Purpose : The purpose of this paper is to analyze the clinical results after meniscal repair using meniscal arrow. Materials and Methods : Between May 1997 and Aug 1998, we repaired 22 tom menisci in 22 patients using meniscal arrows. There were nineteen males and three females with an average age of 27 years. There were longitudinal tear in 14 cases, Bucket-handle tear were 7 cases and horizontal tear was in 1 case. In 22 meniscus tears, 16 cases were associated with anterior cruciate ligament tear. Average number of meniscal arrow that was used were 2.5(ranged 1 to 4). Average follow-up period was 14.7 months(ranged 6 to 22 months). We evaluated the clinical results by the Tapper and Hoover's grading system. Results : There were excellent in 16 cases, good in 4 cases and fair in 2 cases on the clinical results. At the last follow up, the range of the motion of the knee joint were average 135 degrees(ranged 125 to 140 degrees). Mean time elapsed for meniscal repair were 25 minutes(ranged 15 to 40 minutes). Conclusion : Meniscal arrow has many advantages such as short operative time, easy fixation technique, and less neurovascular injury. We think that arthroscopic meniscal repair using meniscal arrow is effective treatment method in selected patient who have longitudinal, bucket-handle tear at the posterior hom associated with anterior cruciate ligament tear.

The objective of this case report was to evaluate meniscal suturing for a young patient with a chronic radial tear of the incomplete discoid lateral meniscus. The patient underwent saucerization in conjunction with repair of the displaced radial tear of the discoid meniscus. Six-months after surgery, arthroscopic examination showed the repaired meniscus to be healed well with good continuity. Repair of radial tears, even chronic tears, should be considered for young patients with torn discoid lateral menisci.

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 analyze the clinical result of the arthroscopic decompression of meniscal cyst and meniscus resection or repair of meniscus tear. Materials and Methods : From April 1994 and October 2001, 19 patients with diagnosis of meniscal cyst associated with tears of the meniscus were treated by arthroscopic meniscal resection or repair with decompression of the cyst. The mean age was 39.8 years(range, 22-58years). The follow-up period ranged from 3 months to 36 months with an average of 18 months. Seven of 19 patients had tenderness over the joint line with palpable mass. Treatment consists of arthroscopic resection or repair of meniscal tear with decompression of the cyst through transmeniscal approach. Open excision of cyst was performed in one case. Clinical evaluation was performed using Lysholm knee score and Tegner activity. All cases were executed proper treatment using arthroscopy. Results : Twelve cysts involved the lateral meniscus$(64\%)$ and seven cysts were on medial cyst$(36\%)$. Most of lateral meniscal cysts were located in anterior one-third and medial meniscal cyst were on posterior one-third. Meniscal tear were observed in seventeen cases$(89.5\%)$ and most tears were horizontal$(79\%)$. Preoperative symptom disappeared and no cyst recurrences were observed at last follow-up(mean follow-up: 18 months). Conclusion : Meniscal cysts involved lateral side in $64\%$ and most of them were associated with meniscus tear$(89.5\%)$ which consists of mainly horizontal component$(79\%)$.

Purpose: All-inside meniscal repair using FasT-Fix (Smith & Nephew Endoscopy, Andover, Massachusetts, USA) is a popular method for the meniscal tear. However, there was no report after all-inside repair using FasT-Fix for the meniscal tear in Korea. Therefore, the purpose of this retrospective study was to report clinical outcomes after all-inside meniscal repair using FasT-Fix. Materials and Methods: 25 consecutive patients underwent meniscal repairs using FasT-Fix for tears of the posterior horn of the medial or lateral menisci combined with hamstring anterior cruciate ligament (ACL) reconstructions. Postoperative evaluations included Lysholm knee score and Tegner activity scale. Using clinical criteria, a repaired meniscus was considered healed if there was no effusion or joint line tenderness, negative McMurray test, and no sense of giving way. Results: The average follow-up was 47.9 months (range, 40 to 61 months). At follow-up, the mean Lysholm score was 91.8 and the mean Tegner activity scale was 5.6. According to clinical criteria, 20 (80%) menisci was healed, and 5 (20%) failed. Conclusion: All-inside meniscal repair using FasT-Fix showed satisfactory results in patients with hamstring ACL reconstructions.

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.

Most of bucket handle meniscal tears are associated with anterior cruciate ligament (ACL) deficiency. Lateral meniscus lesions are more common with acute ACL deficiency, where medial meniscus lesions are more associated with chronic ACL deficiency. We reported an ACL deficient knee with bucket handle tears of medial and lateral meniscus of the same knee. The report suggests the need for increased awareness of the possible presence of this. Additionally, we discuss injury mechanism, clinical symptoms, specific signs on Magnetic Resonance Imaging (MRI), and treatment options.

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 was to determine the clinical outcome of meniscal repairs according to tern location and combined injury. Materials and Methods : From 1994, 73 meniscal repairs were underwent by arthroscopy and followed more than 1 year. The locations of torn meniscus were 29 red-red Bone, 36 red-white zone, 8 white-white zone. Twenty-six patients also had combined lesion including ACL injury 17 cases and treated simultaneously. Clinical result was evaluated by OAK system. Result : Healing rates(above good) were $94\%$ in isolated injury and $88\%$ in combined injury, especially $94\%$ in ACL injury. The result according to tern location were $90\%$ in red-red zone, $91\%$ in red-white zone, all in white-white zone. Conclusion : Meniscus tear with ACL injury should be repaired by arthroscopy, simultaneously. The meniscal tear of white-white zone could be healed by arthroscopic meniscal suture.

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.
