From the Guidelines

Total Hip Arthroplasty (THA) prosthetics can last for approximately 15-20 years, with a 90% survival probability at 10 years, and 65% at 20 years, as reported in a study published in the Annals of the Rheumatic Diseases 1. The longevity of THA prosthetics depends on several factors, including patient age, activity level, weight, surgical technique, and implant materials.

  • Patient age is a significant factor, with younger patients tend to have higher revision rates due to increased activity levels and longer life expectancy.
  • Implant materials, such as ceramic-on-polyethylene and metal-on-highly-cross-linked polyethylene bearings, have been shown to demonstrate better long-term outcomes with lower wear rates.
  • Regular follow-up appointments with orthopedic surgeons are crucial to monitor implant performance and address any potential issues promptly. Key factors that can influence the lifespan of THA prosthetics include:
  • Patient activity level and weight, with higher BMI and increased activity levels potentially leading to faster implant wear.
  • Surgical technique, with improved techniques and materials leading to better outcomes.
  • Implant design and materials, with newer implants potentially lasting longer than older models. According to the study, most failures of THA prosthetics occur within the first 7 years, and are often due to prosthesis loosening 1. However, with proper care and maintenance, including regular follow-up appointments and a healthy lifestyle, patients can maximize the lifespan of their THA prosthetics.

From the Research

Average Lifespan of Total Hip Arthroplasty (THA) Prosthetics

  • The average lifespan of THA prosthetics can vary depending on the type of bearing surface used, with ceramic-on-polyethylene and ceramic-on-ceramic being two common options 2, 3.
  • A study on ceramic-on-polyethylene bearing surfaces found that the probability of survival of the prostheses without revision was 95% at five years, 95% at ten years, 89% at fifteen years, and 79% at twenty years 2.
  • Another study on highly cross-linked polyethylene found that the use of HXLPE in THA for patients aged 50 years and younger has performed exceptionally well without evidence of significant wear causing mechanical loosening or necessitating revision, with a mean follow-up of 17.3 years 4.
  • A systematic review and meta-analysis on ceramic-on-ceramic total hip arthroplasty found that the 10-year survival rate was 96%, with a low rate of aseptic loosening and ceramic fracture 5.
  • A comparative study on ceramic-on-ceramic versus ceramic-on-polyethylene found that ceramic-on-polyethylene offered significantly better clinical outcomes at a minimum of 13 years follow-up 3.

Factors Affecting Lifespan

  • The type of bearing surface used can affect the lifespan of THA prosthetics, with ceramic-on-polyethylene and ceramic-on-ceramic having different wear rates and failure modes 2, 3.
  • Patient age and activity level can also impact the lifespan of THA prosthetics, with younger and more active patients potentially experiencing higher wear rates and failure rates 6, 4.
  • The design and material of the femoral head and acetabular component can also influence the lifespan of THA prosthetics, with newer designs and materials potentially offering improved durability and reduced wear rates 5.
