Bones of the Lower Limb: Femur and Patella01:16

Bones of the Lower Limb: Femur and Patella

2.7K
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...

Knee Joint

2.1K
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:

  • Functional success in total knee arthroplasty (TKA) critically depends on proper patellar tracking.
  • Several interconnected factors influence patellar mechanics during TKA.

Purpose of the Study:

  • To identify key factors influencing patellar tracking in TKA.
  • To provide guidance on controlling these factors for optimal patellar tracking.

Main Methods:

  • Review of prosthetic design considerations (trochlea, patellar component, tibial implant).
  • Analysis of surgical technique variables (approach, bone cuts, implant rotation, patellar resurfacing).
  • Evaluation of surgical options for instability (MPFL reconstruction, tibial tubercle medialization).

Main Results:

  • Patellar tracking is influenced by prosthetic trochlear design, patellar component characteristics, and tibial implant selection.
  • Accurate femoral and tibial bone cuts, along with appropriate implant rotation, are vital for correct alignment and patellar height.
  • Surgical management of peripatellar structures and patellar resurfacing techniques also impact tracking.

Conclusions:

  • Optimizing patellar tracking in TKA necessitates a multifaceted approach, integrating prosthetic choice with precise surgical execution.
  • Attention to detail in component design, bone preparation, and soft-tissue management is essential for achieving excellent functional results.
  • Medial patellofemoral ligament reconstruction and anterior tibial tubercle medialization are options for persistent patellar instability.
