Purpose : To introduce arthroscopic partial meniscectomy fur bucket handle tear of medial meniscus using posteromedial portal, which is superior to arthroscopic partial meniscectomy using standard anterior portals commonly used. Method : After arthroscopic examination of the knee, we reduce the torn meniscus, advance the arthroscope into posteromedial compartment under arthroscopic visualization, we make posteromedial portal with reexamination of the compartment and perform arthroscopic partial meniscectomy. Conclusion : With the technique of arthroscopic partial meniscectomy using standard anterior portals, accurate partial meniscectomy can not be done because of inadequate visual field, associated meniscal injuries of posterior horn and cartilage lesion of posterior aspect of the medial femoral condyle can be missed, commonly posterior cruciate ligament can be injured and artificial damage to weight bearing surface of medial femoral condyle is possible. An arthroscopic partial meniscectomy using posteromedial portal is an excellent method fur bucket handle tear of medial meniscus.

Recent studies suggest that most meniscal cysts can be treated surgically by arthroscopic management of the meniscal tear and arthroscopic cyst evacuation. But arthroscopic cyst decompression may sacrifice a substantial amount of meniscal tissue that is not torn in order to expose the "stalk" of the cyst. Nowadays, the trend is changing as preserving the involved meniscus to prevent from inevitable degenerative changes after meniscectomy. The purpose of this report is to describe a new surgical technique that minimizes loss of meniscal tissue in hopes of maximizing residual meniscal function. We experienced 10 patients with meniscal cysts that were consisted of four lateral cysts and six medial cysts. Menisci were torn in all cases. Arthroscopic partial meniscectomy and decompression of cysts were performed in 9 cases, and arthroscopic partial meniscectomy and open cystectomy in 1 case. The procedures were consisted of injection of the methylene blue into the cyst, partial meniscectomy of the meniscal tear until the dye was seen in orifice of the cyst, and decompression of cyst through cystic opening. This article serves to confirm the relationship between torn menisci and cysts, to re-evaluate the occurrence ratio of the meniscal cyst on the medial to lateral meniscus, and to assess the efficacy of arthroscopic partial meniscectomy and decompression of cyst as a potentially meniscal sparing procedure.

Discoid meniscus is an uncommon cause of internal derangement of the knee joint. The discoid medial meniscus is much less common than the discoid lateral meniscus. A 15-year-old male student had a incomplete discoid medial meniscus of right knee combined with a horizontal tear. This was confirmed by magnetic resonance imaging(MRI) and arthroscopic procedure. Partial meniscectomy was performed arthroscopically. An unevenful recovery followed. We report a case of discoid medial meniscus with brief review of literature.

Purpose : After the total or partial meniscectomy of the lateral discoid meniscus, many patients complain the residual pain or the recurrent symptoms of the meniscus, and some of them need reoperation. We analyzed the causes of the reoperation after initial meniscectomy. Material & Method : Two hundred seventy three patients with the symptomatic lateral discoid meniscus were treated by arthroscopic meniscectomy between October, 1989 and September, 1998. Of the 273 patients, 69 patients were treated by total meniscectomy and 204 patients were treated by partial meniscectomy. The male to female sex ratio was 1:1.04, and the average of the age was 23.1 years old(from 4 to 59 years old). The reoperation was done in 8 patients, of which 1 was the case of total meniscectomy at the initial operation, and the rest 7 were the case of partial meniscectomy. Results : Of the 8 reoperations, 3 patients recurred the meniscal symptoms within the 3rd week after the initial operation, and 5 patients recurred beyond the 3rd week after the initial operation. Among the 3 patients of carly recurrence, 2 patients showed inadequate sizes of the remnant meniscus, and 1 patient showed posterolateral instability of the remained meniscus. Among the 5 patients of late recurrence, 3 patients showed rerupture of the meniscus, and 2 patients showed associated pathology of degenerative arthritis following osteochondritis dissecans. Conclusions : The reoperation rate after initial meniscectomy of the lateral discoid meniscus was higher in partial meniscectomy than total meniscectomy. During the operation of the lateral discoid meniscus, we must determine the adequate resectional margin, confirm the remnant meniscus by probing, and look for the associated pathologies.

