Weeping sinew refers to a medical condition characterized by the presence of excessive or abnormal secretion of synovial fluid in the knee joint. This condition is commonly associated with knee injuries or trauma, particularly damage to the anterior cruciate ligament (ACL). The term "weeping" is used to describe the phenomenon of continuous or excessive fluid discharge resembling tears or weeping.
The sinew, or the tendon connecting muscle to bone, primarily functions to transmit forces generated by muscle contractions to the bone. In the context of weeping sinew, it specifically refers to the tendons or ligaments surrounding the knee joint.
When a knee injury occurs, such as a tear or rupture of the ACL, the body's natural response is to produce excess synovial fluid. Synovial fluid is a viscous substance that lubricates and nourishes the joints, facilitating smooth movements. However, in cases of weeping sinew, this fluid is produced in excess or becomes trapped within the joint due to the injury.
Symptoms of weeping sinew may include swelling, pain, stiffness, and instability of the knee joint. It is important to note that this condition usually requires medical intervention, including proper diagnosis through physical examination and potentially imaging tests. Treatment options can range from conservative approaches, such as rest, ice, compression, and elevation, to more invasive procedures like surgery, depending on the severity of the injury and the patient's individual circumstances.
