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 seveity of falls. However, in patients with KAs, risk of hip fracture has not been studied extensively
