Summary

Total hip arthroplasty (THA) recommendations vary. Cementless THA is advised for young patients, hybrid for middle-aged, and cemented THA for the elderly, optimizing outcomes.

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering

Background:

  • Total hip arthroplasty (THA) techniques face divergent expert opinions.
  • The Charnley low-friction arthroplasty demonstrates significant long-term success.
  • Addressing specific challenges in THA is crucial for improving patient outcomes.

Purpose of the Study:

  • To review current trends and evidence in total hip arthroplasty.
  • To provide evidence-based recommendations for implant selection based on patient age.
  • To emphasize the importance of biological and biomechanical considerations in THA.

Main Methods:

  • Review of existing literature and clinical outcomes of cemented and cementless hip arthroplasty.
  • Analysis of biological and biomechanical factors influencing implant performance.
  • Consideration of technological advancements and cost-effectiveness in healthcare.

Main Results:

  • Cemented implants can achieve improved long-term performance with meticulous cement technique.
  • Cementless hip replacement remains a viable option, especially for younger patients.
  • Identifying design limitations drives innovation through scientific research.

Conclusions:

  • Recommend cementless THA for very young patients.
  • Recommend hybrid THA (cemented stem, cementless cup) for middle-aged patients.
  • Recommend fully cemented THA for elderly patients.
