Purpose : To compare the mid term with long term follow up results of the anterior cruciate ligament(ACL)> reconstruction using patellar tendon. Materials and Methods : Seventy-six cases, which could be followed up more than 2 years were included in this study. They were classified into two groups, mid-term group(41 cases) with mean follow-up periods of 2 years and 10 months and long-term group(35 cases) off years and 6 months. Clinical and radiological results and peripatellar complications were evaluated & compared. Results . There was no statistically significant difference in radiological finding and anterior instability between two groups. However, the incidence of anterior knee pain, paresthesia at incision site, kneeling pain, crepitus and quadriceps weakness was lower in long-term group than in mid-term group. Conclusion : ACL reconstruction using patellar tendon graft could successfully restone the stability of knee joint, but there are some complications in donor site and patellofemoral joint. However this complications were gradually decreased with long term follow-up.

Purpose: To evaluate the effectiveness of extracorporeal shock wave therapy (ESWT) for postoperative pain after surgery around ankle. Materials and Methods: We included 21 patients who performed an operation around ankle from 2009 to 2013. 4 times ESWT were applied to the patients who have tenderness more than visual analog scale (VAS) point 4. We evaluated the VAS at each sessions and final follow-up, and American Orthopedic Foot and Ankle Society ankle-hindfoot score (AFOAS) was checked at preoperative and final follow-up. Patient's satisfaction and complications were surveyed. Results: Preoperative VAS was mean 4.7, postoperative pain VAS was mean 6.0 at 4.5 months follow-up. The VAS after ESWT each session at 1, 2, 3 weeks and final follow-up were 4.8, 3.2, 2.3, 2.9, respectively. Mean final follow-up period was 9.4 months. Final VAS were significantly decreased (p<0.001). Final VAS were increased from VAS at last session of ESWT, however, not significant (p=0.189). AOFAS significantly improved from preoperative 60 to final follow-up 86 (p<0.001). Excellent was 12 patients (57%), good was 4 patients (19%), no change was 3 patients (14%) and poor was 2 patients (9%). 1 patient complained a dizziness and nausea during ESWT. Conclusion: ESWT for postoperative pain after ankle surgery shows satisfactory pain reduction in 76% of all patients without severe complication.

Purpose: To analyze the clinical results and second look arthroscopic findings of anterior cruciate ligament(ACL) reconstruction with a tibialis anterior tendon allograft and a hamstring tendon autograft. Materials and Methods: We reviewed the cases of athroscopic ACL reconstructions using allogenous tibialis anterior(TA) tendon and autogenous hamstring tendon done from March, 2002 to August, 2005 and followed-up more than 1 year. The 250 cases were included in this study and allogenous TA tendon was used in 150 cases and autogenous hamstring tendon in 100 cases. The mean follow-up period was 15 months and 14 months, respectively. The clinical evaluation was done by Lachman test, Pivot shift test, KT-1000 arthrometer and International Knee Documentation Committee(IKDC) knee score. Graft tension, synovial coverage were observed in cases of second look arthroscopy. Results: At final follow-up, there was no significance between the two groups in clinical examination. On second look arthroscopy, synovial coverage was better in autogenous hamstring tendon group than allogenous TA tendon group(p=0.005). But no difference was found in graft tension(p>0.05). Conclusion: There were no significant differences between the two groups in the clinical results. But autogenous hamstring tendon group had better synovial coverage than allogenous TA tendon group in second look arthroscopy.

Objective : The purpose of this study was to investigate the effect of sensory integration therapy and home program intervention on the visual attention of children with Down syndrome. Methods : This study used a single subject design for one child with Down syndrome, Sensory integrated treatment intervention was conducted once a week for 16 weeks, and home programs were conducted four times a week for 16 weeks. Changes in visual attention were measured after intervention in the target child. Results : After the intervention, the average values of object gaze, object horizontal pursuit, and object vertical pursuit time increased compared with the baseline period. In object gaze, object horizontal pursuit, and object vertical pursuit, a section higher than the ±2 standard deviation of the baseline period was observed during the intervention period. Conclusion : This study confirmed that the combination of sensory integrated therapy and home program intervention improved visual attention and visual perception in children with Down syndrome, and it is meaningful that it presented an effective intervention method.

