Filter by:The objective is to study the joint kinematics of the prosthetic implant, in terms of translation, rotation, Range of motion and proprioception, in patients treated for prosthetic replacement of the ankle, quantitatively and under physiological load conditions.
Ankle osteoarthritis (AOA) is a typical long-term complication of an ankle injury. Pain during walking is the main symptom that limits walking distance. Non-surgical treatments could be used to decrease pain. The gold standard treatment for end-stage OA is definitive surgical ankle arthrodesis. The purpose of this study was to assess the effectiveness of a rigid ankle-foot orthosis (R-AFO) for walking pain in a population suffering from AOA.
Platelet-rich plasma (PRP) has been reported to be an effective treatment for knee osteoarthritis (OA). The application in ankle OA has rarely been investigated. The aim was to evaluate the efficacy and safety of a single intraarticular injection of PRP for the treatment of patients with ankle OA.
With IRB approval, a prospective single-cohort clinical trial will be performed to assess safety and efficacy of total biologic arthroplasty of the ankle. With informed consent, patients (n=10) who require tibio-talar arthroplasty based on physical examination and diagnostic imaging will be enrolled. Primary criteria for inclusion will be Grade IV changes in the articular cartilage of the tibial plafond and/or talar dome as determined by physical examination, diagnostic imaging and/or arthroscopy by the attending surgeon. Exclusion criteria include acute injury to any other part of the affected lower extremity or inability to comply with the protocol. After enrollment, patients will undergo standard ankle radiography and complete assessments (described below). Size-matched (standard clinical methodology) MOPSTM allografts (Musculoskeletal Transplant Foundation, Edison, NJ) from the same donor will be obtained to treat the entire tibiotalar joint. The affected joint will be treated with OCA transplants using our current technique and instrumentation. Osteochondral grafts including MOPSTM OCAs are regulated under U.S. Food and Drug Administration (FDA) section 361 of the Public Health Service Act and 21 Code of Federal Regulation 1271 that defines human cells, tissues or cellular or tissue based products (HCT/P). Patients will follow a managed post-operative rehabilitation protocol that is standard for those that have had an osteochondral allograft to their ankle. Range of motion and patient-reported outcome measures (PROMs) including VAS pain score, AOFAS, and PROMIS Mobility as well as complete radiographs (XR) of the affected ankle will be obtained prior to surgery and at 6 weeks, 3 months, 6 months, and 12 months after surgery to evaluate healing, function and evidence for arthrosis. MRIs for cartilage composition (12 months after surgery, and serum and urine biomarkers for treatment monitoring (preop, 6 and 12 months after surgery) will be performed. We will document all adverse events and complications, including joint or incision infection, graft failure, hardware failure, and arthrofibrosis. Patients with a VAS pain score >5 beyond 3 months postoperatively or clinical or diagnostic imaging evidence for nonunion or graft collapse will undergo MRI of the ankle to determine the appropriate clinical course of action. OCA survival will be determined based on maintenance of acceptable levels of pain (<2 VAS) and function and/or need for revision surgery or total ankle arthroplasty, fusion, or amputation.
Subtalar fusion is commonly performed in post-traumatic subtalar osteoarthritis, rheumatoid arthritis, posterior tibial tendon dysfunction, tarsal coalition and primary subtalar osteoarthritis. Patients with osteoarthritis or severe dysfunction involving both the ankle and the subtalar joint may benefit from an tibiotalocalcaneal fusion (TTC) or an ankle replacement and subtalar fusion. With the development of new prosthetic designs and of surgical techniques, total ankle replacements (TAR) became a reasonable alternative to fusion with functional and quality of life improvements. A gait analysis of patients that underwent TAR and simultaneous subtalar fusion allows to study with precision and reliability the ankle range of motion (ROM). On the contrary, in healthy subjects or in patients that underwent isolated TAR this is not possible because the ankle ROM is influenced by the ROM of the subtalar joint in such a way that it is not possible to analyze the two joints separately. Also, excluding the role of the subtalar joint, it is possible to accurately analyze and compare the consequences on ankle kinematics of two different prosthetic designs.
Many recent randomised multi-centre trials have used the AOS and the involvement of the French-speaking population is limited by the absence of a French version. The goal of our study was to develop a French version and validate the psychometric properties to assure equivalence to the English original.
To date, detailed analysis of movement patterns in orthopaedic conditions are mainly performed in research projects. Because these tests are time consuming, they are not feasible in clinical routine or in standard examinations. Novel technologies allow capturing detailed movement patters within a few minutes. The aim of this regional study is to compare aspects of movement tasks measured using a mobile gait analysis system to those measured using laboratory based systems and to determine aspects of gait patterns relevant for different orthopaedic conditions. Moreover, the researchers will investigate if these relevant aspects can be altered using surgical treatment or manual therapy.
The purpose of this study is to prospectively evaluate the functional outcome and patient satisfaction of total ankle replacement for tibio-talar osteoarthritis.
The purpose of this study is to compare the effects of intraarticular Botulinum Toxin A versus intraarticular hyaluronate plus rehabilitation exercise in patients with ankle osteoarthritis.
This is a randomized study to prospectively compare and evaluate the functional outcome and patient satisfaction of total ankle replacements for tibio-talar osteoarthritis using either the STAR or Salto-Talaris prothesis.
