Mean follow-up and results
Perkins et al[18]4412.4 (5-17)DLMArthroscopic meniscus repairAt 19 months: Saucerization and repair of discoid lateral meniscus tears in the pediatric population have good outcomes with low rates of reoperation
Anderson et al[28]21 (22 knees)12.8 (9-16.6)DMMArthroscopic saucerization; repair for torn menisciAt 24 months: Tears were present in over half of knees with discoid medial menisci, and reoperation was more common in knees that underwent repair of tears than those without repair
Feroe et al[29]8 (12 knees)13.8 (7.8-19.8)DMMArthroscopic saucerization; repair for torn menisciAt 25.8 months: Symptom resolution is common short-term, but long-term outcomes include recurrent meniscal tears
Dai et al[23]29Not availableDLMGroup A (14); PRP augmented; Group B (15) non-PRP augmentedAt 24 months: No significant difference observed in the Lysholm score, the Ikeuchi grade and the VAS score for pain at the last follow-up between the two groups
Ng et al[24]24 (24 knees)14 (8-21)DLMMeniscoplastyAt 84 months: Lysholm score; Preop: 53 (11-95) vs postop: 100 (60-100); Ikeuchi grade; 23 patients (excellent), 1 patient (good)
Johnson et al[26]11 (12 knees)9 (6-14)DLMMeniscopexyAt 4.5 yr: Lysholm score, 91 (86-100)
Wang et al[27]18Not availableDLMGroup A (8) MAT; Group B (10) MEAt 12 yr: No difference in Lysholm, IKDC, Tegner or VAS scores among both groups. Compared to meniscectomy, MAT achieved similar long-term symptom relief and superior chondroprotection in discoid meniscus patients
Table 3 Good and unfavorable prognostic factors
Good prognostic factorsMale sex
BMI < 18.5
Age of onset < 25 yr
Symptoms duration < 24 months
Unfavorable prognostic factorsIncreased work intensity
Increased severity of cartilage lesion
Preoperative cartilage instability
Smaller width and thickness of the remnant meniscus
