RESUMO
Objective To analyze the therapeutic effect of arthroscopic meniscus -plasty in the treatment of meniscal lesions.Methods Patients admitted to our hospital′s department of orthopedics were reviewed,and they were divided into two groups according to the surgical methods.The observation group was treated with meniscus -plasty,while the control group was treated with meniscectomy.The Ikeuchievaluation standard was compared at the time of the last follow -up.The Lysholm and IKDC score were compared before and after treatment.Results The excellent -good rates were 86.5% in the observation group,which was significantly higher than that in the control group (62.8%,χ2 =5.768,P =0.016).There was no difference in Lysholm and IKDC score between the two groups before treatment[(63.4 ±10.8)points vs.(61.7 ±9.5 )points,P >0.05;(54.6 ±7.5 )points vs.(55.1 ± 8.3)points,P >0.05].After treatment,the Lysholm[(92.5 ±5.9)points and (90.4 ±6.6)points]and IKDC scores[(85.4 ±9.2)points and (83.6 ±9.8)points]were all significantly increased (t =14.383,16.269,15.784, 14.552,all P 0.05).At the time of the last follow-up,both Lysholm scores[(78.5 ±8.2)points]and IKDC scores[(75.5 ±7.9)points]were decreased in the control group (t =7.413,4.220,all P <0.05),and there were significant difference between the two groups (t =6.165,4.029,all P <0.05).Conclusion Meniscus -plasty and meniscectomy have similar short -term effects on meniscal lesions,but meniscus -plasty may show better effects in the long term.
RESUMO
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.
