Management of Horizontal Cleavage Meniscus Tears.

Abstract

Purpose of review: The management of horizontal cleavage meniscus tears (HCT) has evolved in recent years. Historically, HCTs have been treated with partial meniscectomy, but multiple studies have shown the long-term risks of development of arthritic changes in the knee following meniscectomy. These findings have renewed interest in meniscal preservation whenever possible, even in older patients not previously considered for meniscus repair. This article provides an overview of current management of horizontal cleavage meniscus tears and describes modern surgical techniques for repair of HCTs.

Recent findings: Current research studies have continued to emphasize the benefits of meniscal preservation on long-term function. Recent data has demonstrated similar success rates following repair of HCTs compared to repair of other types of meniscus tears. Additionally, multiple recent studies have demonstrated the potential benefit of biologic augmentation in decreasing failure rate after meniscal repair. Modern surgical techniques and biologic augmentation have improved outcomes of meniscal repair. However, consideration of a patient's individual goals, activity level, and expectation are important to achieve a successful outcome regardless of treatment modality. While not every patient is a candidate for meniscal repair, current data has shown it should be considered for a growing number of patients.
