  • Purpose : To compare the functional evaluation with the posterior translation after arthroscopic PCL reconstruction in isolated and combined PCL-deficient knees. Materials and Methods : We retrospectively evaluated 45 patients with PCL-deficient knees who were treated by arthroscopic PCL reconstruction using Achilles tendon allograft from June 1994 to June 2000. The differences of posterior translation were measured with posterior stress lateral radiographs and KT-2000 arthrometer. The functional results were evaluated using the Lysholm knee score and IKDC evaluation form. Results : Preoperative mean side to side differences of the posterior translation were 11.83 mm in isolated PCL-deficient knees and 12.7 mm in combined PCL-deficient knees respectively. At the last follow-up in isolated and combined PCL-deficient knees, the mean radiographic side to side differences of the posterior translation were 6.38 mm and 6.7 mm, the average corrected 20 Ib posterior displacements using KT-2000 arthrometer were 3.5 mm and 4.1 mm, the mean Lysholm score were 87.4 and 81.2, the grade A and B of IKDC evaluation form were 16 cases $(88.9\%)$ and 23 cases $(85.2\%)$, respectively. Conclusion : The functional results had no relationship with the degree of posterior translation after arthroscopic PCL reconstruction. Tendency of posterior translation may be influenced by associated injury of the knee.

  • Purpose : The purpose of this study was to assess the clinical outcomes and radiological changes of arthroscopic augmentation with synthetic polyester ligament for posterior cruciate ligament injury Materials and Methods : The assessment was made among 60 patients who underwent arthroscopic augmentation with synthetic polyester ligament (ABC ligament, Surgicraft, U.K.) into the substance of ruptured PCL proper under the arthroscopic control from January, 1990 to January, 1996 and whose follow-up period was more than 5 years (average 7.8 years). The results were analyzed by using the posterior stress radiographs by Telos stress device, KT-2000 arthrometer and the clinical assessment by using Lysholm knee score. Results : The average difference of posterior displacement on stress radiographs were 13.2 mm preperatively and 3.6 mm at last follow up. Both knee showed minimal difference on KT-2000 arthrometer (0.7 mm on 20 lb) at the last follow-up. The mean Lysholm knee score was 49.2 preoperatively and improved to 84.3 post-operatively. Conclusion : Authors observed that long-term results of arthroscopic augmentation with synthetic polyester ligament for PCL injury were similar with those using human allograft. Taking these results into consideration, the synthetic polyester ligament is assumed to be a method of treatment of the PCL injury.

  • Purpose: The purpose of the study was to evaluate the usefulness and the stability of the superficial medial collateral ligament (MCL) release in posterior medial meniscus root repair. Materials and Methods: We compared 20 patients who underwent posterior medial meniscus root repair with superficial MCL preserved (PM) and 32 patients who underwent posterior medial meniscus root repair combined with superficial MCL release (RM) from April 2006 to September 2010. We excluded the patients combined with other surgery. To evaluate the postoperative valgus instability in RM group, we examined direct tenderness on MCL insertion, the subjective feeling of instability and valgus stress test at 3 months and 1 year follow-up. We compared the tourniquet time between PM group and RM group, and the clinical results were assessed by Lysholm score and International Knee Documentation Committee (IKDC) for the usefulness. Results: All patients had no clinically significant complication related to the superficial MCL release. Three months and 1 year follow-up, there were no positive tenderness test, no subjective symptoms and no significant increase of valgus instability although 5 patients examined grade I valgus instability. The mean tourniquet time was $41.3{\pm}12.7$ minutes in RM group and $53.5{\pm}13.6$ minutes in PM group. There was a significant difference in the tourniquet time between the two groups (P<0.05). Average Lysholm score was $56.8{\pm}5.5$ (range, 44-70) preoperatively and $85.1{\pm}5.8$ (range, 77-94) postoperatively in PM group, and was $56.2{\pm}5.4$ (range, 45-67) preoperatively and $87.4{\pm}3.9$ (range, 82-95) postoperatively in RM group (P<0.001). No significant difference of Lysholm score was found in both groups (P<0.05). Average IKDC scores was $42.6{\pm}3.9$ (range, 30-53) preoperatively and $77.2{\pm}6.3$ (range, 68-92) postoperatively in PM group, and was $42.7{\pm}5.7$ (range, 30-53) preoperatively and $89.6{\pm}2.9$ (range, 84-95) postoperatively in RM group (P<0.05). There was also no significant difference of IKDC score in both groups (P<0.05). Conclusion: The superficial MCL release in posterior medial meniscus root repair is useful to gain a wide surgical field and reduces the tourniquet time and does not lead to postoperative valgus instability. It can be considered clinically useful and safe procedure in medial meniscus posterior root repair.

