Audible and/or palpable joint noises occurring during ambulation involving the knee are a common phenomenon. These sounds, which can manifest as clicks, pops, or creaks, often arise from the movement of tendons or ligaments over bony prominences within the knee joint, or from the movement of joint surfaces. For instance, a snapping sound may accompany the iliotibial band gliding over the lateral femoral epicondyle during knee flexion and extension.
The significance of such occurrences ranges widely. In the absence of pain, swelling, or functional limitations, these noises are frequently benign and require no intervention. Historically, some practitioners may have dismissed these noises; however, a more nuanced understanding acknowledges that persistent or changing sounds, particularly when accompanied by other symptoms, may indicate underlying pathology. Early recognition of potential issues allows for timely evaluation and management, which can contribute to preserving joint health and function.
