Could bunion surgery patients walk right away? trial puts it to the test
NCT ID NCT05534724
First seen Sep 11, 2026 · Last updated Sep 11, 2026
Summary
Researchers are testing whether people can put full weight on the foot immediately after a modified Lapidus operation, a common bunion surgery that fuses bones in the midfoot. The trial assigns 122 adults to either walk fully in a special post-op shoe or limit weight to 10 to 15 kilograms for six weeks. Everyone wears the shoe for six weeks, and researchers track function with a 100-point ankle score and pain on a visual scale. The goal is to see whether early walking is safe and helps recovery compared with the standard partial weight-bearing approach.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a rehabilitation plan of walking on the foot right after surgery versus putting only limited weight on it
- What this could lead to
- If walking on the foot right away proves safe, people recovering from Lapidus bunion surgery might return to daily activities sooner and spend less time on crutches.
- What could go wrong
- Putting full weight on a freshly fused joint could loosen the repair or delay healing, and this single trial in 122 people may not settle the question for everyone.
