Knee Arthroplasty and Risk of Hip Fracture: A Population-Based, Case–Control Study

The majority of knee arthroplasties (KAs) are performed in patients with osteoarthritis (OA). Although bone mass may be increased in these patients, subjects with knee OA may have an increased risk of hip fracture, possibly due to an increased severity of falls. However, in patients with KAs, risk of hip fracture has not been studied extensively. Arief Lalmohamed, Frans Opdam, Nigel K. Arden, Daniel Prieto-Alhambra, Tjeerd van Staa, Hubertus G. M.
