What term describes a squeaky, grinding sensation caused by friction between bone and cartilage?

The term that describes a squeaky, grinding sensation caused by friction between bone and cartilage is crepitus. This phenomenon occurs when there is a loss of smooth cartilage that normally allows for frictionless movement of joints. When cartilage wears down, bones may rub against each other, leading to audible sounds and sensations that can be described as grinding or crunching. This is commonly associated with various joint conditions, particularly osteoarthritis, where cartilage degeneration occurs.

Understanding crepitus is important in diagnosing and treating joint issues, as the presence of this noise can indicate underlying problems such as joint degeneration or injury. This distinction is vital for healthcare professionals assessing joint health and determining appropriate treatment plans for patients experiencing these sensations.
