[edit] Discussion of Anterior cruciate ligament tear

  • ACL is the most commonly disrupted ligament of the knee, especially among athletes who participate in sports that involve rapid starting, stopping, and pivoting (i.e. soccer, basketball, tennis, and snow skiing).
  • ACL tears typically occur in the middle portion of the ligament.
  • Avulsion of the tibial attachment may be seen in younger patients.
