OBJECTIVE: To summarize the research progress of suture augmentation (SA) in anterior cruciate ligament (ACL) reconstruction. METHODS: A comprehensive review of recent literature about SA in ACL reconstruction at home and abroad was conducted. The efficacy of SA in ACL reconstruction was evaluated by examining the definition, biomechanics, and histological studies of SA, along with its clinical application status in ACL reconstruction. RESULTS: SA demonstrates significant advantages in enhancing the biomechanical stability of ACL grafts, reducing the risk of re-rupture, and accelerating postoperative recovery. Specifically, SA improves graft stiffness, ultimate failure strength, and cyclic stability, thereby diminishing the risk of early postoperative failure and joint instability. Histologically, it fosters remodeling and tendon-bone integration through early load-sharing mechanisms; however, stress shielding may interfere with natural remodeling processes, warranting further attention. Clinically, SA reduces graft failure rates and the need for revision surgeries, markedly improving knee joint stability and functional recovery in young patients. Nevertheless, its impact on graft maturation and potential complications remains controversial. CONCLUSION Despite the many advantages of SA in ACL reconstruction, future endeavors should focus on optimizing tensioning techniques, developing bioactive materials, and conducting large-scale randomized controlled trials to further elucidate its clinical value and scope of applicability, providing a more reliable solution for ACL reconstruction.

Objective To analyze the abnormal detectable rates of different kinds of blood test indexes before and after treatment in the patients with snake bite and to probe into the change condition of these indexes after different snake bite .Methods The inpa‐tients with clearly diagnosed what kind of snake bite in the past two years were selected as the research subjects .The multiple blood test indexes were determined before and after treatment in these patients .The abnormal detectable rates of these indexes were ana‐lyzed and compared among various snake bite patients .Results The different kinds of snake bite all could cause the different de‐grees of changes in some detection indexes among partial patients .Specially ,the detectable rates of WBC ,PT ,APTT ,TT ,D‐D ,CK , CK‐MB ,LDH ,Urea ,Cr and Cys‐C increase and PLT and Fbg decrease caused by viper bite were apparently higher than those caused by other kinds of snake bites (P<0 .05) .The detectable rates of CO2 increase and K+ decrease in the coral snake bite were apparently higher than those in trimeresurus gramineus ,cobra and viper bite (P<0 .05) .Conclusion Because the snake species and toxicities are different in the various snake bites ,so the caused changes and the abnormal detectable rates of blood test indexes also are different .

Objective To explore the change regulation of blood coagulation function before and after treatment of snake bite pa‐tients .Methods A total of 226 hospitalized patients with clear diagnosis belong to what kind of snakes in the past two years were selected in this study ,39 cases were bit by coral ,76 cases were bit by trimeresurus stejnegeri ,47 cases were bit by cobra ,24 cases bit by king cobra ,40 cases were bit by adder .Five blood coagulation indexes were determined before and after treatment various pe‐riods for these patients .The tested results were made to statistical analysis according to kind of snakes ,periods and disease condi‐tion .Results D‐D level obvious .rise before treatment for the severe cases patients of coral snake bite (P<0 .05) .Plasma prothrom‐bin time (PT) ,activated partial clotting enzyme live time (APTT) ,thrombin time (TT)and D‐D level rise and Fib level reduced be‐fore treatment for the severe cases patients of trimeresurus stejnegeri bite ,and Fib and D‐D level before and after treatment had sta‐tistical significant difference with the mild patients (P<0 .05) .Every index for the cobra and king cobra had no statistical signifi‐cant differences (P>0 .05) before and after treatment ,only D‐D level of the severe cases had statistical significance before treat‐ment in contrast to the mild cases of cobra bite (P< 0 .05) .The changes of 5 item blood coagulation indexes were all very large whether mild or severe for viper bite patients ,a number of comparisons had statistical significance difference (P<0 .05) whether before or after treatment and whether mild or severe for viper bite patients .Conclusion The bite of coral snake ,cobra and king co‐bra affect little for the blood coagulation function .The severe cases patients of trimeresurus stejnegeri bite might lead to more seri‐ous blood coagulation function abnormality but the recovery is faster after treatment .The viper bite might lead to maximum blood coagulation function abnormality and the recovery is slow after treatment .
