Abstract

The aim of the study was to characterize under arthroscopy the features of normal and discoid meniscus injury, and to access the efficiency of recovery after operation. Data from 200 patients with meniscus injury who were admitted between May 2011 and October 2013 were collected. According to the type of meniscus injury, patients were divided into two groups: normal meniscus injury group (100 patients) and discoid meniscus injury group (100 patients). Types of operation and characteristics of joint injury were compared between groups. Further, we compared recovery rates at 1-year postoperative follow-up, using Coriolis knee evaluation of joint functions. We observed five types meniscus tear in patients with normal meniscus: 40 % longitudinal, 32 % radial, 13 % horizontal, 8 % transverse, and 7 % complex. In discoid injury, these were, respectively, 5, 3, 75, 7, and 10 %. Longitudinal, radial, and horizontal injury rates were significantly (p < 0.05) different between both groups. During operation, total, subtotal, and partial resections were utilized for normal meniscus injury in 10, 27, 63 % of cases, and for discoid meniscus injury in 60, 25, and 15 %. Total resection was used significantly more frequently (p < 0.05) in discoid meniscus injury. A postoperative follow-up 1 year later revealed that the rates of excellent, good, and poor recovery were comparable between both normal and discoid meniscus injuries. With more frequent total resection for discoid meniscus injury and patients protecting their knee joints after the operation, the recovery rates are comparable between patients with normal or discoid meniscus injury.
