Twenty-six patients (12 male and 14 female) with symptomatic scapular winging caused by serratus anterior dysfunction were managed with split pectoralis major tendon transfer (sternal head) with autogenous hamstring tendon augmentation from 1998 to 2006. Twenty-five patients had positive results for long thoracic nerve palsy on electromyography. The mean duration of symptoms until surgery was 48 months (range 12~120 months). Four patients had non-traumatic etiologies and twenty-two patients had traumatic etiologies. At the final follow-up assessment for functional improvement, a Constant-Murley score was used. 21 patients were completely evaluated, while 5 patients who had less than 12 months follow-up were excluded. Pain relief was achieved in 19 of the 21 patients, with twenty patients showing functional improvement. The pain scores improved from 6.0 preoperatively to 1.8 postoperatively. The mean active forward elevation improved from $108^{\circ}$ (range $20^{\circ}\sim165^{\circ}$) preoperatively to $151^{\circ}$ (range $125^{\circ}\sim170^{\circ}$) postoperatively. The mean Constant-Murley score improved from 57.7 (range 21~86) preoperatively to 86.9 (range 42~98) postoperatively. A recurrence developed in one patient. Of the twenty-one patients, eight had excellent results, nine had good results, three had fair results, and one had poor results. Most patients with severe symptomatic scapular winging had functional improvement and pain relief with resolution of scapular winging.

Purpose : The purpose of this study was to compare the results of ACL reconstruction using bone-patellar tendon-bone to hamstring. Materials and Methods : Thirty-two ACL reconstructions with autogenous BPTB and eighteen reconstructions with hamstring were compared in terms of functional outcome, stability and tunnel expansion. Results : The functional score of BPTB group was higher than hamstring group in OAK(Orthopadishe Arbeitsguppe Knie) and IKDC(International Knee Documentation Committee) system. In BPTB group, OAK scores were 71.6$({\pm}10.0)$ preoperatively and 88.5$({\pm}7.9)$ finally. In hamstring group, OAK scores were 73.9$({\pm}11.5)$ and 82.5$({\pm}12.9)$ respectively. There was no difference in stability checked by either $KT-1000^{TM}$ or stress view. Anterior tibial translation measured by $KT-1000^{TM}$ were 2.4$({\pm}1.8)$mm in BPTB and 2.3$({\pm}2.4)$mm in hamstring group. Anterior tibial translation in stress view were 2.8$({\pm}3.4)$mm in BPTB and 2.8$({\pm}2.5)$mm in hamstring group. There was no difference in tibial tunnel expansion but femoral tunnel was more enlarged in hamstring group than BPTB (P=0.03). Conclusion : As there was no difference in stability between two groups, it seems prudent to select either graft defend on such factors as anterior knee pain, skeletal maturity and cosmetic concern. Tunnel expansion seems not to affect stability, but further study is needed to confirm that decrease of which might improve stability.

Purpose: The purpose of this study was to evaluate the clinical outcomes and stability of anatomical single bundle anterior cruciate ligament reconstruction (SBACLR) with quadriceps tendon comparable to double bundle anterior cruciate ligament reconstruction (DBACLR). Materials and Methods: We retrospectively reviewed 28 consecutive patients (16 male, 12 female) who underwent SBACLR using quadriceps tendon from March 2009 (Group 1) and compared its clinical results to whom DBACLR with semitendinosus tendon for 53 patients (51 male, 2 female) from August. 2006 (Group 2). Mean age were 34.9 (range, 16-52) in Group 1 and 21.6 (range, 17-55) in Group 2. Mean follow up periods were 13.9 months (range, 12-20) in Group 1 and 36.2 months (range, 20-52) in Group 2. Lysholm score, International Knee Documentation Committee (IKDC) evaluation form and Tegner score were performed for evaluating the clinical outcome. Lachman test, pivot shift test and KT-1000 arthrometer (MEDmetric Corp., San Diego, CA, USA) were performed for stability. Results: There was no statistical significant difference between the two groups in terms of Lysholm score (Group 1: $85.9{\pm}2.6$, Group 2: $90.9{\pm}1.0$, P=0.226), IKDC score (P=0.345) and Tegner score (Group 1: $6.9{\pm}1.4$, Group 2: $7.1{\pm}1.3$, P=0.523). Nor was there statistical significance between the two groups in terms of KT-1000 arthrometer (Group 1: $1.5{\pm}1.1\;mm$, Group 2: $1.5{\pm}1.6\;mm$, P=0.457), Lachman test (P=0.547) and pivot shift test (P=0.073). Conclusion: Anatomical SBACLR with quadriceps tendon shows similar clinical outcomes and stability comparable to anatomical DBACLR with hamstring tendon.

Purpose: To compare the stability and clinical result after anterior cruciate ligament reconstructed knee after graft fixation using Intrafix in tibial tunnel with or without additional tibial post fixation. Materials and Methods: We analyzed 37 cases which were treated with four-strand hamstring tendon autograft during the period from May 2002 to January 2003. The grafts were fixed with Rigidfix system (Mitek Product, Johnson and Johnson, USA) in femur tunnel and Intrafix system (Mitek Product, Johnson and Johnson, USA) in tibial tunnel. After tibial fixation, additional tibial post fixation was done, which was determined by the serial case number prospectively. Patients were followed for average of fourteen months(range, thirteen to twenty-five months) At the time of final follow-up, patients were evaluated in terms of Lachman test, pivot shift test, Lysholm scores, IKDC (International Knee Documentation Committee) assessment, side-to-side KT-1000 maximum-manual arthrometer differences. Results: At last follow-up, Lysholm score was average 93.1(range: 65 to 98), IKDC assessment revealed that 26 cases had score of A, 10 cases had score of B and 1 case had score of C. The average maximum-manual KT-1000 arthrometer side ?to-side difference was 2.5 mm$(0{\sim}6mm)$. There was one case in which the Lachman test was graded as 2+ and four cases in which the Lachman test was graded as 1+ and the remaining thirty-two cases were normal by Lachman test. One case had a 2+ pivot-shift, and 2 cases had a 11 pivot-shift. The remaining 34 knees were normal on pivot -shift testing. The average maximum-manual KT-1000 arthrometer side-to-side difference was average 2.8 mm$(0{\sim}6mm)$ in Intrafix only group and average 2.2 mm$(0{\sim}4mm)$ in additional fixation group (P>0.05). Conclusion: Without additional tibial fixation, the stability of the anterior cruciate reconstructed knee with hamstring graft which was fixed with Intrafix was restored.
