  • Purpose : The purpose of this study was to investigate the incidence, location, type and treatment of meniscal injury associated with acute anterior cruciate ligament (ACL) tears Material and Methods: From Mar. 1997 to Feb. 2002, we reviewed 73 cases of acute ACL tear. There were 66 males and 7 females. The average age at the time of surgery was 33 year old (range, 16-62 years). The common causes of meniscal injury were sports injuries (45 cases) and traffic accidents (19 cases). In 45 sports injuries, thirty four cases were soccer injuries. All patients had undergone arthroscopic evaluation. We analyzed incidence, type, location, and treatment of meniscal injuries, especially those of soccer injuries. Results : Foully eight (57 sites) out of 73 had meniscal tears : Of these injuries, tears of lateral meniscus (26 cases, $54.2\%$) were more common than medial meniscus. Posterior horn of the meniscus was the most common location (52 cases, $91.2\%$) and radial tears were the most common type (15 cases, $26.3\%$). Thirty eight cases $(66.7\%)$ were treated by partial menisectomy. In soccer injuries, twenty eight (33 sites) out of 34 had meniscal tears. and tears of lateral meniscus (17 cases, $60.7\%$) were more common. Posterior horn of the meniscus was the most common location (30 cases, $90.9\%$) and radial tears were the most common type (9 cases, $27.3\%$). Twenty two cases $(66.7\%)$ were treated by partial menisectomy. Conclusions : Lateral meniscal tears in the setting of an acute ACL insufficiency are more common than medial meniscal tears. The findings in the this study would be helpful in clinical diagnosis and subsequent treatment decisions in patients with an acute ACL tears.

  • Injuries to the menisci occur in a variety of ways, most commonly with a twist, pivot, squat, or valgus stress to the knee. Tear patterns are classified to longitudinal, horizontal, or transverse features according to the mechanism of injury. Work-related meniscal tear usually occurs with a repetitive usage of the foot, hence it can be classified as a cumulative traumatic disorder. We found a 47 year-old female worker who had been taking charge of repetitive foot-switch stepping for 8 years. She suffered from pain in the right knee since 5 months ago. Tenderness along the medial joint line of the right knee was observed and pain was aggravated with full flexion of the right knee. On magnetic resonance imaging, high signal intensity was observed at the posterior horn of the medial meniscus of the right knee. Degenerative longitudinal and transverse complex tear in the medial meniscus was observed on arthroscopy. Arthroscopic partial meniscectomy was performed. We surveyed the work process and the health status of co-workers. It turned out that the work process was compatible to injure the meniscus and nine out of fourteen co-worker(64.3%) complained pain of the knee. No other factors related to her meniscal tear could be found except for the situation at her work. Therefore, we conclude that meniscal tear is related to the repetitive stepping of foot switch.

  • Arthroscopy has become an attractive modality in the diagnosis and treatment of joint diseases in toy breed dogs. However, the application of arthroscopy is limited by small joint space. Our objective was to evaluate the efficacy of a stifle lever for joint distraction during stifle arthroscopy in toy breed dogs. Paired stifles (n = 32 each) collected from 16 cadavers of toy breed dogs were randomly assigned to one of two groups: the stifle lever group or the external manipulation group. All stifles underwent arthroscopic cranial cruciate ligament transection, and the visualization of the medial meniscus was evaluated. Medial meniscal release (MMR) was then performed. Following arthroscopic examination, the success rates of MMR and damages of tibial and femoral cartilages were evaluated. Visualization of the medial meniscus was significantly better, and meniscal probing was significantly easier, in the stifle lever group than in the external manipulation group (p = 0.001). There were no significant differences between groups for MMR success or articular cartilage damage. Using the stifle lever on arthroscopic examination improved visualization and probing on the medial meniscus in toy breed dogs. The stifle lever can be used as a good modality in assessing medial meniscal pathology in toy breed dogs.

  • A 4 years old male mixed breed dog, which weighed 25.5 kg, referred to Veterinary Teaching Hospital at College of Veterinary Medicine in Chonnam National University, because of chronic hindleg lameness. Click sound by flexion and extension of stifle joint, positive reaction by cranial drawer movement, fat pad sign and tibial position in cranial drawer position on the lateral radiographic view, medial patellar luxation (grade II), and lameness score 2.5 at standing and 2 at walking in right hindleg were showed. Under general anesthesia with enflurane, after medial arthrotomy, it was performed to remove remnants of cranial cruciate ligament and torn medial menisci and joint closed. In modified retinacular imbrication technique, one lateral fabellar/tuberosity suture, one medial fabellar/tuberosity suture, and one imbrication suture adjacent to the patella were placed. At 9 days after operation, lameness score 0 was observed and general condition was excellent.

