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 this study was to compare the efficacy of bone-patellar tendon-bone(B-PTB) allograft with autograft B-PTB reconstruction of anterior cruciate ligament(ACL) according to the subjective and objective criteria. Materials and Methods : 42 patients were treated for acute rupture or chronic insufficiency of the ACL between March 1993 and June 1996. There were 18 autografts and 24 allografts for ACL reconstruction. At 2 years of follow-up after operation, autograft and allograft groups were compared based on subjective, objective criteria and Telos stress arthrometer. Results : The modified Feagin Scoring System revealed 16 patients$(88.9\%)$ with a satisfactory result by autografts, but 21 patients$(87.5\%)$ with a satisfactory result by allografts after 2-years follow-lip. There was no statistically significant difference between the two groups. ACL reconstruction with B-PTB allograft did not produce a significant functional deficit. But patellofemoral pain and crepitus were more frequent in the autografts$(33.3\%)$ than allografts$(8.3\%)$ (p<0.05). Conclusion : The ACL deficient knees treated with allografts for ACL reconstruction tended to be better than those reconstructed with autografts fur the reduction of patellofemoral crepitus and pain. B-PTB allograft provides an acceptable alternative to autograft tissue for reconstruction of the ACL.

Purpose: To evaluate the outcome of the two-bundle anterior cruciate ligament reconstruction with single femoral tunnel and tibialis anterior tendon allograft and to determine any functional advantages. Materials and Methods: From June 2006 to March 2008, we performed single femoral tunnel and two-bundle ACL reconstruction with tibialis anterior tendon allograft in 26 cases. Mean age was 35.5 years. 20 cases were male and 6 cases were female. Average follow-up period was 2 years and 5 months, range from 1 year to 3 years and 5 months. Subjective and objective parameters were utilized in analyses, such as the mean range of motion, Lysholm knee score, Tegner activity score, Lachman test and IKDC score. Results: Postoperative mean Lysholm knee score, IKDC Evaluation Form, Tegner activity scale, Pivot shift test, and anterior displacement by the Telos stress test demonstrated statistically significant differences compared to the preoperative. Conclusion: Two-bundle anterior cruciate ligament reconstruction with single femoral tunnel showed good clinical results and was good operative technique.
Purpose: The purpose of this study is to investigate the relationship between rotator cuff tear and nerve injury, and prevalence of nerve injury using electromyographic study. Materials and Methods: From May 2004 to Feb. 2005, 19 cases, who underwent surgery for full-thickness rotator cuff tear, were evaluated for nerve injury using electomyogram instruments preoperatively. Rotator cuff tears caused by acute high energy trauma were excluded in this study. Mean age was 59 (range, 45-87) years and mean duration of symptoms was 45 (range, 1-360) month. Results: There were six nerve injuries (31.6%). All of them were incomplete brachial plexus injuries, and mainly postganglionic lesions. Four cases among them had minor trauma history. There were no significant differences in terms of cuff tear size, range of motion, pain score and functional score between groups with and without nerve injury. Conclusion: This study showed high prevalence (31.6%) of nerve injury in full-thickness rotator cuff tear. So careful physical examination and evaluation for nerve injury are needed in rotator cuff tear.

The characteristics of the patients after the calcaneal fracture that were associated with an unsatisfactory outcome were subtalar incongruity, decreased Bohler angle ratio of the fractured to the normal side, an age of more than fifty years, work involving strenuous labor, and increased time missed from work due to the injury. The purpose of this study was to examine the reliability of measurements of the range of motion of the subtalar joint. To determine reliability, evaluates of the correlatioinship between the degree of the displacement of the subtalar joint and Circle draw test after the calcaneal fracture. Fifty patients who had had fifty five calcaneal fractures were managed with open reduction and internal fixation. The results were reviewed retrospectively, between 4months and three years after the operation, with use of an evaluation system for the subtalar joint and with plain radiographs. At follow up evaluation, the result was assessed on the basis of restoration of anatomy and function of the subtalar joint. We evaluated the subtalar joint with plain films that consist of anteroposterior projection, lateral projection, calcaneal axial view, and Broden's view, and the measurements of the displacement of the subtalar joint surface after the calcaneal fracture. And we evaluated the range of motion of the subtalar joint with Circle draw test for physical evaluation. Circle draw test was evaluated and demonstrated the motion of flexion-supination-adduction and extension-pronation-abduction of the subtalar joint. And there are correlationship between the degree of the displacement and range of motion of the subtalar joint after the calcaneal fracture. The report critically reviews methords used to measure Circle draw test for physical examination of the follow up after the calcaneal fracture.

