Arthroscopy is a specialized branch of Orthopaedics in which the operation is performed through very small key holes with the help of miniaturized cameras.
The word arthroscopy comes from two Greek words, "arthro" (joint) and "skopein" (to look). The term literally means "to look within the joint."
Ligaments bind two bones in such a way that the joints can move in a restricted way. They prevent excessive and abnormal movement in the joints and also provide protection from the dislocation.
Ligament injury or ligament tear is caused due to excessive bending or torsional force along a joint. The ligament fails to hold the joint in place and gives away. Ligament injuries are commonly known as "ligament sprain".
There are 3 grades of ligament injuries depending on the severity of the tear.
Almost any joint can have ligament injury. However few joints are more susceptible to these injuries. Joints which frequently suffer from ligament injuries are:
Ligament injuries are frequently missed as they are not visible on x-ray. A missed grade II or III sprain cam cause prolonged discomfort to the patient.
Thorough clinical examination can help in diagnosing the injury. MRI scan can pick up ligament injuries.
Treatement depends on the grade of injury and the joint involved.
Some ligaments with grade II of III injuries never heal by themselves (e.g.- Anterior cruciate ligament of the knee). These ligemants require surgical intervention. Read about ACL injuries under Arthroscopy.
