  • Purpose: The purpose of this study was to compare the preoperative magnetic resonance image (MRI) findings with postoperative arthroscopic findings on meniscus injury with anterior cruciate ligament (ACL) rupture. Materials and Methods: We reviewed MRI images and arthroscopic findings of 225 patients treated by ACL reconstruction due to rupture, from February 2001 to November 2010. There were 154 cases of meniscus tear in arthroscopic findings. We examined the sensitivity for detecting meniscal tears varied with the presence of a rupture of the ACL, with the location of the tear within the meniscus, and among configurations of meniscal tears. Results: In the presence of a rupture of the ACL, the sensitivity of MRI was 0.88 for medial meniscal tears and 0.69 for lateral meniscal tears. And sensitivity of MRI was lowest in posterior horn and peripheral portion tears in lateral meniscus injury accompanying ACL rupture, sensitivity was low in anterior horn and flap shape tears in medial meniscus injury accompanying ACL rupture. Conclusion: In Meniscus injury with ACL rupture, a special attention shoulder given to the posterior horn and peripheral portion injury in lateral meniscus during arthroscopic surgery due to difficulty in detecting on MRI.

  • Purpose: We report mid to long - term results of meniscal transplantation and evaluate the important factors for successful outcomes. Materials and Methods: Between December 1999 and September 2002, 25 meniscal transplantations were performed using fresh frozen allograft. The lateral meniscus was transplanted in 19 cases and medial meniscus in 6 cases. The mean age was 34 years (range, 17~50 years) and the mean follow up was 54.8 months (range, 6~85 months). Preoperative measurements were made using a ruler graded in millimeters. Lateral meniscus was fixed by keyhole technique and medial meniscus was fixed by double bone plug technique with suturing the periphery of the meniscal transplant. All patients were evaluated with Knee Assessment Scoring System (KASS), Lysholm knee score, and Tegner activity scale for daily activity. Results: Symptoms improved in all cases. The average KASS score increased from 61.7 preoperatively to 83.8 postoperatively. The average Lysholm knee score increased from 77.7 preoperatively to 87.7 postoperatively (excellent in 3 cases, good in 17 cases, fair 4 cases, poor 1 case). But painful swellings were 3 cases, numbness in 1 case, and granuloma due to non-absorbable suture material in 1 case. Peroneal nerve palsy in 1 case was recovered after 6 weeks postoperatively. Conclusion: Meniscal allograft transplantation after subtotal or total menisectomy can significantly relieve pain and improve function of the knee joint. The exact preoperative sizing and secure fixation are essential for successful outcomes.

  • 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.

  • Treatment options are limited for young, meniscal-deficient patients with pain. This patient population is not age appropriate for total joint replacement, but the loss of the meniscus leaves them at significant risk for the development of osteoarthritis. One increasingly popular option is the use of allograft meniscal transplantation. However, many questions still surround allograft meniscus transplantation. Furthermore, most reports in the literature on the results of meniscal transplantation describe small case series using clinical outcome measures and/or incomplete direct evaluation of the meniscus. Therefore, the results of meniscal allograft transplantation have been difficult to interpret and compare due to many confounding variables. In this study, we reviewed the current research of concerns on the results of meniscal allograft transplantation.

  • 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.

  • 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: 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.

  • 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.
