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: This study examined clinical cure and patients' satisfaction degrees by factors influencing surgical operation results, after arthroscopic inside to out repair as a nonabsorbable suture material, in case of meniscal rupture. Materials and Methods: Materials were 110 cases of 95 patients who could make paces for over 12 months from August 1999 to June 2002. Results were evaluated by clinical cure and subjective satisfaction degrees. This study, concerning those results, analyzed age, term from taking pictures to taking surgical operation, rupture section, rupture length, rupture types, lesion of articular-cartilage, and effects of anterior cruciate ligament operation accompanied. Results: 84 cases(76%) were clinically cured, 98 cases(89%) were subjectively satisfied. In case of accompanying anterior cruciate ligament rupture, and in case that rupture length was below 2 cm, rates of clinical cure and patients subjective satisfaction were significantly high. In case of complex or degenerative rupture, patients satisfaction rates were higher when comparing with clinical cure rates. Conclusion: Various sutures are possible as well as available in case of arthroscopic meniscal inside to out repair using nonabsorbable suture material. It can be concluded that patients age is not absolte consideration in determining the suture of meniscus. In cases of complex rupture, degenerative rupture, ruptures companied by joint-cartilage injuries, considerate consideratin need be paid to choose patients and operations.

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.

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.

Objectives : In this case, the knee joint inconvenience with deteriorating pain has been relieved by acupuncture treatment for a patient was 51-year-old male with a left medial meniscal posterior horn rupture in 2012. Methods : Twenty-four times of acupuncture treatments were performed for Twelve weeks from July 2016 to improve the disease. SP8(Jigi; 地機), BL63(Geummun; 金門), KI3(Taegye; 太谿), LI4(Hapgok; 合谷) were chosen for treatment by principles of Traditional Korean Medicine. Results : Numeric Rating Scales, which means subjective pain, decreased from 6 points to 3 points out of 10 points in total. Pressure Pain Threshold, which means sensitivity to pressure applied to the affected area, increased from 21N to 47N on the lateral-inferior side and from 19N to 50N on the lateral side. K-WOMAC, which indicates discomfort of knee-related activity, was 56 points out of 96 points in total before treatment and 4 points after treatment, 13 points after two years, and 15 points after four years. However, MRI tests conducted before and after treatment did not identify any significant changes. As a result, we confirmed that a total of 24 acupuncture treatments had resulted in the relief objective and subjective pain and functional recovery, especially in the case of the knee function, maintained until after four years later. There was no significant substrate recovery in meniscal rupture.

A 30 kg, 6-year-old spayed female Samoyed dog was referred with a history of intermittent weight-bearing lameness in her right hindlimb for 3 weeks. The patient hadsurgery to correct a medial patellar luxation in the same limb 3 years prior. Based on the physical examination and radiographic findings, MPL and CCLR of the right hindlimb were diagnosed. Pre-surgical arthroscopy examination was performed, revealing a complete rupture of the cranial cruciate ligament, medial caudal meniscal tears and fibrotic cartilagechanges on the trochlear groove. An arthroscopy-assisted partial meniscectomy was used to repair themedial caudal meniscus. To correct the tibial plateau angle and medial patellar luxation, a tibial plateau leveling osteotomy (TPLO) was performed. A tibial tuberosity transposition (TTT) was performed to realignthe quadriceps mechanism with the trochlear block recession followed by soft tissue reconstruction. The post-surgical recovery was uneventful, and the patient was weight-bearing with normal ambulation on the repaired limb. There were no complications, and the implants were well positioned at the last follow-up. The clinical outcome of the caseindicates that combining TPLO with TTTis a good surgical option for treatingconcurrent CCLR and MPL.

Purpose : To analyze changes of the anterior translation, MRI findings and associated injuries at scarring of the torn ACL in the chronic ACL rupture. Materials & Method : From Dec. 1996 to May 2000, 19 patients who were diagnosed as the chronic ACL rupture were studied. We analyzed KT-2000 side to side difference of maximal manual anterior displacement(MMAD), MRI findings and associated injuries. Results : There was statistically significant difference in the average MMAD between the 7 cases$(37\%)$ with scar formation$(2.78{\pm}2.41mm)$ and the 12 cases without scarring$(5.75{\pm}2.52mm)$. The chronic ACL rupture without scarring had more meniscal injuries$(67\%)$ than with scarring$(28\%)$. MRI showed that relatively straight bands toward expected insertion site with single large fragment(5 cases) and continuous band with focal angulation(2 cases). Conclusion : If relatively straight bands toward expected insertion site with single large fragment or continuous band with focal angulation on MR imaging is showed in the patient without significant anterior translation at arthrometer, the possibility of the scar formation of the torn ACL should be considered. We think that the chronic ACL rupture with scarring had less meniscal injuries than without scarring will give additional information on the natural history of ACL injuries.

