After knee surgeries such as arthroscopy or cartilage repair, hyaluronic acid (HA) injections are increasingly used to support joint function and promote faster recovery. HA improves synovial fluid viscosity, reduces inflammation, and enhances cartilage protection.
Clinical studies suggest that intra-articular HA injections after knee surgery may help reduce pain, improve mobility, and support rehabilitation (PMC9837239, EOR-23-0040).
However, systematic reviews note variability among trials, with some indicating limited or short-term benefits depending on formulation and timing.
Early pain relief: Reduces postoperative inflammation and discomfort.
Joint stability: Restores lubrication and balanced load distribution.
Structural protection: Promotes chondroprotection and tissue healing.
Rehabilitation support: Facilitates early return to physiotherapy.
Hyaluronic acid injections can be a safe and biologically valuable adjunct therapy following knee surgery. Optimal outcomes depend on correct timing, dosage, and patient selection.
