Final answer:

An ACL tear usually presents with symptoms such as knee instability, swelling, and pain. It can be caused by a strong blow to the knee, resulting in tearing of the tibial collateral ligament, damage to the medial meniscus, and rupture of the ACL. Treatment involves arthroscopic surgery and the use of a patellar ligament graft.

Step-by-step explanation:

An ACL tear usually presents with symptoms such as knee instability, swelling, and pain. The tear can occur due to a strong blow to the knee, which can cause the tibial collateral ligament to tear, damage to the medial meniscus, and rupture of the anterior cruciate ligament (ACL).

A moderate blow to the lateral knee can result in stretching or damage to the tibial collateral ligament and damage to the medial meniscus. A powerful blow to the lateral knee can cause a "terrible triad" injury, involving tearing of the tibial collateral ligament, medial meniscus, and ACL.

Treatment for an ACL tear often involves arthroscopic surgery to repair or reconstruct the torn ligament, with the use of a portion of the patellar ligament as a replacement. The surgical procedure allows for a rapid recovery and improved knee stability.
