Knee Joint

3.0K
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
  • Biomedical Engineering

Background:

  • Lateral unicompartmental knee arthroplasty (LUKA) demonstrates excellent functional results and implant survival in appropriately selected patients.
  • Current research primarily focuses on medial unicompartmental knee arthroplasty (MUKA), necessitating more high-quality studies for LUKA indications.
  • Technical challenges and unfamiliarity with LUKA can be mitigated by operative adjuncts like robotics and navigation.

Purpose of the Study:

  • To evaluate the current status and future directions for lateral unicompartmental knee arthroplasty.
  • To identify areas requiring further research to expand indications and improve outcomes for LUKA.
  • To compare LUKA and MUKA, highlighting their distinct procedural nuances.

Main Methods:

  • Review of existing literature on lateral unicompartmental knee arthroplasty.
  • Analysis of the impact of operative adjuncts and implant designs on LUKA.
  • Discussion of potential complications, such as mobile-bearing dislocation.

Main Results:

  • LUKA offers excellent functional outcomes and implant survivorship for suitable candidates.
  • Operative adjuncts show potential to reduce the technical difficulty of LUKA.
  • Limited availability of lateral-specific implants and concerns regarding mobile-bearing device failures require attention.

Conclusions:

  • High-quality studies are essential to confirm expanded indications for LUKA.
  • Advancements in lateral-specific implants and further evaluation of bearing designs are needed.
  • Future research should differentiate between MUKA and LUKA in registry and cohort studies for clearer understanding.
