Purpose : To evaluate tile clinical results of resorbable meniscal arrow fixation for repairable meniscal tear with concurrent anterior cruciate ligament(ACL) reconstruction. Materials and Methods : Between April, 1997 and June, 1999, we performed resorbable meniscal arrow fixation and ACL reconstruction simultaneously for 18 cases of repairable meniscal tears with ACL injuries. Nine cases were acute injuries, 5 cases, subacute and 4 cases, chronic. The average follow-up was 21.5 months($12\~38$ months). Results : The healing rate was $89\%$ for acute injuries, $80\%$ for subacute injuries and $50\%$ for chronic injuries. Conclusion : Resorbable meniscal arrow fixation with concurrent ACL reconstruction is a good treatment modality for acute and subacute injuries.

Purpose : To evaluate the results and usefulness of meniscal repair using meniscal arrows with ACL reconstruction. Material and Methods : Among cases of the simultaneous meniscal arrow fixation and ACL recontruction performed between May, 1997 and September, 2000, 17 cases could be evaluated. The average follow-up were 18.5 months. Twelve cases were medial meniscus, 5 cases, lateral meniscus. All cases were longitudinal tear. Meniscal tear were seen at red-red zone in 13 cases, red-white zone in 5 cases. The results were analyzed by pain, joint line tenderness, locking, McMurray test, the Marshall knee scoring scale and complications. Results : Postoperatively two patients had mild joint line tenderness without pain on joint motion or weight bearing. No patient had locking or positive McMurray test. At last follow-up, 15 cases $(88\%)$ were 'excellent' or 'good' according to the Marshall knee score scale. There were two complications which are soft tissue irritation sign on active knee motion and a femoral chondral injury due to protruded T-shaped head of meniscus arrow. Conclusion : Meniscus arrow can be one of the options in repairing the associated meniscus tear, especially the posterior horn of medial meniscus, during ACL reconstruction. However, surgeons using meniscus arrow should be aware of its potential complications such as pain due to soft tissue irritation and chondral damage of the femoral condyle.

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.

In the diagnosis of the meniscal tear of the knee, the high accuracy of the MRI diagnosis is well-known, but the accuracy of the MRI in the diagnosis of the very pattern of the tear of menisci is not well-established. The purpose of this study is to give some informations to consider in the diagnosis and therapeutic planning of torn menisci. The authors performed a retrospective study comparing the MRI and arthroscopic findings of 141 knees which had undergone arthroscopic surgery from Mar. 1997 to Mar. 1998. The results are as follows. In the diagnosis of tear of the menisci, MRI had sensitivity of 91%, specificity of 96%, accuracy of 95%. The mismatch of the tear patterns of the menisci between MRI and arthroscopic findings was identified in 59%, especially high in flap tear(100%), complex tear(84%), peripheral tear(55%). In conclusion, MRI is very accurate in the diagnosis of the tear of menisci, but the tear patterns of the menisci cannot be accurately determined by MRI. In the cases of flap tears, complex tears and peripheral tears, it is more difficult to determine the tear patterns of the menisci by MRI. False-negative rate of MRI was especially high(44%) in the peripheral tear type. So, other clinical correlations should be made in determination of the presence of the tear in the diagnosis of peripheral tear of the menisci.

Purpose : The purpose of this study is to compare with result of repair and resection in displaced bucket handle medial meniscal tear. Materials and Methods : From Sep. 1998 to Dec. 2001, we experienced 46 cases, 45 patients. We classified them into repair group (group I, 23 cases) and resection group (group II, 23 cases). We analyzed the time interval between injury and operation, zone of tear, the status of reduction and quality of displaced fragment of all cases. Average follow-up period is 29, 28 months, respectively. We evaluated the final results of both groups as Lysholm knee score, radiologic changes and 2nd look arthroscopy. Results : Mean age was 25 years old in both group, respectively. Mean interval between injury and surgical treatment was 12 and 17 weeks. respectively. In group I, 6 of 7 cases were evaluated as clinical success in red-red zone, 12 of 15 cases were assessed as clinical success in red-white zonal tear, stable reduction. Another case which is evaluated as clinical failure showed red-white zonal tear, unstable reduction and poor quality meniscal fragment. 5 cases showed variant degrees of tibio-femoral compartment symptom. In group II, red-white zone (9 cases) and white-white zone (14 cases) were treated as resection and got good results. Conclusion : Considering zone of tear, reducibility and quality of meniscal fragment before treatment will improve the success rate of meniscal repair.

A new method for arthroscopic resection of the inferior leaf for the horizontal tear in the anterior horn of the meniscus extending deep toward the capsule was developed. Resection of this tear is difficult-perhaps more so than any other meniscal tear. At arthroscopy, a small incision on the meniscotibial ligament of the anterior horn was made after the deep horizontal tear was carefully debrided. A retrograde punch was introduced through the incision and underneath the inferior leaf of the anterior meniscus. The inferior leaf of the anterior horn was resected by the punch without difficulty. This simple technique minimizes the risk of superior leaf injury and can be used for a horizontal tear in the anterior horn as well as the mid horn with sweeping motion of the retrograde punch.

The purpose of this study is to report the effectiveness of complex Korean Medicine treatment for anterior cruciate ligament (ACL) injuries with meniscus tear. Four patients were treated with complex Korean Medicine by acupuncture, pharmacopuncture and herbal medication. We evaluated the improvement of knee pain and function by Numeric Rating Scale (NRS), Western Ontario and McMaster Universities Arthritis Index (WOMAC Index), EuroQol-5 Dimension Index (EQ-5D Index). After treatment, we found that knee pain was reduced and joint function was improved by NRS and WOMAC index in all cases. In the evaluation of health-related quality of life through EQ-5D index, there was no significant difference in patients with degenerative knee osteoarthritis and severe meniscal injury. This results show that complex Korean Medicine may be an effective option for ACL injuries with meniscus tear. Further clinical studies are needed to clarify the effect of Korean Medicine therapy on ACL injuries with meniscus tear.

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.
