Introduction Osteoarthritis of the knee affects millions of people. Elastic knee sleeves aim at relieving symptoms. While symptomatic improvements have been demonstrated as a consequence of elastic knee sleeves, evidence for biomechanical alterations only exists for the sagittal plane. We therefore asked what effect an elastic knee sleeve would have on frontal plane gait biomechanics. Methods 18 subjects (8 women, 10 men) with osteoarthritis of the medial tibiofemoral joint walked over ground with and without an elastic knee sleeve. Kinematics and forces were recorded and joint moments were calculated using an inverse dynamics approach. Conditions with sleeve and without sleeve were compared with paired t-Tests. Results With the sleeve, knee adduction angle at ground contact was reduced by 1.9±2.1°(P = 0.006). Peak knee adduction was reduced by 1.5±1.6°(P = 0.004). The first peak knee adduction moment and positive knee adduction impulse were decreased by 10.1% (0.74±0.9 Nm•kg-1; P = 0.002) and 12.9% (0.28±0.3 Nm•s•kg-1; P < 0.004), respectively. Conclusion Our study provides evidence that wearing an elastic knee sleeve during walking can reduce knee adduction angles, moments and impulse in subjects with knee osteoarthritis. As a higher knee adduction moment has previously been identified as a risk factor for disease progression in patients with medial knee osteoarthritis, we speculate that wearing a knee sleeve may be beneficial for this specific subgroup.

Osteoarthritis (OA) is most common joint disorder worldwide. It is second most common frequent joint disease with a prevalence rate of 22% to 39% in India. It affects women more than men. Knee OA is affect balance, muscle power, gait parameters. Main function of cane are to increase the support base, improve balance, and share the body weight load with the upper limb, which is achieved by directly applying force to the handle of the cane. Knee brace is give joint stability, less ending muscle co-contraction, improving proprioception, decreasing the magnitude of load on the knee through improvement in Malalignment and distribution of load across the knee. Aim is to compare the effect of no assistive device, cane and knee brace on balance in adults with knee OA by using time up and go test. Study included 52 patients individual with case of OA of knee between the age of 40 to 60 years. Patients were observed 3 days by randomly selected groups. Balance was measured by TUG in Group A (no device), Group B (cane) and Group C (brace) then statistical analysis was done. In statistical analysis, analysis of outcome measure of TUG was done by nonparametric test. So between groups Kruskal Wallis test was done. There was statistically significant difference found in TUG in between Groups analysis and it is concluded the knee brace is effectiveness in balance and gait velocity with knee OA patients.

Knee injury is one of the major problems in sports medicine, and the use of prophylactic knee braces is an attempt to reduce the occurrence and/or severity of injuries to the knee joint ligament(s) without inhibiting knee mobility. The aim of the present study was to examine the effect of one recently designed prophylactic knee brace and two neoprene knee sleeves upon performance of healthy athletes. Thirty-one healthy male athletes (age = 21.261.5) volunteered as participants to examine the effect of prophylactic knee brace/sleeves on performance using isokinetic and functional tests. All subjects were tested in four conditions in a random order: 1. nonbraced (control) 2. using a neoprene knee sleeve 3. using a knee sleeve with four bilateral metal supports and 4. using a prophylactic knee brace. The study design was a crossover, randomized, controlled trial. Subjects completed single leg vertical jump, cross-over hop, and the isokinetic knee flexion and extension (at 60, 180, 300u/sec). Data were collected from the above tests and analyzed for jump height, cross-over hop distance, peak torque to body weight ratio and average power, respectively. Comparisons of these variables in the four testing conditions revealed no statistically significant difference (p.0.05). The selected prophylactic brace/sleeves did not significantly inhibit athletic performance which might verify that their structure and design have caused no complication in the normal function of the knee joint. Moreover, it could be speculated that, if the brace or the sleeves had any limiting effect, our young healthy athletic subjects were well able to generate a mean peak torque large enough to overcome this possible restriction. Further studies are suggested to investigate the long term effect of these prophylactic knee brace and sleeves as well as their possible effect on the adjacent joints to the knee.
Efficacy of Knee Braces and Foot Orthoses in Conservative Management of Knee Osteoarthritis
American Journal of Physical Medicine & Rehabilitation, 2011
Raja K, Dewan N: Efficacy of knee braces and foot orthoses in conservative management of knee osteoarthritis: a systematic review. Am J Phys Med Rehabil 2011;90:247Y262. A systematic analysis was conducted on the effectiveness of knee braces and foot orthoses in conservative management of knee osteoarthritis. The methodologic quality of the randomized clinical trials, controlled clinical trials, and observational studies were systematically reviewed using the Structured Effectiveness Quality Evaluation Scale. Twenty-five studies met the inclusion criteria. The orthoses used in the studies included Generation II osteoarthritis knee brace, valgus knee braces, functional off-loading knee braces, knee sleeves, lateral-wedged insoles with subtalar strapping, medial-wedged insoles, and specialized footwear. Results suggest that knee braces and foot orthoses are effective in decreasing pain, joint stiffness, and drug dosage. They also improve proprioception, balance, Kellgren/ Lawrence grading, and physical function scores in subjects with varus and valgus knee osteoarthritis. Knee braces and foot orthoses could be cautiously considered as conservative management for relief of pain and stiffness and improving physical function for persons with knee osteoarthritis. The conclusions of this review are limited by methodologic considerations like poor quality of trials and heterogeneity of interventions.

