Proximal Tibia Stress Fracture Caused by Severe Arthrosis of the Knee With Varus Deformity

Abstract not available. Introduction provided instead.

Stress fractures, which can result from abnormal stress on normal bone, differ from insufficiency fractures, in which normal stress is applied to abnormal bone.
Stress fractures of the tibia are relatively common in young people involved in military and sports activities.^1,2 Stress fracture of the proximal tibia, however, is a rare entity in the elderly and has been reported in association with varus gonarthrosis,^3-11 valgus gonarthrosis,^4,5,12,13 pyrophosphate arthropathy,¹⁴ rheumatoid arthiritis,¹⁵ osteoporosis,¹ Paget disease,¹⁶ and knee deformities.^17,18
In this article, we present 3 cases of stress fractures of the tibia in association with severe varus gonarthrosis of the knee.
