The knee joint has three parts. The thigh bone (the femur) meets the large shin bone (the tibia) to form the main knee joint. This joint has an inner (medial) and an outer (lateral) compartment. The kneecap (the patella) joins the femur to form a third joint, called the patellofemoral joint. The patella protects the front of the knee joint. Other than that tendon, ligament and muscles plays a vital role in functioning of knee joint.

Articular cartilage coats the ends of the bones in the knee joint to provide a smooth gliding surface so the bones in the joint move fluidly against each other and the “The crescent-shaped pad of cartilage called the meniscus functions as a joint stabilizer and provides a cushion between the weight-bearing bone surfaces in the knee.

Knee Anatomy

4 Major Reasons of Knee Pain

Week Knee / Leg Muscles

After the age of 40 years it is found in diferent research work that every 10 years there is around 8 to 10 % muscle loss. Due to week muscles the body weight get directly transferred to the knee bones which becomes the reason of knee pain. Symptoms often include pain, swelling, and di􀇗culty in walking.

Tendon/ Ligament Injury or sprain

Inflammation of the tendons/ ligament may result from overuse or due to injury in them that can be treated by Orthopaedic surgeon or by physiotherapist.

Torn or damaged Cartilage

Cartilage damage is the reason of knee pain in more than 80% case which enhances with the age and ignorance of same may leads to complicated surgeries in near future. If it is not ignored and treated in time, not only the progression disease can be stopped even it can be reversed.

Deformities in Knee Joint / Legs

Leg deformities are musculoskeletal abnormalities that can be congenital (something you are born with), developmental, or acquired as the result of fracture, infection, arthritis or tumor. Becomes the reason of joint pain due to early to damage of cartilage.
