Preoperative low scores of Life Satisfaction Rating predicts poor outcomes after total knee arthroplasty: a prospective observational study

Background

Despite the continued improvement in the surgical techniques during primary total knee arthroplasty (TKA), literatures indicate that up to 10 to 20% patients are not satisfied with their outcomes. Psychological factors in this dissatisfaction are yet to be clearly identified. The aim of this study is to develop a method to assess whether the patient’s current mental state is suitable enough to accept a TKA surgery.

Methods

Preoperative demographic and clinical data of 532 patients who underwent TKA were prospectively obtained from January 2012 until December 2016. We recorded the scores evaluated by SF-36 questionnaire and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) preoperatively and 1 year postoperatively. Preoperative Life Satisfaction Rating (LSR) is emphatically evaluated.

Results

Poor preoperative score of LSR was a significant predictor of dissatisfaction after TKA. Patients with low LSR reported significant pain and stiffness, although there was no remarkable effect on functionality of the replaced joint. The results also showed that age and BMI were not strong predictors of satisfaction in TKA.

Conclusion

Our outcomes can help clinicians evaluate whether a patient’s current mental status is favorable for TKA. If patients have extreme low scores of LSR (less than 10), a psychological intervention should be recommended for better satisfaction following a TKA surgery. This would also allow surgeons to individually assess the risks and benefits of surgery.

Is giving or receiving psychologically beneficial to older mothers in South Korea? Importance of marital status

In order to understand intergenerational financial transfers and subjective well-being for older mothers, this study argues that marital status is an important factor to be considered. Using the first wave of the Korean Longitudinal Study of Aging (KLoSA), this study finds that married older mothers report higher levels of life satisfaction when they provide economic support but widowed older mothers feel higher levels of life satisfaction when they receive economic support. Also, regular or irregular financial support appears to also matter in the associations between financial support and life satisfaction. These findings suggest that married and widowed older mothers have different viewpoints about the parent-children relationship.

The role of the Australasian Journal on Ageing in the Asia-Oceania region

The role of the Australasian Journal on Ageing (AJA) in the Asia-Oceania region has been developing over the 30 years of the journal's publication, and review of its current and potential future roles is timely in the context of a number of developments in the region. This review describes the regional reach of the AJA, presents an analysis of regional content published over the 5 years to 2012, discusses the regional context with reference to other journals published in the region, and proposes several strategies for advancing the AJA's regional role. Pursuing these strategies would realise the AJA's potential as a vehicle for promoting the exchange of multidisciplinary knowledge on ageing.
