Possible causes of ongoing or new pain
Timing, location, and triggers help narrow the possibilities. Pain that never improved after surgery creates a different question from new pain after years of good function. Symptoms during the first weeks of normal healing also require a different interpretation from late deterioration.
- Infection, which may occur early or years later
- Implant loosening, wear, bone loss, or fracture
- Instability, malalignment, stiffness, or soft-tissue irritation
- Tendon or muscle problems around the joint
- Pain referred from the spine or another joint
Warning signs that deserve prompt attention
Contact the surgical team promptly for new wound drainage, rapidly worsening redness or swelling, fever with increasing joint symptoms, or a sudden decline in function. A fall followed by deformity, severe pain, or inability to bear weight may require urgent evaluation.
These signs do not establish a diagnosis by themselves, but delaying assessment can make certain problems harder to treat. If symptoms feel emergent, seek emergency care rather than waiting for an office response.
What a revision evaluation may include
The evaluation starts with the original diagnosis, operation, implant information, recovery course, and symptom timeline. Examination looks at the joint, gait, motion, stability, strength, surrounding tissues, spine, and other possible pain sources.
Standing X-rays are central. Blood tests such as inflammatory markers and joint aspiration may be used when infection is a concern. CT, ultrasound, nuclear medicine studies, or other advanced imaging are selected only when they answer a specific question.
Why diagnosis comes before revision
Revision can be effective when it corrects a defined problem such as infection, loosening, instability, fracture, or implant failure. Results are less predictable when surgery is performed for unexplained pain without a correctable cause.
Treatment may involve observation, therapy, medication, treatment of a non-joint pain source, a limited component procedure, or full revision. The risks, recovery, and expected improvement depend on the failure mechanism and the reconstruction required.
