Bones of the Lower Limb: Femur and Patella01:16

Bones of the Lower Limb: Femur and Patella

8.2K
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...

Muscles that Move the Leg01:23

Muscles that Move the Leg

6.9K
The movement of the legs is facilitated by numerous muscles located within the anterior, medial, and posterior compartments of the thigh.
Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

764
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Muscles of the Leg that Move the Foot and Toes

5.1K
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....

Knee Joint01:23

Knee Joint

3.4K
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:

  • Orthopedics
  • Sports Medicine
  • Biomechanics

Background:

  • Patellofemoral pain is a prevalent knee condition in runners.
  • Most cases are linked to some degree of patellar malalignment.
  • Understanding contributing factors is crucial for effective treatment.

Purpose of the Study:

  • To outline methods for assessing static and dynamic factors of patellar malalignment.
  • To identify key anatomical, soft tissue, and strength deficits.
  • To guide successful rehabilitation programs for runners with patellofemoral pain.

Main Methods:

  • Assessment of static patellar positioning.
  • Evaluation of dynamic lower extremity mechanics during running.
  • Identification of anatomical variations.
  • Analysis of soft tissue restrictions.
  • Strength testing of key muscle groups.

Main Results:

  • Altered patellar position is frequently associated with specific biomechanical deviations.
  • Anatomical variations can predispose individuals to malalignment.
  • Soft tissue tightness and muscle strength imbalances are common contributors.
  • A comprehensive assessment identifies multifactorial causes of patellar malalignment.

Conclusions:

  • Effective management of patellofemoral pain requires addressing both static and dynamic malalignment.
  • Correction of anatomical, soft tissue, and strength deficits is essential for successful rehabilitation.
  • A thorough evaluation is key to developing individualized treatment plans for runners.
