Average Longevity of Total Hip Arthroplasty Prosthetics
The average longevity of Total Hip Arthroplasty (THA) prosthetics is approximately 15 to 20 years, with a 90% survival probability at 10 years and 65% at 20 years 1.
- Factors influencing the longevity of THA prosthetics include patient age, weight, and activity level, as well as the type of prosthesis used.
- Prosthesis loosening is a common cause of failure, with most failures occurring within the first 7 years after surgery 1.
- To maximize the longevity of the prosthesis, patients should maintain a healthy lifestyle, including a normal weight and avoiding high-impact activities.
- Regular follow-up appointments with an orthopedic surgeon are crucial to monitor the prosthesis and address any potential issues promptly.
- Additionally, patients may be prescribed medications to prevent complications such as blood clots and infection, although specific dosing regimens may vary depending on individual patient needs and surgeon preference, as seen in studies such as 1.
From the Research
Average Longevity of Total Hip Arthroplasty (THA) Prosthetics
- The average longevity of THA prosthetics can vary depending on several factors, including patient age, implant type, and surgical technique 2, 3, 4, 5.
- A study published in 2024 found that the 10-year survival rate for THA prosthetics in patients under 30 was 85.2%, with a 20-year survival rate of 54.5% 2.
- Another study published in 2019 reported a mean 5- and 10-year survival rate of 98.7% and 94.6%, respectively, for THA prosthetics in patients under 55 3.
- A 2015 study found that the chance of survival at 15 years after THA was 57.6%, at 20 years it was 34.6%, and at 25 years it was 11.6% 4.
- A scoping review published in 2022 reported that survival rates for THA at 5 and 20 years were 90%-100% and 60.4%-77.7%, respectively, in patients 55 years or younger 5.
Factors Affecting Longevity
- Patient age is a significant factor affecting the longevity of THA prosthetics, with younger patients tend to have lower survival rates due to higher functional expectations and increased wear and tear on the implant 2, 3, 5.
- Implant type and surgical technique can also impact the longevity of THA prosthetics, with cementless implants and specialized surgical techniques showing promising results in certain patient populations 2, 6.
- The presence of underlying conditions, such as developmental dysplasia of the hip or avascular necrosis, can also affect the longevity of THA prosthetics, with higher reoperation rates and lower survival rates reported in these patient groups 2, 5.
