According to a Chicago Tribune article by the Mayo Clinic, the crunching sound from a knee is called crepitus. Crepitus is caused by the rubbing of cartilage on the surface of the joint or soft tissue around the knee. If there are no other symptoms, then no specific treatment is required.Know More
If pain accompanies the crunching sounds, its source is usually scar tissue, a meniscus tear or a tendon moving over a bony prominence located within the knee joint. Crepitus usually occurs when squatting, using stairs or getting out of a chair.
While crepitus is not a concern, cartilage can become rough and wear down, leading to arthritis. Strengthening the quadriceps muscle by walking, biking and swimming helps to reduce the risk of additional knee problems. A doctor or physical therapist can suggest additional exercises with or without weights that can be beneficial. Left untreated, knee conditions can lead to pain, joint damage and disability, according to the Chicago Tribune.
According to the Mayo Clinic, symptoms that can accompany knee pain include swelling, stiffness, redness, weakness, popping or crunching noises and an inability to straighten the knee fully. A patient should seek medical attention if the knee is unstable, cannot bear weight or has a visible deformity.Learn more about Bones
The knee is proximal to the ankle, and the ankle is distal to the knee. Proximal and distal are both anatomical words of location. Proximal means nearer to the point at which the structure originates or attaches, while distal means further from those points.Full Answer >
The kneecap, also called the patella, is found in front of the knee joint, which is the junction between the femur, the upper leg bone, and the tibia, the lower leg bone. Flanking the kneecap are the medial epicondyle of the femur and the lateral epicondyle of the femur. Just beneath them are the lateral condyle and the medial condyle of the femur.Full Answer >
Treating a shoulder for a popping sound depends on the cause, but many shoulder strains and tears can be treated with mobility exercises, according to WebMD. Common strains that produce a popping, cracking or clicking sound include rotator cuff injuries and superior labrum tears, also known as SLAP tears.Full Answer >
The tibia, patella and femur are joined together at the knee to form a hinge joint, according to WebMD. The bones are held in place at the knee with an elaborate system of ligaments, and they are buffered from each other by thick pads of cartilage.Full Answer >
