Objectives : To find effects of acupuncture, electro-acupuncture, low level He-Ne laser therapy(LLLT) at $TE_5$, $GB_{41}$ in the neuropathic pain. We made experiment on rats ligated L5 spinal nerve like general herniation of nucleus pulposus(HNP). Methods : A model of neuropathic pain was made by isolating Left 5th lumbar spinal nerve of rats. Three days after the neuropathic surgery, acupuncture and LLLT, electro-acupuncture was injected at $TE_5$, $GB_{41}$ one time a day for a week. Each group was divided two. one is opposite side performed the surgery which is right, another is left side performed the surgery. After that, the author examined the withdrawal response of neuropathic rats' legs by van Frey filament and acetone stimulation. And also the author examined c-Fos, Nociceptin and KOR-3 in the midbrain central gray of neuropathic rats. Results : As we have observed the effect of mechanical allodynia, LT-R group were diminished on 6th day compared with control group, EA-L group, EA-R group and LT-L group were diminished on 7th day compared with control group. As we have observed the effect of cold allodynia, EA-R group were diminished on 6th day, 7th day compared with control group. As we have observed the effect of activity of c-Fos in the central gray part, EA-R group and LT-R group were diminished compared with control group. As we have observed the effect of activity of Nociceptin in the central gray part, EA-R group were a little increased compared with control group but it is not reliability. As we have observed the effect of activity of KOR-3 in the central gray part, EA-R group were significantly increased compared with control group. Conclusions : We have noticed that effect of acupuncture at opposite side of sickness and powerful stimulation could be more effective, because of EA-R group have more controllable effect all test we have done on the other hand EA-L group have only effect on mechanical allodynia. This study can be used in clinical therapy for neuropathic pain. But it is not reliability that Nociceptin have effectively to control pain. Therefore We have to follow up about that.

Purpose : The purpose of this study is to evaluate the clinical outcomes and radiological changes after reconstruction of anterior cruciate ligament with human allograft. Material and Method : Authors analyzed 22 cases of anterior cruciate ligament allograft reconstruction which were done from January, 1995 to December, 1998 and could be followed up for a year or more. All cases were followed and reviewed in terms of anterior drawer test, Lachman test, Pivot shift test, radiographic examination, knee range of motion, and side-to-side difference of anteroior tibial translation using CA-4000 knee motion analyzer, and Lysholm knee scoring system. Result : The mean Lysholm knee score was 54 preoperatively and improved to 81 postoperatively by average of 27. The side-to-side difference of anterior tibial translation using CA-4000 knee motion analyser was less than 3 mm in 16 cases$(73\%)$, between 3 and 5 mm in 4 cases$(18\%)$, and greater than 6 min in 2 cases$(9\%)$. Average tibial tunnel enlargement was 1.5 mm, but there were not any osteoiysis or cystic formation along the tunnel and no relationship between tunnel enlargement and clinical outcome. Conclusion : Although this study had limited cases, clinical results of anterior cruciate allograft reconstruction were similar to those of reconstruction with autograft reported in the literatures. We think that allograft is an acceptable substitute fer autograft in anterior cruciate ligament reconstruction.

Introduction : This study compared the clinical results with biceps rerouting fer the isolated posterolateral instability (PLI) and for the PLI combined with PCL injuries. Methods : 21 cases of isolated PLI (group I) and 25 cases of PLI combined with PCL rupture were included in the study. The PLI was reconstructed by modified biceps femoris rerouting technique with PCL reconstructions performed prior to the PLI correction in cases of combined injury The clinical results were reviewed and analyzed. Results : Pre-operatively positive reverse pivot shift test turned negative in 43 cases post-operatively. Increased preoperative external rotation thigh foot angle (ERTFA) showed significant differences between the two groups and all fell within normal limits post-operatively At a mean follow-up of 40.3 months, the average Lysholm knee score and. The Hospital for Special Surgery Knee Ligament Score for group I and group II revealed above 90 points without statistically significant difference between the groups. 3 cases of tenodesis failure developed and re-operation was performed. Discussion and Conclusion : The advantages of modified Clancy technique include reduced surgical damages to the iliotibial band and fixation of the biceps tendon at the isometric position. The modified biceps rerouting technique is recommended for the reconstruction of both isolated and combined PLI except in patients with severe damages at the attachment of biceps tendon.

