Objective The theory of uneven settling of the knee joint provides a new idea for the surgical treatment of knee osteoarthritis(KOA).The objective of this study was to investigate the clinical advantages of superior fibular osteot-omy combined with arthroscopic debridement in the treatment of medial compartment osteoarthritis of the knee joint com-pared to arthroscopic debridement alone.Methods The data of 125 patients with medial compartment osteoarthritis of the knee joint who completed treatment in Jinhua Hospital of Traditional Chinese Medicine from January 2021 to June 2023 and were followed up for ≥6 months were collected.According to different treatment methods,they were divided into the control group(72 cases with arthroscopic debridement alone)and the study group(53 cases with superior fibular osteotomy combined with arthroscopic debridement).The changes of femoral tibial angle(FTA),tibial joint space an-gle,knee range of motion(ROM),hospital for special surgery(HSS)score and synovial fluid interleukin-6(IL-6)and interleukin-1β(IL-1β)were compared between the two groups,and the incidence of surgery-related complications were analyzed.Results Six months after surgery,the levels of FTA[(180.21±1.90)° vs.(182.89±1.75)°],tibial joint space angle[(1.58±0.37)° vs.(3.09±0.61)°]and IL-6 and IL-1β in synovial fluid of knee joint in the study group were lower than those in the control group.The ROM[(91.23±7.05)° vs.(82.86±6.72)°]and HSS scores[(74.50±7.25)points vs.(65.12±6.37)points]were higher than those of the control group(P＜0.05),and the im-provement of knee joint function was better than that of the control group(P＜0.05).There was no significant difference in the incidence of complications between the two groups(P＞0.05).Conclusion Upper fibular osteotomy combined with arthroscopic debridement is an effective treatment for medial compartment osteoarthritis of the knee joint,which can significantly improve the lower limb force line,reduce inflammatory injury of the knee joint and improve mobility func-tion,with good safety.
