PURPOSE: The purpose of this study was to describe the clinical outcomes of partial meniscectomy in @entity1 with "fatigue @entity937 ", which presents as a non-traumatic tear with abrupt onset of symptoms of a radial tear in the transition between the middle and posterior thirds of the meniscus. METHODS: We prospectively followed 71 @entity1 with "fatigue @entity937 " (41 @entity1 and 30 @entity1 , mean age of 63  years, SD 6.9  years) recruited among 497 @entity1 with isolated medial meniscal lesions treated between January 2006 and June 2011. Inclusion criteria were spontaneous abrupt onset knee @entity158 , minor or no @entity130 , no radiographic or MRI @entity571 , no bone @entity4 , pre-operative magnetic resonance image of medial meniscus tear, and arthroscopic evaluation demonstrating radial or vertical flap tear in the body to posterior horn junction of the medial meniscus. We followed all @entity1 for a minimum of two years and reviewed their clinical symptoms, physical exam, functional outcome, and @entity1 satisfaction at last follow-up. RESULTS: The average follow-up was 4.2  years, with a minimum follow-up of two years. Among the 71 @entity1 , there were 59 (83.1  %) good or excellent results and 12 (16.9  %) poor results. These 12 @entity1 demanded further treatment because of persistent @entity158 , with three of the @entity1 developing @entity174 . All @entity1 complaints and poor outcomes could be identified in the initial six months after surgery. There was no gender difference in the subgroup analysis. CONCLUSION: Our findings indicate that @entity1 with "fatigue @entity937 " benefit from arthroscopic partial meniscectomy, with only 16.9  % reporting unfavourable results. LEVEL OF EVIDENCE: IV, Cohort study or case series.