Purpose: To evaluate the long-term clinical results and survivorship of unicompartmental knee arthroplasty (UKA) in elderly patients older than 70 years by analyzing cases that have been implanted for >10 years ago. Materials and Methods: The long-term follow-up results were evaluated in 39 patients (46 cases) who underwent medial UKA from March 2002 to February 2004. The mean age of the patients at the time of surgery was 74.0 years, and the preoperative diagnosis was degenerative arthritis of the knee in all cases. Results: Of the 46 cases, reoperation occurred due to the complications in four cases. In 22 cases without 14 cases of death and six cases of follow-up loss, follow-up more than 10 years was possible. The mean Knee Society knee and function scores improved significantly from 53.0 and 52.5 points pre-operatively to 89.4 and 80.9 points at the last follow-up, respectively (p<0.001). The mean range of motion of the knee recovered to 132.5°, and the mean tibiofemoral angle changed to 5.9° of valgus at the last follow-up. Complications following the UKA occurred in four cases; the most prevalent complication was mobile bearing dislocation (n=2). One case of failure occurred due to aseptic loosening and degenerative arthritis of the lateral compartment, respectively. The cumulative survival rate of the implants was 95.0% at 10 years and 85.7% at 15 years. Of the 40 cases, excluding six cases of follow-up loss, 36 cases (90.0%) could be used without reoperation until death or at the last follow-up after surgery. Conclusion: These results showed the outstanding functions of the knee and satisfactory long-term survivorship after UKA. Therefore, UKA could be a useful method for the treatment of osteoarthritis of the knee in elderly patients older than 70 years of age.

Purpose: To evaluate the long term results of surgical treatment for sacral chordoma. Material and Method: We reviewed the records of 4 patients with sacral tumor treated surgical resection. Mean follow-up duration was 8.3 year(3~11). All cases were performed complete resection of tumor mass through posterior approach in 3 cases and anterior-posterior approach in one. The most caudad nerve-roots spared were the second sacral roots in one and the third sacral roots in 3 cases. Functions of voiding and defecation including neurological symptoms of lower extremities, other complications of surgical treatment, and local recurrence or distant metastasis of tumor were evaluated. Result: There was no motor deficit in all cases, but radiating pain was developed in one and wound infection in one. Bladder function was preserved in 2 cases, intermittent incontinence in one, and doing intermittent catheterization in one. Bowel function was preserved in one and 2 cases were suffered from constipation. At the last follow-up, disease-free was in one, local recurrence in one, and local recurrence with distant metastasis in one. Conclusion: The result of surgical resection for sacral chordoma is satisfactory showing average 8 years survival. Early detection and aggressive surgical treatment is the best to prolong survival and to minimize functional deficit with preservation of upper sacral nerves.

Purpose : To validate the arthroscopic synovectomy for the treatment of hemophilic knee. Materials and Methods: From January 1996 to January 2001, 28 arthroscopic synovectolny were performed in 26 patients with hemophilic arthropathy of the knee. The mean age was 17.8 years. The mean follow-up period was 3 years 11 months. We used six portals (two anterior, two suprapatellar and two posterior) and posterior trans-septal portal in all cases. Result : The mean frequency of hemarthrosis was 4 times per month preoperatively and 2 postoperatively. The mean amount of factor replacement was 4,633 units preoperatively and 1,505 postoperatively. The mean range of motion was $112^{\circ}$ preoperatively and $107^{\circ}$ postoperatively. On radiographic evaluation, three cases were progressed at the latest follow-up. On the subjective evaluation, significant or moderate improvement were in 19 cases $(68\%)$, and no improvement or deterioration in 9 cases $(32\%)$. Conclusion : With complete synovectomy through the appropriate arthroscopic portals, arthroscopic synovectomy of the knee in hemophilic patients is the successful method in decreasing bleeding episodes, amount of factor replacement, knee pain and preventing or delaying onset of end-stage hemophilic arthropathy.
