Joint proprioception in the elderly with and without hip fracture.

Objectives: Decreased proprioception may contribute to the risk of falls in elderly patients. The purpose of this study is to determine whether patients with hip fractures have decreased hip proprioception compared with aged-matched controls, and whether hip proprioception differs in patients with repaired fractures compared with patients who have undergone prosthetic hip replacement after hip fracture.

Design: Retrospective.

Changes in bone mineral density of the proximal femur after total knee arthroplasty.

This study investigates the relationship between total knee arthroplasty (TKA) and bone mineral density (BMD) in the same and opposite hips. The study prospectively evaluated 24 consecutive patients undergoing TKA (31 knees, 47 hips). The mean follow-up was 48 months.
