Knee surgery recovery boosted by simple injection, study finds

NCT ID NCT07476508

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tested whether a hyaluronic acid injection into the knee or an oral chondroitin sulfate supplement could help people recover faster after arthroscopic surgery for a torn meniscus. About 290 adults were randomly assigned to standard rehab alone, rehab plus the supplement, or rehab plus two injections. The main goal was to measure knee function and pain 12 weeks after surgery using a standard questionnaire.
