If you have thumb arthritis, you know how hard it can be to open a jar or hold a pen. Surgery can help. But what happens after surgery matters just as much. Can rehab really make a difference?
Scientists studied people who had thumb surgery. They wanted to see if rehab helped people get better. They also looked at two kinds of surgery. One removes a bone. The other puts in a fake joint. Here is what they found.
Key Findings at a Glance
- Research shows that both kinds of surgery can improve thumb pain and movement with rehab
- Prosthetic replacement (fake joint) helps you recover faster in the first weeks
- According to this study, after six months both surgeries give similar results
- Rehab plays an important role in getting your thumb working again
- Trapeziectomy (bone removal) causes fewer complications but takes longer to recover

What Is Thumb Arthritis and Why Does It Hurt?
Your thumb has a special joint at its base. This joint helps you pinch and grip. It is called the TM joint. TM stands for trapeziometacarpal. That is just a fancy word for the spot where two bones meet at the bottom of your thumb.
When this joint gets worn out, it hurts. You may find it hard to do simple things. Buttoning a shirt can feel impossible. Turning a key can bring tears.
You may be wondering why this matters. It matters because millions of people have this problem. You are not alone.
What Did the Study Do?
Scientists looked at 61 people who had thumb arthritis. These people had surgery between November 2023 and October 2024. Some had one kind of surgery. Others had another kind.
After surgery, some people did rehab exercises. Some did exercises on their own. Others did no rehab at all. The scientists wanted to see who got better faster. They also wanted to know if rehab helped.
They checked pain levels. They asked people when they could go back to work. They measured how well the thumb worked. They did this at one month and six months after surgery.
Here is where it gets interesting. The scientists found that both surgeries helped. But they worked in different ways.
What Are the Two Kinds of Surgery?
Let us look closer at the two surgeries.
Interposition Trapeziectomy
This surgery removes a small bone in your thumb. The bone is called the trapezium. After the bone is gone, the doctor puts soft tissue between the other bones. This keeps them from rubbing together.
This surgery takes longer to heal. But it causes fewer problems. In the study, 31 people had this surgery.
Prosthetic Joint Replacement
This surgery puts a fake joint in your thumb. The fake joint is called a prosthesis. It acts like your old joint. It lets you move your thumb.
People with this surgery get better faster. They can use their thumb sooner. In the study, 30 people had this surgery.
| Surgery Type | Number of Patients | Recovery Speed | Long Term Results |
|---|---|---|---|
| Trapeziectomy | 31 | Slower | Good |
| Prosthesis | 30 | Faster | Good |
Does Rehab Really Help After Surgery?
Yes. According to this study, rehab does help. Both groups got better when they did rehab. Their pain went down. They could move their thumbs more. Their hands worked better.
Rehab means doing exercises. These exercises help your thumb get strong again. They help you move it without pain. A therapist can teach you the right exercises. Or you can learn to do some on your own.
The scientists measured pain using something called VAS. VAS stands for visual analog scale. It is just a way to rate pain from zero to ten. Zero means no pain. Ten means the worst pain ever.
People in both surgery groups had less pain after rehab. They also scored better on a test called the DASH score. DASH measures how well your hand works in daily life.
What About People Who Did No Rehab?
Some people in the study did no rehab. They did not do as well. This tells us that rehab is important. It helps you heal better and faster.
In the trapeziectomy group, people who followed a rehab program did just as well no matter which rehab plan they chose. This means the key is doing some kind of rehab. The exact type may not matter as much.
Which Surgery Is Better?
That depends on what you need. If you want to get back to work fast, the prosthesis may be better. Research shows that people with a prosthesis had faster recovery of strength. They also felt happier with their thumb in the first few weeks.
But if you want fewer problems down the road, trapeziectomy may be better. It causes fewer complications. A complication is when something goes wrong after surgery.
Here is the good news. After six months, both surgeries gave the same results. People felt the same amount of pain. Their thumbs worked just as well. They were equally happy.
Studies indicate that the best surgery for you depends on your life and your needs. Talk with your doctor. Tell them what you do every day. Tell them what matters most to you.

Common Questions
How long does recovery take after thumb arthritis surgery?
According to medical evidence from this study, people with a prosthesis recover strength faster in the first weeks. People with trapeziectomy take longer. But by six months, both groups have similar results.
Do I need rehab after thumb surgery?
Yes. Research shows that rehab helps improve pain, movement, and hand function after both types of surgery. People who did rehab got better results than those who did not.
Which surgery has fewer complications?
The study found that trapeziectomy has a lower complication profile. This means fewer things go wrong. But prosthetic replacement allows quicker recovery.
Will I be able to use my hand normally after surgery?
Yes. Both surgeries improve hand function. With rehab, most people return to their normal activities. Some return to heavy work. The study measured this using the DASH score and found good improvements in both groups.
What This Means for You
If you have thumb arthritis, surgery can help. Both kinds of surgery work well. One helps you recover faster. The other causes fewer problems. But in the long run, they work about the same.
The most important thing is rehab. Doing exercises after surgery helps you heal. It helps your thumb get strong. It helps you do the things you love again.
Talk with your doctor about which surgery is right for you. Ask about rehab. Make a plan. You do not have to live with thumb pain forever.
Take it one step at a time. Healing takes time. But it is worth it.
