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...
Ankle Joint01:10

Ankle Joint

The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...
Muscles of the Leg that Move the Foot and Toes01:28

Muscles of the Leg that Move the Foot and Toes

The human leg comprises an intricate system of muscles that facilitate the movement of feet and toes. Within this system, the muscles are categorized into the anterior, lateral, and posterior compartments, each with a unique set of muscles carrying out specific functions.
Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles.

Area of Science:

  • Orthopedics
  • Biomechanics
  • Gait Analysis

Background:

  • Knee osteoarthritis (OA) is associated with altered foot posture, but causality remains unclear.
  • Investigating foot changes after knee realignment is crucial for understanding OA progression.

Purpose of the Study:

  • To determine if foot posture and function change after total knee replacement (TKR).
  • To assess the foot's adaptive response to knee realignment.

Main Methods:

  • Nineteen patients with medial compartment knee OA underwent testing before and 12 months after TKR.
  • Measured Foot Posture Index (FPI), Arch Index (AI), and 3D gait kinematics (tibia, rearfoot, forefoot).

Main Results:

  • No significant changes in static foot posture (FPI, AI) were observed post-TKR.
  • Gait analysis revealed increased tibial external rotation and tibial transverse plane motion.
  • Significant changes in rearfoot motion (frontal and transverse planes) occurred after TKR.

Conclusions:

  • Total knee replacement (TKR) does not affect static foot posture.
  • TKR leads to significant alterations in rearfoot kinematics during gait.
  • The foot demonstrates adaptability by compensating for proximal knee malalignment.
