Discoid Lateral Meniscus

AbstractThe anterior horn of lateral meniscus tear is usually repaired using outside-in technique. Although easy to perform, it was associated with several complications which may alter the outcome of the surgery. Here, we present a case of an adolescent girl presented with incomplete discoid lateral meniscus accompanied by tear of anterior horn. The tear was repaired using all-inside technique without any implants. We described the surgical technique and discussed the rationale.

The Stability

Introduction: Although uncommon, the discoid meniscus is quite prone to injury due to its abnormal shape and abnormal histology. The weak or absent peripheral attachment of the discoid meniscus causes instability even after partial meniscectomy. Therefore, recently, after resection of the central part of the meniscus, in which tears develop most frequently, the remnant of the meniscus is preferred to repair. In that time, the Watanabe classification, which classifies the discoid meniscuses in three groups, is used to plan treatment. However, discoid meniscus can develop in the different forms from these three main shapes. In the present study we aimed to analyse the discoid meniscuses, which we encountered during arthroscopic procedures in the knee, according to Watanabe classification. Patients and methods: The lateral discoid meniscuses in the 36 knees of 35 patients, who were operated on because of meniscus tear of either the discoid lateral meniscus itself or the normal medial meniscus, were classified according to Watanabe classification. Results: While the lateral discoid meniscuses were classified as “complete” in 13, “incomplete” in 15 knees, the meniscuses were very thin or absent in the central (one knee) or in the postero-lateral regions (seven knees) of discoid meniscus ( Figure 1 ). In this series this opening was next to the popliteus tendon except in one case. In these cases, the continuity of the meniscus between middle and posterior horn frequently was not possible after central partial meniscectomy (CPM). On the other hand, posterior horn has stable peripheral attachment unlike the Wrisberg type discoid meniscus. Of the 36 discoid meniscuses, CPM was performed in 21 knees, CPM with anterior horn repair in three, CPM with posterior horn repair in one and anterior horn repair without meniscectomy in two patients. In nine patients the lateral discoid meniscus was left alone. [Figure: see text] Discussion and conclusion: When meniscus sparing methods are intended to perform, both to decide the amount of resection and repair of the remnant, besides the shape of meniscus tear, the stability of discoid meniscus is crucial. This study shows that the Watanabe classification cannot be sufficient to include some specific type of lateral discoid meniscus. We believe that to add the discoid meniscuses, with opening in postero-lateral region next to the popliteus tendon, to the Watanabe classification might be useful to decide the amount of resection or repair of the discoid lateral meniscus.

Meniscus Surgery

Background: Discoid meniscus tear patterns vary, but typically involve horizontal cleavage tears of the central discoid component with or without anterior or posterior meniscocapsular tears. Classically, the central discoid component is saucerized and meniscocapsular tears are repaired. Recent data suggests that meniscal preservation provides long-term benefits over resection1-2. However, many meniscal transplants are performed secondary to unsalvaged or unsalvageable discoid meniscus tears3. Reoperation rates after meniscus repairs vary greatly4-6, with some series reporting high rates of reinjury and reoperation, but there are no large series of pediatric discoid meniscus repairs in the literature. The purpose of this study is to describe the outcomes of meniscus repair and saucerization in pediatric patients with symptomatic discoid menisci. Methods: A single-institution retrospective review was performed of consecutive pediatric patients with surgical treatment of a discoid meniscus tear over a five-year period. Inclusion criteria were age less than 18 years, a symptomatic torn discoid meniscus treated with knee arthroscopy with meniscus repair, and minimum 4-month follow-up. A chart review was performed to describe tear location, tear pattern, and repair type (inside-out, outside-in, all-inside, and hybrid). Hybrid repair constructs were defined as those that used 2 or more repair types. The primary outcome was revision meniscus surgery. Results: Forty-four patients were identified to meet inclusion criteria. There were 23 males and 21 females with a mean age of 12.4 years (range 5 – 17 years). The right knee was affected in 61% of patients. The lateral meniscus was involved in all patients. Tear patterns included anterior meniscocapsular (19 patients, 43%), posterior meniscocapsular (14 patients, 30%), radial (7 patients, 16%), and bucket-handle (5 patients, 11%). Tears most commonly involved the posterior horn and body (21 patients, 48%) or posterior horn (16 patients, 36%) Arthroscopic meniscus repair was performed in all patients. Forty-three patients (98%) also underwent saucerization. Marrow stimulation, as a biological approach to improve repair healing, was performed in 14 patients (32%). The distribution of repair types and number of sutures for each type is listed in the table below. Mean follow-up was 19 months (range 4 – 70 months). Four patients (9%) underwent revision meniscus surgery following the primary repair, including 2 all-inside repairs and 2 partial meniscectomies. There were no statistically significant differences between patients who did or did not require a secondary surgery with respect to sex, age, tear location, tear pattern, repair type, or number of sutures. During follow-up, 9 patients (20%) had surgery for a symptomatic discoid meniscus in the contralateral knee. Conclusions: Saucerization and repair of discoid lateral meniscus tears in the pediatric population have good outcomes with low rates of reoperation. Appropriate saucerization, followed by an arthroscopic assessment of stability and tear patterns is critical to successful treatment of symptomatic discoid menisci. If tissue quality permits, meniscal preservation should be considered in all patients to avoid the consequences of subtotal meniscectomy.
