Arthroscopic diagnosis and treatment of anterior cruciate ligament impingement syndrome / 中国矫形外科杂志

ABSTRACT

[Objective]To investigate the mechanism and pathologic changes of anterior cruciate ligament impingement syndrome as well as its arthroscopic diagnosis and treatment.[Method]From January 2005 to June 2007,28 patients with a history of anterior cruciate ligament impingement were diagnozed and treated arthroscopically.The patients' clinical findings were mainly anterior patellar pain and limited knee joint.The reasons of anterior cruciate ligament impingement syndrome were indentified by routine arthroscopic examinationstraitness of intercondylar notch or osteophytes formation in 19 cases,old avulsion fracture in the tibial intercondylar in 4 cases,anterior cruciate ligament cyst in 3 cases,incorrect tibial tunnel placement on reconstructed anterior cruciated ligament in 2 cases.Different surgical procedures were carried out according to the results of the examinationjoint debridement and intercondyle's plasty;intercondyle's plasty and osteophytes resection;joint debridement and ACL cysts resection;ACL tibial eminence insertion reconstruction were performed.[Result]Twenty-eight cases were followed for an average of 15 monthes(6-34 monthes).The rate of good to excellent was 82.1%,recurrence was observed in 1 case.[Conclusion]The gradual constriction of the knee is mainly caused by the anterior cruciate ligament impingement syndrome.Arthroscopy is very valuable in diagnosis and treatment of anterior cruciate ligment impingement syndrome.It can also acquire whole assessment of the joint injuries and makes out reasonable treatment program to normal knee joint function.
