Researchers discover new ligament in the knee

Discovering a new part of the body in the knee could mean breakthrough in the treatment of cruciate ligament injuries

Belgian surgeons have discovered a new part of the body in the knee. The mysterious ligament could be related to cruciate ligament injuries and their chances of recovery. The two researchers wanted to find out why, despite cruciate ligament surgery, many patients still have symptoms after the procedure. The starting point for her investigation was an article by a Frenchman, almost 150 years old, in which another band in the knee was suspected. The Belgians now provided anatomical evidence of the structure.

Unknown knee ligament suspected almost 150 years ago The discovery of the new knee ligament could lead to a breakthrough in the treatment of cruciate ligament injuries. Because up to now, many patients have had symptoms even after an operation.

The knee joint - a so-called rotation angle joint - is the largest joint in the human body and consists of bones, joint cartilage, tendons, ligaments, muscles and other joint structures. Among other things, it enables walking, running, jumping, standing and sitting. The impairments in the case of injuries to the knee are correspondingly large. Because in addition to knee pain, there are usually also restrictions on movement.

One of the most feared knee injuries is cruciate ligament problems. Cruciate ligament tears occur particularly in sports such as soccer or skiing. In addition to surgery, such an injury usually results in lengthy rehab. It often takes many months for the knee to be fully operational again. In addition, there are often persistent complaints about the stability of the knee. A cruciate ligament tear is therefore particularly dramatic for professional athletes. A tear in the anterior cruciate ligament causes the joint to lose its stability by allowing the shin to slide over the front of the thigh bone. However, the newly discovered ligament in the knee could lead to a breakthrough in the treatment of precisely this problem.

Belgian surgeons Steven Claes and Johan Belleman from the University of Leuven wanted to find out why patients after cruciate ligament surgery often complain about persistent knee problems. Her research was based on an almost 150 year old article by French surgeon Paul Ferdinand Segond. The doctor suspected another knee ligament as early as 1879. Claes and Belleman now confirmed the Frenchman's suspicions. In 40 out of 41 examined human knees, the two Belgians discovered a mysterious band that is responsible for the internal shin rotation. As a result, an injury to this "anterolateral ligament" (outer band) could be responsible for the persistent symptoms, the researchers suspect.

Anatomical Society praises the discovery of the new ligament in the knee
According to the University of Leuven, the anatomical society has described the discovery of the new volume as "very refreshing". She is also said to have praised the two doctors for "reminding the medical world that despite the development of the latest technologies, knowledge of human anatomy has not yet been exhausted."

"This research could challenge current medical thinking about serious cruciate ligament injuries and signal a breakthrough in the treatment of patients with serious cruciate ligament injuries," the university said. Claes and Belleman now want to devote themselves to the development of a new surgical technique to treat injuries on the newly discovered ligament. However, it will very likely still be years before the researchers can present concrete results. The two surgeons report on the new tape in the current issue of the journal "Anatomy".

Discovering a new part of the body in the eye In June of this year, researchers discovered a new part of the body in the eye. Professor Harminder Dua from the University of Nottingham reported on his research results in the journal "Ophthalmology". According to this, the human cornea consists of six instead of five layers as previously assumed. The discovery of the so-called "Dua" layer could facilitate operations such as corneal transplantation in the future.

With the new band in the knee, a new part of the body was discovered for the second time this year. However, some critics suspect that in both cases already known structures have been renamed. (ag)
