Yes, you should worry about a symptomatic urinary tract infection (UTI) after a Total Knee Arthroplasty (TKA).
If left untreated, bacteria from a UTI can travel through your bloodstream and settle into your new knee joint, leading to a serious complication known as a per prosthetic joint infection (PJI).
Why UTIs Matter After TKA:
The Bloodstream Connection: Bacteria causing a urinary tract infection (often E. coli) can enter your bloodstream. The area around your new joint is highly vascular, giving bacteria an opportunity to adhere to the metal or plastic components.
Timing is Critical: Research indicates that patients who develop a symptomatic UTI within the first few weeks after TKA face a higher risk of joint infection.
Asymptomatic Bacteria: If a urine test shows bacteria but you have no symptoms (burning, fever, urgency), it is often considered asymptomatic bacteriuria and may not require treatment, as it typically does not increase the risk to your joint.
Symptoms to Watch For:
If you notice any of the following urinary symptoms, contact your surgical team immediately:
-Burning or pain during urination
-Frequent or urgent need to urinate
-Blood in the urine
-Cloud or foul-smelling urine
-Unexplained chills, joint pain, or fever
