Abstract:
BACKGROUND:Periprosthetic femoral fracture after total knee arthroplasty is related with the osteoporosis, bone defects, prosthesis, frail patients and high complication rate, so it is difficult to prevent and treat.
OBJECTIVE:To explore the risk factor, classification, treatment, rehabilitation and prophylaxis of periprosthetic femoral fracture after total knee arthroplasty based on the reviewed and summarized articles published in recent years.
METHODS:A computer-based online search was conducted in PubMed database from January 1, 1990 to December 31, 2011 and in SpringerLink database from 1980 to 2011 for the related articles with the key words of“periprosthetic fracture, knee”in English. A total of 626 articles were retrieved.
RESULTS AND CONCLUSION:According to inclusion and exclusion criteria, the articles were screened and 40 articles were included final y. The results showed that with the extensive development of total knee arthroplasty, the incidence of periprosthetic femoral fracture was increased gradual y;due to the poor prognosis, we should pay attention to the prevention. The risk factors of periprosthetic femoral fracture included patients’ internal factor that was hard to control, and some external factors such as the surgical techniques. Rorabeck classification was commonly applied for periprosthetic femoral fracture after total knee arthroplasty, but it was not perfect in clinical application. Kim classification wil be better for clinical guidance. The treatment of periprosthetic femoral fracture included nonoperative treatment, open reduction and internal fixation, retrograde intramedul ary nailing and revision arthroplasty. An appropriate treatment is chosen depending on fracture classification, local bone quality, patients’ medical and nutritional status. At present, however, there is not a perfect guideline for the selection of appropriate treatment method. But the early functional exercise is beneficial to prevent the related complications caused by longtime immobilization and the loss of joint function. Therefore, the indications must be under strict control in the treatment of periprosthetic femoral fracture after total knee arthroplasty. Except the firm fixation, early exercise for the patients should be encouraged at the same time.
