human knee joint is the big spliff in human body.1Knee joint is the common site for continuing hurting in older patients . Knee junction is the most vulgar joint to get injured during contact sports .
Knee Joint Movements-2
torso weightiness is carried through the knee junction . Knee joint movements are flexure ( crease ) and extension ( straightens ) . Flexion and extension occur between tibia and femur bone while genus Patella slides over the femur bone . Knee joint flexion and extension occurs every time a stair is take forward or backward . Patella off-white is locate prior or in front of the knee joint . Patella slides over femur bone while knee joint is dead set or extend . Patella protects the front of the joint and also prior dislocation of knee joint .
Cause of Chronic Knee Pain During Knee Joint Movement-
Articulating Cartilages-
Articulating cartilages covers the inner joint airfoil of last of femur , tibia , and genus Patella . Articular cartilages are surrounded by lubricant fluid within knee joint.3The cartilage and the viscous fluid within genu joint purpose as cushion absorber during knee joint movements . In addition smooth privileged Earth’s surface of the gristle also supports smooth bending of knee joint .
Knee Joint Cartilage Abnormalities Causing Chronic Knee Pain-
Knee Joint Menisci
The menisci are the cartilage located on internal ( medial ) and out ( sidelong ) side of knee articulation . Sports injury or sneak and fall do semilunar cartilage tear . Meniscus also supports role of shock absorption during knee joint activities .
Cause Of Chronic Knee Pain Secondary To Menisci Abnormalities-
Knee Joint and Bones
stifle juncture is shape by femur , tibia , fibula and patella .
Bones of Knee Joint-
Knee Joint - This Consist of Two Joints .
Chronic Knee Pain Caused By Abnormalities Of Knee Joint And Bones Of The Knee Joint-
Ligaments of The Knee Joint-
There are four ligaments . Injury of any of the four ligament causes joint instability and dangerous painful sensation with knee joint apparent motion .
Cruciate Ligaments – Located at the center of the joint , one on each side .
Collateral Ligaments- Located at the inner (medial) and outer (lateral) side of the knee joint.
Chronic Pain Caused By Abnormality or Disease Of Knee Joint Ligament-
Tendons of The Knee Joint-
A tendon is problematic electric cord of sinewy tissue paper situate at the end of muscles and link up muscle to bone . Tendinitis is triggered by redness of tendon , which result in spartan pain .
The Quadriceps Tendon
The Patellar Tendon
Chronic Pain Caused By Abnormality Or Disease Of Knee Joint Tendon
Muscles Associated With Knee Joint-
muscularity muscular contraction and loosening results in joint flection ( bend ) and extension ( straightening ) of the branch at stifle spliff . sinew condensation pull out the nonflexible sinew confiscate to the off-white resulting in either flexion or wing of the knee articulation . compression of musculus quadriceps femoris muscle causes extension of knee joint and muscular contraction of hamstring tendon causes flexion of human knee joint .
The Quadriceps Muscle Groups-
The Hamstring Muscle Group-
Chronic Knee Pain Caused By Abnormality or Disease of Knee Joint Muscles.
