Answer:

An artificial ligament is made of about 3,000 braided polyethylene fibers, with a strength of 3,000 to 3,500 newtons. It is very strong and will only tear under a force greater than 300 kg. Typically, patients can walk on the first day after ligament reconstruction surgery and return to sports after about 6 months. This allows for quick recovery of mobility and prevents muscle atrophy.

An artificial ligament is designed to remain permanently in the body. After implantation, fibrous tissues, bone cells, and collagen cells will form, adhere to, and grow along the artificial ligament, creating a complete and integrated structure.

While durable, an artificial ligament can still tear. Besides strong impacts, tears can be caused by surgical technique, subpar ligament material, or previous ligament surgery. Re-tearing can also occur if the patient doesn't follow the rehabilitation program correctly, returning to work or sports too soon or at too high an intensity.

Most ligament tears can be reconstructed. However, like any medical procedure, using an artificial ligament carries potential risks. Therefore, if you experience an injury, consult a medical facility specializing in sports medicine and orthopedic trauma for proper diagnosis and treatment.
