Risk Factors Comparison for Radial and Horizontal Tears

Abstract

Tears in posterior horn of medial meniscus mainly included horizontal tear, transversal tear, radial tear, complex tear, and bucket handle tear. We analyzed and compared the risk factors for radial tear and horizontal tear in the posterior horn of medial meniscus. A total of 407 consecutive cases who received arthroscopic treatment of medial meniscus tears were analyzed retrospectively. Among them, 103 cases were radial tear in posterior horn of medial meniscus and 107 were horizontal tear. Clinical data records included patients' age, gender, duration of symptoms, body mass index, trauma history, and slope angle of tibia, valgus angle of knee, and grading of cartilage (Outerbridge Grades) were collected and analyzed. In addition, multiple-factor nonconditional logistic regression was adopted to analyze the related risk factors in these two types of medial meniscus tears. The two groups have no difference in age, trauma history, slope angle of tibia, and duration of symptoms but have significant difference in gender, body mass index, and valgus angle of knee and grading of cartilage. Multiple factors analysis indicated that valgus angle, age, and grading of cartilage were risk factors in medial meniscus tears. Patients with posterior horn tear in medial meniscus have higher incidence among senile osteoarthritis, while radial tear was more likely to occur in elderly patients with knee-joint varus and serious cartilage degeneration.

Medial Meniscal Posterior Horn Tears Are Associated With Increased Posterior Tibial Slope: A Case-Control Study

“…33 Nevertheless, given the overall result of the between-group comparison including the VLT group, it could be suggested that the patients with greater PTS would be relatively vulnerable to a knee injury and more likely to have a trauma-related lesion, as in the relationship between the PTS and ACL injury. 28,31 Other between-subgroup comparisons did not show a significant difference in the PTS, consistent with the study by Wu et al 32 comparing the radial tear and horizontal tear in the MMPH and the study by Barber et al 4 comparing complex medial meniscal tears and other types of medial meniscal tear. The results of the present study are significant in that we compared not only among types of degenerative tear but also included patients without meniscal tear in a strictly controlled state.…”

“…There were also 2 studies that investigated the association between the PTS and meniscal tear patterns but did not compare with those without meniscal tear. 4,32…”

“…There were also 2 studies that investigated the association between the PTS and meniscal tear patterns but did not compare with those without meniscal tear. 4,32 This study was performed in a more controlled condition, only for MMPH tears in knees without ligamentous injury, given that the MMPH is the most common site of meniscal tears and is the area where the highest tension is applied. 22,27 Furthermore, the contralateral knee was included in the assessment to validate the comparability.…”

Modern Views on the Treatment of Patients with Injuries of the Medial and Lateral Menisci of the Knee Joint (Literature Review)

“…Досить часто такі розриви локалізуються на межі тіла та заднього рогу. Згідно з дослідженнями, радіальні розриви зустрічаються у чоловіків у віці 11-20 років та у жінок 51-70 років [22,23]. Як правило, такі розриви виникають внаслідок травми.…”

Identification And Validation of Pivotal Genes Related To Meniscus Senescence Based On Gene Expression Profiling Analysis And In Vivo And In Vitro Models Detection

“…The population-based cohort study found that the age is a major risk factor for meniscus tearing, especially in people over 40 years old [6,7]. Previous studies have shown that aging could cause compositional changes in the meniscus, which includes degeneration of collagens, cells, and proteoglycans [8,9].…”
