These muscles work in groups to flex extend and stabilize the knee joint. The knee ligaments connect the thigh and shin bones femur tibia and work together to control how the knee moves to keep it stable and prevent injury.
Diagram of Knee Joint showing Meniscus.
Diagram of the knee cap. The kneecap slides along a groove in the femur as the knee bends. It is held in place by a ligament at the bottom and a tendon on top. Those connect to the femur and tibia.
Sometimes due to. The kneecap should track smoothly in the groove on the lower end of the thigh bone. If this does not happen the cartilage on the two surfaces may wear away and the bones come into contact with each other causing pain due to arthritis.
Twisting or trauma could cause the kneecap to move out of the groove in the thigh bone. This produces severe pain and swelling at the. The given diagram of the knee joint can help you to understand its various parts and the description given below will give you an insight of the functioning of the knee.
There are three bones in the knee namely the femur which is the thigh bone tibia which is the shin bone and patella which is the knee cap. Following are the function and names of knee parts which work together and make the locomotion possible for a human being. Knee actually consists of three bones femur tibia and patella.
Femur is the thigh bone tibia is the shin bone and patella is the small cap like structure which rests on the other two bones. Knee Diagram - Pro Knee Pain Relief. Our interactive 3D knee diagram is an informative 360 degree rotating model.
Each of the 6 sections Bones Connective Tissue 1 Connective Tissue 2 Deep Muscles Muscles Skin can be opened up rotated left or right and viewed more closely. Patella Knee Cap Your patella or knee cap is a circular-triangular bone approximately 2 inches across that is embedded between the quadriceps tendon above and patellar tendon below. Bones embedded in tendons are called sesamoid bones and they protect the tendons and improve the function of the joint by holding the tendons away from the center of the joint.
The knee joins the thigh bone femur to the shin bone tibia. The smaller bone that runs alongside the tibia fibula and the kneecap patella are the other bones that make the knee joint. This first knee pain diagnosis chart focuses on pain at the front of the knee.
Then next one further down looks at pain behind the knee. Pain Above the Knee Cap yellow Quadriceps Tendinopathy. Damage to the quadriceps tendon causing pain above the kneecap that is worse with activity.
Outer Knee Pain blue. The knee ligaments connect the thigh and shin bones femur tibia and work together to control how the knee moves to keep it stable and prevent injury. There are four different ligaments in the knee.
Found on the inner side of the knee. Patella Knee cap The patella kneecap is the largest sesamoid bone of the body. A sesamoid bone is a type of short bone.
The patella is found in the tendon of the quadriceps femoris muscle the large muscle of the thigh that passes across the knee to attach to the tibia. The patella joins with the patellar surface of the femur. The muscles that affect the knees movement run along the thigh and calf.
They are attached to the femur thighbone tibia shinbone and fibula calf. The knee joint is a synovial joint that connects three bones. The femur tibia and patella.
It is a complex hinge joint composed of two articulations. The tibiofemoral joint and patellofemoral joint. The tibiofemoral joint is an articulation between the tibia and the femur while the patellofemoral joint is an articulation between the patella and the femur.
Diagram of Knee Joint showing Meniscus. The meniscus is a crescent-shaped structure composed of cartilage that functions to distribute body weight evenly across the three bones that make up the knee joint. The thigh bone shin bone and knee cap.
The surfaces of these bones are covered with cartilage which allows the bones to move smoothly. The knee is the joint where the bones of the lower and upper legs meet. The largest joint in the body the knee moves like a hinge allowing you to sit squat walk or jump.

Pain on the inside of the knee cap. The assumed reason that the bent knee causes pain is that the articular cartilage the white covering on the ends of the bone can only get nutrients from the joint synovial fluid. The patella is the kneecap bone.
It lies within the quadriceps tendon. This large tendon from the powerful thigh muscles quadriceps wraps round the patella and is attached to the top of the lower leg bone tibia. The quadriceps muscles straighten the knee.
The back of the patella is covered with smooth cartilage. The prepatellar bursa is located in front of the knee cap. Pre means before in Latin and patella is the medical term for knee cap.
So this bursa comes before the knee cap. The muscles of the knee include the quadriceps hamstrings and the muscles of the calf. These muscles work in groups to flex extend and stabilize the knee joint.
These motions of the knee allow the body to perform such important movements as walking running kicking and jumping. Anatomy of knee pain - YouTube. Anatomy of knee pain.
