Proximal tibial stress fractures associated with primary degenerative knee osteoarthritis

Abstract

Tibial stress fractures are not rare--they have been extensively studied in young athletes and soldiers and in elderly people with rheumatoid arthritis, osteoporosis, Paget's disease, pyrophosphate arthropathy, and hyperparathyroidism--but they seldom occur in patients with severe primary degenerative knee osteoarthritis. The etiology, diagnosis, and optimal treatment of these fractures remain a challenge. In this article, we review the English-language literature on the symptoms, diagnosis, treatment options, and final outcomes of these fractures, and we report 2 new cases of proximal tibial stress fractures in elderly women with severe primary degenerative knee osteoarthritis.
