Population ageing has renewed interest in the capability approach (CA) as a framework for understanding wellbeing in later life. Yet research applying the CA to ageing remains fragmented, and its empirical focus is still not well understood. This study examines how CA-based ageing research has developed and how it explains capability constraints and adaptive responses in later life. Using Web of Science Core Collection records from 2000 to 2025, we combine comparative bibliometric analysis with a focused qualitative interpretive synthesis. A general CA corpus (n = 3416) was first constructed and then refined to identify a CA-in-ageing subset (n = 142). The bibliometric results suggest that CA-in-ageing research is more problem-oriented than the broader CA literature, with health and care evaluation, as well as mobility and accessibility, emerging as particularly prominent thematic concentrations in the retrieved corpus. The qualitative synthesis of five appraised studies further shows how capability loss may be experienced in everyday life through shrinking life-space, disrupted social participation, and threats to dignity. It also identifies adaptive strategies through which older adults rebuild routines, negotiate selective support, and re-establish participation through enabling environments and services. Given the small qualitative corpus, its reliance on several COVID-19-related studies, and its Western empirical contexts, the findings should be read as an explanatory account of possible mechanisms rather than as a comprehensive representation of later-life capability loss across all ageing settings. By integrating bibliometric mapping with qualitative evidence, this study clarifies how the CA has been operationalised in ageing research and highlights the importance of environmental accessibility, service stability, and participation opportunities in sustaining wellbeing in later life.
