Purpose: To evaluate the outcome of arthroscopic posterior cruciate ligament (PCL) augmentation using an autogenous hamstring tendon graft and the posterior-posterior triangulation technique with preservation of ligament remnant or elongated ligament. Materials and Methods: From January 2002 to December 2009, we performed PCL augmentation using an autogenous hamstring tendon graft and the posterior-posterior triangulation technique in 32 patients. The mean age was 35.2 years. Twenty two cases were male and 10 cases were female. Average follow-up period was 5 years and 5 months (range: 2-7.9). Subjective and objective parameters were utilized in analyses, such as the mean range of motion, post. drawer test, Lysholm knee score, Tegner activity score, International Knee Documentation Cominittee (IKDC) grade, and second look arthroscopic examination. Results: At last follow up posterior displacement by the Telos stress test decreased from $10.8{\pm}5.1\;mm$ to $2.8{\pm}3.7\;mm$ (p<0.05). The final Lysholm knee score improved from $60.4{\pm}5.8$ to $84.6{\pm}4.8$. Tegner activity score improved from 3.2 to 4.8. The final IKDC grade was A in 18, B in 11, C in 3. Postoperative Lysholm knee score, IKDC grades, Tegner activity scale, and posterior displacement demonstrated statistically significant improvement compared to the preoperative state (p<0.05). Conclusion: Arthroscopic PCL reconstruction using an autogenous hamstring tendon with preservation of ligament remnant showed a good clinical results and posterior stability.

A 34-year-old man with ACL total rupture due to slip down injury, had received ACL reconstruction using autogenous hamstrings tendon with cross-pin femoral fixation. Postoperative course was as usual. But postoperative 3 months later, he complained posterolateral knee pain, recurrent effusion and mild instability. He was managed repeatitive aspiration and nonsteroid antiinflammatory drugs but was failed to relieve symptoms & signs. In CT scans, perforation of posteromedial femoral cortex of lateral femoral condyle was found. In second look arthroscopy, two pieces of broken femoral cross pin were found in between tibiofemoral Joint which was badly injured cartilage. We considered malposition of pins was the main cause of failure. We propose that femoral tunnel must be made more acute angle and femoral cross-pin guide must be positioned more external rotation 10-20 degree than transepicondylar axis made confirm the cross-pin tunnel position in order to avoid posterior cortex perforation and early failure.

There are many controversies in managing fresh substance tear of PCL. Conservative treatment of partial tear is generalby accepted idea, and less than 10mm posterior instability is known to be acceptable in terms of funtion. More than 10mm posterior instability and complete fresh tear of the ligament are regarded as candidates of reconstruction of the ligament. However, many authors believe that posterior instability may be a cause of early osteoarthritis in the long run. Author described the rationale and the technique of arthroscopic primary repair of the PCL in case of proximal and mid 1/3 substance tear. Postoperative rehabilitation program and their rationale were also described.

Trans-posterior septal posterior arthroscopic portals are useful in performing arthroscopic diagnosis and treatment of the lesions located in posterior aspect of knee joints. Except inferior surface of posterior horn of lateral meniscus, we easily observed entire lateral compartment, especially inferior surface of anterior horn and lateral tibial condyle by figure of 4 position through posteromedial trans-posterior septal arthroscopic portal. And it was possible to obtain visual field from posterior aspect and we could use anteromedial and anterolateral portals for instrumentation without clouding. So, this procedure may be useful in performing surgery of lateral compartment especially, anterior aspect in the knee joints.

Purpose : The purpose of this study was to evaluate the clinical results of fresh-frozen achilles allograft PCL reconstruction. Materials and Methods : 34 patients(35 cases) who was reconstructed PCL arthroscopically using achilles allograft were analyzed subjective and objective parameters, Telos stress arthrometer and Modified Feagin Scoring System. The average age was 36.2 years old($16\~57$ year) and average follow up period was 18.5 months($12\~27$ months). Result : The mean Lysholm Knee Scoring was improved from 47.5 to 87.4. Posterior translation by Telos arthrometer decreased to 2.3mm from 7.1mm. The modified Feagin scoring system showed 32 cases$(91.5\%)$ with excellent and good result. Conclusion : Clinical results of PCL reconstruction by Achilles allograft revealed good result as to scales. Achilles allograft provided enough initial tension with length and minimized the complication of using autograft. Therefore achilles fresh-frozen allograft in PCL reconstruction is a good substitute material for autograft.

