Simultaneous bilateral hip joint imaging at 7 Tesla using fast transmit B1 shimming methods and multichannel transmission – a feasibility study

NMR in Biomedicine — Tue, 07 Feb 2012 05:00:00 +0100

The objective of this study was to demonstrate the feasibility of simultaneous bilateral hip imaging at 7 Tesla. Hip joint MRI becomes clinically critical since recent advances have made hip arthroscopy an efficacious approach to treat a variety of early hip diseases. The success of these treatments requires a reliable and accurate diagnosis of intraarticular abnormalities at an early stage. Articular cartilage assessment is especially important to guide surgical decisions but is difficult to achieve with current MR methods. Because of gains in tissue contrast and spatial resolution reported at ultra high magnetic fields, there are strong expectations that imaging the hip joint at 7 Tesla will improve diagnostic accuracy. Furthermore, there is growing evidence that the majority of these hi...

The reharvested patellar tendon has the potential for ligamentization when used for anterior cruciate ligament revision surgery

Knee Surgery, Sports Traumatology, Arthroscopy — Mon, 06 Feb 2012 19:34:15 +0100

Conclusions The clinical outcome 10 years after ACL revision surgery was poor in these four patients. In contrast, the reharvested patellar tendon appeared close to normal on MRI, and the second-look arthroscopy with the concomitant histological findings revealed that the grafts were viable 3 years after revision. Therefore, the reharvested patellar tendon seems to have the potential for ligamentization when used for ACL revision surgery. Level of evidence Case series, Level IV.

MRI and arthroscopy correlations of the hip: a case-based approach.

Pain Physician — Sun, 05 Feb 2012 17:36:02 +0100

Authors: McCall DA, Safran MR Abstract Disorders of the hip joint can be physically disabling for the patient and a diagnostic challenge for the physician. Advances in imaging the hip with MRI can help the physician determine a more specific diagnosis for patients with acute or chronic hip pain. MRI and particularly magnetic resonance arthrography have helped raised awareness of nonarthritic hip problems and have made the diagnosis of hip problems much easier. Intra-articular and extra-articular processes can be evaluated with MRI; multiple sequences are available to increase the sensitivity and specificity for detecting specific pathology around the hip. Because the hip is a deep joint within a large soft-tissue envelope, MRI more precisely delineates the sources of hip pain by ev...

A Magnetic Resonance Imaging Study of 100 Cases of Arthroscopic Acromioplasty

The American Journal of Sports Medicine — Thu, 02 Feb 2012 05:00:00 +0100

Conclusion: Even with a standard posterior cutting block technique during acromioplasty, 23% of patients still showed a hooked acromion after arthroscopic acromioplasty. Using the signs of coracoacromial ligament impingement as an indication for acromioplasty might lead to hooked acromions postoperatively, which were nonhooked acromions preoperatively. However, the retear rate showed no difference according to the postoperative acromial shape. (Source: The American Journal of Sports Medicine)

Comparison of Inside-Out and All-Inside Techniques for the Repair of Isolated Meniscal Tears: A Systematic Review

The American Journal of Sports Medicine — Thu, 02 Feb 2012 05:00:00 +0100

Conclusion: There are no differences in clinical failure rate or subjective outcome between inside-out and all-inside meniscus repair techniques. Complications are associated with both techniques. More nerve symptoms are associated with the inside-out repair and more implant-related complications are associated with the all-inside technique. Clinical Relevance: Rates of structural healing and complications are comparable for inside-out and all-inside repair techniques for isolated meniscal injury. Differences in observed healing rates after meniscal repair may be more dependent on tear pattern and associated anterior cruciate ligament reconstruction rather than an inside-out versus all-inside surgical approach.

Wedge volume and osteotomy surface depend on surgical technique for high tibial osteotomy

Knee Surgery, Sports Traumatology, Arthroscopy — Tue, 31 Jan 2012 16:46:56 +0100

Conclusion Bone geometry following HTO suggests that the biplanar open-wedge techniques simultaneously create smaller wedge volumes and larger bone surface areas compared to the uniplanar open-wedge techniques. The relatively neglected closed-wedge technique still offers in theory the best healing potential, characterized by an almost absent wedge volume and a large bone-to-bone contact area. Although this idealized geometric view on bony geometry excludes all biologic factors that influence bone healing, the current data suggest a general rule for the applied standard osteotomy techniques and all of their surgical modifications: reducing the amount of slow gap healing and simultaneously increasing the area of faster contact healing may be beneficial for osteotomy healing....

Functional knee brace use effect on peak vertical ground reaction forces during drop jump landing

The functions of the fibre bundles of the anterior cruciate ligament in anterior drawer, rotational laxity and the pivot shift

Knee Surgery, Sports Traumatology, Arthroscopy — Wed, 25 Jan 2012 18:04:27 +0100

Abstract This paper reviews the functional anatomy of the anterior cruciate ligament (ACL), which has a parallel array of collagen fascicles that have usually been divided into two ‘fibre bundles’: anteromedial (AM) and posterolateral (PL), according to their tibial attachment sites. The PL bundle has shorter fibres, and so it is subjected to greater tensile strains than the AM bundle when the whole ACL is stretched; its oblique orientation in the coronal plane imbues it with greater ability to resist tibial rotation than the more vertical AM fibre bundle. Most studies have found that the AM bundle is close to isometric when the knee flexes, while the PL bundle slackens approximately 6 mm. There is little evidence of significant fibre bundle elongation in response...

