To learn more about knee injuries, we turned to
Jay Lieberman, MD, professor and chair of the Department of Orthopaedic Surgery at the Keck School of Medicine of USC. Dr. Lieberman is a hip and knee joint replacement expert at USC Orthopedic Surgery at Keck Medicine of USC.
He provided the following insight regarding knee cartilage and what to do if you have a knee injury.
What is cartilage and what purpose does it serve?
Cartilage is the tissue at the end of the bones and in your joints. Cartilage is a firm tissue that allows you to have pain-free range of motion of your joint.
What can you do to prevent an injury in the knees?
The following tips will help prevent injury and become more important with age:
Stretch before you play.
Incorporate strengthening of the quadricep and hamstring muscles into your exercise program.
Ice muscles after activity.
Maintain an appropriate weight to reduce the pounding on the knees during activity.
If you were diagnosed with a tear in your knee cartilage, what is the process to recovery?
Depending on the degree of your injury, you will likely be given a set of guidelines for recovery after visiting with your orthopaedic surgeon, which may include:
Prescribed physical therapy
Home exercise program
In many instances, this treatment solves the problem.
If you still have pain, then your physician may try to directly relieve the inflammation in the joint with an injection (e.g., cortisone, hyaluronic and platelet-rich plasma).
If you have a knee injury, make an appointment with an orthopaedic specialist. To learn more about USC Orthopaedic Surgery, visit