Purpose: To evaluate the results of meniscal repair and partial meniscectomy of lateral meniscus injury associated with tibial plateau fracture. Materials and Methods: Between February 1993 and August 2004, 24 cases (23 patients) of lateral meniscus tear with tibial plateau fracture were evaluated retrospectively. The most frequent type of tear was the longitudinal tear of the meniscocapsular junction (14 cases, 66.7%). All fractures were reduced under the control of arthroscopic and image intensifier. Arthroscopic repair of the longitudinal tear of the lateral meniscus or arthroscopic partial meniscectomy was performed. The final results were evaluated with the Ikeuchi criteria and Lysholm score. Results: At the final follow-up, the outcome was excellent in 12 cases (85.7%), good in 1 case (7.1%) and fair in 1 case (7.1%) among 14 cases of meniscal repair, and the excellent in 4 cases (66.7%) and good in 2 cases (33.3%) among 6 cases of partial meniscectomy according to the Ikeuchi criteria, There was a significant improvement of Lysholm score after surgery, 92.3 postoperatively compared with 56.6 preoperatively (p<0.0001, paired t-test). Conclusion: The fracture of the lateral tibial plateau did not seem to affect on the healing of the meniscus repair and partial meniscectomy.

Purpose: To study the long-term outcome of arthroscopic meniscectomy with regard to clinical symptoms and radiographic signs of osteoarthritic change. Materials and Methods: The materials for the investigation consisted of 79 individuals among 144 patients who underwent knee arthroscopy due to an isolated meniscal tear from October 1990 to September 1992 in our hospital. Those 79 individuals were followed up for $10{\sim}15$ years after the knee arthroscopy and were took clinical examination through the review of knee radiographies obtained with weight bearing. 52 of the 79 patients were men, and the mean age of the total materials was 34.6 years old (in the range $17{\sim}48$). Results: At follow-up, radiographic changes including Fairbank changes and joint space narrowing were seen from 45 of the 79 patients (56.2%). In other calculation, radiographic changes were seen in 23 out of 54 patients (42.6%) who had a partial meniscectomy, but were presented in 22 out of 25 patients (88.0%) who had a total meniscectomy. As a result, more radiographic changes were seen after total meniscectomy (p=0.03). In clinical results, 39 out of 54 patients (72.2%) after partial meniscectomy were satisfactory, and 14 out of 25 patients (56.0%) after total meniscectomy were satisfactory, therefore, more percentage of patients were satisfactory in partial meniscectomy group than in total meniscectomy group, but the statistical differences were absent (p=0.24). Conclusion: The frequency of radiographic changes in $10{\sim}15$ years after meniscectomy was related to the quantity of the meniscus removed, but the differences of these changes were low and had little influence on activity and knee function.

Several reports have described the increased perioperative risks as well as surgical techniques for performing various procedures in obese patients. However, few reports have addressed the effects of obesity on routine arthroscopic procedures known to be common and safe. Describing the case of a partial meniscectomy performed in a 17-year-old male with a body weight of 120 kg, we review literatures published to the present and provide technical problems and possible complications that can occur when performing routine knee arthroscopy in bariatric patients.

Purpose: In patients with meniscal tear with degenerative arthritis, controversy remains as to whether arthroscopic menisectomy is worthwhile or not. The purpose of this study was to evaluate the effect of arthroscopic medial meniscectomy in degenerative arthritis of the knee with meniscal tear. We also intended to identify pertinent indications and risk factors. Materials and Methods: 287 patients underwent arthroscopic medial meniscectomy from 2006 to 2008; 103 patients who had Kellgren-Lawrence grade II, III arthritis of the knee, were over 50 years old, and had minimum 1 year follow-up, were analyzed in this study. Clinical assessment was performed retrospectively using the arthroscopic surgery database, medical records, questionnires and interviews. Assessment included visual analogue scale (VAS) scores and Lysholm scores. Results: The mean Lysholm score increased from 69 to 85 after surgery. The mean VAS score improved from 7 to 3.1 after surgery. Kellgren-Lawrence grade II group and group with trauma history showed significant improvement of pain and function compared with grade III and group without trauma history. Outerbridge grade I showed significantly more improvement of pain than grade III and IV. Multiple regression analysis showed that trauma history and Outerbridge grade affect the improvement of Lysholm score. Conclusion: In one year follow-up, arthroscopic medial menisectomy can improve pain and function of patients in Kellgren-Lawrence grade II, III degenerative arthritis of the knee. We could expect good results especially in group with low Kellgren-Lawrence grade, trauma history, and mild articular cartilage lesion.
