Posterior Horn Repair Augmented With the Central Portion of Thickened Meniscus for Large Posterolateral Corner Loss Type of Discoid Lateral Meniscus

Large posterolateral corner loss type of discoid lateral meniscus tear is unsalvageable. Therefore, subtotal meniscectomy has been the only treatment option in this case. However, long-term results of subtotal or total meniscectomy have shown a high prevalence of early degenerative changes. Persistent symptoms, such as increased pain, snapping, giving way, locking, and limited extension, can be attributed to progressive loss of posterior tibial meniscal attachment and meniscal degeneration, especially in the posterior horn. The purpose of this technique-based article is to describe a partial repair, posterior horn repair augmented with the central portion of the discoid lateral meniscus that would have been removed if a subtotal meniscectomy were performed and bone marrow stimulation in the intercondylar notch to improve meniscal healing.