Introduction Gait modification is frequently used as conservative management in knee osteoarthritis (OA). Knee orthoses, such as knee sleeves and unloader knee braces, are nonpharmacological treatment for gait modification in symptomatic knee OA. Previous studies lack systematic investigation of biomechanical effect and functional capacity, particularly walking capacity. This study investigated effects of knee orthoses on biomechanics and walking capacity in patients with knee OA. Materials and methods A literature search was conducted in PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Physiotherapy Evidence Database (PEDro), and Cochrane Central Register of Controlled Trials (CENTRAL) according to inclusion criteria from 1966 to May 2013. Trials investigating the effects of knee orthoses on biomechanics or walking capacity were collected. Effect size was calculated exclusively according to biomechanical and walking capacity variables reported over 5 publications. Narrative analysis of the studies was performed. Results The database search provided a total of 1681 citations with 19 studies that investigated effect of neoprene sleeves and unloader knee braces, and satisfied the inclusion criteria. Of these, one was a randomized controlled trial; the other 18 studies were within-subjects, repeated measures designs. Study results indicated unloader knee braces could decrease knee adduction moment, particularly the 2 nd peak during walking, compared to controls. However, unloader knee braces did not improve walking endurance, and effects on walking speed differed between studies. Discussion Load-reduction effects of unloader braces used while walking coincide with clinical observations of pain reduction. Our results suggest the mechanism of immediate decrease in knee pain may be due to decreased adduction moment especially at the 2 nd peak, though this may not affect walking capacity. The conclusions of this review are limited by methodological considerations; therefore, high-quality randomized controlled trials concerning bracing biomechanical changes and functional capacity for knee OA are still necessary.
The effect of a knee brace in dynamic motion—An instrumented gait analysis
PLOS ONE, 2020
Background Osteoarthritis (OA) is a common problem in the older population. To reduce pain and stress in the affected knee joint compartment, a functional knee brace is often prescribed by physicians to protect it from high loads. Objectives An instrumented gait analysis should evaluate how the 4-point knee orthosis for varus or valgus load relief (M.4s OA) changes the kinematics of the knee, especially in the frontal plane. Methods 17 healthy participants took part and were analyzed with an inertial sensor system (MyoMotion) giving continuous, objective information on the anatomical angles. The measurements were made both without wearing a knee brace and with the brace in different settings. Results The results show a significant reduction in the maximum knee abduction and raised knee adduction. The knee brace, with a strong adjustment in varus or valgus orientation, caused a shift of maximum ab-/adduction in the proposed direction in 69% and 75% of the dynamic tests, respectively. The knee motion in the frontal plane shows individual movement patterns.
Knee Bracing: Effects on Proprioception
Archives of Physical Medicine and Rehabilitation, 1996
Objective: To, examine the effects of a knee sleeve type brace on the proprioceptive ability of subjects with normal knees during a dynamic tracking task. Design: A 2 x 2 Latin square cross over design; in each Latin square, subjects were matched for age and gender. Setting: An institution focused on clinical education. Participants: Twenty subjects with no musculoskeletal or neurological conditions. Intervention: Each subject performed a tracking task on a Kin-Corn dynamometer. Angle and force data from the Kin-Com and angle data from an electrogoniometer were sampled at 100Hz using a data acquisition program on a PC computer. The subjects were blindfolded and the limb attached to the Kin-Com was moved passively by the dynamometer. Subjects were instructed to follow the movement as closely as possible with the other limb (the tracking limb). Subject performed two trials, one without knee bracing and another that involved the application of a brace to the tracking limb. Outcome Measure: The magnitude of the error in tracking was established by taking the difference of the active and passively moving l~mbs and calculating the root mean square (RMS) of the difference. Results: The findings showed that there was an improvement of 11% in tracking when subjects wore the knee brace (p < .05). Conclusion: Alterations in proprioception as a result of bracing may be partly responsible for the improvement in knee injury statistics reported in some studies.
