This review was undertaken to better understand the debate regarding the issue of osteoarthritis associated with anterior cruciate ligament (ACL) injuries, from a surgical and biomechanical standpoint. Much of the current debate focuses on contributory surgical factors and their relative roles in increasing or decreasing the risk of future osteoarthritis development, primarily highlighting the controversy over whether reconstructive surgery itself is necessarily protective. This review addresses the evolution of ACL reconstruction techniques over time, and with a view to thoroughly examine the role of surgery, outcome differences in procedural technique are reviewed, with a focus on open versus arthroscopic methods, graft choice and the use of a double versus single bundle reconstruction technique.
Moreover, other potentially important contributory factors are identified and discussed, such as intrinsic biomechanical alterations sustained at the time of initial injury, and how these may have a more significant role with regard to future osteoarthritic changes in the knee than previously attributed.