Two-stage revision of septic knee prosthesis with articulating knee spacers yields better infection eradication rate than one-stage or two-stage revision with static spacers

Knee Surgery, Sports Traumatology, Arthroscopy — Tue, 24 Jan 2012 07:34:46 +0100

Conclusions The methodological limitations of this study and the heterogeneous material in the studies reviewed notwithstanding, this systematic review shows that, on average, a two-stage procedure is associated with a higher rate of eradication of infection than one-stage revision for septic knee prosthesis and that articulating spacers are associated with a lower recurrence of infection than static spacers at a comparable mean duration of follow-up.

Accuracy of magnetic resonance imaging, magnetic resonance arthrography and computed tomography for the detection of chondral lesions of the knee

Knee Surgery, Sports Traumatology, Arthroscopy — Tue, 24 Jan 2012 07:34:46 +0100

Conclusions Specialist radiological imaging is specific for cartilage disease in the knee but has poorer sensitivity to determine the therapeutic options in this population. Due to this limitation, there remains little indication to replace the ‘gold-standard’ arthroscopic investigation with MRI, MRA or CTA for the assessment of adults with chondral lesions of the knee.

Rotator cuff: biology and current arthroscopic techniques

Knee Surgery, Sports Traumatology, Arthroscopy — Tue, 24 Jan 2012 07:34:45 +0100

Abstract The present article summarizes current trends in arthroscopic rotator cuff repairs focusing on the used repair technique, potential influencing factors on the results, and long-term outcome after reconstruction of the rotator cuff. Moreover, different treatment options for the treatment for irreparable rotator cuff ruptures were described, and the results of additional augmentation of the repairs with platelet-rich plasma were critically analyzed. Based on the current literature, double-row repairs did not achieve superior clinical results compared to single-row repairs neither in the clinical results nor in the re-rupture rate. Multiple factors such as age, fatty infiltration, and initial rupture size might influence the results. If the rupture is not repairable,...

Can the pivot-shift be eliminated by anatomic double-bundle anterior cruciate ligament reconstruction?

Knee Surgery, Sports Traumatology, Arthroscopy — Tue, 24 Jan 2012 07:34:45 +0100

Conclusions The double-bundle reconstruction was shown to over-constrain the knee with respect to the intact value, especially closer to knee extension. This review demonstrated that anatomic double-bundle anterior cruciate ligament reconstruction is able to eliminate pathological translations and rotations during the pivot-shift phenomenon, as identified by quantitative measurement systems.

Clamp fixation to prevent unfolding of a suture knot decreases tensile strength of polypropylene sutures

Knee Surgery, Sports Traumatology, Arthroscopy — Fri, 20 Jan 2012 07:04:48 +0100

Conclusion Under microscopic examination, polypropylene sutures were found to be deformed by clamp fixation, while the others were not. Polypropylene sutures can be easily damaged when it is fixed by a clamp during knot tying. Presented data demonstrated that in real surgical situations clamp fixation of polypropylene knots can damage the suture loop and carry the risk of acute failure of repair site during early rehabilitation.

Arthroscopic stabilization for Neer type 2 fracture of the distal clavicle fracture

Archives of Orthopaedic and Trauma Surgery — Thu, 19 Jan 2012 06:59:00 +0100

In this study, we describe the arthroscopic procedure to reconstruct the disrupted ligament and stabilize the fracture as a minimally invasive method. The subjects were seven patients with the distal clavicle fractures. According to Neer’s or Rockwood’s classification on plain radiographs, all seven patients were evaluated as type 2 or 2B, respectively. Our surgical procedure was performed with the patient in the beach chair position. We have used the artificial ligament with an EndoButton (Smith & Nephew Endoscopy, Andover, MA) as the substitute ligament to reconstruct the disrupted conoid ligament. The mean duration of postoperative follow-up was 2 years and 5 months. The bony union was achieved in all patients at a final follow-up. When concerning the range of motion...

Radiographic parameters associated with lateral patella degeneration in young patients

Conclusion It appears that isolated lateral patellofemoral degeneration is associated with specific radiographic indices. Even though the radiographic measures in patients with degeneration may not be considered pathologic, they are “high normal” and may represent a risk factor for the development of focal chondral degeneration in the lateral trochlea and patella.

Arthroscopic decompression of suprapatellar cyst: case report

Knee Surgery, Sports Traumatology, Arthroscopy — Thu, 19 Jan 2012 06:55:58 +0100

Abstract Bursae around the knee reduce friction between moving structures. When involution of suprapatellar septum fails to occur (“complete septum”), then suprapatellar bursa may stay completely separated from the knee joint cavity to form a cystic cavity. In the case of the increased volume, suprapatellar bursitis can cause painful suprapatellar swelling. The aim is to point to the possibility of arthroscopic decompression of suprapatellar cyst. In the case presented, the indication for knee arthroscopy was based on clinical examination, ultrasonography and magnetic resonance studies. The preoperative diagnosis was verified intra-operatively, and intra-articular cyst decompression was performed by arthroscopy. At the final examination 8 months postoperatively, t...

Assessment of Volar Radiocarpal Ligaments: MR Arthrographic and Arthroscopic Correlation

American Journal of Roentgenology — Thu, 19 Jan 2012 05:00:00 +0100

CONCLUSION. With currently established imaging criteria, correlation between MR arthrographic and wrist arthroscopic findings in the assessment of tears of the radioscaphocapitate and long radiolunate ligaments is inconsistent. Because of the increasing clinical importance ascribed to the extrinsic carpal ligaments, further work aimed at refining both imaging techniques and diagnostic criteria in the MRI evaluation of these structures is warranted to improve correlation with results obtained at arthroscopy.
