In a retrospective study conducted by Streubel regarding mortality associated with periprosthetic fractures of the femur, it was reported that patients with periprosthetic femur fractures have a similar or higher mortality risk than hip fracture patients. This number is expected to increase as the procedure rate increases as well. Why is it important to discuss these complications? Firstly, the economic burden from revision TKA’s performed in the USA has risen to a tremendous $2.7 billion. Treatment of complications is a complex and resource-consuming task. Regarding this data, we can understand that due to a tremendous rise in the number of total knee arthroplasties (TKR/TKA), it is expected that the incidence of periprosthetic fractures around the knee will rise accordingly. ![]() Regarding the gender of those undergoing knee arthroplasty, women constituted 60% of patients and males made up 40% of those requiring the procedure. When looking at the distribution of those procedures among different age groups, 663,600 procedures were performed in patients aged 65–84, which accounts for 94.7% of the total procedures. The incidence of knee arthroplasty increased from 145 to 223 during that time period, with an annual rate of change of 4.9%. The rate of knee arthroplasty grew by more than 50% over this time when measured in a population of 100,000. In addition, knee arthroplasty was the second leading procedure with the greatest change in occurrence from 2003 to 2012. This was the single most frequent procedure completed during hospital stays among patients. In 2012, 700,100 total knee replacements were performed in the USA. ![]()
