VO₂ max is a key physiological marker of aerobic capacity that is associated with post-operative outcomes and long-term health.

While some studies hypothesise that this is due to reduced physical activity, direct measurement of activity levels or multivariate adjustment was generally lacking. Postoperatively, structured rehabilitation programmes may lead to improvements in VO₂ max, although findings vary based on the type, intensity, and duration of the intervention. Low-frequency or home-based exercise showed small improvements, while more intensive programmes, such as high-intensity interval training, had greater effects. However, many studies excluded patients with common comorbidities, limiting generalisability.</div></div><div><h3>Major conclusions</h3><div>Hip and knee replacement surgery may provide a critical window for improving cardiovascular fitness, especially when accompanied by targeted rehabilitation. These findings have important implications for nursing practice. Nurses can play a pivotal role in promoting structured aerobic exercise, supporting use of wearable technologies, and ensuring recovery pathways address cardiorespiratory health alongside joint mobility.
