Summary:

      Injury to the knee during sports participation often involves partial or full detachment of
      the anterior cruciate ligament (abbreviated as ACL). ACL tears cause pain, swelling and
      inflammation. While the swelling and inflammation usually goes away in time, individuals with
      ACL injuries may experience pain and notice knee instability (knee slipping, etc.). Often
      surgery can repair or replace the ACL within the joint, allowing individuals the ability to
      walk or run again pain free or participate in sports. Unfortunately, osteoarthritis of the
      knee, which also causes pain and swelling, can occur in that same knee 10-20 years later for
      reasons which are not well understood.

      In this research study, the investigator hopes to reduce the initial pre-operative pain. The
      reduction of pain will allow for earlier movement of the knee joint and preparation for
      surgery. The investigator is interested to see if the use of Kineret does decrease the risk
      of developing arthritis in individuals with ACL injuries by treating them within 28 days
      after their injury.
