Introduction The knee is the largest and most complex joint of our body. It has a very difficult function: carrying our body weight. Therefore, it is not surprising that the knees are the joints which are most vulnerable to injuries or to developing degenerative joint diseases, such as gonarthrosis (arthrosis of the knee). One of the consequences of any joint disease is pain. Statistics show that roughly one third of Americans over the age of 45 suffer knee pain. Knee pain limits your daily activities, affects your mood, your health, and overall, your general wellbeing! YOU WANT TO GET RID OF...

1 - The knee and gonarthrosis KNEE ANATOMY The knee joint is comprised of three bones: the femur, the tibia and the patella. The leg movement is driven by the thigh muscles, the biggest of which is the quadriceps, located in the front of the thigh. The thigh and shin bones are connected by ligaments, which give stability to the knee joint. The surface of the femur, tibia and patella, where the bones come into contact, is coated with a smooth tissue called articular cartilage. The cartilage, together with a substance called synovial fluid, prevents the bones from rubbing against each other and...

ARTHROSIS OF THE KNEE In cases of arthrosis, or gonarthrosis, the cartilage deteriorates and the bones start rubbing directly against each other. The result is joint pain, which worsens day by day, and limits motion. In the case of advanced ostheoarthritis, your doctor may suggest that you undergo a total knee replacement. KNEE ARTHROSIS SUCCESSFUL KNEE REPLACEMENT CAN RESULT IN DRAMATIC PAIN RELIEF AND IMPROVEMENT IN THE KNEE JOINT FUNCTION. CARTILAGE WEAR (PAIN)

2 - Total knee replacement WHAT IS A TOTAL KNEE REPLACEMENT? A total knee replacement surgery aims at substituting the bone and cartilage of the joint that has been damaged by arthrosis with plastic and metallic components. The surfaces of the thigh and shin bones are replaced with high-resistant metallic components, called the femoral component and tibial baseplate. A plastic insert is implanted between the femoral component and the tibial baseplate. It replaces the cartilage function, allowing the thigh and shin bones to slide on each other. All materials used in a total knee replacement are...

WHY TOTAL KNEE REPLACEMENT? With almost 50 years of history, total knee replacement surgery is a very common and safe procedure for the treatment of severe arthritis. Approximately 1,000,000 knee replacements are performed annually worldwide. The main benefits of a successful total knee replacement are: Reduction of knee pain Pain may be rapidly and dramatically reduced, potentially eliminated! You may radically improve the mobility of your knee. Improvement in quality of life Your everyday activities may no longer be limited by pain and reduced mobility!

3 - Conventional procedures and Myknee The positioning of a knee prosthesis is achieved using surgical instruments to prepare the bone for implanting the prosthesis. CONVENTIONAL PROCEDURES In conventional procedures, the surgical instruments are the same for all patients. Conventional instrumentation must be adjusted by the surgeon during the procedure in order to achieve satisfactory positioning for each individual. MYKNEE: THE INNOVATION MyKnee is a 3D Printed surgical instrument which fits your knee accurately, because it is tailored for you. Medacta, after analyzing a diagnostic image of...

6 - Getting ready for your operation TEST & CHECKS Your doctor may ask you for blood and urine tests and possibly a cardiogram prior to your surgery. In addition, before undergoing your total knee replacement, your doctor will prescribe a complete physical examination to assess your condition and to ensure that there are no factors that could interfere with your surgery. CHECK YOURSELF 1. Check your skin If your knee and leg have any skin infections or irritation, contact your orthopaedic surgeon prior to surgery: he or she will tell you how best to prepare your skin for surgery. 2.
