Economic Burden of Periprosthetic Joint Infection Following Primary Total Knee Replacement in a Developing Country.

Background: Periprosthetic joint infection is one of the devastating complications after primary total knee arthroplasty, which increases the financial burden on patients and affects their quality of life as well. The financial burden of periprosthetic joint infection after joint replacement in developed countries is well known. There is a need to evaluate the economic burden in developing countries such as Pakistan.

Micro-organisms and risk factors associated with prosthetic joint infection following primary total knee replacement-our experience in Pakistan.

Purpose: To identify potential risk factors and micro-organisms associated with prosthetic joint infection following primary total knee replacement surgery.

Hypothesis Of Study: Our hypothesis is that body mass index (BMI), operative time, type of surgery, and order of surgery especially in bilateral simultaneous cases have a major impact on prosthetic joint infection (PJI).

Methodology: We identified 4269 patients who underwent for primary knee replacement surgery between 2008 and 2018.
