Mar 21;(2) The relationship between the rotation possibilities between femur and tibia and the lengths of the cruciate ligaments. The Relationship Between Tibia-Femur Length Ratio and OA Summary: Results of a study presented at the AAOS Annual Meeting in Orlando, Fla.

Its upper extremity is small, and is placed below the level of the knee joint which excludes it from that joint. At the lower extremity, it projects below the tibia and forms part of the ankle joint.

Why and how do we keep our bones strong? Our bones have many tasks. If not taken care of, bones can become weak and break. Broken bones are painful and surgery is sometimes needed.

Once broken, there can be long-lasting health problems. There are things you can do to keep your bones healthy and strong: Eat foods rich in calcium and Vitamin D; Get plenty of exercise; Practice good health habits.

The Relationship Between Tibia-Femur Length Ratio and OA

How do we exercise our bones? Bone is living tissue; it responds to exercise by becoming stronger.

Research indicates that when young people exercise regularly, they achieve greater peak bone mass than those who do not. Bone mass peaks for everyone sometime during the third decade of our life; after that, we begin to lose bone. Exercising allows us to maintain muscle strength, coordination, and balance — and those things help us to prevent falls and fractures.

Three Leg Bones: The femur, the tibia, and the fibula

Exercise and Osteoporosis Because you are working against gravity, weight-bearing exercises provide the most bang for your buck. One of THE most important, yet simple, exercises to do for bone strength is the squat.

A deadlift squat involves placing weights in both hands with arms fully extended down. The weights and arms remain in that position while you do as many squats as you wish. You can also do squats without the weights.

Proof that bones can heal Inmy husband joined the Navy. He was 19 years old and ready to live on his own. He became a corpsman and spent two years on a Naval Base in Japan. It is also known as the calf bone, as it sits slightly behind the tibia on the outside of the leg. It also helps to strengthen the tibia and provides support in the slight rotation of the knee.

The most common fracture of the fibula occurs at the bottom of the bone near the ankle. This can occur during direct impact, such as a fall, or from a twisting action, such as tripping while running.

The fourth bone of the knee is the patella. Commonly referred to as the kneecap, this nearly heart-shaped bone at the center of the knee helps extend the knee and protect the joint from impact. A tendon at the top of the patella and a ligament at the bottom hold the bone in place. As the knee bends, the patella slides along a groove in the femur.

Sometimes, due to numerous complications, the kneecap comes out of its groove and becomes dislocated, an injury known as patellar subluxation. Fibrous bands called ligaments hold these bones together. Two of the ligaments between the femur and tibia, the anterior cruciate ligament ACL and the posterior cruciate ligament PCLcreate a cross and provide stability to the joint.

Surrounding the connection of the bones, various elements such as bursa fluid-filled sacsfat pads, and cartilage pads strong, flexible tissue called menisciprotect the bones and keep the knee joint moving fluidly.

Injury, infection, and degeneration to these parts can be painful and cause mobility problems, but corrective surgery, rehabilitation, and medication can help ease problematic symptoms.