Purpose: The purpose of the study is to provide the clinical results of arthroscopic posterior cruciate ligament(PCL) reconstruction with preservation of the original PCL using transtibial tunnel and posterior transseptal portal. Materials and Methods: 36 patients underwent PCL reconstruction with achilles tendon allografts. We tried to preserve of the original PCL.At the final follow-up, patients were evaluated retrospectively by four measurements: Lysholm knee scores, IKDC grades, Telos stress radiography, and second look arthroscopy.Follow-up periods were from 12 months to 30 months. Results: The average Lysholm knee score improved from $66.0{\pm}8.67$ to $87.9{\pm}5.04$. Preoperative IKDC grades were abnormal in 15(41.7%) and severely abnormal in 21(58.3%), postoperative IKDC grades were normal in 6(16%),nearly normal in 24(66%), abnormal in 5(16%) and severely abnormal in 1(2%).The average side to side difference in Telos stress test decreased from $12.5{\pm}2.61(7{\sim}20)$ mm to $3.9{\pm}1.34(7{\sim}1)$ mm (paired sample T test, p=0.001) Conclusion: Arthroscopic posterior cruciate ligament(PCL) reconstruction with preservation of the original PCL using transtibial tunnel and posterior transseptal portal is useful surgical method.

Purpose: The purpose of this study was to compare the clinical outcomes of ACL reconstruction using autogenous hamstring tendon and allo-tibialis tendon. Materials and Methods: Between March 2002 and March 2005, We performed 30 ACL reconstuructions using hamstring autograft and 20 ACL reconstuructions using tibialis tendon allograft. The average follow up period was 22 months in auto-hamstring tendon and 18 months in allo-tibialis tendon. For the clinical evaluation, we measured the Lysholm score, International Knee Documentation Committee(IKDC) score and anterior laxity by KT-2000 arthrometer at final follow up and compare the results between two groups. Results: The Lysholm score improved from 69.5 preoperatively, to 95.3 at final follow-up in the hamstring autograft groups and from 69.0 to 90.4 in the tibialis allograft groups. According to the IKDC evaluation form, 80% of autogenous hamstring tendon group and 73% of allograft group were good results, higher than B(almost normal)(p>0.05). The average KT-2000 arthrometer side-to-side difference, decreased from 7.1mm preoperatively, to 1.8mm at final follow-up in the hamstring autograft groups and from 7.4 mm to 2.4mm in the tibialis allograft groups. Conclusion: The clinical results of ACL reconstruction using auto-hamstring tendon and allo-tibialis tendon showed no significant differences. The allo-tibialis tendon is an acceptable substitute for auto-hamstring tendon in ACL reconstruction.

Objective : The purpose of this study was to evaluate the clinical and radiological results after treatment of old ACL(anterior cruciate ligament) avulsion fracture of tibia. Materials and Method : 11 cases who were followed up at least 2 years after treatment in chronic ACL avulsion fracture of tibia were included in this study. The average age of patients was 26(9-66) years and the mean period of follow up was 53(24-131) months. After evaluation of the lesion and treatment of associated lesion under arthroscope, open reduction and internal fixation or fragment removal was performed. Pull-out suture was performed in 8 cases, screw fixation in 2 cases. Results : The Lysholm knee score was 64.3 in average preoperatively and improved to 96.2 average at follow up. On the Lachman test, there were mild(+) instabilities in 7 cases, moderate(++) in 4 cases. On the postoperative Lachman test, there were no instabilities in 9 cases, mild(+) instabilities in only 2 cases. According to Meyers and Mckeever's evaluation protocol, 9 cases $(81.8\%)$ were excellent, 2 case $(18.2\%)$, good. On preoperative instrumented anterior laxity test with $Telos^{\circledR}$, side to side difference in 201b was 7.8(10-4) min in average and 2.1(6-0) mm in average at follow-up. Conclusion : In chronic ACL avulsion fracture, it is thought that combination of arthroscopic evaluation of associated injury and open reduction and fixation and fragment removal can bring about satisfactory results.

