Knee Joint

2.5K
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...

Area of Science:

  • Orthopedic Surgery
  • Arthroplasty Research
  • Biomedical Engineering

Background:

  • Conversion total knee arthroplasty (TKA) encompasses diverse procedures, including those following ligamentous reconstruction, ORIF, HTO, and UKA.
  • Conversion TKA cases often present increased operative times and surgical complexity compared to primary TKA.
  • Existing literature shows conflicting results regarding implant survivorship and patient outcomes for conversion TKA versus primary TKA.

Purpose of the Study:

  • To elucidate the specific challenges associated with conversion total knee arthroplasty.
  • To provide insights that can inform clinical decision-making and patient management strategies for conversion TKA.

Main Methods:

  • Review and synthesis of existing literature on conversion TKA.
  • Comparative analysis of outcomes between conversion TKA and primary TKA.

Main Results:

  • Conversion TKA is associated with higher surgical complexity and potentially increased complication rates.
  • Evidence on implant survivorship and patient-reported outcomes is mixed, with some studies indicating poorer results for conversion TKA.

Conclusions:

  • A deeper understanding of conversion TKA complexities is crucial for optimizing patient care.
  • Improved knowledge can lead to better patient expectation management, intraoperative adaptations, and postoperative guidance.
