Impact of end-stage knee osteoarthritis on perceived physical function and quality of life: A descriptive study from Jordan

Physical functioning in patients with end-stage knee osteoarthritis: A cross-sectional study in Jordan using self-reported questionnaire and performance-based tests

BACKGROUND

Knee osteoarthritis (OA) is a debilitating condition that leads to functional limitations. Self-reported questionnaires and performance-based tests are tools commonly used for measuring physical function.

OBJECTIVES

(1) To evaluate the impact of end-stage knee OA on functional outcomes and examine the association between self-reported and performance-based measures of function in patients with end-stage knee osteoarthritis awaiting total knee arthroplasty (2) To explore the interrelationships among pain, strength, and overall physical function in this patient population.

METHODS

In this cross-sectional analysis, 33 patients with end-stage knee OA were recruited and completed the knee Outcome Survey-Activities of Daily Living Scale (KOS-ADLS) and executed performance-based tests including the Timed Up and Go, the 30-second chair stand test, and the Stair Climbing Test. Knee pain, and isometric hip and knee strength were evaluated.

RESULTS

Patients perceived deficits in their physical functionwith a score of 35/100 on the KOS-ADLS and demonstrated functional limitations in all performed tasks. KOS-ADLs was weakly associated with TUG and 30s-CST (r=-0.301, p= 0.047, and r= 0.39, p= 0.014. respectively). Knee pain was linked with the KOS-ADL score and GRS score (r=-0.406, p= 0.010; r=-0.343, p= 0.027; respectively), while the strength of the affected side was correlated with the performed (p=< 0.001) and reported function outcomes (p= 0.007).

CONCLUSION

Participants exhibit declines in both perceived and executed functional abilities. Self-reported and performance-based functional measures are weakly correlated within our study group, highlighting the importance of incorporating both measures in clinical practice for a comprehensive evaluation of physical function. Pain was linked to subjective aspect of physical function, while strength was connected to perceived and performed functional capacity. Implementing a tailored rehabilitation program targeting muscle weakness and pain holds the potential to mitigate functional decline in individuals awaiting total knee arthroplasty (TKA).

Exploring the relationship between depression and multimorbidity in Chinese middle-aged and older people based on propensity score matching

BACKGROUND

This study aimed to explore the relationship between depression and multimorbidity among middle-aged and older people in China.

METHODS

The cross-sectional study used the 2018 China Longitudinal Study of Health and Retirement and included a sample of 19,761 middle-aged and older adults aged 45 years and above. Propensity score matching was used to match samples of individuals with and without depression symptoms. The association between depression symptoms and multimorbidity and dose-response relationships were analyzed using logistic regression and restricted cubic spline (RCS) models for matched samples.

RESULTS

Logistic regression analysis showed that the prevalence of multimorbidity was 1.49 times higher among middle-aged and older adults in the depression symptom group compared to the non-depression group (95% CI:1.24, 1.80). The RCS curves for the relationship between depression and multimorbidity showed an overall increasing trend (P = 0.028). And prevalence of arthritis and digestive disease in the depressed and non-depressed groups is 3.6% and 3.9%, respectively.

LIMITATIONS

It was difficult to draw conclusions about causation since the study was cross-sectional, and CESD-10 scores do not represent the population study finally diagnosed with depression, the conclusions should be promoted with caution.

CONCLUSIONS

Middle-aged and older people with depressive symptoms are more likely to have multimorbidity than non-depressed individuals. Furthermore, the likelihood of multimorbidity increases with higher depression scores, and the binary combinations were similarly distributed. Therefore, attention should be paid to the management of mental health in the middle-aged and older adult population to alleviate and prevent any mental health issues they might face.
