The objective of this paper was to analyse sex differences of the thickness of the subchondral mineralised tissue zone (SMZ), and to find out whether systematic changes of SMZ thickness are associated with naturally occurring, non-full-thickness cartilage lesions of human patellae. In 32 methyl-methacrylate-embedded specimens (16 normal, 8 with focal medial, and 8 with lateral lesions) the SMZ ...
Background. The patella is the largest sesamoid bone in the body; its three-dimensional complexity necessitates biomechanical perfection. Numerous pathologies occur at the patellofemoral unit which may end in degenerative changes. This study aims to test the presence of statistical correlation between the surface areas of patellar facets and other patellar morphometric parameters. Materials and...
ABSTRACT FOR THE 2008 ISMRM MEETING – Toronto, ON, Canada MR IMAGING OF THE PEDIATRIC KNEE Lecturer:
FOR THE 2008 ISMRM MEETING – Toronto, ON, Canada MR IMAGING OF THE PEDIATRIC KNEE Lecturer: Andrea S. Doria, M.D., Ph.D., M.Sc. Date of Submission: December 7, 2007 A variety of imaging techniques is now available to investigate the growing knee. MRI, however, is playing an increasing role in the evaluation of bone, cartilage, joint space, tendon, soft tissue inflammation and other abnormalitie...
Because we communicate mainly through words, it is important that terms be understood in the same manner by all readers. Unfortunately, the study of the patellofemoral joint is complicated by the use of expressions that hold different meanings for different readers. Ideally, the community of musculoskeletal physicians should agree on a single definition of terms, but until then, authors and spe...
Background and purpose: Anterior knee pain (AKP) is one of the most common disorders in young individuals and adults. Pathophysiology of AKP is not clear but chondromalacia patella is considered as the main cause. Different evidences show that physical therapy can alleviate Patellofemoral pain. Despite these therapeutic modalities the treatment of chondromalacia patella is not accurate and most...
BACKGROUND AND OBJECTIVE Anterior knee pain (AKP) may compromise the results of total knee arthroplasty in more than quarter of cases. The aim of the current work was to determine the prevalence of AKP and the severity of patellofemoral symptoms among patients who received a total knee arthroplasty with non-replaced patella in East-Tallinn Central Hospital from January 1, 2000 to December 31, 2...
OBJECTIVE Whilst the characteristic pathologic feature of OA is the loss of hyaline cartilage, prior studies have demonstrated a poor relationship between severity of reported knee pain and degree of radiographic change. The aim of this study was to examine the association between knee symptoms and MRI cartilage volume. DESIGN A cross-sectional study was performed to assess the association be...
We compared the effects of continuous passive motion with those of intermittent active motion on the results of the resurfacing with autogenous periosteal grafts of full-thickness defects on the articular surface of rabbit patellae. Of 45 rabbits with defects, 30 received grafts. Fifteen of these had continuous passive motion for two weeks and intermittent active motion for four weeks; the othe...
Patellar sleeve fractures make up greater than 50% of all patellar fractures. They are essentially only seen in the pediatric population because of the thick periosteum and the distal patellar pole apophysis in this group. These fractures can lead to complications if not treated appropriately and in a timely fashion. Complications of missed or untreated patellar sleeve fractures include patella...
OBJECTIVE To analyze occurrences of trochlear dysplasia in patients with Down syndrome in the presence and absence of femoropatellar instability. METHODS Eleven knees with stable patellae and thirteen with unstable patellae in patients with Down syndrome were compared. Radiographs were produced to evaluate patellar height, trochlear angle and femoropatellar congruence angle. RESULTS The pre...
