“…This was an advantage of using the tights design rather than the traditional sleeve type design. To our knowledge, past studies on the benefits of soft and passive knee orthoses have been limited to subjective improvements and functional parameters (Mohd Sharif et al, 2017), and our study is the first to evaluate the metabolic benefits for the STS.…”

Various assistive devices like exoskeletons have been developed to aid the growing number of disabled people. Recent studies have started to explore using soft rather than rigid components to create lightweight and unobtrusive systems that can be more easily adopted by the general population. However, there is a tradeoff between compliance and power in these systems. We investigated the physiological benefits of using an inconspicuous, soft and passive assistive device which would avoid bulkiness, heaviness and user discomfort. We chose to assist the sit-to-stand (STS) maneuver because it is a common activity of daily living (ADL). STS is also recognized as one of the most challenging ADLs due to the high knee torque required, and the primary limiting factor is known to be knee extensor strength. Thus, the objective of this research was to develop and evaluate an unobtrusive knee assist wear called X-tights that could aid knee extension during STS using only soft and passive components. This was accomplished by routing elastic bands across the lower extremity. Thirty-one healthy participants performed STS tests with and without the X-tights, while metabolic cost and muscle activity were recorded. Metabolic power significantly decreased, by 3.2 ± 1.5% (P = 0.04), when utilizing the X-tights during the STS, while there was no statistically significant differences in muscle activity. The present work introduces a new soft and passive assist wear that can be worn inconspicuously under normal clothing, and we demonstrate promising results for the future development and integration of soft assistive technology for daily life.

Supplemental searches were performed to expand on key topics identified in the original literature search, i.e., subchondral bone pathology [1], knee sleeves [2][3][4][5][19][20][21], bone marrow lesions [22][23][24][25][26], clinical risk factors for knee OA progression [27][28][29][30][31][32][33], OA phenotypes [34], nonpharmacological treatments for OA [35][36][37][38][39][40][41][42][43], and clinical practice guidelines for OA management [44].…”

“…In patients without knee effusion, a snugly fitting elasticized knee sleeve can improve knee biomechanics [2,19], enable surefooted walking, and minimize lower extremity edema via mild compression (below the threshold for ischemia). Consistent with our findings, knee sleeve use is associated with improved activity scores and pain scores for patients with lower Kellgren-Lawrence grades (as for patient 2) [20], while corrective or realignment braces are more effective in moderate or severe OA (patient 1) [21].…”

“…Since 2015, patient 2 has walked independently with the use of bilateral elasticized knee sleeves at all times outside her home and most of the time within the home. Although physical therapists discouraged the use of knee sleeves because they might promote muscle weakness, patient 2 considered published evidence [ 2 – 5 ] and reasoned that wearing the sleeves would increase her muscle strength long-term by enabling her to walk more often. When walking without knee sleeves, she experiences numbness, transient sharp pains and a sensation of walking on an unhealed wound, especially at the right posterolateral tibial plateau where the subchondral fractures occurred.…”

Because the pathophysiology of knee osteoarthritis is poorly understood, optimal evidence-based clinical management is uncertain. Sibling comparison studies can help inform a clinical model to guide preventive care. We compared the 8-year clinical outcomes in 2 sisters with a family history of osteoarthritis, normal BMI, and absence of knee pain at baseline. Both patients had Kellgren–Lawrence grade 1 in the affected knee at the time of twisting knee injuries leading to osteoarthritis diagnoses at age 50 (patient 1) and 51 (patient 2). Patient 1 developed a chronic right knee effusion, and progressed to Kellgren–Lawrence grade 3 bilaterally by the time she had a right total knee replacement at age 58. Patient 2 had subchondral fractures of the right knee with transient effusion, which healed after 1 year of partial weight-bearing with crutches and subsequent daily use of knee sleeves. Patient 2 had Kellgren–Lawrence grade 0 bilaterally upon surveillance imaging at age 58. The terms “osteoarthritis and knee and diagnostic imaging and subchondral bone and pathophysiology” were searched in the PubMed database to identify original research articles to inform a clinical model consistent with the patients’ outcomes. A fluid model of osteoarthritis was the best explanatory model for the discordant clinical trajectories of the age-matched siblings. Patient recommendations are presented based on these findings.

BackgroundThe anterior cruciate ligament (ACL) is one of the most important structures maintaining stability of knee joints, and the proprioception of the ACL plays a key role in it. If the ACL is injured in the unilateral knee joint, it changes nerve electrophysiology, morphology, and quantity of the proprioceptors in the bilateral ACL. The aim of this study was to explore the proprioceptive changes in the bilateral knee joints following unilateral ACL injury, and to provide a theoretical foundation and ideas for clinical treatment.Material/MethodsNine normal cynomolgus monkeys were chosen and used to developed a model of unilateral ACL injury, and 3 monkeys without modeling were used as blank control. At the 4th, 8th, and 12th weeks, the changes in ACL nerves were inspected using electrophysiology [somatosensory evoked potentials (SEPs) and motor nerve conduction velocity (MCV)], and the changes of morphology and quantity of the proprioceptors in ACL were observed and measured under gold chloride staining.ResultsOn the injured and contralateral knee joints, the incubations were extended and the amplitudes were decreased over time. In addition, with the extension of time, the total number of proprioceptors in the ACL decreased, and the variable number of proprioceptors in the ACL increased.ConclusionsACL injury leads to attenuation of proprioception on the injured side, and also leads to the attenuation of proprioception on the contralateral side, and there is a tendency could get worse over time.
