PTTD Surgery: Types, Risks, and What to Expect During Recovery

The word “surgery” is scary. If your doctor has mentioned it as a possibility for your PTTD, you’re probably feeling anxious—maybe you’re imagining the worst, or maybe you’re just tired of dealing with pain and want to get it over with. Either way, understanding what surgery involves can help you feel more in control of your situation.

Here’s the most important thing to know upfront: most people with PTTD never need surgery. That’s worth repeating. The vast majority of patients manage their condition successfully with conservative treatments like orthotics, physical therapy, and lifestyle changes. Surgery is typically reserved for cases where those approaches haven’t worked, or when the condition has progressed to a more advanced stage.

Do most people need surgery?

No. Most people with PTTD never go under the knife. The condition is highly treatable in its early stages, and even moderate cases often respond well to non-surgical approaches.

Surgery becomes a consideration when conservative treatments have failed after several months of consistent effort, when there’s significant tendon damage or deformity, or when pain is severely impacting your daily life. The decision to operate is always made after weighing the risks against the potential benefits—and your surgeon should walk you through that process thoroughly.

Types of PTTD surgery

When surgery is needed, there are several different approaches. The right one for you depends on your specific condition, the stage of your PTTD, your age, and your overall health.

Tendon procedures

The posterior tibial tendon itself is often the focus of surgical treatment. Tendon debridement involves cleaning up damaged tissue and repairing any tears. This is typically done for patients with partial but significant tendon damage.

If the tendon is too damaged to repair, a tendon transfer might be recommended. This procedure uses a tendon from another part of your foot—often the flexor digitorum longus—to replace the damaged posterior tibial tendon. The body adapts well to this rearrangement, and most patients regain good function.

In some cases, a tendon graft is used instead, where a donor tendon (from a cadaver or another source) replaces the damaged one.

Bone procedures

Sometimes the bones themselves need to be repositioned to properly support the arch. An osteotomy cuts and realigns bones to achieve this. The medial cuneiform osteotomy is a common choice for moderate PTTD, while calcaneal osteotomy shifts the heel bone to better support the arch.

These procedures are often done in combination with tendon surgery for the best results.

Joint procedures

For advanced PTTD with significant arthritis, fusion surgery (arthrodesis) might be necessary. This involves joining two or more bones together to eliminate painful movement in a damaged joint. Triple arthrodesis fuses three joints in the back of the foot. While this sounds drastic, it can be life-changing for patients with severe deformity and pain.

Gastrocnemius recession

Many people with PTTD also have a tight Achilles tendon, which puts extra stress on the arch. Gastrocnemius recession is a procedure that lengthens the calf muscle to reduce this tension. It’s often done alongside other PTTD procedures rather than as a standalone operation.

The surgical process

Here’s generally what to expect:

You’ll typically be under general anesthesia for the procedure. The surgery can take anywhere from one to three hours depending on what’s being done. Some patients stay in the hospital overnight, while others go home the same day.

After surgery, you’ll wake up with your foot in a splint or cast. You won’t be allowed to put weight on that foot for several weeks—this is critical for proper healing.

Recovery timeline

Recovery from PTTD surgery is a marathon, not a sprint. Here’s a general breakdown:

The first 2-4 weeks involve strict immobilization. You’re non-weight-bearing, meaning you use crutches or a knee scooter to get around. The foot is in a cast or splint to protect the surgical repairs.

Weeks 4-8 transition you into a walking boot. You might start putting some weight on the foot, but activity is still limited. Physical therapy usually begins during this phase to maintain flexibility without stressing the repairs.

Months 2-4 involve continued physical therapy and gradual return to normal activities. The boot comes off, and you start building up to full weight-bearing. Strengthening exercises become more intensive.

Month 4 onwards is the final phase. Most patients are back to most normal activities by this point, though full recovery can take up to a year. Some swelling and stiffness may persist for several months.

Risks and complications

Any surgery carries risks. For PTTD surgery, the main concerns are:

Infection is always a possibility with any surgery. Most are treatable with antibiotics, but serious infections are rare.

Nerve damage can cause numbness, tingling, or weakness in the foot. This usually improves over time but can occasionally be permanent.

Non-union or delayed union means the bones or tendons don’t heal as expected. This might require additional treatment.

Stiffness is common after foot surgery. Physical therapy helps, but some loss of flexibility is possible.

Blood clots (deep vein thrombosis) are a risk with any lower extremity surgery. Your surgeon will discuss preventive measures.

The good news: when PTTD surgery is performed at the appropriate stage by an experienced surgeon, success rates are generally high. Most patients experience significant pain relief and improved function.

Making the decision

If you’re facing the possibility of PTTD surgery, here’s my advice: get a second opinion. Talk to at least one other foot and ankle specialist. Ask about their experience with PTTD specifically, not just foot surgery in general. Ask what results they typically see with patients like you.

Understand what’s being done and why. There should be a clear explanation of how the procedure addresses your specific problem. Ask about the recovery process in detail so you can plan accordingly.

And remember: surgery isn’t the end of the road—it’s the beginning of a recovery journey that requires your active participation in physical therapy and following post-operative instructions.
