Which condition might result from a lack of cartilage in joints?

Osteoarthritis is a degenerative joint disease characterized by the breakdown of cartilage, which results in pain, swelling, and reduced mobility in affected joints. Cartilage serves as a cushion between bones, facilitating smooth movement. When cartilage is lacking or damaged, bones can rub against each other, leading to inflammation and pain. This condition is commonly associated with aging but can also result from repetitive stress on the joints or previous injuries.

In contrast, a ruptured ligament may occur due to trauma or stress but does not directly relate to cartilage degradation. Hip dislocation refers to the displacement of the femur from the hip socket, typically due to a traumatic event rather than a cartilage deficiency. A muscle strain results from overstretching or tearing of muscle fibers, which is fundamentally different from joint-related cartilage issues. Thus, osteoarthritis is the most directly linked condition that arises from a deficiency of cartilage in the joints.
