Summary

This study compares two surgical methods (single-row vs. double-row repair) for people with chronic Achilles tendon pain that hasn't improved with non-surgical treatments. Researchers will measure pain, function, and costs in 166 adults aged 18-75 to determine which approach provides better outcomes and value.
