Discoid Meniscus – A Review of Literature and Our Case Series

Abstract

Abstract Aim: The current study aims at the surgical outcome of the lateral discoid meniscus which is treated with knee arthroscopy, meniscal refashioning, and meniscal repair in various age groups. Materials and Methods: The study includes 7 patients (3 females and 4 males) with a mean age of 26.6 (Range 10 to 50 years). This is a retrospective type of study with a study period ranging from June 2018 to January 2024. Results: Patient satisfaction was excellent in all cases regarding pain, locking of the knee, Range of motion, and return to sports/daily activities. Diagnostic Arthroscopy confirmed the discoid meniscus abnormality in all the cases. Bucket handle type tear of the lateral menisci in 2 cases. Anterior horn tear in 1 case. Horizontal tear in 1 case. Unstable discoid meniscus in 3 cases. Meniscoplasty, removal of central part of meniscus, and sparing its periphery was done for all cases. Stabilization of the meniscus was done with meniscal repair in 4 patients with inside-out and all inside techniques. Visual analog score (VAS score) has significantly reduced from moderate pain (45-74)and mild pain (5-44 mm)to no pain (0-4 mm). Conclusion: Arthroscopic sauscerization, meniscoplasty alone, or additional stabilization with meniscal repair can provide excellent clinical outcomes in patients with symptomatic lateral discoid meniscus.
