“…Kim et al58) assessed the mid-term clinical and radiological outcomes of discoid lateral meniscus treated by partial or total meniscectomy and found that partial meniscectomy was associated with better radiographic results after a 5-year follow-up. In a long-term follow-up study (mean, 10.1 years), Ahn et al59) also reported that subtotal meniscectomy was associated with increased degenerative changes compared with partial meniscectomy with or without repair. Lee et al62) found better radiological results after partial meniscectomy than subtotal/total meniscectomy in a mid-term follow-up, but clinical results did not differ significantly between treatment types.…”

“…Recently, Yoo et al54) found that Lysholm scores increased from a mean of 70.0 to a mean of 91.6 at the final follow-up irrespective of the meniscectomy method (partial or subtotal) after a mean of 4.7 years. Ahn et al59) reported in their long-term follow-up study (mean, 10.1 years) that 94% of patients had excellent or good clinical results; however, progressive degenerative changes appeared in 40% of patients. Some authors have described good clinical results of meniscal allograft transplantation after total meniscectomy for a torn discoid lateral meniscus60).…”

“…Many authors have reported good clinical results after partial meniscectomy with or without meniscus repair over short-, mid-, and long-term follow ups30,32,49,50,54,56–59) (Table 1). Ahn et al32) reported in their study with a minimum 2-year follow-up (mean, 51 months) that arthroscopic partial meniscectomy with peripheral repair was effective for treating symptomatic discoid lateral menisci.…”

“…In addition, removing a greater amount of meniscus has been associated with increased contact pressure on the cartilage and thus an increased risk of cartilage degeneration58). Several studies have found that the results of partial meniscectomy are better than those of total meniscectomy both clinically and radiologically58,59,62). Kim et al58) assessed the mid-term clinical and radiological outcomes of discoid lateral meniscus treated by partial or total meniscectomy and found that partial meniscectomy was associated with better radiographic results after a 5-year follow-up.…”

There is a greater incidence of discoid meniscus in Asian countries than in Western countries, and bilateral discoid menisci are also common. The discoid meniscus may be a congenital anomaly, and genetics or family history may play a role in the development of discoid menisci. Because the histology of discoid meniscus is different from that of normal meniscus, it is prone to tearing. Individuals with a discoid meniscus can be asymptomatic or symptomatic. Asymptomatic discoid menisci do not require treatment. However, operative treatment is necessary if there are symptoms. Total meniscectomy leads to an increased risk of osteoarthritis. Therefore, total meniscectomy is generally reserved for rare unsalvageable cases. Partial meniscectomy (saucerization) with preservation of a stable peripheral rim combined with or without peripheral repair is effective, and good short-, mid-, and long-term clinical results have been reported.

The diagnostic utility of radiographic signs of complete discoid lateral meniscus remains controversial. This study aimed to investigate the diagnostic accuracy and determine which sign is most reliably detects the presence of a complete discoid lateral meniscus in children. A total of 141 knees (age 7‐16) with complete discoid lateral meniscus and 141 age‐ and sex‐matched knees with normal meniscus were included. The following radiographic signs were evaluated: lateral joint (LJ) space, fibular head (FH) height, lateral tibial spine (LTS) height, lateral tibial plateau (LTP) obliquity, lateral femoral condyle (LFC) squaring, LTP cupping, LFC notching, and prominence ratio of the femoral condyle. Prediction models were constructed using logistic regressions, decision trees, and random forest analyses. Receiver operating characteristic curves and area under the curve (AUC) were estimated to compare the diagnostic accuracy of the radiographic signs and model fit. The random forest model yielded the best diagnostic accuracy (AUC: 0.909), with 86.5% sensitivity and 82.2% specificity. LJ space height, FH height, and prominence ratio showed statistically large AUC compared with LTS height and LTP obliquity (P < .05 in all). The cut‐off values for diagnosing discoid meniscus to be <12.55 mm for FH height, <0.804 for prominence ratio, and >6.6 mm for LJ space height when using the random forest model. On the basis of the results of this study, in clinical practice, LJ space height, FH height and prominence ratio could be easily used as supplementary tools for complete discoid lateral meniscus in children.
