“…Kaplan et al [11] suggested discoid lateral menisci develop due to abnormal motion caused by absence of posterior tibial attachment. Raheel [12] reported a case with familial discoid medial meniscus tear in 3 members of a family. We have reasons to believe that the discoid meniscus could be associated with genetic abnormality.…”

Rationale: Discoid meniscus is an anatomical congenital anomaly more often found in the lateral meniscus. A discoid medial meniscus is a very rare anomaly, and it is difficult to diagnose a bilateral discoid medial meniscus because not all the discoid medial menisci are symptomatic. Herein, we report 2 cases of bilateral discoid medial meniscus. Patients concerns: Case1: a 23-year-old man presented with complaints of pain and occasional clicking of the right knee for 6 years, the left knee was asymptomatic. Case 2: a 51-year-old woman had a 1-month history of pain and a feeling of “giving away” in both knees. Diagnoses: Based on physical examination and magnetic resonance imaging (MRI) findings, they were diagnosed with bilateral discoid medial meniscal tears. Interventions: Case 1: partial meniscectomy and reshaping were performed for the torn discoid medial meniscus of the right knee only. Case 2: partial medial meniscectomy and reshaping were performed for the torn discoid medial meniscus on both knees. Outcomes: The postoperative pain and the recovery of joint function were observed. The average follow-up time of 2 patients was 1 year. The Lysholm score of 2 patients was improved from 55 to 95 and 40 to 90 respectively. The pain of knee joint was relieved and the symptoms of disharmony were obviously improved. Lessons: We recommend preservation of the discoid medial meniscus in asymptomatic patients. Meniscectomy and reshaping for injured discoid medial meniscus produces promising short-term results.

“…The incidence rate for discoid lateral meniscus is reportedly 1.5%. [ 12 ] Discoid medial meniscus is rarer, with an estimated incidence of 0.12%, [ 1 ] and bilateral discoid medial menisci are rarer still. [ 2 ] The real incidence of discoid medial menisci is difficult to ascertain, as an unknown percentage of discoid menisci may be asymptomatic.…”

Rationale:Bilateral discoid medial menisci is an extremely rare abnormality of the knee joint. The presence of a discoid medial meniscus has been associated with magnetic resonance imaging (MRI) and radiographic changes in the tibial region, such as cupping of the medial tibial plateau and tibial physis collapse. While discoid medial meniscal tears with hypoplasia of the femoral medial condyles have not been previously reported. Herein, we report a case of bilateral discoid medial menisci associated with meniscal tears and femoral bone changes.Patient concerns:A 28-year-old man presented with left knee pain and restricted range of motion; the right knee was asymptomatic.Diagnoses:Based on radiographic and MRI findings, he was diagnosed with bilateral discoid medial meniscal tears.Interventions:Partial meniscectomy and reshaping were performed for the torn discoid medial meniscus of the left knee only.Outcomes:MRI revealed short, flattened femoral medial condyles in the coronal and sagittal planes, and hypoplasia of the femoral medial condyles in the axial plane; these findings were confirmed arthroscopically in the left knee. The patient had a satisfactory results at the 12-month follow-up.Lessons:This case indicates a potential link between discoid medial menisci and hypoplasia of the femoral medial condyle. We recommend preservation of the discoid medial meniscus in asymptomatic patients, while arthroscopic partial meniscectomy and reshaping is recommended in symptomatic patients.

“…He believed mechanical stress factors, such as excessive root activity behind the meniscus, gradually formed the discoid meniscus. Ahmed Ali[ 19 ] reported a familial case of medial discoid meniscus tear, suggesting that discoid meniscus may be associated with a genetic abnormality. Recent studies have shown that a discoid meniscus is abnormal in both morphology and histomorphology.…”

BACKGROUND Discoid meniscus is a congenital anomaly that typically affects the lateral meniscus. The appearance of the discoid medial meniscus in both knees is extremely rare, with an incidence of only 0.012%. CASE SUMMARY Our patient was a 30-year-old female. Under no obvious predisposing causes, she began to experience pain in both knees, which worsened while walking and squatting. The pain was aggravated after exercise, and joint flexion and extension activities were accompanied by knee snapping. Apley’s test was positive on physical examination, and there was a pressing pain in the medial articular space. Plain radiographs of both knees revealed no obvious abnormalities in the bilateral knee joint space. Partial meniscectomy as well as menisci reformation were performed on both knees under arthroscopy. Under the guidance of rehabilitation, the patient’s range of motion in both knees returned to normal without pain and knee snapping. CONCLUSION This study showed that the clinical manifestations of the discoid medial meniscus injury are identical to those of the conventional medial meniscus injury, and arthroscopic surgery is effective.
