[Objective]To evaluate the clinical efficacy of repair of old Achilles tendon injury with tendon autografts.[Methods]A ret-rospective study was conducted on 7 patients who had old Achilles tendon rupture repaired by tendon autografts from July 2016 to October 2021.The documents regarding to perioperative period and follow-up were evaluated.[Results]All patients had Achilles tendon repaired smoothly with operation time of(106.4±13.6)min,intraoperative blood loss of(35.3±12.3)ml,tendon defect of the broken end of(5.1±2.1)cm,and hospital stay of(11.6±1.3)days.All patients got incision healed in stage Ⅰ and followed up for(46.1±19.6)months.As time went from the point preoperatively,6 months postoperatively to the latest follow-up,the VAS score significantly reduced[(2.9±0.9),(1.7±0.8),(0.6±0.5),P＜0.001],whereas AOFAS score[(57.4±10.0),(81.1±4.5),(95.1±4.0),P＜0.001],ankle ROM[(27.4±3.0)°,(50.3±3.3)°,(56.6±3.5)°,P＜0.001],ATRS score[(41.1±5.8),(71.6±4.4),(93.3±4.2),P＜0.001]significantly increased,and triceps muscle strength[case,Ⅲ/Ⅳ/Ⅴ(7/0/0),(0/2/5),(0/0/7),P＜O.001]improved significantly.[Conclusion]For the old Achilles tendon rupture,repair with tendon autografts,such as peroneus longus or semitendinosus,can still achieve satisfactory clinical consequence.
