This book was released on 2015 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: The anterior cruciate ligament (ACL) plays a complex role in knee stability. Injury to this structure can cause abnormal joint kinematics and loadings which may lead to the early onset of osteoarthritis (OA) and joint degeneration. While surgeons are able to restore joint laxity in the short to medium term, long term OA development is currently not prevented in patients who have undergone surgical repair. In order to slow or stop the progression of OA following ACL injury, we hypothesize that reconstruction techniques must achieve a greater degree of native ligament functionality. The principles of Functional Tissue Engineering state that a ligament's functionality may be defined as its in vivo loading characteristics. While this information remains impossible to measure directly in human patients in vivo, in vitro testing can serve as an alternative as long as the following conditions are met: 1) Loads are measured in 6 degrees-of-freedom (DOFs); 2) Loads are measured during activities of daily living (ADLs); 3) Loads are measured within a realistic environment, which may include knees sustaining injury to structures influencing ACL functionality. Due to the invasive nature of in vivo load sensing, researchers have turned to robotics to simulate ADLs kinematics on biological tissue. This technique allows open access to the joint to measure contact forces and 6 DOF ligament loads throughout physiologic motion paths, fulfilling the first 2 requirements for in vitro testing. By using an animal model, specimen-specific kinematics may be collected and applied to the same tissue, overcoming several limitations of cadaveric testing, including specimen quality and kinematic mis-matches. It also allows for consideration of biologic effects and controlled testing of various knee pathologies, fulfilling the 3rd requirement for in vitro testing. Because of these advantages, this work utilized robotics in combination with the sheep knee model to study in vivo ACL loading, which may then serve as design criteria for new and novel repair techniques. Studies were designed to address two specific aims. The first focused on assessing the biomechanical relationships between activity and the corresponding demands placed on the ACL. Results showed that, while a strong link exists between activity and the corresponding knee kinematics, the knee dynamics follow a more complex pattern with inter-relationships between multiple DOFs. Overall, ACL functional demands were most variable during phases of the activities when the knee was less weight bearing, yet still engaged. Specifically, inclined gait placed higher demands on the ACL during hoof strike while declined gait place higher demands on the ACL during push off. Both of these time points corresponded to instances of lower compression levels within each ADL. This is also consistent with the timing of non-contact ACL tears, where most injuries occur during the transition from uncompressed to compressed knee states -- such as landing. The second aim focused on assessing biomechanical relationship between ACL demands and concomitant knee injury. Medial meniscus (MM) injury increased ACL forces during the transitions between swing and stance in response to significant increases in anterior translation. Dual (MM and MCL) injury produced no increases, yet both MM and Dual groups developed significant OA within the medial compartment. MCL injury produced increased ACL force during mid stance in response to increased overall joint laxity but no increase in OA. Results of the this study are the first to relate ADLs and injury of surrounding structures to resulting knee biomechanics and ACL function and provide preliminary data for defining design requirements for future ACL reconstruction techniques.

Download or read book Ligaments and Ligamentoplasties written by L'Hocine Yahia and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 588 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite a substantial amount of literature already accumulated on the subject, our understanding of the structure, function, and biology of the cruciate ligaments has yet to reach the point where we can repair this complicated structure. This volume does not attempt to address every aspect of cruciate ligament replacement, but rather chooses to concentrate on the neurological function of the ligaments. It adopts a pragmatic approach to fatigue testing in more physiological conditions, biomimetic designs, European surgical techniques and new approaches derived from tissue engineering. As such, it is the first volume to sufficiently emphasise the progress that has been made outside of North America and follows more closely the SICOT/SIROT philosophy. The first section provides an overview of the increasing amount of knowledge on natural ligaments, while the second one reviews - using a biomimetical approach - the different concepts and designs of artificial ligaments developed over the last few decades. The final section presents new directions to expand our present understanding and suggests future approaches.

