“…However, the researchers concluded, that further well-designed experimental studies are indicated in this regard before any clinical implications about the causal role of muscle in osteoarthritis dysfunction can be validated. Muscle steadiness, expressed as the coefficient of variance [%] and peak power frequency [Hz] elicited during maximal voluntary knee extensor torque generating tests, which seems to be a distinctive muscle attribute related to its strength and self-reported function in cases with knee osteoarthritis, may yet be worth examining further in the future even if findings here are presently unconvincing [68].…”

Background: Knee joint osteoarthritis is a highly disabling disease with no distinct cause that persists unabated despite decades of research. Among the various possible causes and factors that influence the progression of the disease other than age and trauma may be various forms of muscle dysfunction, especially among the key knee extensor muscle group known as the quadriceps femoris. Aim: This narrative review strove to examine some pertinent past and recent 2022 research highlights in this respect and to offer possible research recommendations in this regard. Methods: To achieve the review aims, the PUBMED data base and others housing reports aligned with this topic was searched using the key words knee osteoarthritis and quadriceps/knee extensor muscles. Pertinent 2022 and related data were carefully examined and the study researchers’ approaches, conclusions, and recommendations were duly recorded. Results: Many diverse studies within the desired topical theme prevail, rendering it challenging to discern or extract any meaningful trend or conceptuality sound deterministic theory of causation or pathogenic osteoarthritis insights. Even in the realm where multiple publications are available on a single theme, conclusions and design approaches remain inconsistent and of possible moderate quality at best. Conclusion: Efforts to examine and intervene to avert one or more manifestations of quadriceps muscle dysfunction may prove to be highly important in the realm of favorably influencing or minimizing excess osteoarthritis knee joint dysfunction, regardless of whether knee extensor muscle dysfunction is a reactive, rather than a causative factor, but requires a more profound evidence base.

Background The knee adduction moment(KAM) of both lower limbs in patients with unilateral knee osteoarthritis(KOA) exhibits asymmetry during walking, but the factors influencing this asymmetry remain unclear. This study aimed to explore the influencing factors of KAM asymmetry in patients with unilateral KOA. Methods A total of 148 patients with unilateral medial compartment KOA were selected for this retrospective study, and general data such as gender, age, and duration of disease were collected. The hip-knee-ankle (HKA) angle, degree of pain, and knee-extension muscle strength on the affected side were assessed through radiographic outcomes, the visual analog scale(VAS), and the Biodex isokinetic system. The peak KAM of both lower limbs was analyzed using a BTS motion-capture system and force platform. The asymmetry index(ASI) of KAM was calculated, and the patients were further categorized into the KAM symmetry group(ASI value ≤ 10%) and the KAM asymmetry group(ASI value>10%).Binary logistic regression analysis was employed to analyze the factors influencing the asymmetry of KAM. Results 90 patients were categorized into the KAM asymmetry group, representing 60.8% of the cohort. A significant difference in the ASI value of KAM was observed between the two groups. Correlation analysis identified nine factors, including sex, age, and BMI, that were positively correlated with the ASI value of KAM. In contrast, knee-extension muscle strength and per-capita monthly household income were negatively correlated with the ASI value of KAM. Regression analysis revealed that being female(OR = 1.752), older age(OR = 2.472), increased BMI(OR = 1.535), larger varus angle(OR = 3.965), higher VAS score(OR = 2.617), Kellgren-Lawrence(K-L) grade IV(OR = 4.474), history of knee joint trauma(OR = 5.684), and living in a rural location(OR = 1.554) increased the risk of KAM asymmetry. Conversely, increased knee-extension muscle strength(OR = 0.758) and a per-capita monthly household income of 3000 ~ 6000 yuan(OR = 0.814) decreased the risk of KAM asymmetry. Conclusion Female gender, older age, increased BMI, larger varus angle, higher VAS score, K-L grade IV, history of knee joint trauma, and living in a rural location are identified as risk factors for KAM asymmetry. Conversely, increased knee-extension muscle strength and a per-capita monthly household income of 3000 ~ 6000 yuan serve as protective factors against this asymmetry.
