Incidence and treatment of intra-articular lesions associated with anterior cruciate ligament tears

Abstract

The aim of the study is to retrospectively review the patients admitted and treated in the "Alexandru Rădulescu" Orthopedics and Traumatology Clinic, Cluj-Napoca for an anterior cruciate ligament tear over a 2-year period and document the intra-articular lesions found at arthroscopy as well as the treatment used for these associated lesions. Patients and methods: The case records of 88 patients operated for anterior cruciate ligament tear over a period of 2 years were reviewed. There were 67 males and 21 females with a mean age of 28.9 years, ranging from 14 to 49 years. After recording the patient demographics, we documented all the intra-articular lesions found during knee arthroscopy, as well as all procedures undertaken concomitant with the ACL reconstruction. Results: 50 of the 88 patients (56.8%) had associated intra-articular lesions at the time of anterior cruciate ligament reconstruction. The most common injury found was a meniscus tear, 48 patients (54.5%) had a meniscal pathology at the time of ligament reconstruction, medial meniscus being the most frequent injured one, found in 37 patients. Meniscectomy and meniscus suture were the procedures performed for these lesions, meniscectomy being more frequent. Chondral defects were the next associated injuries found with an incidence of 15.9% of the cases. The medial side of the knee was the most common site of chondral pathology. Conclusions: ACL tears are frequently associated with other intra-articular lesions, especially medial meniscus tears and chondral defects affecting the medial compartment. Such pathology most often needs surgical attention during the anterior cruciate ligament reconstruction.
