“…Varus alignment, old age, high BMI, concomitant cartilage loss, and greater severity of joint degeneration have been documented as poor prognostic factors of partial meniscectomy in middle-aged or older patients242526). However, in younger patients, prognostic factors are not determined yet.…”

PurposeThe purpose of this study was to evaluate the demographics, clinical features, and outcomes of arthroscopic partial meniscectomy (APM) for isolated medial meniscus horizontal cleavage tears (MMHCTs) in patients under 45 years of age.Materials and MethodsWe retrospectively reviewed 98 patients (100 knees) under 45 years who underwent APM for MMHCTs. Clinical outcomes were assessed using International Knee Document Committee (IKDC) subjective core, Tegner activity scale, visual analog scale (VAS) pain score, and a question on the symptom relief.Results79% were male and 70% had no trauma. The mean symptom duration was 10 months. At arthroscopy, a flap tear was identified in 75%. At a mean of 19-month follow-up, the IKDC subjective score, Tegner activity scale, and VAS pain score were significantly improved compared to the preoperative values (p=0.025, p=0.043, and p=0.032, respectively). While 85% were free of symptoms, 15% had persistent pain. No significant differences in outcomes were observed based on the tear type and the presence of flap tears. No progression or development of radiographic degenerative changes was observed in all knees.ConclusionsDemographics of MMHCTs under age 45 showed a male dominance and higher frequency of non-traumatic tears. APM was beneficial to symptomatic HCTs in this cohort during the short-term follow-up. Type of HCTs and combined flap tears did not affect clinical outcomes.

“…Worse outcomes after meniscectomy are associated with 5 findings: greater severity of cartilage loss and bone marrow edema in the same compartment as the meniscus tear; greater severity of meniscus extrusion; greater overall severity of joint degeneration; a meniscus root tear; and a longer meniscus tear. 111 MR imaging findings Diagnosis of recurrent meniscus tears can be challenging, both by clinical evaluation and by MR imaging.…”

“…The consequences of a false positive finding are serious and can cause unnecessary arthroscopy or arthrotomy, which increases operation pains and economic burden for patients. Various possible complications could be generated because of unnecessary operations (De Smet and Tuite, 2006;Kijowski et al, 2011;Tokuda et al, 2012).…”

ABSTRACT. This study aimed to verify the accuracy of lowfield-intensity magnetic resonance imaging (MRI) in diagnosing meniscus tears. A total of 171 patients were examined through low-field-intensity MRI to detect meniscus injuries. These patients were then diagnosed through arthroscopy. Examination results were recorded and compared. The accuracy of the diagnosis for internal and external meniscus tears through low-field-intensity MRI was 95.91% and 95.91%, respectively, the sensitivities were 95.60% and 96.47%, respectively, and the specificities were 96.25% and 95.35%, respectively. Low-field-intensity MRI is an accurate and cost-effective method for diagnosing meniscus tears.
