The knee is capable of producing a variety of sounds clicks, pops, clunks, and grinding sensations that can range from barely noticeable to something that prompts immediate concern. These sounds are one of the more common reasons patients mention their knees in conversation with an orthopaedic specialist.
The experience of a knee making sounds is very common. For some people, it is simply a feature of how their joint moves and causes no discomfort or functional problem. For others, clicking or popping is associated with pain, swelling, or a change in movement, and in these situations it deserves closer attention.
Why Does the Knee Make Clicking or Popping Sounds?
The knee is a complex joint involving bones, cartilage, ligaments, tendons, and a range of soft tissue structures. Sound can originate from any of these during movement, and the cause is not always the same from one patient to another.
In many cases, clicking or popping without pain or other symptoms is not associated with any significant underlying change in the joint. Tendons and ligaments moving over bony prominences, or small movements of the joint surfaces during activity, can produce sounds that are entirely benign. In other situations, sounds that are accompanied by pain, swelling, or a sensation of catching or giving way may indicate that the joint warrants assessment.
Is Knee Clicking Always a Problem?
Not all knee clicking indicates a problem. Many people notice their knees clicking regularly without any associated pain, swelling, or change in the ability to move or use the joint normally. In these situations, the clicking is often not a cause for concern on its own.
What matters more than the sound itself is whether it is accompanied by other symptoms, and whether those symptoms are affecting the use of the knee.
When Should Knee Clicking Be Checked?
Knee clicking that is accompanied by pain, swelling, stiffness, or a feeling that the knee is catching or giving way is worth having assessed. Similarly, clicking that develops after an injury, or that represents a change from a pattern that was previously asymptomatic, should not simply be dismissed.
The concern is not the sound itself but what it may indicate about the structures within the knee. An assessment helps determine whether the clicking is a feature of normal joint movement or whether it reflects a change that warrants management.
Knee Clicking After an Injury
If clicking or popping develops after a knee injury whether a direct impact, a twisting event, or a fall it is worth seeking an assessment even if the immediate pain has settled. Injuries can affect the cartilage, ligaments, and other structures within the knee, and clicking that develops in this context may indicate that a structure has been disrupted.
An assessment that includes clinical examination and appropriate imaging helps determine whether the injury has affected the joint in a way that requires management.
Knee Clicking With Pain
Clicking that is accompanied by pain during or after activity is a combination of symptoms that warrants medical attention. Pain alongside clicking suggests that the structures producing the sound may be under stress or affected by an underlying change that is contributing to both symptoms.
The nature of the pain where it is felt, what aggravates it, whether it persists after activity or settles quickly provides useful information for the assessing clinician and should be described as clearly as possible during a consultation.
Knee Clicking With Swelling or Stiffness
Swelling in the knee, whether persistent or occurring after activity, in combination with clicking, is a pattern that warrants assessment. Swelling within the knee reflects a change in the joint that is not simply related to the sound, and understanding what is causing both symptoms together is important.
Stiffness alongside clicking particularly stiffness that has developed over time or is present in the morning is another combination that is worth discussing with an orthopaedic specialist.
Knee Clicking While Exercising
Clicking that occurs during exercise or sport is very common and is not always a sign of a problem. However, if exercise-related clicking is accompanied by pain, causes a catching or locking sensation, or leads to swelling after activity, these accompanying features are worth assessing.
Patients who notice that clicking during exercise is becoming more frequent, louder, or is newly associated with discomfort should raise this with a specialist rather than continuing to exercise through symptoms.
What Details Should You Notice About Knee Clicking?
When preparing for a consultation about knee clicking, noting the following details helps the clinician conduct a more focused assessment: when the clicking occurs and during which movements; whether it is associated with pain, swelling, or stiffness; how long it has been present and whether it has changed over time; and whether the knee has been injured previously.
How Can You Prepare for a Consultation?
Being prepared to describe what has been noticed when the clicking occurs, which movements produce it, and what other symptoms accompany it is the most useful preparation. Any previous imaging or investigations related to the knee are worth bringing to the appointment.
What If Your Knee Keeps Clicking?
Persistent clicking that has been present for some time without change, and without accompanying symptoms, may not require urgent assessment. However, if the pattern changes, if new symptoms develop, or if the clicking begins to affect confidence in using the knee, seeking an assessment is appropriate.
Can You Continue Your Usual Activities?
Whether to continue usual activities when knee clicking is present depends on whether the clicking is accompanied by pain, swelling, or a change in the knee's function. Clicking without other symptoms is generally not a reason to stop activity. Clicking with pain, swelling, or a sensation of giving way is a reason to seek assessment before continuing with activities that load the joint significantly.
When Should You See a Doctor for Knee Popping?
See a doctor when clicking or popping is accompanied by pain, swelling, or stiffness; when it developed after an injury; when the knee feels unstable, gives way, or locks during activity; when the pattern of clicking has changed significantly; or when it is affecting confidence in using the knee for daily activities or exercise.
