the shape of the articular surface
The definition of joint stability is the resistance that is offered by the musculoskeletal tissues surrounding the skeletal joints. The subsystems used for joint stability are active, passive, and neutral.
Mobility and stability in a joint are interdependent - optimal joint function requires a balance between the two. Mobility allows for a range of motion, while stability helps maintain proper alignment and control movement to prevent injury. Improving mobility without sacrificing stability and vice versa is important for joint health and function.
The ligaments which connect the bones in a joint provide the greatest stability
There may be more than two, but the size of the acetabulum with regard to the head of the femur has an effect on stability. Also, the size and condition of the ligaments holding the joint together have a definite effect on the stability of the joint. I can think of a third possibility too; the health of the bones at the joint. Severe arthritis or other degenerative bone issues will also play a role in the stability of the hip joint.
Yes, the shallow socket of the shoulder joint allows for greater movement of the humerus but sacrifices some stability compared to a deeper socket. To compensate for this, the shoulder joint relies on surrounding ligaments, tendons, and muscles for stability during movement.

Ligaments provide stability to the knee joint by connecting bones together, while tendons connect muscles to bones, allowing for movement and support in the knee joint.
The medial collateral ligament (MCL) provides medial stability to the knee joint while the lateral collateral ligament (LCL) provides lateral stability.
Increased joint stability refers to the ability of a joint to maintain its proper alignment and function during movement, reducing the risk of injury. This stability can result from various factors, including strong surrounding muscles, ligaments, and tendons that support the joint. It is essential for optimal performance in physical activities and daily movements, as well as for preventing issues like dislocations and strains. Enhanced joint stability can be achieved through strength training, flexibility exercises, and balance training.
The stability of the ankle, or talocrural joint, largely depends on the ligaments that hold it together.
The meniscus, which is made of fibrous cartilage, adds stability to the knee joint. It acts as a cushion between the bones of the knee and helps distribute weight evenly across the joint.
In the shoulder joint, stability has been sacrificed to provide the most freely moving joint in the body. The articulating bones provide minimal joint stability because of the size and "fit" of the articulating surfaces. The major stabilizing forces are soft tissue, in particular the tendons of the rotator cuff muscles (via muscle tone).