Download or read book Revision Anterior Cruciate Ligament Reconstruction written by Michael J. Alaia and published by Springer Nature. This book was released on 2022-06-02 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anterior cruciate ligament reconstruction is one of the most common procedures performed in sports medicine centers. However, these procedures can carry a long-term failure rate as high as 5-15%%, and when these procedures fail, revision is significantly more complex. Considerable factors need to be assessed in patients that are indicated for surgery, as revisions carry a higher failure rate and potentially less optimal outcomes and return to sport and activity. These factors include, but are not limited to, the status of the meniscus, overall alignment, graft options, placement of prior implants or tunnels, collateral ligament quality, and whether or not the revision must be staged into two procedures. This text provides a comprehensive, case-based presentation of the most efficient and practical treatment algorithms for patients in need of revision ACL repair and reconstruction. Opening chapters discuss the initial patient work-up, radiography, surgical indications, graft options, and pre-operative considerations and preparations. The main portion of the book then describes both common factors leading to revision surgery as well as the surgical techniques themselves, illustrated via plentiful operative photos and vivid clinical case material. The management of osteolysis, ligamentous laxity, extra-articular tenodesis, plane correction, and meniscus deficiency, among others, are discussed in detail. Special populations, such as the pediatric patient, the elite athlete and the female athlete, are discussed as well. Shedding light on this challenging surgical repair, Revision Anterior Cruciate Ligament Reconstruction is the go-to resource for sports medicine and orthopedic surgeons, knee specialists and residents and fellows in these areas.

Download or read book Anterior Cruciate Ligament Reconstruction and Dynamic Stability at Time of Release for Return to Sport written by Penny L. Head and published by . This book was released on 2019 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: With an elevated risk of a second anterior cruciate ligament (ACL) injury following ACL reconstruction (ACLR), determining when an athlete can safely return to sport (RTS) is a challenging task for rehabilitation professionals. Lack of dynamic postural control has been associated with ACL injury and reinjury and should therefore be included in the assessment for readiness to RTS. The primary purpose of this investigation was to examine dynamic stability using the Dynamic Postural Stability Index (DPSI) in athletes following ACLR at the time of release for RTS compared to healthy, matched controls. A secondary purpose was to examine how dynamic postural stability is affected in athletes following ACLR when performing a jump-landing task in three different directions. We hypothesized that 1) athletes with ACLR would demonstrate decreased dynamic postural stability at time of release for RTS compared to matched controls, and 2) dynamic stability for athletes with ACLR would significantly differ among the three jump-landing tasks.

This book was released on 2012-12-06 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS)* at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volumes were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 39 (thesis year 1994) a total of 13,953 thesis titles from 21 Canadian and 159 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 39 reports theses submitted in 1994, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.

Download or read book Reconstruction of the Knee Joint written by S. Niwa and published by Springer. This book was released on 1997-04 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than 20 years have passed since the International Symposium on Total Knee Replacement was held in London in 1974. Prosthetic design and operative technique have been greatly improved since then, and there is now an accepted standard concept of total knee arthroplasty. Thirteen years after the London symposium, another international symposium on total knee replacement was held, this time in Nagoya, Japan, in 1987. Its ambitious objective was to push forward the frontiers of continuous investigation and improve ment of total knee replacement. The fruits of the individual efforts presented at the Nagoya symposium were published in a volume of proceedings entitled Total Knee Replacement. In the years since 1987, further investigations have been conducted in various parts of the world regarding prosthetic design, fixation, long-term radiological follow-up, biomechanical evaluation, and biomaterials research. In knee ligament reconstruc tion, rapid progress has been made in the past five years in clinical practice and fundamental research by means of arthroscopic surgery and tissue transplantation, and we have come close to establishing a standard treatment. Under these circumstances, an international symposium on knee joint reconstruc tion was planned for 1994, again to be held in Nagoya, to provide ample opportunity for exchanging information and sharing clinical experience from around the world.
