Purpose: This study is to evaluate the clinical findings of media] meniscus root tear, pull-out repair technique and it's short term results. Materials and Methods: From September 2003 to August 2004, 23 cases of total 27 medial meniscus root tears were treated by pull-out repair technique. Mean age was 60.2 years old. The pull-out technique was divided into 2 groups In group 1(14/23 cases), anterolateral portal was used and in group 2(9/23 cases), anterolateral and posteromedial portals were used for bed preparation. Concomitant cartilage lesions were documented as ICRS mapping system. The clinical outcomes were evaluated according to Lysholm Knee Score. Results: The postoperative Lysholm Knee Score was 77.1(range; $58{\sim}97$) in group 1 and 81.4(range; $72{\sim}94$) (p>0.05). The failure rate was 3 of 14 cases(21.4%) in group 1 and 1 of 9 cases(11.1%) in group 2. Twenty of 22 cases(90.9%) showed cartilage lesions in weight bearing portion of medial femoral condyle which were 8 grade III and 5 grade IV according to the Outerbridge classification. Conclusion: Pull-out repair seems to be a useful treatment of the medial meniscus root tear for preservation of circumferential hoop tension of meniscus.

Flap tear is a type of displaced meniscal fragments that is often clinically significant lesions requiring surgical intervention. If the displaced tear is located inferomedial to the tibial plateau and incarcerated into the articular capsule, it can be overlooked from preoperative magnetic resonance imaging evaluation and escape detection during arthroscopic examination. In addition, the clinical feature and treatment result of incarcerated flap tear has not been reported. We present 2 cases of medial meniscus flap tear incarcerated into the articular capsule that showed specific clinical features, in order to emphasize the importance of clinical suspicion of such a lesion for accurate preoperative diagnosis.

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.

Purpose: The purpose of this study was to evaluate the results of treatment for longitudinal meniscal tear in ACL rupture patients by clinical evaluation and $2^{nd}$ look arthroscopy. Materials and Methods: Among the patients who underwent surgery due to ACL rupture and longitudinal meniscal tear between 2002~2009, 32 patients were selected for the study. The patients were devided into three groups; group 1 had repair, group 2 had partial menisectomy due to impossible to repair, group 3 had conservative treatment due to stable meniscus. Comparative retrospective analysis was applied with KT 1000 arthrometer, Lysolm' score, Tegner activity score, IKDC subjective score, and $2^{nd}$ look arthroscopy. Results: Lysolm' score, Tegner activity score, IKDC subjective score showed no statistical difference in all three groups. KT-1000 side to side difference improved from 6.2, 6.15, 6.38 before surgery to 2.56, 2.49, 2.58 after surgery in group 1, 2, and 3, respectively. In group 1, second-look arthroscopy revealed complete healing in 12 patients, incomplete healing without any clinical symptoms in 2, and healing failure in 1. In group 2, second-look arthroscopy showed partial regeneration on margin of meniscectomy. In group 3, second-look arthroscopy revealed complete healing in 2 patients, while 4 showed incomplete healing so that have repaired. Conclusion: In the study, the outcome was better when the stable longitudinal meniscal tear on posterior horn with ACL rupture had active treatment.

Purpose : The purpose of this study was to evaluate the clinical results of meniscal repair using the bioabsorbable devices. Materials and Methods : From 1998, 21 meniscal repairs were underwent using the bioabsorbable devices and followed more than 1 year. The Meniscus $Arrow^{\circledR}$(Bionx) and the Meniscal $Fastener^{\circledR}$(Mitek) had been applied. The indication for meniscus refixation was an unstable longitudinal tear in the posterior horn of the medial or lateral meniscus. Concurrent ACL reconstruction with meniscal repair was performed on 9 knees. The clinical result was evaluated using Lysholm knee score. Result : The average Lysholm knee scores for all patients improved from 56 preoperatively, to 89 postoperatively. The type of the device were not significantly related to clinical outcome or Lysholm knee score. But the concurrent ACL reconstruction group and the patients treated within 8 weeks had better clinical result than the others. Conclusion : The all-inside meniscal repair technique using bioabsorbable devices can be considered to be an useful method in the well selected patients and concurrent ACL reconstruction surgery.

Purpose: To examine the clinical results after arthroscopic meniscectomy of radial tear of medial meniscus. Materials and Methods: We studied 45 cases with the radial tear of medial meniscus which follow up more than 2 years(range 2 to 7 years). Arthroscopic surgery was performed to the patients with grade 0-2 according to the Kellgren and Lawrence classification. Evaluation of cartilage damage was performed on surgical photos according to Outerbridge classification. Evaluation of clinical result was used the modified Lysholm score. Results: The mean pre-operation Lysholm score was 79.1, 71.2, 68.5, 67.9, 67.2, 61.5 and post-operation Lysholm score was 86.3, 75.1, 73.0, 73.1, 73.2, 66.2 and 61.5%, 62.5%, 60.0%, 50.0%, 50.0%, 25.0% improved knee pain and 69.2%, 75.5%, 70.0%, 66.6%, 75.0%, 75.0% were satisfied knee surgery and 30.7%, 20.5%, 20.0%, 50.0%, 25.0%, 50.0% required further surgery in patients respectively. According to Kellgren and Lawrence classification, 7 cases(15.5%) progress grade 3 osteoarthritis. Conclusions: The radial tear of medial meniscus showed the poor results with arthroscopic meniscectomy even if the grade 0-2 osteoarthritis. For the improvement of the clinical results, consider the technique to restore the hoop stresses or use the high tibia osteotomy for preventing the osteoarthritis.

Purpose: This study is to evaluate the clinical results of pull-out suture for root tear of posterior horn of medial meniscus. Materials and Methods: Between March 2006 and February 2011, We studied 40 cases with the root tear of posterior horn of medial meniscus which follow up more than 1 years. Mean age was 49.5 years old. We excluded osteoarthritis or varus deformity patients more than 5 degrees. pull-out suture was performed to the patients with grade 0-2 of Kellgren and Lawrence classification. According to Outerbridge classification, evaluation of cartilage damage was performed during arthroscopy. Evaluation of clinical result was used the Lysholm score. Results: The mean pre-operation Lysholm score was 63.9 and post-operation score was 86.3. The complete failure rate was 3 of 40 cases (7.5%). Twenty of 40 cases (50%) showed cartilage lesions in weight bearing portion of medial femoral condyle which were 12 cases in grade 1, 5 cases in grade 2 and 3 cases in grade 3 according to the Outerbridge classification. Conclusion: In the treatment of pull-out suture for root tear of posterior horn of medial meniscus, exclusion of more than moderate arthritis or varus deformity is very importment. Pull-out suture seems to be a useful treatment of the root tear of posterior horn of medial meniscus in mild osteoarthritis or varus deformity of middle ages.
