Greater Q-Angle Measures Are Not Associated With Pain and Muscular or Functional Performance in Elderly Women With Knee Osteoarthritis

Introduction Knees osteoarthritis (OA) is a complex degenerative disease with intra-articular changes affecting the amplitude of the quadriceps angle (Q). To measure this variable, it is necessary to use reliable protocols aiming at methodological reproducibility. The objective was to evaluate the intra-examiner and inter-examiner reliability of clinical and radiographic measures of the Q angle and to investigate the relationship between the degree of OA and the magnitude of this angle in the elderly. Materials and methods 23 volunteers had the Q angle measured by two evaluators at 48-h interval. Clinical measurements were collected by using the universal goniometer in the same position adopted in the radiographic examination. Results The intra-examiner reliability was good (0.722 to 0.763) for radiographic measurements and low (0.518 to 0.574) for clinical assessment, while inter-examiner reliability was moderate (0.634) for radiographic measurements and low (0.499) to the clinics. The correlation analysis between the radiographic values with the OA classification showed no correlation between them (p = 0.824 and r = -0.024). Conclusion Clinically, it is suggested that the radiographic examination is preferable to evaluate the Q angle of elderly women with knee osteoarthritis. Moreover, the magnitude of this angle did not correlate with the degree of impairment of OA in this population.

Abstract Introduction: Knee osteoarthritis is a degenerative and inflammatory disease that causes skeletal muscle dysfunction and induces limitation of functional activities, such as gait. Objective: To assess the relationship between gait speed and functional performance in elderly women with knee osteoarthritis. Methods: 38 elderly women were divided into two groups: knee osteoarthritis group (KOAG) (n = 24, 68 ± 4.42) and control group (CG) (n = 14, 66.35 ± 3.54). Gait speed data was assessed through Qualisys system and functional performance through a checklist of the International Classification of Functioning, Disability and Health (ICF). Results: Comparing with CG (p < 0.05), KOAG patients had lower gait speed (p = 0.004) and worse functional performance in d4500 (walking short distances), d4501 (walking long distances), d4502 (walking on different surfaces), and d4503 (walking around obstacles) ICF categories. By associating gait speed and functional performance in KOAG, significant differences were found in the d4500 (p = 0.019) and d4501 (p = 0.035) categories, but none for either the d4502 (p = 0.511) or d4503 (p = 0.076) categories. Gait speed was negatively correlated with d4500 (rho = -0.585, p = 0.003), d4501 (rho= -0.552, p = 0.005), and d4502 (rho = -0,548, p = 0,006). Conclusion: Gait speed is related to functional performance in elderly women with knee osteoarthritis for the activities of walking short distances, walking long distances, and walking on different surfaces. However, it seems that gait speed is not related to walking around obstacles.

Knee osteoarthritis (OA) leads to the damage of all joint components, with consequent proprioceptive impairment leading to a decline in balance and an increase in the risk of falls. This study was aimed at assessing postural stability and proprioception in patients with knee OA, and the relation between the impairment in postural stability and proprioception with the severity of OA and functional performance. Thirty-eight patients with knee OA were recruited. OA severity was classified with the Kellgren–Lawrence score. Postural stability and proprioception were assessed in double- and single-limb stance, in open- and closed-eyes with an instrumented device. Functional performance was assessed using the Knee Score Society (KSS) and the Short Performance Physical Battery (SPPB). Relationships between variables were analyzed. Postural stability was reduced with respect to reference values in double-limb stance tests in all knee OA patients, while in single-stance only in females. Radiological OA severity, KSS-Functional score and SPPB were correlated with greater postural stability impairments in single-stance. Knee OA patients show decreased functional abilities and postural stability impairments. Proprioception seems to be impaired mostly in females. In conclusion, clinical management of patients with OA should include an ongoing assessment and training of proprioception and postural stability during rehabilitation.
