This research study is the first of its kind and will allow health care professionals and researchers to answer many questions about the reasons why anterior cruciate ligament (ACL) injury leads to knee pain and disability and osteoarthritis. We also hope that this study will be the beginning of new, more powerful and safer drugs to help patients with ACL injuries heal sooner and return to sports or daily activities pain free. Study participants will be recruited from the University of Kentucky and Vanderbilt University.

The purpose of this research is to gather information on how safe and effective Kenalog® is in alleviating knee pain following ACL rupture.

Further study details as provided by University of Kentucky:

Primary Outcome Measures:
  • Efficacy of Kenalog to alleviate knee pain [ Time Frame: Patients will be evaluated for changes in pain at 5 post-injury time points (1-2 days), 12-14 days, 2 weeks post-op, 4 weeks post-op and 6 months post-op) ]
    This trial will use the standardized patient self-report Knee Injury and Osteoarthritis Outcome Score (KOOS) instrument to assess pain and function in response to the intervention for acute ACL injury. This trial will supplement the KOOS with function score assessments from the International Knee Documentation Committee (IKDC) form for evaluation of knee ligament injuries

Secondary Outcome Measures:
  • Kenalog therapy improves levels of a panel of inflammatory (cytokine), meniscus and cartilage metabolism and oxidative stress biomarkers [ Time Frame: 1-7 days, 10-17 days after injury and at time of surgery ]
    Biomarkers to be tested include IL-1α, IL-1β, Collagen type I (NtxI) and collagen type II (CTXII) breakdown products, cartilage oligomeric protein (COMP) and glycomsaminoglycan (GAG) and Xanthine Oxidase. Additionally, the change in IL-1α/β levels in the IL-1Ra treated and placebo individuals will be evaluated specifically for association with pain and function outcomes.

Detailed Description:

Injury to the knee during sports participation often involves partial of full detachment of the 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, we hope to prevent and reduce the initial post-operative pain. The reduction of pain will allow for earlier movement of the knee joint and preparation for surgery. It may also reduce the risk to develop osteoarthritis in individuals with ACL injuries by treating them within 1-2 days after their injury.
