Summary

Yearly monitoring after total hip replacement (THR) is crucial. Reoperation for hip implants is indicated for symptomless patients with significant bone loss to prevent fractures and ensure successful revision surgery.

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering

Background:

  • Total hip replacement (THR) is a common procedure.
  • Reoperations for THR are complex and require careful planning.
  • Long-term outcomes of THR depend on managing complications like loosening and bone loss.

Purpose of the Study:

  • To describe experiences with 106 reoperations following 1968 total and 18 Wagner arthroplasties.
  • To establish guidelines for managing THR reoperations.
  • To evaluate the necessity and timing of revision surgery.

Main Methods:

  • Review of 106 reoperations in 88 patients between 1969 and 1991.
  • Analysis of radiological findings and clinical symptoms.
  • Consideration of patient age, acetabular, and femoral states in surgical planning.

Main Results:

  • Yearly radiological examinations are recommended post-THR.
  • Radiological signs alone in asymptomatic patients do not necessitate reoperation.
  • Significant bone loss with loosening in asymptomatic patients requires reoperation due to fracture risk and compromised reimplantation.

Conclusions:

  • Stable fixation is the primary goal in THR reoperations.
  • Cementless prostheses and bone grafting are suggested for patients under 60 with significant bone loss.
  • Reoperation for THR demands advanced surgical skills.
