Individuals with post-stroke hemiparesis often have difficulty standing out of a chair. One way to potentially improve sit-to-stand is to provide knee extension assistance using a powered knee exoskeleton. An exoskeleton providing unilateral, partial assistance during sit-to-stand would need to be torque-controllable. There are no knee exoskeletons on the market suitable for conducting experiments assisting stroke patients with sit-to-stand, so to enable such experiments a research device was developed. The purpose of this report is to present the design of a novel knee exoskeleton actuator that uses a fiberglass leaf spring in series to improve torque-controllability, and present a characterization of the actuator performance...

Knee-ankle-foot orthoses (KAFOs) are full leg braces for individuals with knee extensor weakness, designed to support the person during weight bearing activities by preventing knee flexion. KAFOs typically result in an unnatural gait pattern and are primarily used for level ground walking. A novel variable resistance orthotic knee joint, the Ottawalk-Variable Speed (OWVS), was designed to address these limitations. This paper presents a pilot test to evaluate the OWVS functional performance during walking and stair descent...

BACKGROUND: Despite American Academy of Orthopaedic Surgeons Clinical Practice Guidelines (CPGs) related to the non-arthroplasty management of osteoarthritis (OA) of the knee, non-recommended treatments remain in common use. We sought to determine the costs associated with non-arthroplasty management of knee OA in the year prior to total knee arthroplasty (TKA) and stratify them by CPG recommendation status. METHODS: The Humana database was reviewed from 2007 to 2015 for primary TKA patients...

PURPOSE: We prospectively investigated the foot abduction characteristics following Steenbeek foot abduction brace (SFAB) use in corrected clubfeet. The foot abduction achievable in SFAB with knee flexion and extension was calculated to find the effectiveness and stretch exerted by it. METHODS: Only children with corrected idiopathic clubfeet using SFAB for greater than 3 months were enrolled. The foot abduction with and without brace in knee extended and flexed positions was measured...

INTRODUCTION: Disengagement of polyethylene insert used in total knee arthroplasty is a rare but serious complication. Still rarer is disengagement because of failure of tibial insert locking mechanism. We report a previously unpublished complication of polyethylene insert locking mechanism failure in a 10-months-old posterior stabilized total knee arthroplasty in a 70-year-old woman with osteoarthritis for whom Attune (Depuy) knee implant was used. CASE PRESENTATION: A 70-year-old female underwent (Attune, Depuy) primary bilateral posterior stabilised total knee arthroplasty in a private hospital...

REVIEW
Johann Beaudreuil
Orthoses for osteoarthritis represent splints, taping, sleeves, unloading knee braces and insoles. This review of the effectiveness of these orthoses involved a search for articles published up to 2015 in MEDLINE via PubMed, with a focus on Osteoarthritis Research Society International, American College of Rheumatology and European League Against Rheumatology international recommendations. Evidence for splinting effectiveness in patients with thumb-base osteoarthritis is now provided. Splints for thumb-base osteoarthritis decrease pain and functional disability...

REVIEW
Gabriel T Mindler, Christof Radler, Rudolf Ganger
PURPOSE: Instability of the knee is a common finding in patients with congenital limb deficiency. The instability can be attributed to soft tissue abnormalities, frontal, sagittal or rotational deformity of the lower limb and bony dysplasia of the patella or of the femoral condyles. In most of the cases, these pathomorphologic changes stay asymptomatic in daily activity. However, instability can appear during deformity correction and bone-lengthening procedures, leading to flexion contracture or subluxation of the knee...

PURPOSE: After reconstructing a torn ACL with a soft tissue allograft, the long-term healing process of graft maturation following the short-term healing process of graft incorporation into the bone tunnels might lead to recurring instability and concomitant decreases in the activity level, function, and patient satisfaction. Relying on roentgen stereophotogrammetric analysis (RSA), the primary purpose was to determine whether anterior laxity increased and whether patient-reported outcomes declined between 1 and 7 years for a particular graft construct, surgical technique, and rehabilitation programme...

The use of a pneumatic unloader brace has been shown in pilot studies to decrease pain and increase muscle strength in patients with knee osteoarthritis (OA). Therefore, we analyzed patients who had knee OA, and either received a pneumatic unloader brace and conventional treatment or conventional treatment alone. Specifically, we assessed: (1) use of pain relieving injections; (2) opioid consumption; and (3) the eventual need for total knee arthroplasty (TKA) in the above-mentioned cohort. We performed an analysis of a longitudinally maintained database of patients from a prospective, randomized, single center study...

BACKGROUND: Intra-articular hyaluronic acid (HA) injection is an intermediate option between analgesics and knee joint replacement in patients with osteoarthritis (OA). Our objective was to test whether image-guided HA injections may improve knee OA outcomes after 6 months of treatment independent of potential covariates. METHODS: This is a retrospective case series with multivariate outcome-based analysis of 207 consecutive adult patients with mild to severe knee OA treated at a single out-patient clinic employing fluoroscopy-guided HA injections...

Blount's disease is commonly attributed to an intrinsic, idiopathic defect in the posteromedial proximal tibial physis resulting in progressive bowing of the leg, intoeing, and lateral knee thrust. Treatment has historically included bracing, physeal stapling, or corrective osteotomy, and was determined primarily by age at presentation. As we feel the pathology is not necessarily age dependent, we have elected to use the technique of guided growth using a lateral tension band plate to correct limb alignment as a first-line treatment in all patients presenting to our clinic as long as they had growth remaining and no evidence of a physeal bar...
