Abstract:
AIM:Discoid meniscus is named because its width and height are abnormally increased like a disc.In this study,we observed the injury classification and special features of discoid meniscus and natural meniscus,and compare the postoperative outcome of arthroscopy comparatively.METHODS:①360 cases of meniscus injury in knee joint were selected from the First Affiliated Hospital of Anhui Medical University from June 2001 to September 2006.They were divided into natural meniscus injury group(n =300),and discoid lateral meniscus injury(n =60).People with complete clinical data before operation and following data,confirmed by arthroscopy were selected.The written informed consent was obtained from them.②Meniscus injury in 360 cases was examined by arthroscopy,and plasty,or partial excision or incomplete resection or full resection was performed according to the injury types and surgical circumstance.③All subjects were followed for 6 months to 2 years.The knee function was evaluated by the criteria of Ikeuchi.RESULTS:300 cases of natural meniscus injury and 60 of discoid lateral meniscus injury were all included in the result analysis.①Five tear types of natural meniscus were as follows:43.7% longitudinal,30% radial,12.3% horizontal,7.5% transverse,and 6.5% complex.Four tear types of discoid meniscus were as follows:68.3% horizontal,6.7% radial,3.3% longitudinal,and 21.7% complex tear.②The surgical pattern was determined by the injury types,and all patients were followed up.In 300 cases of natural meniscus,there were 62 knees with excellent function,190 with good,34 with fair and 14 with poor.The excellent and good rate was 85%.In 60 cases of discoid meniscus,there were 19 knees with excellent function,34 with good,5 with fair and 2 with poor.The excellent and good rate was 90% approximately.CONCLUSION:Discoid meniscus is different in anatomical feature and histological structure from natural meniscus;therefore the arthroscopic surgery for discoid meniscus is also different.
