A periprosthetic fracture usually needs surgery when the broken bone is displaced or unstable, or when the implant has become loose. Small, stable cracks around a well-fixed implant may sometimes heal with protected weight-bearing and close monitoring. A periprosthetic fracture is a break in the bone around an artificial joint, most often after a hip replacement or knee replacement. This guide explains the causes, warning signs, and tests involved. It also covers how specialists decide between conservative care and periprosthetic fracture surgery, plus surgical options, recovery, and prevention tips.
What Is a Periprosthetic Fracture?
A periprosthetic fracture is a break in the bone surrounding an artificial joint. It most often affects the thigh bone near a hip or knee implant.
These fractures can happen during the original operation or many years later. Common locations include:
Because an implant is involved, treatment is more complex than for a routine broken bone.
- Femur around a hip stem
- Lower femur above a knee implant
- Upper tibia below a knee implant
- Kneecap after knee replacement
- Upper arm near a shoulder implant
Common Causes and Risk Factors
Most periprosthetic fractures happen after a simple fall from standing height. Weak bone around the implant breaks more easily than healthy bone.
Factors that raise the risk include:
Knowing your risk factors helps you and your doctor plan safer daily activity.
- Osteoporosis or thinning bones
- Older age and frailty
- Loose or worn implants
- Previous revision joint surgery
- Rheumatoid arthritis or steroid use
- Balance problems and frequent falls
Symptoms That Need Urgent Attention
A fracture around an implant usually causes sudden pain after a fall or twist. Some people notice symptoms gradually if the bone was already weakened.
Warning signs may include:
If you have a joint replacement and notice these signs, seek medical care promptly.
- Severe pain near the replaced joint
- Inability to stand or bear weight
- Swelling and bruising
- Visible deformity or leg shortening
- A new clicking or unstable feeling

How Doctors Diagnose the Fracture
Diagnosis starts with a physical examination and a review of your joint replacement history. Imaging then shows the fracture pattern and the condition of the implant.
Tests may include:
For hip fractures, surgeons often use the Vancouver classification to guide the treatment plan.
- X-rays from several angles
- CT scan for complex fractures
- Comparison with earlier X-rays
- Blood tests to rule out infection
- Joint fluid testing if infection suspected
When Does a Periprosthetic Fracture Need Surgery?
Most periprosthetic fractures need surgery to restore stability and allow early movement. The decision depends mainly on fracture position, implant stability, and bone quality.
Surgery is usually advised when:
A loose implant often means revision knee replacement surgery or a hip revision is required, not just fixing the bone.
- The fracture is displaced or unstable
- The implant has become loose
- Bone stock around the implant is poor
- Walking or standing is impossible
- The fracture fails to heal with rest
When Non-Surgical Treatment May Work
Some fractures can heal without an operation. This is only suitable when the implant remains firmly fixed and the bone stays well aligned.
Non-surgical treatment for periprosthetic fracture may suit:
These patients need regular X-rays to confirm healing, since some fractures shift and later need surgery.
- Small, undisplaced cracks
- Some greater trochanter fractures
- Stable fractures with a fixed implant
- Patients too unwell for anaesthesia
Surgical Treatment Options at Lux Hospitals
The right periprosthetic fracture surgery depends on whether the implant is stable or loose. Surgeons tailor the procedure to the fracture site and your bone quality.
Common approaches include:
Your surgeon will explain which option best balances stability, healing, and recovery time.
- Open reduction and internal fixation with locking plates
- Intramedullary nailing for some knee fractures
- Revision hip replacement surgery for loose stems
- Bone grafting for poor bone stock
- Distal femur replacement in severe cases
Book a consultation at Lux Hospitals to discuss the right surgical option for you.
Recovery After Periprosthetic Fracture Surgery
Periprosthetic fracture recovery often takes several months. Healing time varies with age, bone health, and the type of surgery performed.
Recovery usually involves:
Following your rehabilitation plan closely gives the best chance of returning to independent walking.
- Early mobilisation with a walker
- Protected or partial weight-bearing
- Structured physiotherapy sessions
- Pain and blood clot prevention
- Regular follow-up X-rays
Possible Risks and Complications
Like any major operation, periprosthetic fracture surgery carries some risks. These are often higher because patients tend to be older and the bone is weaker.
Potential complications include:
Careful planning and experienced surgical teams help lower these risks.
- Infection around the implant
- Delayed healing or non-union
- Implant loosening or dislocation
- Blood clots in the legs
- Need for further surgery
Prevention Tips After Joint Replacement
Not every fracture can be prevented, but simple steps lower your risk. Protecting bone strength and preventing falls are the two main goals.
Helpful habits include:
Regular check-ups also catch early implant loosening before it leads to a fracture.
- Managing osteoporosis with your doctor
- Removing trip hazards at home
- Using grab bars and night lights
- Staying active with balance exercises
- Eating calcium and vitamin D-rich foods
- Attending routine implant follow-ups

Conclusion
A periprosthetic fracture is a serious injury, but effective treatment is available. Surgery is usually needed when the fracture is displaced, the implant is loose, or bone quality is poor. Small, stable fractures around a well-fixed implant may heal with careful non-surgical care and close monitoring.
The right choice depends on a thorough specialist assessment, including imaging and a review of your implant. If you have a joint replacement and develop sudden pain, swelling, or difficulty walking, seek prompt orthopaedic evaluation. The experienced team at Lux Hospitals can assess your fracture, explain every option clearly, and guide you through surgery and rehabilitation so you can regain mobility and confidence.
