TSA vs RSA in Glenohumeral Osteoarthritis
This study is looking into which of two common shoulder replacement operations, called Total Shoulder Arthroplasty (TSA) and Reverse Shoulder Arthroplasty (RSA), is better for older people with shoulder arthritis. Shoulder arthritis happens when the smooth cartilage in your shoulder joint wears away, causing pain and difficulty moving. Both TSA and RSA are operations to replace the worn-out parts of the shoulder joint with new, artificial ones. The researchers want to compare these two procedures in people aged 65 and over to see which one leads to better quality of life and improved function in the long term. This is important because understanding the best treatment can help doctors decide which surgery is most suitable for you.

¿De qué trata este estudio?
This study is looking at people who have shoulder arthritis, which is a condition where the smooth surfaces at the ends of your bones in the shoulder joint wear down over time. This wear and tear can make your shoulder painful and stiff, making everyday activities difficult. Two common operations to help with this are Total Shoulder Arthroplasty (TSA) and Reverse Shoulder Arthroplasty (RSA), where parts of the worn joint are replaced with new, artificial ones.
In a TSA operation, the surgeon replaces the 'ball' and 'socket' parts of the shoulder joint, trying to keep the natural shape of your shoulder. This surgery often works very well, but sometimes there can be problems, especially if the bone of the socket (called the glenoid) has worn away unevenly. An RSA operation is a bit different – it's like reversing the ball and socket, changing their positions. This type of surgery is often used for older patients, especially if there's damage to the muscles around the shoulder (the rotator cuff) or more severe arthritis. While RSA can greatly improve movement and reduce pain, doctors are still learning about its long-term effects.
Currently, there haven't been many studies directly comparing these two operations in older people. This research aims to fill that gap. By carefully comparing TSA and RSA, the study hopes to provide doctors with clearer information about which type of surgery might offer the best results for people aged 65 and over with shoulder arthritis. The main goal is to find out which operation leads to a better quality of life and helps people use their arm more effectively.
Puntos clave
- This study compares two shoulder replacement surgeries (TSA and RSA) for people over 65 with shoulder arthritis.
- It aims to find out which surgery leads to a better quality of life and improved arm function.
- Participation involves either a TSA or RSA surgery, randomly assigned.
- You'll have follow-up appointments for up to 5 years to assess your recovery.
- The study helps doctors understand the best treatment options for older patients with shoulder arthritis.
¿Quién puede ser elegible?
To be considered for this study, you would typically be 65 years old or older and have long-lasting shoulder arthritis that hasn't improved with other treatments like pain medication, physiotherapy, or changing your activities. Doctors would also need to see clear signs of advanced arthritis in your shoulder on scans. Your shoulder socket should also be in a certain position, which doctors call having 'equal to or less than 15 degrees of glenoid retroversion'.
There are also reasons why you might not be able to join. For example, if you have an active infection, a different kind of shoulder problem called 'rotator cuff arthropathy', or severe muscle weakness around your shoulder. You also wouldn't be able to take part if you have other serious health problems that might make surgery risky, are pregnant, or have a mental health condition that makes it hard to understand the study. Lastly, if you've had previous surgery on the same shoulder or cannot commit to the follow-up appointments, you would not be eligible.
¿Podría este estudio ser adecuado para ti?
Responde estas preguntas rápidas para ver si puedes ser elegible. Esto es solo una guía: el equipo de investigación toma la decisión final.
- Are you 65 years old or older?
- Do you have shoulder arthritis that hasn't improved with other treatments?
- Have you NOT had previous surgery on the affected shoulder?
- Do you NOT have an active infection or other serious health issues?
- Are you willing and able to attend follow-up appointments for up to 5 years?
¿En qué consiste la participación?
If you decide to take part in this study, you would receive either a Total Shoulder Arthroplasty (TSA) or a Reverse Shoulder Arthroplasty (RSA) operation. Which surgery you get would be decided randomly, like flipping a coin. After your surgery, the research team would check in with you several times over a period of up to 5 years. During these visits, you would likely answer questions about your shoulder pain, how well you can use your arm, and your general quality of life. These check-ups will happen at specific times, such as 24 months and 5 years after your operation. The total duration of your involvement in the study would be up to 5 years.

Preguntas comunes
What is shoulder arthritis?
Shoulder arthritis happens when the smooth lining (cartilage) in your shoulder joint wears away, causing pain and stiffness.
What is the difference between TSA and RSA?
Both are shoulder replacement surgeries. TSA replaces the 'ball' and 'socket' in their natural positions. RSA reverses their positions, which is often used for certain types of shoulder problems or in older patients.
¿Podré elegir qué cirugía tendré?
No, in this study, which surgery you receive (TSA or RSA) will be decided randomly, like drawing lots.
¿Cuánto tiempo estaré involucrado en el estudio?
You would be involved in the study for up to 5 years, with follow-up appointments to check on your recovery.
¿Qué pasa si cambio de opinión sobre participar?
You are free to leave the study at any time, for any reason, without it affecting your care or your relationship with your doctors.
