Stress fractures of the tibia are relatively common in military and young people. However, stress fracture of the proximal tibia is rare in elderly patients, but has been reported in association with osteoporosis, Paget disease, rheumatoid arthritis, pyrophosphate arthropathy, and knee deformities. We experienced a 65-year-old patient who did not have a chronic disease, with a stress fracture with primary degenerative knee osteoarthritis with varus deformity, which occurred at the proximal tibia, and we report on this unusual case with a literature review.

Orthoradiogram shows varus knee alignment with degenerative medial compartmental osteoarthritis of the knee joints at left (arrow). On initial radiographs, knee anteroposterior (A; arrow) and knee lateral (B; arrow), tibial stress fracture was apparent. An intracortical fracture was observed at the medial aspect of the proximal tibia with callus formation, suggesting a stress fracture at left. On bone scan (A) and (B), intense focal radioactive uptake in the left proximal tibial shaft, suggesting a fracture. Focally increased radioactive uptake in the medial compartment of the left knee suggests osteoarthritis. Knee anteroposterior (A) and knee lateral (B) show that total knee arthroplasty with a long tibial stem bridging the fracture site was performed. Radiographs obtained 6 months later show a nearly healed tibial stress fracture. After left knee replacement the alignment is reasonable.