  • Purpose : The purpose of this study was to evaluate the results of arthroscopic meniscal repair according to joint stability. Materials and Methods : Twenty cases were reviewed, which had underwent arthroscopic meniscal repair. The mean age was 32.3 years old. The mean follow-up period was 59.7 months. Menisci that had underwent complete repair of associated ligament injuries (8cases, Sa) and menisci that had no associated ligament injury (9 cases, Sb) were classified as stable group (S), and the others (3 cases) as unstable group (U). Also stable group was divided into acute and chronic group. The result was evaluated with Lysholm score and IKDC method. The statistical analysis was done using Wilcoxon rank sum test and Fisher's exact test (p<0.05). Results : Group Sa had $87.5\%$ satisfactory and Lysholm score was 90.9. Group U had $66.7\%$ satisfactory, and Lysholm score was 77.7. Group Sb had $89.9\%$, satisfactory and Lysholm store was 91.4. In acute group $91.7\%$ was satisfactory, Lysholm score 92.5, in chronic group $80\%$ was satisfactory, Lysholm score 88.6. Conclusion : Joint stability was important factor for the outcome of meniscal repairs. So, it is desirable to repair meniscus injury early and the repair of associated ligament injuries should be performed together.

  • Purpose : We performed routinely arthroscopy to diagnose and treat intra-articular soft tissue pathology and tibial condylar fractures. The purpose of this study was to evaluate clinical value of arthroscopy in the tibial condylar fractures. Materials and Methods : The 31 tibial condylar fractures was examed by routine arthroscopy, 9 treated by conservative method and 22 treated by surgery at least follow up of 12 months. The authors analysed to the cause, classification, soft tissue injuries such as ligaments and menisci, treatment and results. Results : The most common type was Schatzker classification type I in 15 cases$(18\%)$ and intra-articular lesions and associated ligament injury were in 21 cases$(67\%)$. Most common lesion was meniscal tear in 16 cases and most common type of meniscal lesions was peripheral detachment in 7 cases$(44\%)$. Schatzker I, II fracture patterns were associated with the highest frequency of soft tissue injuries, especially medial collateral ligament and meniscal injuries. Conclusion : Arthroscopic examination is useful method to evaluate the intra-articular pathology and to treat the tibial condylar fractures.

  • We reviewed the charts and photos taken during arthroscpy of 218 knees of 214 patients(240 menisci) retrospectively. The male was 156 cases(73%) and the female 58 cases(27%). The mean age of the patients was 35 years(range, 7-68). The patients who had definite trauma history were classified as trauma group(Group 1), and the patients who had no or could not recall trauma history were as atrauma group(Group 2). The trauma group was subclassified into the the patients with sports injury, traffic accident, fall down, slip down, direct injury, and miscellaneous according to the causes of the trauma. The patterns of meniscal tear were classified into longitudinal, bucket-handle, horizontal, transverse, flap, complex, and degenerative tear on the basis of O'Connor's classification. The aim of this study was to compare the meniscal tear patterns between trauma group(Group 1) and atrauma group(Group 2) and between the patients before and after the age of 40. The results were as follows ; 1) The difference in the incidence of tear between medial and lateral meniscus was not significant statistically. 2) In Group 1, 60% of the cases showed the longitudinal and bucket-handle tear and 52% of the cases of Group 2 were horizontal tear. 3) In the patients before the age of 40, the longitudinal and bucket-handle tear were 52% of the cases and in the patients over 40, tear patterns which were thought to be related to degenerative change, horizontal and degenerative tear were more than half of the cases (51%).

  • 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.

  • Complete radial tears of the lateral meniscus are relatively rare. Once torn, the injury can be debilitating due to disruption of the circumferential fibers of the meniscus. We experienced a case of a lateral meniscus with a complete radial tear at the midbody, where the two torn ends were displaced more than 1 cm and could not be approximated during arthroscopy. Thirteen months after surgery, follow-up MRI and second-look arthroscopic findings showed that the complete radial tear has healed spontaneously. However, twenty nine months after the second-look arthroscopy, the patient complained of severe knee pain during exercise. On follow-up MRI, increased sclerosis and newly developed bone marrow edema were observed in the lateral femoral condyle, compared with previous MR images. Finally, we performed meniscal allograft transplantation due to the defective properties of the completely healed lateral meniscus.

  • 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.
