PURPOSE OF REVIEW: The discoid lateral meniscus is an abnormal variant that can lead to pain and mechanical symptoms. This review aims to summarize the clinical outcomes after surgical management of the discoid lateral meniscus. Procedures included saucerization/meniscectomies, repair, or meniscus allograft transplantation. RECENT FINDINGS: A total of 52 articles were included, consisting of 4,503 patients (4,784 knees). Weighted preoperative and postoperative Lysholm scores were 57.8 and 88.6, respectively, with 100% of studies (27/27) finding a significant improvement in scores postoperatively. Weighted preoperative and postoperative IKDC scores were 59.6 and 87.3, respectively, with 88.9% of studies (8/9) finding a statistically significant improvement in scores. Weighted preoperative and postoperative Tegner scores were 4.8 and 7.3, respectively, with 100% of studies (5/5) finding a statistically significant improvement in scores postoperatively. Weighted preoperative and postoperative VAS scores were 5.3 and 3.2, respectively, with 100% of studies (5/5) finding a statistically improvement in scores postoperatively. Amongst patients with reported values, 209 (6.6%
range 0-23.7%) suffered retears, while there were 290 reoperations (6.0%
range: 0-36.7%). Complications included persistent pain, mechanical symptoms, or swelling (n = 115
2-4%). Studies to date have reported good outcomes overall following surgical management of the discoid lateral meniscus, with significant improvements in PROMs. However, retear and reoperation rates within the literature have been reported to be as high as 23.7% and 36.7%, respectively.