  • Background: The purpose of this study was to compare the clinical and radiological results of 2 different tibial fixations performed using bioabsorbable screws with added hydroxyapatite (HA) and pure poly-L-lactic acid (PLLA) screws in anterior cruciate ligament (ACL) reconstruction. Methods: A total of 394 patients who underwent arthroscopic ACL reconstruction between March 2009 and June 2012 were retrospectively reviewed. Of those, 172 patients who took the radiological and clinical evaluations at more than 2 years after surgery were enrolled and divided into 2 groups: PLLA group (n = 86) and PLLA-HA group (n = 86). Both groups were assessed by means of the Lysholm score, International Knee Documentation Committee (IKDC) subjective knee score, and Tegner activity score. Stability was evaluated using the KT-2000 arthrometer. Magnetic resonance imaging was performed to evaluate tibial tunnel widening, screw resorption, osteoingeration, and foreign body reactions. Results: The PLLA-HA group showed significant reduction in the extent of tibial tunnel widening and foreign body reactions and significant increase in screw resorption compared to the pure PLLA group (p < 0.001 for both). In contrast, postoperative Lysholm score, Tegner activity score, IKDC score, and side-to-side difference on the KT-2000 arthrometer showed no significant differences between groups (p = 0.478, p = 0.906, p = 0.362, and p = 0.078, respectively). The PLLA group showed more significant widening in the proximal tibial tunnel than the PLLA-HA group (p = 0.001). In the correlation analysis, proximal tibial tunnel widening revealed a positive correlation with knee laxity (r = 0.866) and a negative correlation with Lysholm score (r = -0.753) (p < 0.01 for both). Conclusions: The HA added PLLA screws would be advantageous for tibial graft fixation by reducing tibial tunnel widening, improving osteointegration, and lowering foreign body reactions. Even though no clinically significant differences were noted between the pure PLLA group and PLLA-HA group, widening of the proximal area of the tibial tunnel showed a tendency to increase knee laxity measured using the KT-2000 arthrometer.

  • Purpose: To evaluate clinical results of autologous osteochondral graft in osteochondral lesions of the talus. Materials and Methods: Twenty feet in twenty patients underwent osteochondral autologous transfer in the osteochondral lesions of the talus. Sixteen were men and four were women. The mean age was 40.8 years old. The mean follow up was 2 years 9 months. Eighteen cases were medial, one case was lateral and one case was both, respectively. The average duration of symptom was 4 years 3 months. AOFAS ankle/hindfoot score (AOFAS score), visual analogue scale (VAS), Lysholm knee score were evaluated preoperatively and at the final follow up. Results: Postoperative AOFAS score was 87.3 (range, 69-100), which was significantly improved from preoperative AOFAS score of 62.0 (p=0.000). Postoperative VAS was 2.9 (range, 0-7), which was significantly improved from preoperative VAS of 7.5 (p=0.000). Postoperative Lysholm knee score was 92.4 (range, 80-100). All osteotomy of medial malleolus was united by the 4th month after surgery. Postoperative VAS was conversely correlated with the follow up period (p=0.024). There was no complications associated with surgery. Conclusion: Autologous osteochondral grafts in osteochondral lesion of the talus demonstrated excellent results with a short-term follow up.

