Chronic extensor hallucis longus (EHL) tendon rupture is relatively rare, but in such cases, surgical repair is necessary to prevent hallux dysfunction. To the best of our knowledge, reconstruction of chronic EHL rupture using a split tibialis anterior tendon autograft has not been previously reported. Here we present a case of spontaneous EHL tendon rupture with a 5 cm gap in a healthy 57-year-old woman. At the 1-year follow-up evaluation, hallux function was restored, and the patient was well satisfied with results.

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.

Purpose: The purpose of this study is to compare the clinical results of ACL reconstruction between two groups using hamstring tendon autograft and tibialis anterior tendon allograft. Materials and Methods: Between January 2006 and June 2007, we analyzed 68 cases of ACL reconstruction, 32 cases using hamstring tendon autograft and 36 cases using tibialis anterior tendon allograft, with a minimum follow-up of 24 months. For the clinical evaluation, we evaluated the Lysholm score, anterior laxity by Telos device and KT-2000 arthrometer. Results: The mean diameter of graft were 8.0 mm (7.0~9.0 mm) in autograft group and 9.1 mm (8.0~10.0 mm) in allograft group. In all cases, the range of motion was above 135 degrees. The average side to side difference in Telos stress test decreased from $7.3{\pm}1.0$ mm to $2.4{\pm}1.1$ mm in autograft group and from $7.4{\pm}1.2$ mm to $2.3{\pm}1.3$ mm in allograft group. The average Lysholm knee score improved from $72.6{\pm}3.4$ to $92.3{\pm}3.5$ in autograft group and from $72.3{\pm}3.5$ to $91.6{\pm}3.3$ in allograft group. There was no significant difference between two groups in clinical results. Conclusion: Both hamstring tendon autograft and tibialis anterior tendon allograft groups showed satisfactory clinical results, with no significant difference in outcomes between the groups. We suggest that both hamstring tendon autograft and tibialis anterior tendon allograft will be considered as acceptable graft for anterior cruciate ligament reconstruction.

Purpose: This study is to compare the clinical results of ACL reconstruction between three groups using hamstring tendon autograft, mixed and tibialis tendon allograft. Materials and Methods: Between August 2003 and August 2008, we analyzed 169 cases of ACL reconstruction, 66 cases used hamstring tendon autograft, 42 cases used mixed graft and 61 cases used tibialis tendon allograft, with a minimum follow-up of 12 months. For the clinical evaluation, we evaluated the Lysholm score, Telos stress test device and IKDC score. Results: The average side to side difference in Telos stress test decreased from $7.5{\pm}1.0$ mm to $1.6{\pm}1.0$ mm in autograft group, from $7.6{\pm}1.1$ mm to $1.4{\pm}1.1$ mm in mixed graft group and from $7.4{\pm}1.3$ mm to $2.5{\pm}1.3$ mm in allograft group. The average Lysholm knee score improved from 58.6 to 92.3 in autograft group, from 60.6 to 92.6 in mixed graft group and from 55.3 to 91.5 in allograft group. There was no significant difference between three groups in clinical results. At second look arthroscopy, tension of ligament and synovial coverage were good result in autograft and mixed graft than allograft group. Conclusion: All hamstring tendon autograft, mixed graft and tibialis tendon allograft groups showed satisfactory clinical results, with no significant difference in outcomes between the groups. Both hamstring tendon autograft and mixed graft showed good synovial coverage in second look arthroscopy. So mixed graft will be considered as good alternative in case of shorter or thin harvested hamstring tendon.

Purpose : The purpose of this study is to compare the clinical and radiologic results of the anterior cruciate ligament(ACL) reconstruction using bone-patellar tendon-bone unit with doubled semitendinosus and gracilis tendons. Materias and Methods : Clinical results of ACL reconstructions which were performed in 47 patients using doubled semitendinosus and gracilis were compared with those performed in 45 patients using bone-patellar tendon-bone autograft. There were no differences in preoperative parameters(age, sex, instability). Average follow-up period were 17 months and 19 months each. Results : There were no significant differences between two groups in functional results (Lysholm knee score), degree of laxity and range of motion at final follow-up. However, the parapatellar complication, especially anterior knee pain after long distance walking or exercise and quadriceps weakness less occurred in hamstring tendon group than in bone-patellar tendon-bone group. Conclusion : Although there were no significant differences in clinical results of ACL reconstruction using bone-patellar tendon-bone autograft and doubled semitendinosus and gacilis, parapateller complications occurred more in the bone-patellar tendon-bone autograft group than in the doubled semitendinosus and gracilis group. It is thought that the careful selection of patient, achivement of skillful technique and active rehabilitation are important to prevent the parapatellar complications.