Purpose: The purpose of this study was to suggest an appropriate treatment method by comparing nonsurgical treatment and surgical treatment for enchondroma in the hands and feet. Materials and Methods: Seventy four cases with enchondroma of the hands and feet from January 1996 to March 2017 were selected to evaluate the functional outcomes. Thirty cases were treated with nonsurgical treatment, and 44 cases were treated with surgical treatment, such as curettage only or curettage with a bone graft. The mean follow-up period was 18.1 months. The functional results were analyzed using the Wilhelm and Feldmeier formula. Results: The mean age was 38 years, and the age range was between eight and 69 years. According to the Wilhelm and Feldmeier formula, the mean score of hand enchondroma was 3.09±0.85 and 3.20±0.91 in the non-operative and operative group, respectively. The mean scores of the foot except for the grip strength were 2.57±0.79 and 2.75±0.50, respectively. No significant difference was observed according to the functional results. Among the 18 cases of enchondroma with pathological fractures, nine cases were treated non-surgically and nine cases were treated by surgically. In all 18 cases, complete bone healing was observed at the final follow-up. Conclusion: Relatively satisfactory results were obtained in both surgical and nonsurgical treatment and there was no significant difference in functional outcomes. In cases of enchondroma in the hands and feet, nonsurgical treatment can also be a good treatment option.
Purpose: Evaluation and analysis of the incidence of postoperative complications after arthroscopic anterior cruciate ligament reconstruction using bone-patellar tendon-bone autograft. Materials and Methods: We reviewed 172 cases of arthroscopic anterior cruciate ligament reconstruction using bone-patellar tendon-bone autograft in anterior cruciate ligament tear without meniscal injury. We performed Lysholm knee score and KT-2000 testing, simple radiograph, physical examination as evaluation factor. Also, around knee pain, swelling, limitation of motion, patellofemoral crepitation, paresthesia and pain on kneeling were evaluated. Results: The average follow up period was 49.8 months. In 172 patients, 148 males and 26 femlaes were evaluated. The average age was 34.4 years. The Lysholm knee score improved from 51.9 points preoperatively to 90.8 points at final follow up. Clinical outcome was excellent in 83%, good in 11%, fair in 4% and poor in 2%. There were many cases of complications, 24 cases (14%) of around knee pain, 12 cases (7%) of swelling, 45 cases (26.2%) of patellofemoral crepitation, 52 cases (30%) of donor site paresthesia, 65 cases (38%) of pain on kneeling, 10 cases (5.8%) of limitation of motion at extension, 13 cases (8%) of limitation of motion at flexion and 2cases (1.2%) of patellar fracture. Conclusion: Although arthroscopic anterior cruciate ligament reconstruction using bone-patellar tendon-bone had good clinical results, many complications were noted. Some factors in surgical technique were suspected to be related to the complications and long term follow up will be necessary to further evaluated.

