Arthroscopic Reshaping of Discoid Meniscus with Local Anaesthesia and Radiofrequency

Objective To study the effect of arthroscopic plasty of discoid meniscus with local anaesthesia and radiofrequency. Methods From Aug. 2000 to Aug.2002, arthroscopic plasty of discoid lateral meniscus with local anaesthesia and radiofrequency was performed on twenty-six joints in twenty-three patients including 12 male and 11 female, their average age was 25 years(13～14 yrs). The procedure of discoid meniscus reshaping in 23 cases was to produce the similar appearance to the normal lateral meniscus. Unstable leaf of the horizontally torn meniscus was removed, while the stable one was preserved. In 6 cases,the tear of edge rim was not only reshaped but also insider-out sutured. Results 21 cases were followed-up for average 11 months (from 5 months to 2 5 years).There was no pain snap and lock, the joint function is normal in 21 cases and 23 knees. Based on Ikeuch knee functional scales,16 cases were rated as excellent, 3 good and 2 fair. Conclusion Arthroscopic radiofrequency meniscus plasty is of importance in avoiding total meniscectomy. The procedures were safety and less traumatic.
