PIP Joint Replacement Info Evidence Consent

Q: Can a finger joint really be replaced?

Yes. The middle (PIP) joint and the knuckle (MCP) joint can be replaced with a small silicone or pyrocarbon implant that relieves pain while preserving movement. The fingertip (DIP) joint is the exception — it is small and pinch relies on its stability, so it is almost always fused rather than replaced. A finger replacement is a smaller operation than a hip or knee replacement, but the principle is the same: the worn joint surfaces are removed and an implant takes their place.

Q: Should I have the joint replaced or fused?

Both relieve the pain reliably; the difference is movement versus stability. Replacement keeps the finger bending, which matters most for the ring and little fingers and for the knuckle joints, and for tasks like making a fist or gripping a rail. Fusion gives a stable, strong, pain-free but stiff joint, and is preferred for the index finger PIP joint and for high-load joints where pinch strength matters more than movement. The decision is made joint by joint at the consult, taking account of which finger, the bone quality on X-ray, and how the hand is used.

Q: How long does a finger replacement last?

Silicone implants have been used for finger joints for decades and have a long track record; they can fracture or wear over many years, but are straightforward to revise. Pyrocarbon resurfacing implants aim to preserve more natural movement and bone, with good medium-term results reported. As with any implant, heavy manual loading shortens its life, which is part of why the replacement-versus-fusion choice is weighed against how the hand is used. Longevity and the small chance of needing a revision are discussed individually before surgery.

Q: Will my finger bend normally after a replacement?

The aim is a comfortable finger with useful, not perfect, movement — typically a functional arc that lets you grip and make a fist, rather than the full range of a normal joint. How much movement returns depends heavily on the early hand-therapy programme, the starting stiffness and deformity, and the joint involved. The trade-off is favourable compared with fusion, which gives a permanently stiff (though stable and pain-free) joint. Realistic expectations for the specific finger are set out at the consult.

Q: How much does finger joint replacement cost? What does Medicare cover?

The operation is performed under regional or general anaesthesia at Mater Private Hospital Rockhampton, so a separate anaesthetist gap applies on top of the surgeon and hospital fees. The practice quotes the surgical fee in writing before booking — the Medicare item, the rebate and the out-of-pocket gap each shown separately. Implants are typically covered by private health funds; patients without private cover can be quoted self-funded. Surgery does not proceed without itemised written informed financial consent — the fees page explains the full process.

PIP joint replacement addresses painful arthritis in the middle finger joint when non-surgical options fail.

Why this operation has been suggested

Your surgeon has suggested a proximal interphangeal joint replacement, often called a PIP joint replacement. This surgery replaces the damaged joint in your finger with an artificial one to treat wear-and-tear arthritis. It is typically offered when non-operative options have not provided enough relief from pain or stiffness.

This operation aims to give you better motion and stability while reducing pain. It is a reliable option for the index finger, though it is less common for the long finger. Most patients return to work after a median of 8 weeks. While infection is uncommon, about 1 in 5 patients may need revision surgery within 5 years. The main goal is to restore function and provide long-term pain relief so you can use your hand more comfortably.

Before the operation

You will need to fast before your surgery and stop taking certain medicines as your surgeon advises. Please arrange for someone to drive you home and wear comfortable clothing. You may need X-rays, blood tests, or an anaesthetic review to check your health and plan the best care. Your surgeon will perform the operation through a single open incision over the joint. This approach allows direct access to replace the damaged bone with a new implant. You should bring a list of all your current medications to the hospital.

On the day

You will arrive at the hospital and meet your surgeon and the anaesthetist. This operation is done under general anaesthetic. You will be fully asleep for the operation. Some patients may also have a regional nerve block for post-operative pain relief — the anaesthetist decides on the day based on your individual circumstances.

Your surgeon will make a single conventional cut over your finger to reach the joint. You will then be moved to the operating theatre. After the surgery, you will wake up in recovery. Your team will monitor you closely before you go to your room.

What the operation involves

Your surgeon will make a single cut over the front of your finger joint. This open approach gives clear access to the area that needs repair. For some procedures, the joint is positioned slightly bent to allow better access to the tissues inside.

Inside, your surgeon removes the worn-out joint surfaces and replaces them with new parts. This surface replacement creates a smooth, stable joint that moves better than older options. In some cases, a small sling of tissue is tightened to support the finger. If needed, the surgeon may also fuse the smaller joint below it to help your finger move more freely.

Once the new joint is in place and working well, your surgeon closes the cut with stitches. These stitches are usually dissolvable or can be removed later. A dressing is applied to protect the area as you begin to heal.

After the operation

You will wake up in a recovery ward where your pain is managed with general medication. Your hand will be wrapped in a dressing, and you may wear a simple sling or brace for support. Your surgeon uses a single incision over the finger to perform the surgery. You will likely go home the same day, but someone must stay with you for the first 24 hours. You can begin moving your fingers early to protect the tendon repair. Most patients return to work after a median of 8 weeks. Some may feel minor pain for up to 3 months if you had tenderness before surgery.

Recovery

You will feel some swelling and soreness in your hand for the first few weeks. This is normal as your body heals from the single incision made over your joint. If you had tenderness before surgery, you might notice minor pain for up to 3 months. Your surgeon will guide you on how to manage this discomfort at home.

Your recovery involves a controlled motion program to help you move your finger safely. You will work with an occupational therapist for about twelve weeks to protect the tendon repair while regaining movement. You may wear a sling or brace to keep your finger in a comfortable position, often bent between 20 and 30 degrees. Simple tasks at home are possible once the swelling settles and you can grip without pain.

Your journey is unique, and your timeline may differ from others. Your surgeon and physiotherapist will adjust your plan as your movement returns. You will progress slowly toward full function, ensuring your joint remains stable and mobile. Trust the process and follow your team's advice for the best outcome.

What can go wrong

Most patients do well, but problems can occasionally happen. Your surgeon and the team monitor you closely to spot any issue early.

Sometimes the long finger is not a good candidate for this joint replacement. If you have this finger, your surgeon will discuss if the risks are too high for you.

Reoperations are common after this surgery. The most frequent reason is a problem with the tendon that straightens your finger. You might notice you cannot straighten your finger fully or feel a sudden weakness in the hand. Call your surgeon immediately if this happens.

Some joint replacements may need revision surgery within five years. You might also need more than one operation to fix the joint. If your finger becomes painful again or feels unstable, tell your surgeon right away.

Infection is uncommon after this procedure. However, if you notice redness spreading from the wound, deep throbbing pain that does not ease with simple painkillers, or a fever, contact your clinic immediately.

If you have severe stiffness in your finger from Dupuytren disease, complications may occur. You might feel increased swelling or pain that does not improve. Your surgeon will discuss the best plan to manage this.

If you have arthritis in multiple fingers, the risk of problems is similar to having just one finger replaced. You should still report any new pain or loss of movement to your team.
