Symptomatic torn discoid lateral meniscus in adults

Abstract

The purposes of this study were to report degenerative changes that coexist with a symptomatic torn discoid lateral meniscus in adults and to analyze the factors associated with the accompanied degenerative changes. From 1997 to 2008, 329 knees in the 305 patients were included. Associations between the status of the meniscus and the coexisting degenerative changes on the images and the arthroscopic findings were statistically analyzed. Marginal osteophyte was seen on conventional radiography in 118 patients (36%). Ninety patients (27%) had arthroscopically confirmed chondral lesion. Age, duration of symptoms, the type of meniscus, the type of tear and the magnetic resonance image classification were associated with the formation of the marginal osteophyte and chondral lesion on univariate analysis (P \ 0.05). After conducting multivariate analysis, the type of tear and magnetic resonance image classification had a statistically significant association with the severity of marginal osteophyte and chondral lesion (P \ 0.05).

Prognostic factors affecting the outcome of arthroscopic saucerization in discoid lateral meniscus: a retrospective analysis of 48 cases

“…But this finding is not supported by other studies including our study. Ahn et al [4] analyzed the factors associated with the severity of the marginal osteophyte formation on the conventional radiography using multivariate analysis, and they failed to prove this relationship. Similarly, Asik et al Bold p values with (*) represent significant correlation Musculoskelet Surg [14] compared the clinical results of patients who underwent arthroscopic saucerization before and after 12 months of presentation and again failed to show a significant difference.…”

“…drozkankose@hotmail.com however, the incidence of DLM is reported between 0.4 and 16.6 % in patients who underwent knee arthroscopy [3,4]. Clinical manifestations of lateral discoid meniscus are highly variable depending on the type of the discoid meniscus, the presence of an accompanying tear and the status of rim stability.…”

“…Previously, several authors investigated the outcomes of arthroscopic saucerization and reported promising results with few complications [3,4,6,[8][9][10][11][12][13][14][15][16][17][18][19]. However, prognostic factors affecting the final outcomes are not well studied in relevant literature.…”

Diagnostic criterion to distinguish between incomplete and complete discoid lateral meniscus on MRI

“…Deie et al reported the relationship between the type of osteochondritis dissecans and the type of DLM. Ahn et al suggested a significant correlation between the type of discoid meniscus and the accompanying chondral lesions in their univariate analysis. Kim et al also reported that there is a significant difference between the outcome and the type of DLM or the type of meniscectomy.…”

Short-term clinical outcomes of 42 cases of arthroscopic meniscectomy for discoid lateral meniscus tears

“…A discoid meniscus is an anatomical congenital anomaly which was considered to be a vestige of viviparous cartilage development of the knee (1,2). Diagnosis of the discoid meniscus has been improved by the MRI technique, and the incidence of discoid lateral meniscus of the knee in the Chinese population is 16–46% (3).…”
