Knee Joint01:23

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...
Bones of the Lower Limb: Femur and Patella01:16

Bones of the Lower Limb: Femur and Patella

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 neck...

Summary

This study found that mild knee deformities show minimal changes in foot loading after knee replacement surgery. Foot pressure distribution slightly decreased overall, particularly in the toes, after total knee arthroplasty.

Area of Science:

  • Orthopedic Surgery
  • Biomechanics
  • Podiatry

Background:

  • Foot deformity can influence knee joint loading.
  • Understanding foot loading is crucial for knee implant success.

Purpose of the Study:

  • To investigate the impact of mild knee deformity on foot loading before and after total knee arthroplasty (TKA).

Main Methods:

  • Static foot loading was recorded in 24 patients with mild knee deformity.
  • Measurements were taken preoperatively and 3 months postoperatively.
  • Foot pressure distribution was analyzed across 6 geographic sites.

Main Results:

  • Overall foot loading decreased by an average of 10% post-TKA.
  • The most significant changes in loading were observed in the hallux and lesser toe regions.
  • Foot pressure ratios in the metatarsal heads, heel, and midfoot were approximately 0.94 postoperatively.

Conclusions:

  • Total knee arthroplasty in patients with mild knee deformity results in minimal changes to geographic foot loading.
  • These findings suggest a limited biomechanical impact on foot loading post-TKA for this patient group.
