Brief 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.

Primary Outcome Measures :
  1. Change of Knee Injury and Osteoarthritis Outcome Score (KOOS) Symptom Score Between Groups [ Time Frame: 1 year ]
    KOOS symptoms scores range from 0 to 100, with higher scores indicating less severe symptoms.

Secondary Outcome Measures :
  1. Change in CTX-II Levels From Injury to Time of Surgery [ Time Frame: time of surgery ]
    CTX-II levels measured by ELISA

Other Outcome Measures:
  1. MRI T1rho Changes [ Time Frame: 1 year ]
    MRI: T1rho values in Medial and lateral femoral condyle as well as medial and lateral tibial plateau

  2. Change in Knee Injury and Osteoarthritis Outcome Score (KOOS) Quality of Life (QOL) Score Between Groups [ Time Frame: 1 year ]
