Intraarticular Injection of Botox and Hyaluronic Acid in Knee Osteoarthritis

24. juni 2026 opdateret af: Mohammed Said ElSharkawy, Tanta University
This study aims to compare the efficacy of intra-articular injection of Botulinum toxin and hyaluronic acid on pain in knee osteoarthritis.

Studieoversigt

Detaljeret beskrivelse

Osteoarthritis (OA) is a widespread musculoskeletal disease and a leading cause of chronic disability. Conservative estimates state that up to 240 million people worldwide suffer from it. Knee osteoarthritis (KOA) is associated with chronic inflammation that causes persistent oxidative damage, which subsequently leads to joint degeneration.

Therefore, intra-articular (IA) therapies might be an alternative and safe treatment for these patients.

IA injection of hyaluronic acid (HA) is still a controversial treatment for knee osteoarthritis and comparative studies of HA versus more established treatments are warranted.

Botulinum toxin (BTX), produced by the bacterium Clostridium botulinum, acts on both sensory and motor neurons. Irreversible binding of BTX to presynaptic receptors of motor endplates inhibits acetylcholine release.

Knee Injury and Osteoarthritis Outcome Score (KOOS)
Tidsramme: 3 months after the interventions
The Knee Injury and Osteoarthritis Outcome Score (KOOS) is self-administered and assesses five outcomes, Pain (nine items); Symptoms (seven items); Activities of Daily Living Function (17 items); Sport and Recreation Function (five items); Quality of Life (four items). A Likert scale is used and all items have five possible answer options scored from 0 (No problems) to 4 (Extreme problems) and each of the five scores is calculated as the sum of the items included.
