KOA
A total of 292 KOA patients treated from October 2020 to October 2021 were randomly divided into observation and control groups (n=146). Observation group was treated with ozone combined with articular injection of sodium hyaluronate, while control group was routinely given glucosamine hydrochloride tablets and articular injection of sodium hyaluronate. The treatment was performed once a week for 5 consecutive weeks. Their general data, treatment outcomes, visual analogue scale (VAS) score, Hospital for Special Surgery (HSS) knee score, inflammatory factor levels and hemorheological indices were compared.
