Risk of Bone Fracture Around Implants After First-Time and Replacement Hip and Knee Surgery

Over a ten-year period, 52,136 primary total hip replacements and 44,511 primary total knee replacements were performed.

• The rate of peri-prosthetic fracture was 0.9% after primary total hip replacement and 0.6% after primary total knee replacement five years post-operatively.
• The fracture rate increased to 4.2% after revision total hip replacement and 1.7% after revision total knee replacement.
• Females, patients older than 70, and those undergoing revision surgeries experienced a higher likelihood of peri-prosthetic fractures.
• There is a suggestion that adjuvant medical treatment may help reduce peri-prosthetic osteoporosis in at-risk patients.