  • Purpose: This study presents clinical results of anterior cruciate ligament(ACL) augmentation using autogenous two-strand semitendinosus tendon in the treatment of partial ACL tears with preservation of residual portion. Materials and Methods: From January 2004 to June 2006, twenty two patients who had an ACL injury underwent ACL augmentation using autogenous two-strand semitendinosus tendon were enrolled in this study. We evaluated the clinical results with regard to clinical findings(range of motion, Lachman test, pivot shift test), standard knee scales(Lysholm, Modified Feagin Scoring System), and KT-1000 arthrometer testing. Results: At minimum one year postoperatively, there was no limitation of range of motion. Lachman and pivot shift tests were negative in all knees. On instrumented anterior laxity test by KT-1000 arthrometer, mean side to side difference was improved from 4.6mm preoperatively to 1.7mm postoperatively. Average Lysholm score was improved from 70 to 92. Ninety one percent of cases were rated as good or excellent in Modified Feagin Scoring System. Conclusion: Augmentation using autogenous two-strand semitendinosus tendon with preservation of residual portion of the ACL seems to be an acceptable method for restoring knee stability and proprioceptive function.

  • 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.

  • Background: We analyze the functional evaluation, posterior stability after surgery of acute injuries in the femoral detachment and tibial avulsion fracture of posterior cruciate ligament. Materials and Methods: Twenty two patients who underwent primary repair were followed more than one year after operation (mean follow-up 33.7 months). The patients were evaluated with KT 2000 arthrometer and posterior stress test for posterior stability. Lysholm knee score was used for knee function. Results: Lysholm score revealed 85.3 in femoral detachment group and 91.1 in tibial avulsion fracture group (P<0.05). Posterior displacement of the posterior stress test showed 17.2 mm at initial injury and 8.6 mm at last follow up in femoral detachment group, 16.8 mm at initial injury and 7.1 mm at last follow up in tibial avulsion fracture group. There revealed the tendency of the improved posterior stability of the tibial avulsion group compared with femoral detachment group, but there showed no statistical significance in KT 2000 arthrometer and posterior stress x-ray. Conclusion: Functional results of tibial avulsion fracture group revealed the better outcome compared with femoral detachment group, but the degree of posterior stability in tibial avulsion fracture group showed no statistical significance in posterior stability.

  • Purpose: To evaluate and compare the functional results, activity status, and anterior stability between conservative group with partial ACL injury and reconstruction group with bone-patellar ten-don-bone autograft in ACL total rupture. Materials and Methods: Thirty-eight patients with ACL injury were diagnosed and treated with arthroscopy and followed for more than two years. The number of patients with partial injury was 12(mean age; 38.3) and reconstruction group was 26 (mean age; 25.3). Objective stability was estimated under anterior loading of 15 lb and 20 lb by KT-2000 Arthrometer (MED metric, USA). Functional evaluation using Lysholm score and Tegner activity score were performed. Results: Average functional score of Lysholm was 88.5 in partial injury group and 89.3 in reconstruction group. Average score of Tegner was 5.3 in partial injury group and 5.1 in reconstruction group(P<0.05).Average anterior displacement compared with normal side. Under loading of 20lb, 1.7$\pm$4.3 mm in partial injury group, 2.3$\pm$1.9 mm in reconstruction group were anterior displaced (P<0.05). Under loading of 15lb, 1.2$\pm$1.0 mm in partial injury group, 1.4$\pm$1.5 mm in reconstruction group were dis-placed (P<0.05). There were giving way, effusion, instability and anterior knee pain in complication. Giving way was the frequent complication in the partial injury group. Conclusions: Clinical results of both group were similar. Functional evaluation of Lysholm was good and status of Tegner activity was maintained to physical fitness activites (jogging, regular bik-ing) in both groups on average. The results of conservative treatment for the partial ACL injury (less than 50$\%$) was satisfactory and equivalent to that of reconstructive treatment for the total ACL injury.
