Putty fills gap, aims to cut Post-Surgery pain in knee OA patients

This study tests whether filling the bone gap with a synthetic putty (AttraX Putty) during knee realignment surgery can reduce pain in the first week after surgery. About 40 adults with knee osteoarthritis will be randomly assigned to get the putty or standard surgery without a gap filler. The goal is to see if the putty leads to less pain, faster recovery, and fewer complications.
