Due to the increase in life expectancy, the number of patients with knee osteoarthritis in the society is increasing as well. treatment options for the early-stage knee osteoarthritis include nonsteroidal anti-inflammatory drugs, intra-articular injections and physical therapy modalities. in patients with advanced stage of osteoarthritis and clinical complaints, by virtue of the advances in surgical experience and implant production, knee arthroplasty becomes more successful and durable. despite the innovations in implant technology and surgical treatment methods, complication rate increases due to hypertension (ht), osteoporosis (op) and diabetes mellitus (dm). in this paper, a 67-year-old female patient with femoral neck fracture that was identified 6 months after a total knee arthroplasty performed due to the knee osteoarthritis was discussed in the light of literature.
