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...

The PFC modular total knee system demonstrates good quality and patient satisfaction for osteoarthritis, rheumatoid arthritis, and posttraumatic osteoarthritis. This study evaluated 500 knee replacements, achieving excellent or good outcomes in most cases.

Area of Science:

  • Orthopedic Surgery
  • Biomaterials Science

Background:

  • Total knee replacement is a primary solution for severe osteoarthritis, rheumatoid arthritis, and posttraumatic osteoarthritis.
  • Patient pathological changes and deformities necessitate individualized treatment approaches for knee joints.

Purpose of the Study:

  • To evaluate the long-term outcomes and survivorship of the PFC modular total knee system.
  • To assess the efficacy of the PFC system in addressing diverse patient conditions and deformities.

Main Methods:

  • Prospective study of 500 cemented primary PFC modular total knee replacements implanted between 1991 and 2001.
  • 350 prostheses in 295 patients with osteoarthritis, rheumatoid arthritis, or posttraumatic osteoarthritis were analyzed.
  • Survivorship analysis was based on revision surgery due to aseptic loosening, with patient age averaging 68.3 years.

Main Results:

  • Excellent or good outcomes were reported in 333 out of 350 knees (95.1%) according to the Knee Society Clinical Rating System.
  • Aseptic loosening was the primary concern for revision surgery, influencing survivorship.
  • Complications included two cases of posterior tibial component dislocation and one instance of septic loosening requiring revision.

Conclusions:

  • The PFC total knee system is a high-quality prosthesis suitable for various primary and revision knee replacement scenarios.
  • The system facilitates effective solutions for complex cases, leading to favorable patient outcomes and high satisfaction.
  • Individualized treatment remains crucial, but the PFC system offers versatility in addressing diverse joint pathologies.
