From the Guidelines

Total hip arthroplasty prosthetics have a high survival probability, with 90% lasting at least 10 years and 65% lasting at least 20 years. The longevity of these prosthetics is influenced by various factors including patient age, activity level, and overall health, as well as the materials used in the implant 1.

Key Factors Influencing Longevity

  • Patient age: Younger patients tend to have a higher rate of implant wear due to increased activity levels 1.
  • Activity level: More active patients may experience faster wear of their implants, potentially requiring revision surgery sooner.
  • Implant materials: Ceramic-on-ceramic or highly cross-linked polyethylene implants tend to have better wear resistance compared to traditional metal-on-metal designs.

Survival Probability

The study found that joint revisions also performed well, with a 20-year survival of 61% 1. Most failures occurred within the first 7 years and were most often due to prosthesis loosening.

Clinical Implications

The high survival probability of total hip arthroplasty prosthetics suggests that these implants can provide long-term relief from pain and improvement in functional ability for patients with conditions such as ankylosing spondylitis 1. However, individual results can vary, and some patients may require earlier revision due to complications or wear.

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 underlying condition 2, 3, 4, 5, 6.
  • A study published in 2024 found that the 10-year survival rate for THA prosthetics in patients under 30 was 85.2%, with 69.8% survival at 15 years and 54.5% at 20 years 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 years old 3.
  • A 2022 study found that the estimated survivorship at 34 years postoperatively was 90.9% for cup revision for aseptic loosening, 80.5% for stem revision for aseptic loosening, and 22.1% for any revision in patients under 50 years old 4.
  • A 2015 study reported that the chance of survival at 15 years was 57.6%, at 20 years it was 34.6%, and at 25 years it was 11.6% for patients undergoing THA 5.
  • A 2022 scoping review found 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 6.

Factors Affecting Longevity

  • Patient age: Younger patients tend to have lower survival rates and higher reoperation rates compared to older patients 2, 3, 4, 5, 6.
  • Implant type: Different implant types and materials can affect the longevity of THA prosthetics 3, 4.
  • Underlying condition: Patients with hip dysplasia and avascular necrosis tend to have higher reoperation rates and lower survival rates compared to those with other primary diagnoses 3, 6.
