FAQs

Which joint, the hip or the knee, is more stable? ›

Common knee problems are sprained ligaments, arthritis, and tendonitis. The hip is the region on each side of the pelvis. It is a ball-and-socket joint that allows motion and provides stability needed to bear body weight. The hip is one of the most stable joints in the body.

The joint cavity contains synovial fluid secreted by the synovial membrane (synovium), which lines the articular capsule.

As with all of the structures that from the knee they are under most tension and therefore more stable in an extended (closed packed) position in comparison to the laxity present in a flexed position (open packed).

The shoulder is our most mobile, yet least stable joint. Its tremendous range of motion makes the shoulder less stable, and it is generally more prone to injury and dislocation than our other joints.

The hip is a ball (femoral head) and socket (acetabulum) joint. Unlike the shoulder, the hip joint has more bone to bone congruency, leading to stability and better weight-bearing ability. However, with the additional stability, the hip loses mobility, and there is much less freedom of movement than the shoulder joint.

Image 4: Types of Synovial Joints: The six types of synovial joints allow the body to move in a variety of ways. (a) Pivot joints allow for rotation around an axis, such as between the first and second cervical vertebrae, which allows for side-to-side rotation of the head.

Answer: The type of joint that allows movement of the palm right and left is a **hinge joint**. Hinge joints are formed where two or more bones come together and allow movement in a single plane, much like a hinge on a door.

Not only is the knee structurally less stable than the hip, it's also far more restricted.

The most stable joints are sutures. Sutures are synarthrodial joints which means that they are immovable. These joints are seen where the bones of the skull come together. For example, the sagittal suture is found between the right and left parietal bones in the skull.

The hip joint is extremely strong, due to its reinforcement by strong ligaments and musculature, providing a relatively stable joint. Unlike the weak articular capsule of the shoulder, the hip joint capsule is a substantial contributor to joint stability.

Is the knee joint stable or unstable? ›

The knee joint the biggest joint in the human body, and it is also subjected to enormous strain every day. In order to guarantee stability in the knee, it is supported by cruciate and collateral ligaments as well as muscles spanning the joint. In addition, a large capsule surrounds the entire knee.
