could be improved by further study into the posterior cruciate ligament treatment options currently available.
This is the view of Dr Matthew Matava, associate professor at the Department of Orthopedic Surgery at Washington University School of Medicine in Chesterfield, Missouri.
He explains that often people who have a tear in their posterior cruciate ligament do not seek treatment because the knee injury seems minor.
However, as time elapses the damage may cause a person's knee to be less strong and they may experience problems as a result.
Research points to new treatment options being more effective such as an inlay reconstruction and a two-bundle graft.
Dr Matava commented: "I like this procedure because I have had improved results compared to prior patients of mine that underwent the traditional method with the graft placed through the tibial tunnel."
He added that biomechanical evidence to support the findings of the study does exist and although studies comparing the methods have not yet been established, the benefits are clear.
The posterior cruciate ligament is a knee ligament that connects part of the tibia to the femur.
