The Knee

The knee is a complex joint made up of three bones: the femur (thighbone), tibia (leg bone) and kneecap (patella).  It is a very finely tuned joint and it has highly complex movements of sliding, rolling, pivoting and gliding.  When there is a problem with your knee you may typically experience pain, swelling, catching, locking, stiffness, or limping.


The inside of the knee is lines with smooth cartilage, which allows for the knee surfaces to slide over one another.  The bones of the knee are held together tightly by ligaments and tendons, such as the ACL, PCL, MCL and LCL.  It is essential that these are working properly, otherwise you may have instability and difficulty walking.  The kneecap sits at the front of the knee, and this is responsible for providing a levering force, which allows your quadricep muscle to work efficiently as you are walking and running.  Between the bones, two shock absorbers (menisci) serve to cushion the impact when you walk.  

There are a wide variety of conditions which can affect your knee, and it is critical that you are evaluated by an orthopaedic specialist with a specific interest in knees to correctly diagnose and treat your condition.  Knee pain, stiffness, clicking, and swelling, can signify significant problems within your knee, and if you have a problem with your knee, please contact us at our Melbourne Orthopaedic Surgery to get you on the pathway to recovery – 03 5752 5020 or
