  • As computer technology develops and this is applied to medical image field, three dimensional image reconstruction technology using computer simulation is utilized in various categories that include anatomical study and biomechanics study of human body. Especially orthopedic surgeons are able to investigate biomechanical function and be provided information for operations with this technology in terms of ligament reconstruction of knee. And this technology can be utilized in preparing preoperative planning and instructions and training. This review is about three dimensional image reconstruction technology which is utilized in ligament reconstruction of knee.

  • Ulnar collateral ligament injuries have been increasingly common in overhead throwing athletes. Ulnar collateral ligament reconstruction is the current gold standard for managing ulnar collateral ligament insufficiency, and numerous reconstruction techniques have been described. Although good clinical outcomes have been reported regarding return to sports, there are still several technical issues including exposure, graft selection and fixation, and ulnar nerve management. This review article summarizes a variety of surgical techniques of ulnar collateral ligament reconstructions and compares clinical outcomes and biomechanics.

  • This is a case of the core reamer breakage during anterior cruciate ligament reconstruction using bone-patellar tendon-bone autograft. A 19-year-old man with acute anterior cruciate ligament rupture had reconstruction surgery. During tunneling in the proximal tibia, the core reamer have been cracked open and broken. Rest of the procedure was performed routinely except the tibial sided fixation of bone block which was performed with larger interference screw than usual. The patient followed the accelerated rehabilitation program. The result was satisfactory at 2 years after surgery.

Distal Clavicle Tunnel Widening after Coracoclavicular Ligament Reconstruction with Semitendinous Tendon: A Case Report (반건양 건을 이용한 오구쇄골 인대 재건술후 발생한 원위부 쇄골 터널 확장: 증례 보고)

  • Distal clavicle tunnel widening was observed in coracoclavicular ligament reconstruction with semitendinous tendon autografts in a patient with acromioclavicular joint injury. Acromioclavicular joint separation, in a 44 years-old man was treated by coracoclavicular ligament reconstruction. We have performed x-ray evaluation on 2years 10months after surgery. The immediate postoperative tunnel size was measured 4.5mm in diameter. At postoperative 2years 10month the tunnel diameter was from 9.3 to 11.4mm. But the weightbearing clavicle view showed no significant acromioclavicular joint separation. Moreover the patient complained only minor intermittent shoulder discomfort.

  • Diffuse pigmented villonodular synovitis (PVNS) involving ankle joint needs complete mass excision and total synovectomy to reduce recurrence rate, while surrounding ligaments can be easily damaged. So the concurrent ligament reconstruction should be considered for post-excisional instability in subtalar joint as well as lateral ankle joint. We describe our experience in the management of a diffuse type PVNS, invades lateral talocrural joint extended to subtalar joint and introduce a new technique of all-in-one reconstruction for anterior talofibular,calcaneofibular and cervical ligament. Our new reconstruction technique applying modified Chrisman and Snook technique is useful in stabilization for deficiencies of the ligament complexafter PVNS excisionat lateral ankle and subtalar joint.

  • We performed lateral ankle ligament reconstructions using Achilles allograft on patients who had failed previous Brostrom repair. The bone plug is fixed with an interference screw into the calcaneus, the tendon graft is passed through a fibular tunnel, and then anchored into the talus with the biotenodesis screw. The graft is strong enough to maintain joint stability until graft incorporation and remodeling occurs. In patients with chronic failed lateral ankle instability requiring graft for ligament reconstruction, this technique allows anatomic reconstruction without the need to sacrifice autogenous peroneal tendons.

  • Background: The purpose of this study is to compare and analysis the changes in strength and endurance of the knee extensor muscles after Anterior cruciate ligament reconstruction. Methods: Twelve male subjects with ligament injury were seated on Biodex and the hip joint was flexed at 110°, and torso, lower extremities, and legs were fixed using Velcro. The resistance device was placed at a point 3cm above the ankle, and measurements were taken before and a surgery at 60°/sec and 180°/sec when the knee was maximally extended. The postures ingeniously combine forward-bending poses countered with backward-bending ones. Results: There was no significant difference in the comparison of muscle strength of 60°/sec and 180°/sec before surgery. But there was a significant difference after surgery. There was significant difference in muscle endurance both before and after surgery. There was a significant difference in the pre- and post- operative comparison values of muscle strength and endurance in isokinetic movements at 60°/sec and 180°/sec during knee extension on the injured side. Conclusion: For cruciate ligament tears, Orthopedic reconstruction is recommended. Correct alignment of the knee ligament after surgery can enhance the strength and endurance of the quadriceps femoris during knee extension rejuvenated.
