Bones of the Lower Limb: Femur and Patella01:16

Bones of the Lower Limb: Femur and Patella

9.3K
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

3.7K
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...

Summary

Avoiding patellofemoral overstuffing in total knee arthroplasty (TKA) is crucial for success. Precise pre-operative planning and surgical technique are key to achieving an anatomic reconstruction and preventing complications like anterior knee pain.

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering
  • Knee Arthroplasty

Background:

  • Patellofemoral overstuffing is a significant complication in total knee arthroplasty (TKA), leading to a notable revision rate of approximately 15%.
  • Symptoms of overstuffing are variable, including limited flexion, patellofemoral maltracking, and anterior knee pain, highlighting the need for careful management.

Purpose of the Study:

  • To elucidate the diverse reasons contributing to patellofemoral overstuffing during TKA.
  • To present effective strategies for avoiding patellofemoral overstuffing in TKA procedures.

Main Methods:

  • Analysis of factors influencing patellofemoral overstuffing, focusing on femoral, patellar, and tibial components.
  • Emphasis on pre-operative planning, including lateral view X-ray analysis and implant positioning.

  • Detailed examination of femoral resection block positioning and patellar resection techniques.

    • Main Results:

    • Patellofemoral overstuffing often originates from the femoral side, but patellar and tibial factors also contribute.
    • Accurate positioning of femoral resection blocks and appropriate AP sizing are critical.
    • Correct patellar resection height and plane, along with avoiding lateral component placement, are essential for preventing overstuffing.

    Conclusions:

    • Anatomic reconstruction of the patellofemoral compartment is vital for successful TKA.
    • Meticulous pre-operative planning of femoral component size and position, coupled with precise surgical execution and adequate bone resection, effectively prevents patellofemoral overstuffing.
