Effect of arthroscopic reconstruction of anterior cruciate ligament on the expression of serum osteopontin and CD44 / 中国综合临床

ABSTRACT

Objective To investigate the effect of arthroscopic reconstruction of anterior cruciate ligament on the expression of serum osteopontin (OPN) and CD44.Methods Ninety-six cases patients with joint cross ligament injury who were teated in Taihe Hospital Affiliated to Hubei University of Medicine from February 2013 to June 2015 were selected and randomly equally divided into treatment group and control group.Two groups were adopted arthroscopic surgical treatment,and the control group were given the singletunnel reconstruction,the treatment group were given the double-tunnel reconstruction.Results The IKDC scores of 3 months after operation in the treatment group and control group were (92.44±5.13)points and (85.25±4.67) points,both significantly lower than before operation ((57.24 ± 4.19) points,(57.10 ± 4.87)points;P ＜ 0.05)),while there was statistically significant difference between groups (P ＜ 0.05).The total complication rate after 3 months operation in the treatment group was 6.3％,significantly less than that of the control group (35.4％;x2 =5.838,P＜0.05).The OPN expression levels of before and 3 months after operation in the treatment group were (31.98±4.21) μg/L,(7.13±2.89) μg/L,and CD44 were (419.45±20.45) μg/L,(167.24± 18.46) μg/L,the differences were significant (t =34.214,21.774;P＜ 0.05).The OPN expression levels of before and 3 months after operation in the control group were (32.09 ± 3.98) μg/L,(15.98 ± 3.67) μg/L,and CD44 were (421.87 ± 19.45) μg/L,(245.98 ± 20.56) μg/L,the differences were significant (t=21.833,14.099;P＜0.05).There were significant differences on OPN and CD44 of after operation between the two groups (t =12.847,7.498;P＜ 0.05).Conclusion Compare to single-tunnel reconstruction,double-tunnel reconstruction for the anterior cruciate ligament endoscopic surgery can increase restore knee function and reduce postoperative complications,and its mechanism may effectively reduce the levels of OPN and CD44 expression.
