Abstract
The aim of this study was to study the clinical efficacy and prognostic factors after revision and reconstruction of anterior cruciate ligament. All the patients who underwent the first revision of anterior cruciate ligament (ACL) reconstruction in the department of sports medicine from January 2001 to December 2015 were collected. The demographic information, the first revision and reconstruction information of ACL, and the information during the first ACL reconstruction were collected. A total of 335 cases were included. Lysholm score, Tegner activity score, and IKDC subjective score at the last follow-up were significantly higher than those before operation. Compared with graft failure caused by sports injury, the postoperative scores of patients with revision due to life accidents or initial reconstruction techniques were significantly lower (P < 0.05). The postoperative Lysholm score of patients with femoral canal drilling through the tibial canal was lower than that of patients with anterior internal approach. The postoperative IKDC score of patients who underwent medial meniscus suture at the same time was higher than that of patients without meniscus combined injury. ACL revision can improve the stability and function of knee joint. Compared with the revision caused by life accident or technical reasons of primary reconstruction surgery, the patients with graft failure caused by sports injury have better postoperative recovery. Medial meniscus suture and anterior internal approach drilling of the femoral bone canal have a statistically protective effect on the clinical function after ACL revision.
Highlights
Anterior cruciate ligament (ALC) reconstruction of the knee is one of the most extensive operations in the field of orthopaedic sports medicine
Participants. e medical records of all patients who underwent anterior cruciate ligament (ACL) revision surgery in the Sports Medicine Department of the hospital from January 2001 to December 2015 were retrospectively studied. e inclusion criteria were as follows: (1) only ACL graft suture, partial bundle reconstruction, or original graft refixation were performed in the revision surgery; (2) primary reconstruction or revision reconstruction combined with posterior cruciate ligament (PCL) injury and lower limb fracture; (3) follow-up results
Autologous hamstring tendon and allograft were commonly used in the first ACL reconstruction, and autologous hamstring tendon and autologous bone patellar tendon bone were commonly used in the first ACL revision
Summary
Anterior cruciate ligament (ALC) reconstruction of the knee is one of the most extensive operations in the field of orthopaedic sports medicine. It can effectively improve the stability and function of the knee. Erefore, understanding the medium- and long-term clinical efficacy and its influencing factors after ACL revision surgery can optimize the treatment plan of revision surgery and scientifically adjust patients’ expectations for postoperative efficacy, which is of great significance to improve knee function and patient satisfaction. Patients undergoing ACL revision were retrospectively followed up to evaluate the medium- and long-term clinical efficacy after revision, including graft failure rate, ipsilateral or contralateral knee reoperation rate, postoperative infection rate, and subjective score and, at the same time, the sex, age, BMI, duration of disease, causes of first failure, revision graft selection, and the effects of drilling method, combined
