Discoid lateral menisci: A report of 29 cases

Discoid Lateral Meniscus Incidence During Knee Arthroscopy

“…In a Greek study analysing discoid dysmorphy among 39 patients with DLM, 23 cases were attributed to complete type DLM, 15 were incomplete and Wrisberg type was observed in one case. (6) A Scandinavian report on this subject indicated that the complete and incomplete types of DLM were dominant (23). In their study, Sriptahi et al reported 69.4% complete type, 26.3% incomplete type, 4.2% "ring-shaped" discoid lateral menisci and no Wrisberg ligament type cases (9).…”

“…In a Swedish report by Abertsson et al, of 29 patients with DLM, 11 were male and 18 female. (23) In another study performed in India by Sriptahi et al, 41 male and 46 female patients (out of 87 patients) with DLM were studied. (9) Thus, these studies also failed to find a significant difference in the male-to-female ratio.…”

The discoid meniscus

“…The symptoms, however, are actually highly variable, depending on the type of the discoid meniscus, its location (medial or lateral), the presence of tear, and the status of rim stability [6,13,[23][24][25][26][27].…”

Discoid lateral meniscus

“…Although open meniscectomy has been reported to be satisfactory, arthroscopic surgery seems to give better results [1,2,13,22]. We believe that partial meniscectomy has the important advantage of leaving a rim of meniscus which has a biomechanical function, and our results of this technique are encouraging.…”

“…The first report of arthroscopic meniscectomy for a discoid meniscus was in 1982 [13], with other papers following [1,2,4,6,7,8,9,13,15,20,22].…”
