Arthrocentesis is a procedure in which a physician uses his or her own power to adjust the movement of a patient’s joints for health care purposes. The person is usually placed in a comfortable position where they can relax and allow the joints to move freely. The Physical Therapist will use their hands to locate the joints that need to be mobilized and apply the required force in the appropriate direction through his hands. Joint release is the careful use of skillfully graded forces to move the joint in the desired direction. Unlike stretching of muscular joints, joint sliding is often used to improve movement and normalize joint function. Joint release also serves to control pain. When the movement of a joint is limited, structural and functional changes occur in the area. Cartilage nutrition within the joint begins to decrease and other joints begin to move excessively to compensate for the stiffness. These neighboring joints begin to deteriorate due to overuse. The muscles surrounding the stiff joints lose their ability to contract and relax. Over time, the entire region is associated with dysfunction around the stiff joints. This is why the help of joint release is needed. Joint release can help in treating joint stiffness, impaired mobility and other problems. The operation needs to be performed by a specialized doctor.
