Efficacy Evaluation of the Combined Platelet-Rich Plasma and Hyaluronic Acid after Arthroscopic Joint Debridement in Treating Knee Osteoarthritis

OBJECTIVE: The study is aimed at observing the efficacy of the combined platelet-rich plasma and hyaluronic acid after arthroscopic joint debridement in treating knee osteoarthritis (KOA). METHODS: 126 patients with KOA admitted to the Affiliated People's Hospital of Ningbo University and Taizhou Orthopaedic Hospital from 2018-11 to 2021-11 were selected. All nominees were grouped by random drawing; group B (63 cases) received arthroscopic joint debridement while group A (63 cases) received platelet-rich plasma and hyaluronic acid based on group B. The following metrics are counted, including total efficiency, knee joint pain and function, inflammatory cytokines levels, and oxidative stress indicator levels; the complication rate is counted. RESULTS: The total effective rate of group A (93.65%) was higher than that of group B (77.78%) (P < 0.05), and there was no significant difference in the incidence of complications between the groups (P > 0.05). Three months after treatment, knee joint pain and function, inflammatory cytokine levels, and oxidative stress indicators levels in group A were better than in group B (P < 0.05). CONCLUSION: The combined platelet-rich plasma and hyaluronic acid after arthroscopic joint debridement in treating KOA can achieve significant effects, reduce knee pain, accelerate the recovery of knee joint function, relieve inflammation, and inhibit oxidative stress and has high safety.
