BACKGROUND: Double-bundle anterior cruciate ligament (ACL) reconstruction has demonstrated improved biomechanical properties and moderately better objective outcomes compared with single-bundle reconstructions. This could make an impact on the rerupture rate and reduce the risk of revisions in patients undergoing double-bundle ACL reconstruction compared with patients reconstructed with a traditional single-bundle technique. The National Knee Ligament Registers in Scandinavia provide information that can be used to evaluate the revision outcome after ACL reconstructions...

PURPOSE: After revision anterior cruciate ligament reconstruction (ACLR), the rate of return to the pre-injury type of sport (RTS type) is low and graft choice might be an important factor. The aim of this study was to determine whether there is a difference in outcome after revision ACLR using a patellar tendon allograft compared to an ipsilateral patellar tendon autograft. It was hypothesized that the rate of RTS type using an ipsilateral patellar tendon autograft will be superior to using patellar tendon allograft...

Various surgical techniques have been described for the fixation of acromioclavicular (AC) dislocations. However, recurrent dislocation is one of the main complications associated with the majority of these techniques. We report a case of postoperative AC joint redislocation. In order to overcome recurrent dislocation after revision surgery, a reconstruction of the conoid and trapezoid ligament with the use of a free tendon graft in combination with a FiberTape was provided within a novel surgical technique...

Electrical burn injury causing bilateral patellar ligament destruction leading to complete loss of knee extension is a very rare injury. In such situation, surgical repair or reconstruction of the patellar ligament becomes necessary to restore knee functions. Here, we present such a case of an 8-year-old boy, whose both patellar ligaments were destroyed throughout its length due to high-voltage electrical injury. His left knee joint cavity was exposed and grossly infected, but the right knee joint cavity was apparently intact...

Anterior cruciate ligament (ACL) injuries are one of the most well-known orthopaedic injuries and are treated with one of the most common orthopaedic procedures performed in the United States. This surgical procedure, ACL reconstruction, is successful at restoring the gross stability of the knee. However, the outcomes of ACL reconstruction can be limited by short and long term complications, including muscle weakness, graft rupture and premature osteoarthritis. Thus, new methods of treating this injury are being explored...

PURPOSE: The availability of tendon grafts is an important consideration for successful upper extremity reconstructive surgery, including flexor or extensor tendon reconstructions, tendon transfers, and ligament reconstructions. Graft selection is based on availability, expendability, ease of harvest, and length. Given variations in patient height and extremity length, existing average values may provide suboptimal insight into actual tendon lengths available. The purpose of this study is, therefore, to pursue a method of estimating available donor tendon lengths based on easily measured anatomical surface landmarks...

PURPOSE: In adults, reconstruction of the medial patellofemoral ligament (MPFL) has shown good results. Treatment for recurrent patellar instability in children and adolescents with open growth plates, however, requires alternative MPFL reconstruction techniques. This study presents the outcomes of a minimally invasive technique for anatomic reconstruction of the MPFL in children using a pedicled superficial quadriceps tendon graft, hardware-free patellar graft attachment, and anatomic femoral fixation that spares the distal femoral physis...

Primary anterior cruciate ligament (ACL) reconstruction is a common orthopaedic procedure. A graft failure rate of 5% to 10% after primary ACL reconstruction has resulted in an increased need for revision ACL reconstruction. ACL reconstruction failure etiologies include trauma, technical errors, and biologic factors. Based on the current literature, the outcomes of revision ACL reconstruction are clearly inferior compared with those of primary reconstruction. A thorough patient evaluation, including surgical history, a physical examination, and imaging studies, is crucial in the assessment of a failed ACL reconstruction...

Periodontal disease is categorized by the destruction of periodontal tissues. Over the years, there have been several clinical techniques and material options that been investigated for periodontal defect repair/regeneration. The development of improved biomaterials for periodontal tissue engineering has significantly improved the available treatment options and their clinical results. Bone replacement graft materials, barrier membranes, various growth factors and combination of these have been used. The available bone tissue replacement materials commonly used include autografts, allografts, xenografts and alloplasts...
