Periprosthetic Fractures
A fracture occurring around an existing implant, such as a hip or knee replacement, is called a periprosthetic fracture. These are complex injuries because both the broken bone and the implant must be assessed.
Complex trauma
The fracture and existing implant must be considered together.
How these fractures occur
Periprosthetic fractures commonly follow a fall or other injury, although weakened bone or a loose implant may also contribute. Symptoms can include sudden pain, swelling, deformity and inability to use or bear weight through the limb.
Management depends on the fracture pattern, implant stability, bone quality and the patient’s broader health.

02 / What to know
What the assessment needs to establish
Imaging is used to define the fracture and determine whether the existing implant remains securely fixed. The team also considers bone quality, previous operations, infection risk, general health and the patient’s mobility before the injury.
Earlier operation reports, implant details and X-rays are helpful when available, but urgent treatment should not be delayed while searching for records.
03 / What to know
Fixation or revision
If the implant is stable, the fracture may be repaired using plates, screws, cables, wires or an intramedullary nail. If the implant is loose, damaged or cannot be supported reliably, one or more components may need revision.
Some injuries require both fracture fixation and revision joint replacement. The plan is individualised to restore a stable construct and support healing.
Recovery and rehabilitation
Weight-bearing instructions and recovery vary substantially with the fracture and reconstruction. Patients may need a walking aid, physiotherapy and support with daily activities while the bone heals.
Follow-up imaging allows the team to monitor healing and implant position. It is important to follow wound, medication, movement and weight-bearing instructions supplied by the treating team.
05 / Important guidance
When to seek urgent help
A suspected fracture around a joint replacement requires urgent medical assessment. Call Triple Zero (000) after a major accident, for severe pain or deformity, an open wound, a cold or numb limb, or when the person cannot be moved safely.

Periprosthetic Fractures FAQs
Helpful starting points before your consultation. Advice and recovery plans are always tailored to the individual.
What is a periprosthetic fracture?
It is a break in the bone around an existing joint replacement or other orthopaedic implant. These injuries can affect the bone, the implant’s stability or both.
Does the existing implant always need to be replaced?
No. Some fractures can be stabilised while retaining a well-fixed implant. If the implant is loose or damaged, revision replacement may be required.
How is the surgical plan decided?
The fracture pattern, implant stability, available bone, previous operations, general health and mobility goals are assessed together. Additional imaging and prior operation records may be needed.
What should I bring to my appointment?
Please bring your referral, Medicare details, relevant X-rays or scans, a current medication list and any useful reports from previous treatment or surgery. Contact the practice before your visit if you are unsure what is required.
