OBJECTIVETo study the clinical effects of menisci reformation and repair for the treatment of discoid meniscus injuries and to explore the operation methods.

METHODSFrom Jun. 2005 to Dem. 2009, 28 patients underwent arthroscopic menisci reformation and repair for discoid meniscus, including 23 males and 5 females, ranging in age from 6 to 42 years, with an average of 32 years. The nature of meniscus and the type and range of tear were judged under arthroscope. The menisci reformation and repair were used to treat discoid meniscus tear at the edge. After the operation, the brace was used for 8 weeks, and heavy exercise should be avoided for 6 months. The Lysholm score was adopted to evaluate therapeutic effects.

RESULTSAll the patients were followed up ranging from 3 to 36 months, averaged 8 months. The preoperative Lysholm scores ranged from 62 to 74, with a mean of (67.23 +/- 5.24), and the postoperative Lysholm scores ranged from 80 to 96, with a mean of (87.24 +/- 5.26). There was no occurrence of re-tear or re-operation due to symptom recurrence.

CONCLUSIONThe menisci reformation and repair has better clinical effects on the treatment of discoid meniscus tear and can be regarded as one of the operational options.
