Knee Surgery

Specialist Knee Surgeon

Dr Michel Genon performs a range of knee surgery procedures.

He specialises in knee joint replacement surgery and arthroscopic (“keyhole”) knee surgery to address a range of underlying conditions. He employs the latest techniques when performing both types of knee surgery.

Areas of Expertise

Knee Replacement Surgery

Surgical Approaches Used

Knee replacement surgery (knee arthroplasty) is required to fully or partially resurface a knee joint that no longer functions correctly or causes excessive pain, usually as a result of arthritis. Dr Genon perform primary (initial replacement) and revision knee replacement surgery.

Dr Genon uses a lateral (side) incision when performing knee joint replacement surgery. This aims to avoid the common numbness at the front the knee which occurs with the traditional midline incision. The incision aims to make kneeling more comfortable after knee replacement.

He employs the sub-vastus approach to gain access to the knee joint, which is less invasive on the quadriceps during surgery (leaving the muscle entirely intact), which benefits recovery times.

He uses a tourniquet during knee surgery only for brief periods and only if necessary, to minimise damage to muscles under the tourniquet.

He uses periarticular injection (PAI) (also known as local infiltration analgesia), which involves administering local anaesthetic and analgesics (pain relief) into the tissue of the surgical field prior to surgery. Several studies have validated the benefit of PAI on post-operative pain relief.

At the completion of a knee replacement, a “Pain Buster” will be left in the knee. This is a simple balloon filled with local anaesthetic which drips into the knee for the first two- three days after surgery.

Knee Arthroscopy

Surgical Approaches Used

Knee arthroscopy uses keyhole incisions and is required when the surgeon wants to look inside a knee joint to diagnose a particular condition, remove a loose body from the knee joint or to perform surgery on an underlying damaged ligament, cartilage or meniscus.

Knee arthroscopy is a minimally-invasive procedure that uses small incisions (“keyholes”) to gain access to the knee joint, where a small flexible camera (arthroscope) can be inserted into the hole, along with small instruments to look inside a knee joint to diagnose or repair a particular condition, such as ligament rupture, meniscus tear or to remove a loose body.

Robotic Surgery

Dr Genon has undertaken specific up-skilling in robotic surgery, which offers orthopaedic surgeons access to the latest, precision-guided knee replacement surgical technology.

This technology aims to improve the accuracy and alignment of the joint implant being used during knee replacement surgery, which is known to improve the implant’s longevity and also help to produce a more consistent ligament and soft tissue balance.

The robot builds a plan based on 3-dimensional imaging of the patient’s anatomy taken a couple of weeks prior to surgery. The robot assists the surgeon in making precise bone cuts formulated from the scans. The surgeon has to show the robot where all parts of the patient’s relevant anatomy is in space. The surgeon also controls all of the robotic instruments by hand in real time. But the robot will tell the surgeon if where he or she is heading is even minutely divergent from the plan.

Frequently Asked Questions

Yes. He consults and operates in both the private and public hospital systems and maintains a busy public hospital roster, which confers the benefit of maintaining up-to-date surgical skills.

Many people with conditions seen by Dr Genon are best managed without surgery. All surgery carries risks. Dr Genon takes a conservative approach to surgery and will exhaust all non-invasive options available before considering surgery, or as guided by the scientific evidence. He is considerate and respectful and will take the time to listen to you, and to jointly determine the best course of action.

For those that need surgery, Dr Genon is an advocate of ‘short-stay’ joint replacement. He aims to give all patients early and rapid return-to-function through the use of minimally-invasive surgical techniques and the most advanced technology available. Some of Dr Genon’s knee replacement patients may be discharged on the day of their operation if they meet certain criteria and wish to do so. He reminds his patients that it is not a race, but that patients will be discharged when considered safe to go home from both a surgical and allied health point-of-view.
