He specialises in primary (initial) and revision shoulder replacement surgery (arthroplasty), and arthroscopic (“keyhole”) shoulder surgery to access and repair a wide range of conditions, including shoulder reconstruction surgery.
A conventional total shoulder replacement mimics the normal anatomy of the shoulder; a plastic ‘cup’ is fitted into the shoulder socket (glenoid), and a metal ‘ball’ is attached to the top of the upper-arm bone (humerus).
In a reverse total shoulder replacement, the socket and metal ball are switched. The metal ball is fixed to the socket and the plastic cup is fixed to the upper-end of the humerus.
The main reason to consider a reverse total shoulder replacement is when there is arthritis of the shoulder joint and the rotator cuff tendons are torn or significantly damaged. This is the most common surgical indication for a reverse total shoulder operation. In this situation, the total reverse shoulder operation will give the patient significant pain relief and may also help with range of motion of the shoulder. While range of motion after a reverse prosthesis may not be completely normal, it is typically improved over the motion previously lost due to the arthritis and pain.
In conventional total shoulder replacement surgery, the damaged parts of the shoulder are removed and replaced with artificial components, called a prosthesis.
The treatment options are either replacement of just the head of the humerus bone (ball), or replacement of both the ball and the socket (glenoid).
Several conditions can cause shoulder pain and disability, and lead patients to consider shoulder joint replacement surgery.
Shoulder arthroscopy is a minimally-invasive procedure to inspect, diagnose, and treat problems inside the shoulder joint, such as osteoarthritis or tears.
It involves using small incisions (“keyholes”) to gain access to the shoulder joint, where a small flexible camera (arthroscope) can be inserted into the hole, along with small instruments to look inside a shoulder joint to diagnose or repair a particular condition.
Most arthroscopic procedures take less than an hour, however, the length of your surgery will depend on what your surgeon finds and what repairs are required. Your surgeon may inject fluid into the shoulder to inflate the joint. This makes it easier to see all the structures of your shoulder through the arthroscope. Once the problem is clearly identified, your surgeon will insert other small instruments through separate incisions to treat it.
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 shoulder 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.
