Description of intervention(s) / exposure
The treatment course consisted of a continued series of three intra-articular injections of sodium hyaluronate (Orthovisc) administered during 3 consecutive weeks starting 3-weeks postoperatively (40 patients) into the affected (arthroscopied) knee joint. The HA used in this study was Orthovisc®, (30 mg sodium hyaluronate dissolved in 2 ml physiological saline; Anika Therapeutics Inc., Woburn, MA, USA).

Summary
Brief summary
Arthroscopic débridement and hyaluronan injections are two different interventions to treat knee osteoarthritis. Arthroscopic débridement, although controversial, is a common practice among orthopaedic surgeons in the treatment of knee osteoarthritis. There is evidence on the potential benefits of the use of Hyaluronan for knee osteoarthritis. We aimed to assess the further potential benefits of using Hyaluronan as an adjunctive therapy after arthroscopic débridement. In addition our control group (only arthroscopy) was aimed to give information on the benefits of only arthroscopic intervention.
