The arthroplasty described by Weilby is a reliable procedure for the treatment of stage 2 and 3 basal thumb osteoarthritis. Although the technique provides good pain relief, optimal thumb mobility, and acceptable levels of grip and pinch strength in most cases, it is common to see the thumb collapsing because the interposed knot has disassembled. We have found a more effective way to prepare and stabilize that interposition material. With this modification, we have had less thumb subsidence than with the original technique.
