Midterm follow-up of symptomatic discoid meniscus after arthroscopic surgery / 第三军医大学学报

ABSTRACT

Objective To evaluate the effect of arthroscopic reshaping procedures on symptomatic discoid meniscus and compare the outcomes between children and adults. Methods The medical records of those who had undergone arthroscopic reshaping procedures for symptomatic discoid meniscus between January 1997 to December 2000 were reviewed. Results Fifty-four patients had been followed up more than 7 years, including 38 children and 16 adults. The average Lysholm score increased from (65.0?10.0) preoperatively to (72.0?10.0) postoperatively. The average 8.2-year follow-up showed no obvious clinical symptoms and signs or osteoarthritis in children. Fourteen knees in adults were found osteoarthritis on X-ray film, of which 6 showed the symptoms and signs of osteoarthritis. Conclusion The midterm efficacy of arthroscopic surgery for symptomatic discoid menisci and the occurrence of postoperative osteoarthritis are related to age and injury course.