Purpose: To report two cases of bone tumors other than osteoid osteoma in the proximal femur and treated with percutaneous high frequency radioablation method. Cases: We reviewed two cases with intracortical chondroma and enchondroma in the femoral head retrospectively. The patient with intracortical chondroma was a thirty one year old woman and had suffered right hip pain of 1 year duration. The lesion was located in the head of right femur and treated with CT guided percutaneous high frequency radioablation after needle biopsy under general anesthesia. The symptom was gone immediately after the procedure and was discharged postop. 1 day. 15 months has passed without symptom recurrence. Second case having enchondroma, was 56 year old woman complaining of gluteal area pain for 3 months. Radiologic evaluation showed osteolytic lesion with sclerotic rim on the inferior portion of the left femoral head. She received a same therapy with CT guided radiofrequency ablation following needle biopsy. She reported dramatic pain relief after the procedure and was discharged postop. 1 day. No symptom has occurred for 3 months until now. Conclusion: We present 2 cases of bone tumor occurred in the hip joint area other than osteoid osteoma which were treated with CT guided radiofrequency ablation.
The primary purpose of a TKA is to restore normal knee function Therefore, ideally, a TKA should: (a) maintain the natural leverage of the knee joint muscles to ensure generating adequate knee muscle moments to accomplish daily tasks such as rising from climbing stairs; (b) provide adequate knee joint stability. A 16-channel MyoResearch XP EMG system was used to collect the differential input surface electromyography signals VM, VL, RF, BF, ST during climbing/descending stair tests. A Peak Motion Measurement System was used to collect the kinematic and kinetic data. AKIN-COM Ill isokinetic dynamometer was used for EMG of VM, VL, RF, BF and ST during maximal voluntary contraction. I Quadriceps EMG results for the VM of the passed 1year group limb demonstrated significant less RMS EMG than that of the passed 3year group limb $60^{\circ}-15^{\circ}$ of knee flexion(p<0.05). The VL of the passed 1year group limb also demonstrated significants less RMS EMG than that of the passed 3year group limb from $60^{\circ}-45^{\circ}$ of knee flexion(p<0.05). Similar to the VM and VL, the RF of the passed 1year group limb showed less RMS EMG than that of the passed 3year group limb from $60^{\circ}-30^{\circ}$ do knee flexion(p<0.05). Hamstring EMG results for the BF of the passed 1year group limb demonstrated less RMS EMG than that of the passed 3year group limb from $75^{\circ}-15^{\circ}$ of knee flexion(p<0.05). The passed 1year group limb tended to have less ADD displacement(p<0.071) than that of the passed 3year group limb. There was no significant difference of the ABD displacement between the passed 1year group and the passed 3year group limbs(p<0.73). The passed 3year group used compensatory adaptation movement strategies to compensate for the strength deficit of passed 3year group limbs. The passed 3year group limb also increased the quadriceps muscle activation level to produce more knee extension moment to compensate for the short quadriceps moment arm. The passe 3year group limb might have an unstable knee joint in the medio-Iateral direction during the climbing/descending by showing a tendency of more ADD displacement and greater hamming co-activation EMG than the passed 1year group limbs. The TKA design was not able to help the knee joint to produce adequate knee extension moment with less quadriceps muscle effort. I think that old man needs continuous exercise for muscle strength.

Purpose: To evaluate the clinical results of anterior cruciate ligament (ACL) reconstruction and to know the results of physeal injury by transphyseal tunnel in adolescents who had remaining growth potential. Materials and Methods : This study involved 12 patients under 19 years old out of 445 patients, who underwent ACL reconstruction between 1993 and 2001. The mean age at the time of operation was 15.9 $(13.1\~16.9)$ years and fellow-up period was 45.1 $(24\~120.6)$ months in avrarge. Autologous quadrupled hamstring tendon was used as graft in 11 cases and bone-patellar tendon-bone in 1 case. Clinical results were evaluated by Lysholm Knee Scoring Scale, range of motion and return to preinjury sports activities. Radiologic results were evaluated by $Telos^{\circledR}$ device. Bone maturity were analyzed by chronological age, standing height and the width of growth plate in AP and lateral view of knee joint at preoperatively. The growth disturbances were evaluated by measuring femorotibial angle, anatomical and mechanical lateral distal femoral angle, mechanical medial proximal tibial angle and leg length and by comparing those of uninjured site in last follow-up teleoroentgenogram. Results : The mean Lysholm Knee score was 51 $(25\~63)$points preoperatively and 98 $(94\~100)$ points at last follow up. The mean anterior displacement of the tibia by using $Telos^{\circledR}$ device was improved from 13.5 $(6\~27)$ mm to 2.9 $(1\~4)$ mm and there were no significant instabilities of the knee in all cases. There were no leg length discrepancies over 1 cm and no statistically significant abnormal alignment of the knee joint in all cases. Conclusion: ACL reconstruction using transphyseal tunnel for restoring stability and knee function is assumed as a good mettled of treatment without significant leg length discrepancy and abnormal alignment of the knee joint.
