Knee Joint01:23

Knee Joint

The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris group...

Ceramic-on-ceramic hip implants show significant improvement in pain and function, preventing bone loss. While some squeaking occurred, no major complications like infection or osteolysis were observed.

Area of Science:

  • Orthopedic Surgery
  • Biomaterials Science
  • Medical Engineering

Background:

  • Conventional polyethylene bearing surfaces in total hip arthroplasty are associated with osteolysis and bone loss.
  • Ceramic bearing surfaces offer a potential alternative to mitigate wear and improve implant longevity.

Purpose of the Study:

  • To evaluate the clinical outcomes and radiographic findings of ceramic-on-ceramic total hip arthroplasties.
  • To assess the efficacy of ceramic bearing surfaces in preventing osteolysis and improving patient function.

Main Methods:

  • Retrospective review of 103 ceramic-on-ceramic total hip arthroplasties in 97 patients.
  • Analysis of preoperative and postoperative Harris Hip Scores, pain scores, and functional scores.
  • Radiographic assessment for complications such as fractures, dislocations, infections, and osteolysis.

The Use of Mixed Reality in Custom-Made Revision Hip Arthroplasty: A First Case Report

Published on: August 4, 2022

Main Results:

  • Significant improvements in Harris Hip Score (49.5 to 87.2), pain score (13.7 to 40.6), and functional score (30 to 41) were observed (P < .05).
  • No fractures, dislocations, infections, or osteolysis were detected radiographically.
  • A 4.9% incidence of "squeaky" hips was reported, with continued good performance.

Conclusions:

  • Ceramic-on-ceramic total hip arthroplasty demonstrates favorable short-to-mid-term clinical outcomes and effectively prevents osteolysis.
  • The ceramic bearing surfaces appear safe and effective, though long-term efficacy requires further investigation.
  • Auditory phenomena like "squeaking" may occur but do not necessarily indicate poor implant performance.
