Red Flags

Red Flags After Joint Replacement

Warning signs after hip or knee replacement, including infection concerns, blood clot symptoms, wound drainage, fever, chest symptoms, falls, and sudden pain.

Schedule a Consultation
Best Practical Answer

After joint replacement, patients should contact the care team urgently for fever, spreading redness, wound drainage, sudden severe pain, a fall, inability to bear weight, calf pain or major swelling, chest pain, shortness of breath, fainting, or other symptoms the discharge instructions identify as urgent.

Original TJS Patient Journey Table

Milestones to track and discuss

This table is an original TJS patient education tool. Use it to organize questions for red flags after joint replacement; your surgeon's instructions should always control.

Journey stageWhat to trackWhat a good plan clarifies
Before surgeryConfirm diagnosis, medications, home setup, support person, transportationPatient can explain the plan and knows who to call
Surgery dayArrival time, anesthesia plan, mobility check, discharge criteriaDischarge is based on safety, not the clock
First 2 weeksWalking quality, swelling, pain control, wound status, therapy instructionsRecovery is trending forward without warning signs
Weeks 3 to 6Driving/work questions, gait, stairs, range of motion, enduranceActivity increases without major next-day setbacks
Safety decision path:
  1. Is the symptom expected for this stage, or is it worsening?
  2. Does it affect walking, breathing, wound safety, pain control, or the ability to follow instructions?
  3. Use the discharge instructions to decide: continue the plan, call the care team, or seek urgent care.

Wound and infection concerns

Redness that spreads, drainage, fever, chills, increasing warmth, worsening pain, or a wound that opens should be reported promptly. Do not try to manage a possible infection alone.

Blood clot and chest symptoms

New calf pain, major one-sided swelling, chest pain, shortness of breath, coughing blood, or fainting can be urgent. Patients should follow discharge instructions and seek emergency care when directed.

Mechanical concerns

A fall, sudden pop, inability to bear weight, new deformity, dislocation concern, or sudden loss of function should be reviewed quickly.

When in doubt

Discharge instructions should list phone numbers and escalation steps. If symptoms feel severe or life-threatening, emergency care is appropriate.

How to Use This Page

Bring it into the conversation.

This guide is meant to make the appointment more useful. Patients can use it to write down questions, compare their current symptoms with the usual decision points, and identify what they do not yet understand. The most useful version of the conversation is specific: what joint hurts, what activities are limited, what has already been tried, what support exists at home, and what outcome would actually feel meaningful.

What TJS Should Confirm

Individual details still decide the plan.

Total Joint Specialists should confirm the diagnosis, procedure fit, medical risk, location, surgery-center plan, discharge instructions, therapy plan, and follow-up schedule for the individual patient. Online guidance can explain the pathway, but it cannot clear someone for surgery, guarantee same-day discharge, diagnose a complication, or replace instructions from the surgeon, anesthesia team, physical therapist, or discharge nurse.

Practical Checklist

Details to clarify before relying on a plan

Write these down before the visit or before discharge, because the safest instructions are the ones the patient and support person can repeat back clearly.

  • Which hip or knee problem is being treated, and what evidence supports that diagnosis?
  • Which procedure or nonsurgical option is being considered, and what alternatives remain reasonable?
  • Which office, surgery center, surgeon, anesthesia plan, and follow-up pathway apply to this patient?
  • Which symptoms should trigger a call, an urgent visit, or emergency care after surgery?
  • Which medication, therapy, wound care, driving, work, and activity instructions override general online education?
Common Questions

Patient journey FAQ

Is some swelling normal?

Yes, swelling is common, but sudden major swelling, calf pain, chest symptoms, or worsening asymmetry should be reported.

Is drainage ever normal?

Small early spotting may happen, but active drainage, increasing drainage, odor, fever, or redness should be reported.

Should I wait until my follow-up?

Do not wait for a routine follow-up if symptoms match urgent warning signs or are rapidly worsening.
