Summary

This study tests a new medicine called Allocetra for people with knee osteoarthritis. It is injected directly into the knee joint to see if it safely reduces pain and improves function. About 160 adults aged 45-80 with moderate knee arthritis will receive either Allocetra or a placebo. The goal is to measure pain relief and any side effects over 6 months.
