BACKGROUND: Patients undergoing total or partial arthroscopic meniscectomy for treating traumatic meniscal tears are at greater risk of developing knee osteoarthritis (OA) due to increased mechanical load. The purpose of this study was to evaluate the effects of a valgus unloader brace in the medial meniscectomized knee joint during the gait cycle. METHODS: A three-dimensional finite element model of the knee joint was developed using the substructures segmented from magnetic resonance images...

Recent data suggest there are 2 factors associated with prolonged opioid use following arthroscopic meniscus surgery: opioid use prior to surgery and the presence of osteoarthritis. With heightened awareness and large-scale efforts to reduce perioperative opioid use, cessation prior to surgical interventions should be given strong consideration because this may result in meaningful reductions in postoperative prescriptions. In addition, counseling patients about opioid-induced hyperalgesia (where opioid medications can make pain worse and not better) in the preoperative period could be used in this population...

The goal of the practitioner managing a patient with knee osteoarthritis (OA) is to minimize pain and optimize their function. Several noninterventional (noninjectable) therapies are available for these individuals, each having varying levels of efficacy. An individualized approach to the patient is most beneficial in individuals with knee OA and the treatment plan the practitioner chooses should be based on this principle. The focus of this article is to provide an up-to-date overview of the treatment strategies available, evidence to support them, and in whom these treatments would be most appropriate...

Background Valgus knee braces have been reported to reduce the external knee adduction moment during walking. However, mechanistic investigations into the effects of valgus bracing on medial compartment contact forces using electromyogram-driven neuromusculoskeletal models are limited. Research question What are the immediate effects of valgus bracing on medial tibiofemoral contact forces and muscular loading of the tibiofemoral joint? Methods Sixteen (9 male) healthy adults (27.7 ± 4.4 years) performed 20 over-ground walking trials at self-selected speed both with and without an Ossür Unloader One® brace...

PURPOSE: The purpose of the present study was to investigate the effect of the unloader brace on medial compartment dynamic joint space (DJS) during gait, while simultaneously recording ground reaction force (GRF) in varus knee osteoarthritis (OA) patients using a highly accurate biplane radiography system which allowed continuous measurement of DJS from heel strike through the midstance phase of gait. The hypothesis was that DJS in the medial compartment would be greater with the unloader brace than without the brace during gait...

Braces and splints can immobilize and protect joints, reduce pain, decrease swelling, and facilitate healing of acute injuries. They are also used for injury prevention and chronic pain reduction, and to alter the function of a joint. The medial unloading (valgus) knee brace is an option for patients with medial knee osteoarthritis, but evidence of long-term benefit is limited. The patellar stabilizing brace helps maintain proper patellar alignment but has mixed results in treating patellofemoral pain syndrome...

BACKGROUND: Use of proprioceptive knee braces to control symptomology by altering neuromuscular control mechanisms has been shown in patellofemoral pain. Although their potential in patients with knee osteoarthritis is vast, little research has examined their efficacy. OBJECTIVES: This study examines the effect of a proprioceptive knee brace on lower limb kinematics and kinetics in healthy participants and in participants with OA. METHODS: Thirteen healthy participants were asked to perform a 10-cm step-down task with and without a proprioceptive brace...

PURPOSE OF THE STUDY Knee joint is the most common place where osteoarthritis may occur. A specific therapy is indicated to patients depending on the degree of disability and other signs. The available methods and their clinical value are regularly assessed in systematic reviews and meta-analysis of clinical studies. The evidence of working mechanism of the specific therapeutic intervention is another important part of evaluating its therapy effect. One of the possibilities of knee osteoarthritis conservative treatment is a functional prophylactic knee brace...

BACKGROUND: The use of an unloader brace is a non-surgical treatment option for patients with medial osteoarthritis (OA). However, many patients do not adhere to brace treatment, because of skin irritation due to the pads at the level of the joint space and bad fit. A new concept to unload the medial compartment of the knee is a foot ankle brace with a lever arm pressing the thigh in valgus. The aim of this prospective randomized trial was to examine the outcomes of patients with medial OA after treatment with a conventional knee unloader brace (Unloader One® ) and the new foot ankle orthosis (Agilium FreeStep® )...

PURPOSE: To investigate whether temporary postoperative compartment-unloading therapy after arthroscopic partial meniscectomy (APM)-with either knee braces or wedge insoles-leads to superior clinical outcome as compared to controls. This difference in clinical outcome was tested in the form of two knee scores, physical activity and general health outcome over the first postoperative year. METHODS: Sixty-three patients who underwent arthroscopic partial meniscectomy (APM) were randomized to one of the following three groups: 12 weeks postoperative knee compartment-unloading therapy with either a knee brace (brace group) or wedge insoles (insole group) or no specific postoperative therapy (control group)...

BACKGROUND: Knee osteoarthritis (KOA) is the most common form of arthritis with an estimated lifetime prevalence of 45%. The use of orthotic devices is a generally accepted conservative therapy in KOA. A new conservative treatment is an ankle-foot orthosis (AFO); however, studies on the biomechanical effects are limited. The aim of this study was to examine the acute effects of different orthotic devices (AFO, knee brace and wedged shoes) on (un)loading parameters in subjects with KOA...