Purpose: The purpose of this study was to analyze the clinical results of symptomatic lateral discoid meniscus found in adults over 40 years old. Materials & Methods: From March 1994 to March 2004, 53 cases treated for lateral discoid meniscus in 48 patients aged over 40 years with the mean age $48.4(40{\sim}62)$ who were followed up more than 1 year, were analyzed by physical findings, simple X-ray, MRI and arthroscopic exam. Results: Most of the cases (42 cases, 79.2%) had symptoms for less than 1 year duration. 26 cases(49.1 %) out of 53 had trauma history. Simple radiologic evaluation showed that lateral condylar abnormality such as the flattening of lateral femoral condyle, marginal osteophytes, and subchondral sclerosis was seen in 37cases(69.8%). Also medial condyle showed degenerative changes in 16 cases (30.2%). Tear of discoid meniscus in 45 cases(84.9%) were examined by arthroscope and tear was not detected in 8 cases(15.1%). Type of tear was complex(18 cases), longitudinal(12 cases), horizontal(11 cases) and transverse(4 cases). Concomitant medial meniscal rupture was found in 7 cases(13.2%). The simple procedure done was reshaping(46 cases), subtotal resection(5 cases), total resection(1 case) and meniscal repair after reshaping in 6 cases, and arthroplasty was performed after arthroscopic examination in 1 case. Conclusion: Onset of symptom in adult lateral discoid meniscus is usually traumatic in origin. Most cases showed radiologic abnormality such as degenerative change in lateral condyles as well as medial condyles and the results of preservative surgical treatment was the most preferred option in most patients.

Purpose : The purpose of this study was to compare the pattern of displaced bucket-handle tear of lateral and medial menisci and the treatment modality and results from accompanying injury. Materials and Methods : Patients who were diagnosed for displaced bucket-handle tear of medial meniscus (group I: 52patients, 52cases) and lateral meniscus (group II: 31patients, 32cases) from September 1998 to December 2002. The mean ages were 25years $(16\~66)$ for Group I and 29years $(18\~63)$ for Group II, and the average follow-up period were 18months $(12\~44)$ and 13months $(6\~46)$, respectively. The zone of meniscus tear and the existence of accompanying injury were verified through intraoperative arthroscopy and discoid type meniscus was additionally examined for group II. The assessment was made according to the physical examination and clinical pattern at the postoperative last follow-up, and the 2nd look arthroscopy was performed in 19cases $(23\%)$ for the cases accompanying anterior cruciate ligament (ACL) injury in both groups. Results : There were 38cases $(73\%)$ in group I, 5cases $(16\%)$ in group II for associating ACL injury. We observed discoid type meniscus (19cases, $59\%$) in group II. At last follow-up clinical success in repair cases of group I and II are 22cases $(85\%)$, 2cases $(67\%)$, in resection cases are 26cases $(100\%)$, 26cases $(93\%)$ respectively. Reoperation is performed 2cases in repair cases of group I. One case is re-rupture, the other case is newly developed tear in white-white zone. Reoperation is performed 2cases due to remnant meniscal tear in resection cases of group II. All of 2cases are discoid type menisci. Conclusion : Displaced bucket-handle tear of medial & lateral menisci would be substantially different an aspect, considering on difference would help to select proper treatment modality.

Purpose: The purpose of this study is to describe causes and injury mechanisms during inline skating and to find preventive measures .Materials and Methods: We have carefully selected 57 patients who have been treated in our hospital and nearby hospital. There are 37 males and 20 females, and mean age is 9 years 9 months (range,6-40 years old) . We have meticulously investigated their injured sites, their favorite location for inline skating , their use of protective means while they were on the wheels and their injury mechanisms . Results: Injury consisted of 50 fractures,1 meniscal tear,2 medial collateral ligament rupture and 4 contusion or sprain. Fracture sites varied as follows : 33(66$\%$) cases in distal radius and ulna,5(10$\%$) in elbow. 3(6$\%$) in diaphysis of humerus, etc Location at the time of injury varied as follows : 22 cases(39$\%$) in their apartment complex, 19 cases in (33$\%$) narrow streets, and 16 cases(28$\%$) in parks Only five patients admitted that any means of protection were used.2 cases only had knee pad on , 1 case put on elbow pad in addition, and 2 cases put on wrist guard as well. However none of the patients had helmet on Conclusion: We would strongly like to stress the importance of using sufficient protections and of choosing area where it is safe to ride, in order to reduce the risk of accidents. In addition, continuous and effective prior education from inline skate circles may be in order before riding the inline skate.