The Hamstring autograft and the bone patellar bone tendon autograft have been widely used for anterior cruciate ligament reconstruction. In recent years, use of hamstring autograft for ACL reconstrution has been increased. The reason seems to be the advantages of the hamstring tendon such as high ultimate tensile load, low donor site morbidity and development of graft fixation method. These theoretical advantages have been increased as studies have shown that hamstring tendons actually regenerate after harvesting for ACL reconstruction. However, the concerns have arisen regarding the disadvantages of hamstring harvest, which were weakness of tibial internal rotation, the loss of flexion strength. The flexion strength loss has been controversial, therefore it needs to study whether restoration of flexion strength after hamstring regeneration is or not. In this study, we reviewed the current research of concerns on the advantage and disadvantage of hamstring tendon autograft and the hamstring regeneration. Furthermore, we compared the earlier studies and experiences regarding Hamstring regeneration with our research.

The incidence of anterior cruciate ligament tears is increasing as a result of the increasing participation of individuals of all ages in high-risk sports. Endoscopic anterior cruciate ligament reconstruction using autogenous central third bone-patellar tendon-bone graft is the most commonly used method. With regard to BPTB graft as the go]d standard in ACL reconstruction, there are no data that refute this claim to date. Author reviewed the biomechanical properties, donor site morbidity and selection of the bone-patellar tendon-bone graft and described the surgical technique of endoscopic ACL reconstruction using BPTB autograft.

Purpose: To evaluate status of reconstructed ACL and changes around graft through second-look arthroscopy after arthroscopic reconstruction of the ACL with autograft tendons. Material and Methods: Between Jun. 2003 and Feb. 2007, the second look arthroscopy was performed on 22 cases. Second-look arthroscopy was conducted on average 15.1 $(7\sim31)$ months after reconstruction. 15 cases received hamstring tendon autograft, 7 cases received bone-patellar tendonbone autograft. We measured graft tension using displacement by probing, synovial coverage by visual analysis at second-look arthroscopy The assay in Lysholm score, Lachmann test and KT-2000 arthrometer were evaluated status of reconstructed ACL. Results: The hamstring tendon group showed normal tension in 11 cases and lax tension in 4 cases. The patellar tendon group showed normal tension in 3 cases, lax tension in 2 cases and partial tear in 2 cases. In the hamstring tendon group, synovial coverage was good in 11 cases, half in 3 cases and pale in 1 case, and the bone-patellar tendon-bone group was good in 4 cases and half in 3 cases. The patellar tendon group was superior to the hamstring tendon group in Lysholm score (p<0.05), but insignificance difference in KT-2000 arthrometer results statistically. Conclusion: The hamstring tendon group was superior to the bone-patellar tendon-bone group in second-look arthroscopy after ACL reconstruction with autograft tendons results, but long term follow up will be necessary to further evaluated.

Background: Surgical management of a massive rotator cuff tear (RCT) is always challenging. This study describes the clinical and radiological outcomes of patients who underwent bridging grafts using a plantaris tendon for an irreparable RCT. Methods: Thirteen patients with a massive RCT were treated with arthroscopic interposition of a folded plantaris tendon autograft between June 2017 and January 2020. For clinical evaluation, a visual analog scale (VAS), American Shoulder and Elbow Surgeons (ASES) score, Disabilities of the Arm, Shoulder, and Hand (DASH) score, Constant-Murley score, and range of motion values were collected. For radiographic evaluation, standardized magnetic resonance imaging and ultrasonography were performed to check the integrity of the interposed tendon. Results: A statistically significant improvement at the final follow-up was evident in scores for the VAS (-3.0, P=0.003), ASES (24.9, P=0.002), D ASH (-20.6, P=0.001), and Constant-Murley values (14.2, P=0.010). In addition, significant improvement was shown in postoperative flexion (17.3°, P=0.026) and external rotation (27.7°, P<0.001). In postoperative radiologic evaluations, the interposed tendons were intact at the last examination in 12 of the 13 patients. No complications related to donor sites were reported. Conclusions: An arthroscopic bridging graft for irreparable RCTs using a modified Mason-Allen stitch and a plantaris autograft resulted in improved short-term radiological and clinical outcomes. Graft integrity was maintained for up to 2 years in most patients. Level of evidence: IV.
