Abstract

PURPOSE: To evaluate the clinical results of preserving the peripheral rim of meniscus in the injuries of lateral discoid meniscus.
MATERIALS AND METHODS
We analyzed 38 patients, 40 knees. Mean follow-up period was 17.4 months and mean age was 34.9 years old(10~62). We classified the lesion according to Watanabe and Ahn(classifying the type of tear according to arthroscopic finding). Clinical results were analyzed by Ikeuchi's clinical grading system and the Lysholm knee scoring scale. Radiographic evaluations were analyzed with plain radiographs. The common clinical results were pain in 40 cases(100%), locking in 16. Radiological degenerative arthritis changes were 31 persons(33 cases, 82.5 %) by simple initial X-ray. The common radiological changes were hypoplasia of lateral femoral condyle in 29 cases (72.5%), widening of lateral joint space in 26.
RESULTS
Partial meniscectomy was undergone in 14 patients(15 cases) and partial meniscectomy with meniscal repair was undergone in 24 patients(25 cases). The patients were categorized using Watanabe's classification: complete, 25 cases(62.5%) and incomplete, 15 cases(37.5%). There were longitudinal tears(type 2) in 15 cases(37.5%), complex tears(type 7) in 12 cases. The mean Lysholm score was improved from 56.7 points to 86 points postoperatively after the partial meniscectomy, and from 62.7 points to 88 points after the partial menisccectomy with meniscal repair, which were not statistically significant(p>0.05). According to Ikeuchi's grading system, 11 cases(73.3%) had either excellent or good ratings in the partial menisectomy and 21 cases(84%) in the partial menisectomy with meniscal repair, which were not statistically significant(p>0.05).
CONCLUSION
We believe that preserving peripheral meniscus by using partial menisectomy and partial menisectomy with meniscus repair lead to good function and satisfactory results.
