Anomalous Insertion

Abstract Background Anatomical variations of the attachment of medial meniscus are a common finding. However, anomalies of the posterior horn are extremely rare. Only two cases of posterior root anomaly have been described prior to the routine use of arthroscopy for evaluation and treatment of meniscal pathology. In this report, we present an anomaly of both the anterior and posterior roots of the medial meniscus that posed both a diagnostic and therapeutic dilemma. Case presentation The patient is young male soccer player who is currently 16 years of age and began having the atraumatic onset of pain and symptoms that limited performance starting at age 14 and was referred for failure of response to nonoperative treatment. Diagnostic arthroscopy revealed the presence of an anteromedial meniscofemoral ligament whereas the posterior root showed no bony attachment. The radiographic and arthroscopic findings are described. The clinical decision was made after to proceed with observation, reassurance, and gradual return to full activity with physiotherapy guidance. Discussion and conclusion The absence of injury, the mild complaints reported by the patient, his age, skeletal immaturity, and remaining growth led us to adopt a conservative approach to treating this anatomic variant and currently the patient is able to participate fully in sports without symptoms or restrictions.

Discoid Medial Meniscus

Abstract Rationale: Complete discoid medial meniscus is an extremely rare abnormality of the knee joint whose meniscus has a discoid shape rather than a normal semilunar one. Several medial meniscus anomalies including anomalous insertion have been reported in the literature. This report presents a rare case of symptomatic complete discoid medial meniscus whose anterolateral (apical) portion was completely coalesced with the ACL. MRI, radiographic and arthroscopic findings in the medial compartment are to be submitted.Patient concerns and diagnoses: A 29-year-old male presented with intermittent pain and swelling of the right knee for 2 years. Based on radiographic, MRI and physical examination findings, he was diagnosed with discoid medial meniscus tears. Interventions and outcomes: Arthroscopic saucerization were performed for the torn discoid medial meniscus of the right knee. Arthroscopic examination revealed a complete discoid medial meniscus and the anterolateral (apical) portion of which was completely coalesced with the ACL. Careful Probing of the meniscal surface revealed there was a longitudinal tear extending from the tibial spine to the midportion of the meniscus. Arthroscopic saucerization of the discoid meniscus were performed After closely cutting the meniscus around the ACL. The patient reported a satisfactory results at the 12-month follow-up.Lessons: Complete discoid medial meniscus is an extremely rare abnormality, and this case presents the third complete discoid medial meniscus whose anterolateral (apical) portion was completely coalesced with the ACL. The current case we present strongly supports the theory that ACL and meniscus were differentiated from the same mesenchyme.

We report on the MR imaging of an anomalous medial meniscus with a tear in a 41-year-old man. Anomaly of the medial meniscus is rare and difficult to diagnose clinically. the MR images contributed to the pre-arthroscopic diagnosis and arthroscopy confirmed the lesion. the anomalous meniscus was not related to the symptoms