Purpose : Preliminary report of the technique and trial of double bundle PCL reconstruction using Achilles allograft. Materials and Methods : From May 1999 to July 2000, 8 cases of PCL insufficient patients were treated with Achilles allograft reconstruction using the double bundle and double femoral tunnel technique. The tibial tunnel was prepared anteromedially. All other combined injuries within the knees were treated accordingly. Minimal follow-up period was 1 year. The results was assessed from the point of function and stability using Lysholm knee score and KT-2000 arthrometer. Results : Up to present follow up. 8 patients showed good sign of recovery with no instability (translation less than 2 mm) except olio that has been grafted-ligament rupture. In addition, none showed any sign of infection nor ROM limitation. Two complications were seen, which one had grafted-bone fracture and the other grafted-ligament rupture. The former occurred during operation and the latter occurred due to improper protection. Conclusion : Presently the follow up period is too short to draw any conclusive opinion but it is essential to select healthy and well sterilized allografts fur successful outcome. Double femoral tunnel technique seems to be more physiologic in PCL reconstruction. With these prerequisites, it seems to be a good alternative to use Achilles allografts fur the reconstruction of PCL. However, a longer follow-up is needed.

Purpose: The purpose of this study is to evaluate the radiologic and clinical results of the arthroscopic coracoclavicular fixation of the acute acromioclavicular dislocation using $TightRope^{(R)}$ (Arthrex, Inc, Naples, FL). Materials and Methods: We performed the arthroscopic coracoclavicular fixation using $TightRope^{(R)}$ in twenty patients with the Rockwood type III or V acute acromioclavicular dislocation between February, 2009, and February, 2010. Mean follow-up was 13.4(range 8~22) months. Radiologic results were evaluated by comparing the distances between the clavicle and the coracoid process with those in the contralateral sides using the acromioclavicular stress radiographs. Clinical results were made according to the KSS(Korean Shoulder Scoring System), and the cosmetic satisfaction of the patient was assessed. Results: Radiologically, 18 cases showed excellent, 1 case showed good and 1 case showed fair results. Clinically, KSS was mean 98.5 (range 92~100) points and all cases revealed satisfactory cosmetic results. Because one case complained of skin tenderness and discomfort of palpation, we closed the knot with surrounding muscle & fascia. Then local wound infection occurred, so we treated it by incision and drainage under local anesthesia and antibiotic therapy for 2 weeks. Conclusion: Arthroscopic coracoclavicular fixation using $TightRope^{(R)}$ for treating the Rockwood type III or V acute acromioclavicular dislocation showed satisfactory radiologic and clinical results. It seems to be a good treatment method that has little postoperative complication, provides an early rehabilitation and an excellent cosmetic result, and does not require secondary operation for removal of metal implant.

Purpose: We investigated the natural history of acute, isolated posterior cruciate ligament injuries treated conservatively. Materials and Methods: Between February 1999 and October 2006, we evaluated retrospectively the results of acute, isolated posterior cruciate ligament injuries treated conservatively. The subjects consisted of 21 patients. At initial and follow up visits physical examination, $KT-2000^{TM}$ arthrometer and MRI were performed to assess improvement on the knee stability and continuity of the posterior cruciate ligament. IKDC (International Knee Documentation Committee) knee scoring and quadriceps muscle strength were also checked in all population. Comparing the results of initial and follow up examinations we assessed the natural history of acute, isolated posterior cruciate ligament injuries treated conservatively. The mean follow up period was 22.7 months. Results: The posterior drawer test showed 14 cases of Grade I, 6 cases of Grade II and 1 case of Grade III progressing 18 cases of Grade I and 3 cases of Grade II. The mean difference of 5.7mm by $KT-2000^{TM}$ arthrometer was changed Into 2.7mm and the continuity of posterior cruciate ligament initially checked by 48.1% on MRI increased to 69.7%. The mean quadriceps muscle strength was grade 'Good' and mean IKDC knee score was nearly grade 'A'. Conclusion: Our study suggests that patients with acute, isolated posterior cruciate ligament injuries treated conservatively may get good clinical outcomes on clinical situation and MRI.
