|August 13, 1999
Summary
Chronic knee pain, often linked to osteoarthritis, may be better understood as a regional pain syndrome. Further research into its biological mechanisms and potential treatments like glucosamine is warranted.
Area of Science:
- Orthopedics
- Rheumatology
- Pain Medicine
Background:
- Chronic knee pain significantly impacts individuals, especially the elderly.
- Current diagnostic correlations between pathology and pain severity in osteoarthritis and chondromalacia patellae are poor.
- Psychometric factors better predict the impact of knee osteoarthritis, suggesting regional pain syndrome characteristics.
Purpose of the Study:
- To explore the underlying biological mechanisms of chronic knee pain.
- To investigate the relationship between psychometric variables and knee osteoarthritis impact.
- To review established and emerging factors in knee osteoarthritis prevention and treatment.
Main Methods:
- Review of literature on chronic knee pain, osteoarthritis, and chondromalacia patellae.
- Analysis of studies utilizing magnetic resonance imaging (MRI).
- Examination of research on muscle function, reflex quadriceps inhibition, and proprioception in knee osteoarthritis.
Main Results:
- Pathological findings show weak correlation with pain severity in knee conditions.
- Psychometric variables demonstrate a stronger correlation with the impact of knee osteoarthritis.
- Established risk factors include weight, injury, and occupational activity; potential roles for hormones and vitamins are emerging.
Conclusions:
- Chronic knee pain, particularly osteoarthritis, may function as a regional pain syndrome.
- Understanding biological mechanisms requires further investigation using advanced imaging and functional studies.
- Nutraceuticals like glucosamine warrant further research for osteoarthritis treatment.

01:16Bones 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...
01:10Bones of the Lower Limb: Tibia and Fibula
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...
01:23Knee 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...

01:10Ankle 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...
01:23Muscles that Move the Leg
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 to...

01:20Arteries of Lower Limbs
The external iliac artery transitions out of the body cavity, entering the femoral region of the lower leg, and is renamed the femoral artery at the point where it traverses the body wall. This artery is responsible for the distribution of blood to the thigh's deep muscles and the skin's ventral and lateral regions, achieved through several minor branches and the lateral deep femoral artery, which also spawns a lateral circumflex artery. The knee area receives blood from the genicular artery,...
