HIP

The AMIS (Anterior Minimally Invasive Surgery in Total Hip Replacement) approach is a true muscle-sparing surgical technique.

With the AMIS surgical approach the surgeon DOES NOT CUT MUSCLES, which aids a rapid recovery.

The anterior approach is the only technique which follows inter-muscular and inter-nervous planes to reduce the risk of injury to muscles, tendons, vessels and nerves.

AMIS is a surgical technique that will improve the quality of your life and hasten your recovery after a Total Hip Replacement (THR).

The surgeon can access the hip joint by different paths, following a “conventional” or a Minimally Invasive Surgical approach (MIS).

True MIS is characterised by the preservation of the muscles and tendons encountered during the hip joint capsule surgery and involves a small skin incision/scar.

AMIS (=Anterior Minimally Invasive Surgery) is true Minimally Invasive Surgery.

Other approaches, which are advertised as minimally invasive (ie. posterior, lateral, double incision), are purely reduced skin incision techniques and are associated with muscle and/or tendon damage as per ‘conventional’ approaches.

The anterior approach is the only technique which follows inter-muscular and inter-nervous planes to reduce the risk of injury to muscles, tendons, vessels and nerves. Possible muscular release is always reduced at minimum and anyway is less significant than with other surgical approaches.

The AMIS technique causes less surgical trauma than other techniques because NO MUSCLES ARE CUT, only displaced.

AMIS is a surgical technique that will improve the quality of your life and hasten your recovery after a Total Hip Replacement (THR).

The AMIS (Anterior Minimally Invasive Surgery) approach is a true intermuscular and internervous minimally invasive surgical technique.

AMIS DOES NOT CUT MUSCLES AND DOES RESPECT NERVES

AMIS can potentially provide you with the following benefits:

  • Decreased post-operative pain
  • Shorter rehabilitation
  • Shorter hospital stay
  • Small skin scar
  • Faster return to daily activities
  • Less blood loss
  • Reduced risk of dislocation (separation of the hip ball and socket)
  • Prevention of limping
The main benefits of a successful total hip replacement are reduction in hip pain, recovery of mobility and improvement in quality of life. Your everyday activities and your social life will no longer be limited by pain and reduced mobility.
KNEE

Medacta® believes in the importance of education: surgeons performing MyKnee have attended a training course hosted by the M.O.R.E. (Medacta®Orthopedic Research & Education) Institute. Find a specialized surgeon near your area.

Rehabilitation can start on the day of the operation, subject to your doctor’s approval.

You can resume weight bearing activities when comfortable for you to do so and discontinue using assistive devices as your comfort level increases.

Medacta® implants cover a wide range of sizes/designs. Your surgeon will discuss with you the best prosthesis to restore your knee functions.

The MyKnee procedure is elected for a wide number of patients, talk with your surgeon to determine if this procedure is the best option for you.

A month before the surgery the surgeon will ask you to have a diagnostic scan (CT or Magnetic Resonance) of your leg.

Medacta® will use the resulting images to create a plastic 3D model of your knee. This model will be analized by your surgeon to manufacture your personalized surgical instruments.

Moreover, 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.

MyKnee is a precision instrument which is tailored for each individual patient from a radiological image of their knee.

The MyKnee technology potentially enables the intervention of knee arthroplasty more accurate, faster and less traumatic.

The positioning of a knee prosthesis is performed using surgical instruments which prepare the bone to receive the prosthesis.

In the conventional procedures the surgical instruments are the same for all patients.

MyKnee is a surgical instrument which fits perfectly to your knee because it is tailored for you, allowing preparation of the bones to receive the prosthesis, respecting the characteristics of your anatomy.

The MyKnee enhances the benefits of a standard knee replacement offering more accurate, faster and less traumatic procedure, by the use of a surgical instrument tailored for the patient.

It has been proven that an accurate positioning of the prosthesis leads to an increased survival of the implant.

Moreover, MyKnee eliminates the need of medullary canal violation by producing customised extra-medullary jigs. Clinical studies demonstrate that the blood loss and the risk of embolism dramatically decrease if the medullary canal is left intact.

Finally, the use of the MyKnee technology is very simple and straightforward. It potentially allows the surgeon to reduce the operating time, thus decreasing the time under anesthesia and the risk of infection.

The main benefits of a successful knee replacement are reduction in knee pain, recovery of mobility and improvement in quality of life. Your everyday activities and your social life will no longer be limited by pain and reduced mobility.

MyKnee fits the shape of the knee accurately, allowing precise preparation of the bone for implanting the prosthesis. It has been proven that an accurate positioning may result in increased survival of the prosthesis. Of course, as with any surgery, individual results will vary. How long a knee replacement lasts—no matter how the procedure is performed—varies depending on a number of factors, including bone quality, patient weight and activity level and other health factors.

SPINE
Any surgical procedure comes with risks. Serious complications are rare and your surgical team will do everything possible to avoid issues arising. However, the most serious potential risks include

  • Paraplegia (Very rare – 1 in 1,000 to 1 in 10,000 chance)
  • Excessive blood loss
  • Continued progression of the curve after surgery
  • Failure of the spine to fuse
  • Infection

Currently, there is very little that can be done to prevent spinal deformities.

Sometimes it can happen. This depends on the sensitivity of the detectors at the points of control of the airport. All Medacta’s Spine implants are identified by a card called Implant Passport, provided by your surgeon after the operation. Carry it always with you and show it if necessary!

Yes, it is possible to have an MRI scan after your surgery. The imaging, however, will be disturbed to some extent by the metallic implants.

It depends on the type of deformity. If a specific cause is unknown, it is deemed “Idiopathic” (for example in Adolescent Idiopathic Scoliosis). Some forms of scoliosis however have a known source:

  • Congenital scoliosis (abnormally formed vertebrae at birth)
  • Neuromuscular scoliosis (nerves and muscles unable to maintain anatomical alignment eg. Cerebral Palsy, Muscular Dystrophy)
  • Genetic conditions (such as Osteogenesis Imperfecta, Down’s Syndrome)
  • Anatomical changes due to age, trauma or disease

Lifestyle factors and habits are not responsible for creating a spinal deformity. Carrying heavy school bags, sporting activity, poor posture or minor leg length differences do not cause scoliosis.

I only experienced very minor limitations after the operation, very little pain.
