Abstract: 【Abstract】〓Objective〓To evaluate the clinical efficacy of arthroscopic debridement combined with sodium hyaluronate for knee osteoarthritis (KOA). Methods〓214 cases of KOA patients from March 2013 to March 2015 in our hospital were assigned to control group (106 cases) and treatment group (108 cases). Patients in control group was treated by arthroscopic debridement, and those in treatment group underwent arthroscopic debridement combined with intra-articular injection of sodium hyaluronate. The knee function scores (Lysholm score) at preoperative,3, 6, 12 months postoperation and the clinical excellent and good rates were compared between two groups. Results〓There were no significant differences in Lysholm scores between the two groups before operation (P>0.05). The Lysholm scores in the two groups after operation were significantly higher than that of before operation (P<0.05). The Lysholm scores of the treatment group 3, 6, 12 months after operation were significantly higher than those of the control group (all P values less than 0.05). At 3, 6, 12 months of postoperation, the excellent and good rate of the treatment group was 80.56%, 87.04%, 82.41% respectively, and was significantly higher than that of 67.92%, 72.64%, 68.87% in the control group (all P values less than 0.05). There were no significant differences in the incidence rate of complications (P>0.05). Conclusion〓Arthroscopic debridement combined with sodium hyaluronate for KOA can significantly improve the knee function, it have certain advantages in short-term curative effect, but the clinical efficacy of med-term and long-term needs further study.
