhesive capsulitis). Here, we review the pathophysiology of adhesive shoulder capsulitis, highlighting its clinical presentation, natural history, risk factors, pathoanatomy and pathogenesis...

OBJECTIVES: Sustained intra-articular delivery of pharmacological agents is an attractive modality but requires use of a safe carrier that would not induce cartilage damage or fibrosis. Collagen scaffolds are widely available and could be used intra-articularly, but no investigation has looked at the safety of collagen scaffolds within synovial joints. The aim of this study was to determine the safety of collagen scaffold implantation in a validated in vivo animal model of knee arthrofibrosis...

The purpose of this article is to review the etiology, economic burden, treatment strategies, and future research directions of arthrofibrosis after total knee arthroplasty (TKA). Arthrofibrosis is a debilitating postoperative complication of TKA. This condition is one of the leading causes of hospital readmission and a predominant reason for TKA failure. The prevalence of arthrofibrosis will increase as the annual incidence of TKA in the United States rises into the millions. Characterized by the excessive proliferation of scar tissue during an impaired wound healing response, the resulting stiffness of arthrofibrosis causes functional deficits in activities of daily living, such as walking, stair climbing, and standing from a chair...

PURPOSE: Inflammatory changes are suspected in the pathophysiology of arthrofibrosis formation and require early molecular examination. Here, we assessed the hypothesis that early inflammatory genes are related to arthrofibrosis by ascertaining gene expression during the early stages of contracture genesis in an animal model. METHODS: Joint trauma was incited surgically in a cohort of rabbits (n=36) knees followed by immobilization in a model of contracture. Six groups of 6 rabbits were sacrificed at multiple time points (0, 6, 12, 24, 72h and 2weeks)...

Rotation errors of the femoral component are held responsible for occurrences such as instability in flexion and midflexion, patellar maltracking, and arthrofibrosis following total knee arthroplasty. However, in many cases, the epicondylar axis cannot be reliably identified due to bone defects or metal artifacts on computed tomography, so alternative landmarks are necessary to evaluate the femoral component rotation. The current study sought to determine the relationship of the posterior cortical bone and the anterior cortical bone in relation to the epicondylar axis...

BACKGROUND: Total knee arthroplasty (TKA) is a highly successful surgery shown to improve quality of life. One of the more common known complications of TKA is early arthrofibrosis requiring manipulation under anesthesia (MUA). This investigation evaluates the incidence of arthrofibrosis before and after the implementation of an electronic sensor device used to assist with ligament balancing. METHODS: Six hundred ninety TKAs performed without sensor use were compared to a cohort of 252 TKAs performed with sensor usage...

A 53-year-old woman underwent arthroscopic ankle debridement for posttraumatic arthrofibrosis 2 years following a bimalleolar ankle fracture. Twelve months postarthroscopy, the patient returned to physical therapy with a 2-week history of pain and prominent swelling to her anterior ankle. Urgent follow-up was arranged with an orthopaedic surgeon, who ordered a radiograph and magnetic resonance imaging, which demonstrated a large heterogeneous mass. Doppler ultrasound was also ordered and confirmed the mass to be a pseudo-aneurysm of the anterior tibial artery...

INTRODUCTION: Tranexamic acid (TXA) is an antifibrinolytic agent that can be used to reduce blood loss in total knee arthroplasty (TKA) patients. Due to its thrombogenic properties, intravenous (IV) TXA is contraindicated in patients who have an increased risk of arterial or venous thrombosis. For such patients, intraarticular (IA) TXA may be a safe alternative. In this study, we compare: 1) complication rates; 2) intraoperative blood loss; and 3) need for transfusion in TKA patients who received IA TXA versus patients who used IV TXA...

BACKGROUND: In past decades, polyethylene wear was a major cause of failure in total knee arthroplasty (TKA). Polyethylene for use in arthroplasty has been vastly improved in recent years, with improved materials as well as manufacturing and sterilization processes. Testing has shown that infusion of vitamin E prevents oxidative degradation of polyethylene without remelting, allowing the material to maintain mechanical properties and wear resistance over time. The purpose of this study is to review the early result of patients undergoing primary TKA with vitamin E antioxidant-infused polyethylene inserts...

INTRODUCTION: Joint haemorrhage is the principal clinical manifestation of haemophilia frequently leading to advanced arthropathy and arthrofibrosis, resulting in severe disability. The degree and prevalence of arthrofibrosis in hemophilic arthropathy is more severe than in other forms of arthropathy. Expression of connective tissue growth factor (CTGF) has been linked to many fibrotic diseases, but has not been studied in the context of haemophilic arthropathy. AIM: We aim to compare synovial tissues histologically from haemophilia and osteoarthritis patients with advanced arthropathy in order to compare expression of proteins that are possibly aetiologic in the development of arthrofibrosis...

Implantable biomaterials supporting extended release of pharmacologic agents may permit localized intra-articular delivery of drugs that modulate the fibrotic response to injuries and surgery. Oligo[poly (ethylene glycol)] fumarate (OPF) is an attractive organic carrier, but its safety profile within synovial joints remains unclear. Here, we assessed the safety of OPF sponges using a validated in vivo model of knee arthrofibrosis. A cohort of 102 rabbits was divided into five groups: arthrotomy only (24), arthrotomy with OPF scaffold placement (24), surgically induced contracture (24), surgically induced contracture with OPF scaffold placement (24), and control without any surgical intervention (6)...

Arthroscopy of the ankle is used in the treatment and diagnosis of a spectrum of intra-articular pathology including soft tissue and osseous impingement, osteochondral lesions, arthrofibrosis, and synovitis. To help identify the correct pathology, imaging techniques are often used to aid the surgeon in diagnosing pathology and determining best treatment options. This article discusses the use of imaging in various ankle pathologies.