Purpose : To report a short-term clinical results and technical method of thermal shrinkage with radiofrequency device for anterior and posterior cruciate ligament laxity which is not suitable to indications of reconstructive surgery. Materials and Methods : Nine cases of anterior cruciate ligament injuries (ACL), 5 cases of posterior cruciate ligament (PCL) injuries and 3 cases of combined anterior and posterior cruciate ligament injuries, in which the condition is not indicated as reconstructive surgery, are investigated. The follow-up period averaged 6 months. Results : Instability in living activity, limping and pain were improved with excellent results. But, posterior cruciate ligament thermal shrinkage revealed as recurrent knee laxity progressively Conclusions : The result of thermal shrinkage for partial tear of cruciated ligament was excellent. We believe this procedure is applicable to partial tear of the ACL or PCL which reconstructive surgery is not indicated. Long-term follow-up results were needed.

Purpose: The purpose of this study was to analyze the effectiveness of local steroid injection for infraspinatus under ultrasonographic guidance in patients with posterior shoulder pain during horizontal adduction test. Materials and Methods: Twenty one cases of patients, from May 2013 to May 2014, showed positive horizontal adduction test were retrospectively analyzed. We performed ultrasonography-guided infraspinatus injection using steroid to these patients in the outpatient clinics. We evalulated results for visual analogue score (VAS) for pain, UCLA score for these patients before injection, following 3 months and 6 months after injection. Results: After ultrasonography-guided infraspinatus injection using steroid, there were clinically significant improvements in VAS and UCLA score at 3 month's follow-up period (p<0.05). But there were no significant differences in VAS and UCLA score between 3 months and 6 months (p>0.05). Fourteen of 21 (67%) cases showed much improved and improved satisfaction. Respectively, seven of 21 (33%) cases showed not improved and aggravation satisfaction. Conclusion: Ultrasonography-guided infraspinatus injection using steroid is an effective treatment method for the patients with exacerbated posterior shoulder pain during horizontal adduction test.

Purpose : The importance of meniscal repair is well recognized. But transeciton of the posterior horn of the medial meniscus at the posterior tibial attachment is rarely documented and known irreparable. We experienced 9 cases of transection, and present clinical features and pull out suture technique. Methods and Materials : There were 9cases of transection of the posterior horn of medial meniscus from September 1998 to July 1999 in our hospital. Age was 59.3 years in average and ranged from 38 to 70years. Clinical features and MRI made diagnosis in all cases. We confirmed the diagnosis with arthroscopy and repaired the transection with pullout suture technique. Clinical features : Transection of the posterior horn of the medial meniscus at the posterior tibia attachment occurred frequently in middle aged people. They complained posterior knee pain, but they have no history of definitive trauma. Characteristically they had difficulty in full flexion of the knee and in having a squatting position. MRI is very important in diagnosis of transection, especially in coronal view, there is separation of the posterior horn of the meniscus from the posterior tibial attachment. Surgical technique : Pullout suture technique includes debridement of fibrous or scar tissue, exposure of the subchondral bone of the posterior tibial attachment site, suture the transected end of the meniscus with PDS suture, bone tunnel formation from the anteromedial aspect of the proximal tibia, insertion of wire loop through the tibia tunnel, pull the PDS suture through the tibia tunnel out of the joint and stabilize the PDS with post-tie technique to the proximal tibia. Conclusion : Transection of the posterior horn of the medial meniscus at the posterior tibial attachment is not common clinically and rarely documented. Clinical features and MRI are very important in diagnosis of this type tear. Arthroscopic pullout sutures is useful for treatment of this type tear of the meniscus.
