Purpose: We compared the clinical and radiological results of meniscectomy with HTO or without HTO for degenerative medial meniscus posterior horn with varus deformity. Materials and Methods: Forty-two patients who had medial meniscus degenerative root tear with varus deformity more than 3 degrees were included for this study. Among them, 30 patients were performed meniscectomy combined with open wedge HTO and 12 patients were performed only meniscectomy without HTO. The mean follow-up period was 52.5 months. The clinical results were evaluated based on symptom improvement, patients' subjective satisfaction for surgery and HSS score. We also compared the osteoarthritic progression between the group on preoperative and at the final follow up radiographs. Results: Symptom improvement was achieved in 83.3% (25 cases) with HTO group and 66.7% (8 cases) without HTO group at final follow up with a significant difference. Patients' satisfaction was achieved in 83.3% (25 cases) with HTO group and 58.3% (7 cases) without HTO group which has a significant difference. The HSS score was improved in both group (90.8: with HTO group, 89.0: without HTO group) at the final follow up without significant difference. WOMAC score was improved in both groups at the final follow up without significant difference. There were no significant differences in the osteoarthritic progression between two groups. Conclusion: The good clinical result for treatment of patient who have medial meniscus degenerative root tear with varus deformity, proximal high tibial osteotomy is considered absolutely necessary. However, the progression of degenerative arthritis, its effect on long term follow up will be needed.

Although the lateral discoid meniscus of the knee has been observed frequently, the discoid medial meniscus has rarely been reported in the literature. A discoid medial meniscus with the horizontal tear and the peripheral tear of upper lip were observed. This tear pattern is not usual in the lateral discoid meniscus as well as in the normal meniscus. A plausible mechanism of the tear pattern compared with the normal shape and the discoid lateral meniscus was discussed in the following.

The incidence of septic arthritis after knee arthroscopy surgery has rarely been reported in approximately 0.04% to 3.4%. Moreover, septic arthritis after arthroscopic meniscal repair is more rare. There have been some reported cases, but in Korea, it has not been reported thus far. Herein, we report two cases of septic arthritis after arthroscopic meniscal repair with review of literature.

As arthroscopy is more advanced and the importance of meniscal function is more emphasized, there have been more advanced en meniscal repair technique. However conventional technique require the use of special instruments and extensive skin incision to protect the neurovasculatures and soft tissues. Also these have the potential problem of damage in articular surfaces by the knot. So, we develop a modified outside-in technique using spinal needles and nylon loops. Our method have many advantages not only in stability but simplicity, and there is no need of additional skin incision.

Purpose: The authors introduce a new technique of arthroscopic reduction of subluxed medial meniscus using suture anchor for the restoration of hoop stress. Operative Technique: Anterolateral, anteromedial, and medial midpatellar arthroscopic portal are used. Arthroscope was inserted through anterolateral portal. Through the scope, we confirmed subluxation of medial meniscus. Transection of menisci including radial and root tear were excluded. We released the anterior horn of medial meniscus through anteromedial and burred the future insertion site of suture anchor. After inserting suture anchor through medial midpatellar portal, we used 90 degree suture hook and no.2 Nylon to retrieve the suture of inserted anchor. We tied the suture by sliding knot-tying method. Weight bearing was limited for 6 weeks postoperatively. Conclusion: Arthroscopic retightening of medial meniscus is less invasive, conserving and progressed method for subluxed meniscus.

This study was undertaken to document the clinical results and technical aspects of arthroscopic repair including popliteus tendon as a post for the treatment of complex lateral meniscus in young people indicated as total meniscectomy. From June 2004 to May 2006, we prospectively studied arthroscopic repairs on 32 young people knees with symptomatic complex lateral meniscus that was treated by all inside repair technique using Popliteus tendon as a post. Clinical results were evaluated using Lysholm knee scores preoperatively and at final follow-up. 2nd look arthroscopy or MRI was taken at final follow-up. 80% of patients carried out MRI or 2nd look arthroscopy under permission. Most patients who follow up were able to return to their previous life activities with little or no limitation, and no reoperation was required after an average follow-up of 42.8 months. Mean Lysholm knee scores improved from 65.4 (range, 55 to 75) preoperatively to 93.9 (range, 79 to 100) at the final follow-up (P<.001). 80% meniscus healing was found on arthroscopic or MRI follow up. Conclusively, arthroscopic repair using Popliteus tendon as a post is effective for treating young people with complex lateral meniscus tear as a salvage procedure.

Purpose: To evaluate the effects of total or subtotal meniscectomy on anterior cruciate ligament reconstruction. Materials and Methods: We reviewed the 455 cases of arthroscopic ACLR (anterior cruciate ligament reconstruction) from February, 2003 to February, 2007 and followed-up more than 1 year. The 93 cases were enrolled. The 45 cases who underwent only ACLR were included and the 48 cases who underwent ACLR with total or subtotal meniscectomy were included in this study except grade 3 or 4 chondral lesion, partial meniscetomy or meniscal repair. We divided the patient into 4 groups which were isolated ACLR group (group I, 45cases), ACLR with lateral meniscectomy group (group II, 10cases), ACLR with medial meniscectomy group (group III, 28cases) and ACLR with both medial and lateral meniscectomy group (group IV, 10cases). The clinical evaluation was done by range of motion (ROM), IKDC subjective score, Lysholm score, anterior drawer test, Lachman test, Pivot shift test and KT-1000 arthrometer. Results: At final follow up, group IV was inferior than group I in IKDC subjective score and Lysholm score, and inferior than group II in IKDC subjective score. In KT-1000 arhtometric test, group I had better results than group III and group IV. Also in anterior drawer test and Lachman test, group 1 had better result than group III and group IV. In pivot shift test, there was no significant difference among four groups. Conclusion: Medial or both medial and lateral meniscectomy had greater laxity in anterior drawer test, Lachman test and KT-1000 arthrometric test and both medial and lateral meniscectomy had a lower subjective score than both meniscus intact group.

Purpose: The purpose of this study was to evaluate the factors affecting the treatment results of medial meniscus posterior horn tear. Materials and Methods: Forty seven patients who had been performed the arthroscopic surgery for medial meniscus posterior horn tear were enrolled in this study. We analyzed the clinical outcomes with Lysholm score and Tegner activity score in accordance with the factors such as patients' age, tibiofemoral angle, uptake in bone scintigraphy, surgical methods and patterns of meniscal tears, respectively. Results: The patients' age didn't affect to the results, but the preoperative tibiofemoral angle over valgus $4^{\circ}$ and the preoperative normal uptake in scintigraphic assessment showed a positive influence on the clinical outcomes. The partial meniscectomy and repair in surgical methods had no statistically significance. In addition, the pattern of meniscal tear did not have an effect on the clinical results. Conclusion: We can conclude that many factors should be considered to get satisfactory results. Among them, preoperative bone scintigraphy may be a good assessment factor for the postoperative prognosis, reflecting the condition of meniscal tear and the periarticular bone and soft tissue.

As awareness of root tear of meniscus have been increased, it became necessary to have an intensive repair. Posterior horn tear, especially for a lot of repair methods and the results have been reported recently. The report of the anterior root tear has yet to be found. We recently encountered a patient with an iatrogenic meniscal subluxation caused by past experienced partial menisectomy for discoid meniscus. Thus, we repots the technique and clinical results of arthroscopic repair of subluxated lateral meniscus anterior root tear using suture anchor.
