Interest in outpatient orthopedic surgery has been fueled by provider desire to control costs and development of rapid recovery protocols. Open reduction and internal fixation (ORIF) is a commonly elected treatment strategy for ankle fracture that may be performed in an outpatient setting. Lessons on cost-savings of the outpatient model in orthopedics can be learned in total joint replacement and spine surgery. Moreover, in properly selected patients, outpatient ORIF has been shown to be comparably safe. Reasons for admission of the surgically managed patient with ankle fractures, including concern for surgical delay and additional social factors, warrant further investigation...

Degenerative joint disease (DJD) of the ankle is a debilitating chronic disease associated with severe pain and dysfunction resulting in antalgic gait alteration. Little information is available about segmental foot and ankle motion distribution during gait in ankle osteoarthritis. The aim of the current study was to dynamically characterize segmental foot and ankle kinematics of patients with severe ankle arthrosis requiring total ankle replacement. This was a prospective study involving 36 (19 M, 17 F) adult patients with a clinical diagnosis of ankle arthrosis ("DJD" group) and 36 (23 M, 13 F) healthy subjects ("Control" group)...

Cartilage defects in adult patients do not heal well. Fresh osteochondral allograft (OCA) transplantation is based on mature, living, mechanically sound hyaline cartilage attached to a bone interface, which is brought into an osteochondral defect, where it becomes osseointegrated. According to current knowledge, intact hyaline cartilage tissue is immune privileged and does not, in contrast to bone, meniscus or ligaments, cause an immune reaction. The technique has the unique advantage of transplanting viable, mature and mechanically stable hyaline cartilage into the affected area...

BACKGROUND: Hallux rigidus is a common cause of foot pain in the elderly and has a negative impact on quality of life. Several operative treatment options are available for feet that are refractory to conservative treatment. Of these, total joint replacement and arthrodesis of the first metatarsophalangeal joint are the most commonly performed interventions. Nevertheless, it is still not known which intervention results in the best clinical outcome and the fewest complications. METHODS: PubMed/MEDLINE, Embase, and the Cochrane Library were systematically searched for studies assessing outcome with the American Orthopaedic Foot & Ankle Society-Hallux Metatarsophalangeal Interphalangeal (AOFAS-HMI) score, Foot Function Index (FFI), visual analog scale (VAS) for pain, or Short Form-36 (SF-36) in patients who underwent an arthrodesis or total joint replacement for the treatment of symptomatic hallux rigidus...

Treatment of large osseous defects remains a difficult surgical challenge. Autografts and allografts have been known to undergo late collapse, because these options are not specifically designed to withstand the high loads of the foot and ankle. The inability to achieve the correct shape for reconstruction further limits their application. Large osseous defects will result during salvage after failed Lapidus bunionectomy, explantation of failed total ankle replacements, and nonunion of Evans calcaneal osteotomy...

Inertial sensor systems are increasingly used in the assessment of persons with knee osteoarthritis (KOA) and total knee replacement (TKR). This systematic review aims to (1) investigate the application of inertial sensor systems and kinematics derived from these systems, and (2) assess if current assessment protocols consist of tasks which are, according to the International Classification of Functioning, Disability and Health (ICF) for KOA, relevant for persons with KOA and TKR. A search was conducted in six electronic databases (ACM, CINAHL, EMBASE, IEEE, PubMed, Web of Science) to include papers assessing the knee and one or more adjacent joints by means of inertial sensors in healthy persons or persons with KOA or TKR...

Chronic venous disease is caused by chronic venous insufficiency (CVI), which results in significant symptoms such as venous ulcers, ankle eczema, leg swelling, etc. Venous valve incompetence is a major cause of CVI. When the valves of veins in the leg become incompetent (i.e., do not close properly), blood is able to flow backwards (i.e., reflux), which results in blood pooling in the lower extremities, distal venous hypertension, and CVI. Current clinical therapies, such as surgical venous valve reconstruction and bioprosthetic venous valve replacement, are highly invasive and only moderately successful...

Given articular cartilage has a limited repair potential, untreated osteochondral lesions of the ankle can lead to debilitating symptoms and joint deterioration necessitating joint replacement. While a wide range of reparative and restorative surgical techniques have been developed to treat osteochondral lesions of the ankle, there is no consensus in the literature regarding which is the ideal treatment. Tissue engineering strategies, encompassing stem cells, somatic cells, biomaterials and stimulatory signals (biological and mechanical), have a potentially valuable role in the treatment of osteochondral lesions...

BACKGROUND: Although previous studies have compared radiological, pain, and function scores in kinematically aligned (KA) and mechanically aligned (MA) total knee arthroplasty (TKA), no previous studies have undertaken a three-dimensional (3D) gait analysis in these groups. This study compared kinematic and kinetic variables recorded during level walking in patients at least 2 years post-surgery who underwent an MA or KA procedure. METHODS: Utilizing a 9-camera motion analysis system, gait analysis was undertaken on 29 patients (MA = 15, KA = 14)...

BACKGROUND: There exists a high risk of post-operative complications with primary and revision total ankle replacement surgery. Delayed wound healing of the anterior incision is common. The reason for this is multi-factorial and, to date, most of the research has focused on predisposing factors involving the patients themselves. Only recently have researchers begun to look at the post-operative dressing as a possible consideration when trying to prevent incision wound healing complications...

Sloped walking is challenging for individuals with transtibial amputation (TTA) due to the functional loss of the ankle plantarflexors. Prostheses that actively generate ankle power may help to restore this lost function. The purpose of this study was to use musculoskeletal modeling and simulation to quantify the mechanical power delivered to body segments by passive and powered prostheses and the remaining muscles in the amputated and intact legs during sloped walking. We generated walking simulations from experimental kinematic and kinetic data on slopes of 0, ±3 deg and ±6 deg in eight people with a TTA using powered and passive prostheses and eight nonamputees...

Knee osteoarthritis (OA) causes pain, reduced muscular strength and stiffness of the affected joint. In response, the motor control mechanism is altered, potentially compromising stability during acts of daily living. Reduced walking stability can be quantified in terms of gait variability. This study therefore aimed to identify and quantify the effects of knee arthritis on gait variability. Fifty adults (25 males/25 females) with end-stage OA of the knee sufficiently symptomatic to require joint replacement, walked on a self-paced treadmill for 2min...
